Description

Automatic chemical supply device for water treatment}

The present invention is a technology related to an automatic chemical supply device for water treatment, and it is possible to reduce chemical costs by injecting chemicals in a scientific and quantitative amount compared to manual chemical injection by non-experts according to changes in inflow water quality in general chemical injection used in the water treatment process. And, it relates to an optimal automatic chemical supply device for water treatment that can reduce labor costs by actively coping with changes in raw water quality without requiring users and managers to work full-time 24 hours a day.

Unless otherwise indicated herein, material described in this section is not prior art to the claims in this application, and inclusion in this section is not an admission that it is prior art.

In order to treat influent raw water such as wastewater containing suspended solids (SS) and purified water containing turbidity substances, a treatment process to remove suspended solids (SS) or turbidity (NTU) is required. Such turbidity (NTU) or suspended solids (SS) treatment is also required in a water treatment process for producing tap water or a water treatment process for treating waste water. Main water treatment is neutralization, coagulation, flocculation, precipitation, and filtration processes, and among these, the case where the chemicals injected in the coagulation and coagulation process can be divided into the same case and the case where they are different.

Generally, in the neutralization process, the chemical amount of the neutralizer can be controlled by the pH meter and controller, but in case of condensation and coagulation, the injection amount of the chemical is determined by the Jar Test and the chemical is injected manually. In order to optimize condensation and flocculation, it is necessary to properly inject the amount of chemicals according to the concentration of influent raw water.

In order to identify the concentration of influent raw water in the water treatment process, it is measured with a turbidimeter or suspended matter measuring system, and a manager is placed to manually inject chemicals through Jar Test or visual observation. The injection volume should be adjusted.

Therefore, if the manager does not reside 24 hours a day, it is difficult to actively cope with the concentration change of the incoming raw water and it is difficult to inject an appropriate amount of chemicals, which can cause considerable problems in water treatment. In addition, if you are not an expert in water treatment, you may not be able to properly adjust the optimal injection amount of chemicals, which may affect the efficiency of water treatment and consume a large amount of chemicals.
