coagulate, raw water turbidity. Lime sludges cannot be returned to the environment, so dewatering or lagoon storage is required, all coagulants should be evaluated with respect to their ability to dewater on the equipment in the water plant. The major criteria for efficient lime softening is pH control, pH should be maintained at 10.0 ± 0.2. A metal based

Measure 900 mils water and add your choice of 1% or dry milk. Stir the mixture and add the acid while stirring. Let settle. Some floc may settle and some may float. The water will stay cloudy, but most of the milk proteins will coagulate under acid conditions. If there is too much milk, the proteins will not separate.

Deli Meats Processing Wastewater Treatment System Process ...

Deli Meats Processing ,wastewater, is treated by adjusting pH downward using ,acid, and strong coagulant chemistry to break emulsions caused by cleaning agents and sanitizers. The pH is then raised to ~8.5 with a coagulant added to precipitate and ,coagulate, solids and fats. A flocculent is then used to increase particle size and assist in separation.

Electrocoagulation - Wikipedia
Electrocoagulation - Wikipedia

In the EC process, the coagulant is generated in situ by electrolytic oxidation of an appropriate anode material. In this process, charged ionic species—metals or otherwise—are removed from wastewater by allowing it to react with an ion having an opposite charge, or with floc of metallic hydroxides generated within the effluent.

Treatment of the flexographic wastewater is done by first lowering the pH to ~ 2-3 pH using acid to break the emulsion. The wastewater is then pH adjusted upward to ~8 using caustic to begin the precipitation process. Some difficult ink wastewaters may require coagulants. The ink and other solids in the wastewater will coagulate.
