Abstract:
Nestle Bangladesh has settled their factory in Sreepur, Gazipur which is very close to the preserved forest ,
a cantonment & a local community. Despite having heavy rainfall & surrounding by rivers the Sreepur
upazilla is classified extremely high in terms of over all water risk as per AQUEDUCT tool of WRI (World
Resource Institute). The Nestle Production facility in Sreepur is situated in this water stressed area. The
management of water & Waste water is extremely important for this production facility.
Nestle Bangladesh is the leading FMCG MNC company in Bangladesh & following all the rules, regulation &
compliance of all local & international rules & policy. Very recent the government of Bangladesh &
Department of Environment has implemented a Zero Liquid Discharge (ZLD) policy to address industrial
wastewater discharge. Under this policy, industries are required to treat and recycle their wastewater to
ensure zero discharge into water bodies. So in this research we will do the feasibility analyis of ZLD &
implementation to achieve zero detrimental effect on surrounding Environment.

Introduction:
Zero liquid discharge is the strategic waste management system which ensures zero negative impact on it’s
surrounding water bodies & soil. It is achieved by treating waste water through recycling, then recovery & reuse
for industrial purpose. As this concept is new in Bangladesh & very few industry work on it. As this waste
management will be an exemplary milestone to preserve our nature, environment & model for many industries
so have taken this initiatives to implement the concept. If we do not take this step in the coming years, we will
fall in a deep trouble as the level of ground water is increasing day by day & we will not get fresh water in the
coming days easily & might pollute the surface water & aquifers such a way that the resource will become a
threat for our next generation.
Problem Statement
• The maximum industry of Bangladesh are not following the norms of the DoE Standards during
effluent treatment & this ignorance make the waterbody vulnerable for future as both surface
water & ground water polluted and the eco system & biodiversity also affected.
• As the zero liquid waste discharge is a close control loop of technology which will not discharge
any portion of waste water towards outside of the factory boundary will surely keep the theme of
environmental conservation as well as water conservation of the country.

Rational of the Study
We are living in a time where we have already polluted our surroundings & to save from further
pollution work like Zero liquid Discharge will surely provide a green revolution in the field of
industrialization. The people living surrounding the industrial & urban area will be benefitted.

Literature Review:
Mostly the research are accomplished in abroad other than Bangladesh &
some are executed in a very small scale in lab, Nusrat Jahan et all:a. Some
research are as on case study suggest four ZLD Process to be added centrally
to ensure zero liquid discharge from several textile industry Ahmed et al:b.
hypothetically These unit processes incorporate all the different treatment
units discussed above and provide an environmentally sustainable solution
by reclaiming water and salt for reuse in the manufacturing processes of the
RMG industry. From the research of M. R Chowdhury et All:c the concepts of
ZLD is not well accepted by the textile owners. My research will be to
implement the ZLD System in my factory where Industrial waste water
treated through ETP & STP & the effluent water is recycled & reuse in
different process of the industry & the solid waste kept as fertilizers for
Industrial gardening purpose.
Methodology of the Study:
Waste water treatment plant & sewerage treatment plant functionality of Nestle Bangladesh will be assessed
as per national, international regulations, guideline, standards etc. All efforts will be given for collecting the
accurate data and measurements. Due care will be given to help the analysis team to take the data at any time
& both inhouse & reputed 3rd party vendor will be engaged to analysis all the parameters. We will use
engineering, chemical & biological methodologies to produce the result.
At present the influent water treated with membrane reactor & RO the permeable water after treatment
discharged to outside following the norms of DoE & Sewerage water after treatment through STP discharged
outside. We are planning to further processing this discharged water through RO & recirculate the water to
cooling tower for further close loop processing & treated STP water which is RO reject water that will be
recirculated to gardening & toilet flushing.
Comprehensive checking of inlet & outlet water as well as various subprocess will be checked internal facilities
& external bodies (DoE, 3RD Party Vendor)
Further socio-environmental condition will be surveyed to ensure that this ZLD Process maintain the
Department of Environment standards & net detrimental effect towards environment is zero. Which means
there is no adverse effect on the surrounding communities & environment.
The sludge from ETP & STP are treated as manure & will be treated as fertilizers for inhouse gardening which
will meet the criteria of classification as ‘Green’ waste under the Bangladesh Standard & guidelines for sludge
management.

Methodology of the Study:
The parameters will be checked: (Quantative analysis)
1. DO
2. BOD
3. COD
4. TDS
5. TSS
6. Consumption of water data 2023 & 2024
Instruments:
7. Digital Water Analyzer Meter
Method:
Inhouse facilities & 3rd party evaluation will be cross check to ensure the efficiency of the research.

reactor-RO-MEE Systems, (c) Chemical coagulation-Aeration-RO-MEE System, (d) Electrochemical electro coagulation-Membrane filtration-MEE
System. These unit processes incorporate all the different treatment units discussed above and provide an environmentally sustainable solution by
reclaiming water and salt for reuse in the manufacturing processes of the RMG industry
