1. Accurate addition of chemicals
Brewery wastewater treatment often requires the dosing of various chemicals, such as flocculants, coagulants, acid-base adjusting agents and disinfectants. The dosing system can accurately control the dosage of chemicals to ensure the stability of the treatment effect and avoid the waste of chemicals and the side effects of over-dosing.
2. pH adjustment
The pH value of brewery wastewater may fluctuate greatly, through the dosing system can accurately add acid or alkali, quickly adjust the pH value of wastewater to the appropriate range, to provide stable water conditions for the subsequent treatment process, especially in the biological treatment process, the appropriate pH value is essential for microbial activity.
3. Promote flocculation and sedimentation
Brewery wastewater contains a large number of suspended solids and colloidal substances, the dosing system can accurately add flocculants and coagulants to promote the coagulation and precipitation of suspended solids and colloids, significantly improve the solid-liquid separation efficiency and reduce the load of subsequent treatment units.
4. Remove organic matter
Brewery wastewater contains a large number of organic matter, such as sugar, yeast, protein, etc., through the dosing system by adding oxidizing agents (such as hydrogen peroxide, potassium permanganate) can effectively degrade some of the organic matter, reduce the Chemical Oxygen Demand (COD) and Biochemical Oxygen Demand (BOD), to improve the biochemistry of wastewater.
5. Control foam
Brewery wastewater treatment may produce a lot of foam, especially in the aeration tank and biological treatment unit. The dosing system can add anti-foaming agent to control the generation of foam and maintain the normal operation of the treatment facility.
6. Disinfection
In the final stage of wastewater treatment, disinfection is often required to ensure that the effluent quality meets standards. The dosing system can accurately dose disinfectants (e.g. chlorine, sodium hypochlorite) to effectively kill pathogenic microorganisms in the wastewater and ensure the safety of the effluent.
7. Improve treatment efficiency and stability
By precisely controlling the dosage and dosing time, the dosing system can significantly improve the efficiency and stability of the wastewater treatment process. Avoid the fluctuation of treatment effect and equipment failure caused by improper dosage of chemicals, and ensure the long-term stable operation of the treatment system.
8. Reduce operating costs
The automatic control of the dosing system can reduce manual operation and lower labor costs. At the same time, accurate dosing of chemicals reduces the waste of chemicals, reduces the cost of chemicals and improves the overall economic efficiency.
9. Monitoring and optimization
Modern dosing systems are usually equipped with automatic monitoring and data recording functions, which can monitor various parameters (such as pH value, flocculation effect, disinfectant concentration, etc.) in the process of wastewater treatment in real time, and optimize the dosing strategy according to the monitoring data to further improve the treatment efficiency and effluent water quality.
