Waste Water Treatment › Chemical Treatment of Wastewater
They are designed to handle acid and alkaline waste solutions.
Since direct discharge of wastewater after chemical processes will be harmful, pH adjustment systems are effective in complying with the criteria of wastewater discharge regulations. Ideal methods are acid and caustic additions. Acid or caustic pH is dosed to reach the desired level.
It consists of neutralization systems, balancing tank, pH meter, treatment chemicals, metering pumps, double diaphragm pumps and control panels.
The balancing tank allows the pH to neutralize itself and equalizes the temperature of the various flows. An inlet downpipe or baffle is used to direct the flow to the bottom of the tank. Chemicals from metering pumps are fitted with injectors.
Caustics are used in concentrations of 20-50%, acid at concentrations of 50% and above. Regardless of the type of treatment, the more preliminary data can be collected, the smoother the system will run.
