SECTION ONE
The Climber screen (LX) is a bar screen designed to remove debris such as rags, sticks, etc. from raw sewage. The amount of screenings removed from the waste stream is determined by the slot width of the screens. The LX bar screen features a self climbing screen carriage which carries the raking mechanism without the need for chains or steel cables. The screen carriage remains above the water surface at all times. Operation In operation, the screen carriage is driven by cog wheels traveling up one side and down the other of a vertical double sided track. A series of double rollers traveling in guide tracks create a geometrically simulated raking motion. As the rake descends it is held out from the screen until it reaches the point near the bottom of the screen where it moves in an arc to push the rake teeth into the slots of the screen. At that point the rake starts its ascent and rakes the screen clean at a rate of 6-8 m/minute. The rake then continues to move up the dead plate until it reaches the discharge chute where a stripper blade pushes the screenings off the rake and into the chute. The screen carriage continues to the top of the screen where it changes sides and pauses until the next cycle is requested. The rake arm is spring loaded so that it will rise and move over immovable obstructions caught in the bars rather than damage the drive unit.

The Fine Stepping Screen (FSS) is a robust unit made in stainless steel 304 or 316. Emphasis has been placed on reliable performance and ease of maintenance. The screening lamellas are anchored in place along the whole length of the unit ensuring rigidity and accurate spacing. However, the unique fixing arrangement allows for easy exchange of individual blades should the need arise. Standard slot widths for the screen are 3mm or 6mm with standard screen sizes. Other dimensions are tailored to fit the requirements of the plant. Application The FSS designs have been developed using the experience of hundreds of fine screen installations around the world in sewage treatment, sludge and industrial applications. This experience is vital in providing appropriate screening solutions for every situation.

Dimensions and capacity The tables above show key dimensions for the FSS screen range (as denoted by the drawing) and typical capacities in litres per second, for raw sewage flows. The figures are per 100 mm of screen width for each of the standard sizes and slot widths. 20% clogging of the screen due to the screenings has been assumed and a head loss (difference in water level before and after the screen) of 200 mm. Capacities will vary according to the application and operating conditions of the unit.
Advantages The FSS is long established as a leading solution for the removal of solids and fine particles from flows and, in particular where difficult materials are involved. The screen design consists of evenly spaced stepped lamellas which trap solids and fine particles but allow liquid to pass through. The solids build up on the lamellas rotate lifting the mat step by step up the screen to be discharged at the top. This lifting action, coupled with the retention time on the screen, produce highly dewatered screenings. The high open area of the screen and single pass through by the liquid lead to a high capacity per unit area and low head loss.

Operation Wastewater is passed through the sieve inlets of the rotary drum screen. Screenings, which are larger than the screen slots, will be blocked and removed by the scraper blade to a container. The influent will then pass through the sieve and out through the bottom. Particles which are not removed by the scraper blade will be washed away by the filtered water from the wire sieve. This creates an efficient internal self-cleaning system. Optional A water-jet spray system can be installed when frequent cleaning is required. It can be fitted with a solenoid valve for easy control. Screen Dimensions (mm) Type A TS 63 TS 66 TS 612 TS 618 250 554 1139 1882 B DN 100 DN 150 DN 250 DN 300 C DN 200 DN 250 DN 350 DN 400

Advantages Shaftless screw conveyors are accepted as the leading method for the transportation of difficult materials (eg. wet pulp, fibrous or sticky substances). In addition, the fully enclosed system means effective, safe and silent transportation in a clean and odorless environment. The absence of a shaft and intermediate bearings minimizes the risk of clogging. Application The thousands of installations ML has completed worldwide include transportations of screenings, dewatered sludge, grit and sand from sewage treatment and applications in the food, chemical and paper and pulp industries. Standard Design The conveyors are produced from standard components tailored to the requirement of each site. The troughs, available in stainless steel 304 or 316, have a wear resistant liner selected according to the application and duty. Most commonly used are ultra high molecular weight polyethylene (with optional indicator layer), polyurethane or hardened steel wear bars. Spirals are manufactured using speciality steel (or stainless steel) and a cold forming technique to optimize strength. Longer or heavier duty conveyors are supplied with inner spirals to increase axial strength and capacity. Single units up to 20 meters in length can be delivered with push or pull drives depending on the material conveyed.

Screw Conveyor with Dewatering Unit (SCD) Application Shaftless screw conveyors can be supplied with a dewatering zone for removal of liquid and any suspended or dissolved matter (e.g. organics) from wet or sticky materials. An increase in the dry solid content and, therefore, volume reduction, in the conveyed material of up to 75% can be achieved depending on the application. ML has hundreds of installations of the SCD screw conveyor with dewatering unit for sewage treatment and industrial processes. The unit is ideal for combination with ML's fine screens for recovery of organics and drying of screenings. Standard Design The dewatering unit, which consists of a fine wedge wire screen and flushing system can be used with all ML's shaftless conveyors. A weighted, hinged outlet gate allows effective discharge whilst avoiding odour problems. A double spiral is supplied as standard for increased axial strength and capacity. Options Additional options, beyond those available for standard conveyors, include insulation for the dewatering zone and a bagging unit for hygienic disposal of material directly into sealed sacks. Capacity For standard applications the capacity of the screw conveyor is unchanged by the addition of a dewatering unit. SCD 480, length 2.5 m

The Grit Classifier is used efficiently for removal of grit or other settable particles with high sinking speed from the inflow of the Sewage Treatment Plant. It is a simple but effective equipment for trapping the settled particles and transporting them efficiently by a shaftless spiral screw conveyor into the collecting skip. Operation The Grit Classifier (SD) can be located adjacent to the point of collection. The Classifier is designed to receive grit and water mixture from gravity or pump rising main. The inlet (1) is specially designed to minimize turbulence of the inflow thus creating an optimum flow pattern for sedimentation to occur. The solids that settle to the bottom are elevated at extremely low speeds through a shaftless spiral housed in the trough (5) at an inclined angle. The settled grit remains in the spiral screw and dewaters itself as it gets elevated until the discharge outlet (2). The floating solids and the liquid overflow back to the main sewage channel through outlet (3). Design Features

Rotary Drum Thickeners
The Rotary Drum Thickener is designed to concentrate or thicken thin sludge with solids content as low as 0.3 %. By reducing very considerably the volume of the sludge it increases the capacities of existing treatment equipment or reduces the size of proposed new installations. The Rotary Drum Thickener has virtually no limitations as to the type of sludge which it will dewater. We detail a few examples below : Primary Sludge Digested Sludge Activated Sludge Mixtures of any of the above Industry Sludge In the case of dewatering sewage sludge, they must be first flocculated in a Reactor (Polymer Floc Tank) and then fed gently through the slowly rotating thickening drum. The free water drains through the steel or polyester mesh by gravity. With the very high solids capture rate of 98% plus the filtrate can be recycled for use in the spray water system which is required for the continuous mesh cleaning, thereby removing the requirement of a fresh water supply. The Rotary Drum Thickener is a development of the conventional gravity thickeners with regards to construction and process and is a fully automatic and continuous system. Advantages
Cost Effective All moving parts slow moving Small area requirement Energy efficient Environmentally friendly All stainless steel construction, if required Totally enclosed Easily removed panels Gear drive with slew ring bearing
Applications As a concentrator in sludge thickening process For pre and post thickening of digested sludge As a pre-dewaterer before belt filter press For the separation of floating sludge As a fine screen when fitted with a different filter media As a Milliscreen when fitted with a wedge wire drum

Zickert Sludge Scrapers
Z 2000 Bottom Sludge Scraper The Z 2000 hydraulic scraper is a bottom sludge scraper specially designed for continuous transportation of sludge. Z 2000s have been used with success in a number of different types of sedimentation system. The scraper consists of an hydraulic piston inside a cylinder, a lever system and a number of wedge-shaped sections welded together to form a single unit so that they function as a moving floor over the bottom of the tank.
Simple to install, simple to maintain The design and structure of the Z 2000 has been kept as straight forward as possible, which means that it is simple to install. No lifting devices or other complicated equipment are required. Components for standard scrapers are always held in stock. This means that we can install a completely new standard scraper in the course of 1-2 weeks. The total time taken to install a 20 x 6 m scraper on site is usually 2-3 working days. The maintenance required is minimal. The few moving parts and small forces involved mean that the strains to which the scraper is subjected are also small. There is relatively little friction between the scraper and the bottom of the tank, since the sections run along strips made of high-density polythene. The power required to drive the scraper along the bottom of the tank is very low, and the hydraulic unit operates at low pressure. These factors make for sensitive operation and long economic service life. Except for the strips, all materials submerged in the water are stainless steel.
The forward and return movement of the sections is powered by the hydraulic system. When the sections move forward, they transport the sludge with them to the sludge pit. During the return movement, the points of the wedges slide under the blanket of sludge, so that its top layer flows over them. The speed of the return movement is approximately three times that of the forward movement, to give continuous transportation of the sludge. Where the sludge has such a low total solids content that no blanket is formed, the sections scrape a stream of sludge along the bottom of the tank. The repeated movements of the sections have the effect of thickening the sludge, thus increasing its total solids content while at the same time guiding it towards the sludge pit. Easy to adapt for use in existing tanks The design of the Z 2000 allows considerable latitude where positioning of the hydraulic cylinder is concerned. Whether drawn or propelled, the scraper will produce the same results. It is even possible to position the cylinder horizontally below the surface of the water, in which case the number of moving parts is reduced from four to one. Nor does the bottom of the tank need to be level for the Z 2000 to produce good results. It should, however, be either horizontal or slope towards the sludge pit.
The sections are welded together to form a single unit, so that they function like a moving floor over the bottom of the sedimentation tank.

TECHNICAL SPECIFICATIONS Z 2000 Applications Rectangular sedimentation tanks in local authority waste water treatment plants, drinking water purification plants and industrial waste water treatment plants. Also suitable for use in conjunction with lamella systems or in flotation tanks. Suitable for use with most types of sludge with a dry solids content of 0,5% to 8% Length = 80 m and Width = 12 m, maximum scraper area = 750 m2 A predetermined number of sections are attached to either 3 or 5 flat steel bars, and the whole is then welded together to form a single unit resting on slides. By means of a system of levers attaching the scraper to the hydraulic cylinder, the whole scraper slides gently forward approx. 700 mm, transporting the layer of sludge in the direction of the sludge pit. The scraper then returns at approx. three times the forward movement. During the return movement the sections slide under the blanket of sludge so that the sedimentation process is not interrupted. The result is continuous transportation of sludge in the direction of the sludge pit. 650 mm 50 mm Stainless steel (AISI 304) or acid-resistant steel (AISI 316)

Zickert Sludge Scrapers
Z 3900 Surface Sludge Scraper The Z3900 sludge scraper is designed for efficient removal of surface sludge with a minimum of transportation water. It is suitable for use in most applications in which surface sludge occurs, including both local authority wastewater treatment installations and industrial process waste water treatment systems, and is easy to adapt for use in flotation tanks or where lamella systems are in use. The scraper is simple to install, is reliable in operation and has few moving parts. The scraper blade draws off the whole of the tanks surface, transporting the sludge to a scum pipe or trough. The Z3900 is characterized by its step-by-step movement. The drive bar moves forwards and returns, the blade being fastened to a slide that is moved forward stage by stage by the drive bar. A system of levers on the slide changes its direction of movement when it reaches its end position. Thus its possible to install several blades in series in one and the same tank, the sludge being passed from one blade to the next on its way to the scum pipe. Each blade is angled upwards 90 during its return movement, to ensure that sludge does not accompany it.
Only the blade itself comes into contact with the surface of the water. On reaching its limit position, after emptying the sludge the blade is angled up for its return movement. Several blades in series can be installed in one and the same tank.
TECHNICAL SPECIFICATIONS Z 3900 Applications For use in rectangular sedimentation tanks in local authority waste water treatment plants, drinking-water purification plants and industrial process waste water treatment plants. Also suitable for use in combination with lamella systems or in flotation tanks. Suitable for use with most types of sludge.

Submersible Aerators
Flygt's range of submersible aerators adopts a superior proven technology in handling municipal and industrial waste water. Adapted and modified to local and international conditions, the Submersible Aerator has been in use for a number of years. A Simple Principle In every Flygt Submersible Aerator, a star-shaped turbine impeller draws in air via a flanged air intake pipe. At the same time, water enters through openings between the motor and aerator housing. This becomes thoroughly mixed with the incoming air before being discharged at high speed through a radial series of diffusers. A Better Solution Flygt Submersible Aerators have distinct advantages over more traditional systems. Oxygenation efficiency is exceptionally high. There is also a good degree of flexibility too, as the range of units available ensures that whatever your operating conditions, we can offer the right oxygenation capacity. Most importantly, the aerator's major components are 100% stainless steel. Installation The Submersible Aerator is normally installed in a stationary position at the bottom of the aeration tank, where it is supported by its own weight, its low centre of gravity ensuring greater stability. Alternatively, it can be attached to a float or raft for the aeration of lakes, pools, large lagoons and rivers. In both instances, the units can be easily installed or removed for periodic maintenance and inspection. Fields of Application Activated Sludge Plants To replace existing aeration equipment during breakdown or long term maintenance. To create and maintain a viable biological treatment capability in new plants. Industrial Effluent Treatment Plants To upgrade existing treatment capacity without major capital investment. To create and maintain a viable chemical and biological treatment capability in new plants. Fish Farms To increase oxygen levels vital for successful fish breeding. River and Surface Water To meet emergency oxygenation requirements. To generally upgrade water quality. Advantages at a Glance
Significant energy savings resulting from high oxygen transfer efficiencies plus intensive agitation during operation. Ease of installation and maintenance. Reduced likelihood of blockage. Low noise disturbance due to submerged operation. No health hazard from splashing of waste water. All weather operation.

The man handling of sludge cake is a well known environmental and health problem in small and medium sized sewage treatment plants. Even with improved ventilation in most screening and press building, a high concentration of bacteria and fungus spores can develop. These factors can produce poor air quality; this can lead to an unhealthy working environment and result in increased proneness for chronic asthma, allergies and diseases in the pulmonary tissues and the intestinal tract.
