Polymers for chemicals that are indispensable in every wastewater treatment system and especially create the most favorable conditions for the efficiency of the sludge press. Whether you are using a filter press, a belt press, a screw press or a decanter. In many specific industries, if you do not mix this type of solution, it is difficult to optimize the process of dehydration and solids in the clarifier. The polymer helps the slurry press to operate at its best by pulling the molecules together and separate from the water component, eliminating obstacles and certain difficulties when pumping the dilute slurry mixture onto the machine. in many industries such as: seafood, textile dyeing, chemical glue, paint and printing ink, the machine cannot work if the sludge moisture is still high,
The following KS Boiler Technology Co., Ltd. helps you better understand the task of polymers with multi-disc screw slurry presses , they are used for physico-chemical treatment processes to increase the flocculation ability of wastewater. . Thanks to this polymer chemical, the flocs formed will be larger, create a higher settling efficiency, and the treated water will be clearer. Therefore, the water separation and recovery is easy, the sludge cake after pressing achieves high dryness, significantly reducing both weight and volume, saving transportation costs.
On the market today, there are two popular polymers: Cation (positive ion) and Anion (negative stainless steel), each with different compatibility for the wastewater characteristics of each industry. There are jobs that use only one type, but there are also cases where a combination of both types is used to help the mud press run smoothly with the maximum amount of solid residue. Some of the following lists will help you to gain more experience in mixing polymers classified by chemical properties:
- Saltwater wastewater: In this water environment, people use anionic polymers or they can use cationic polymers, but the recommended concentration is very low, because the molecules that need to coagulate are usually positive ions, typically metal ions such as Mn, Fe, etc.
- In industrial wastewater, factories producing: wastewater often mix both anionic polymers or cationic polymers because there are many negative and positive ionic impurities inside.
- Wastewater in urban areas, cities and residential areas: mainly using cationic polymer coagulation combined with a small amount of anions.
- Toxic wastewater from industries such as acid, caustic soda, cleaning chemicals, textile dyeing,…
