When used as a "polishing" precipitant, the dosage of a precipitant can be lowered depending on the quantity of metals that are precipitated as hydroxides by pH adjustment. While a pH of 8.5 is normally recommended for the polishing effect -- the pH value will vary depending on the presence of chelating and/or complexing agents in the wastewater.

Aluminum sulfate-flocculant in industrial wastewater

Aluminum sulfate is generally used in papermaking or as a flocculant in industrial wastewater treatment. The standard aluminum sulfate evaporation crystallization technology uses a single-effect evaporator for atmospheric evaporation and concentration. The system has low evaporation intensity, high operating costs, and a poor operating environment.

coagulants and flocculants for liquid solids separation

Coagulants and Flocculants for Liquid Solids Separation

Flocculants are commonly used with coagulants and are a substance that helps the clumping of fine particles into a "floc", especially in the treatment of wastewater. Flocculation is the process in which colloids — low-diameter particles that affect water's color or turbidity — are suspended in the form of loosely clumped particles called flocs.

PROCEDURE: 1. Pour a sample of untreated wastewater into a beaker (ex 300 ml). While mixing, adjust the pH using caustic soda or sulfuric acid to the optimum pH for hydroxide precipitation of mixed metals, i.e. pH 8.5. 2. While stirring the sample, use an eyedropper to add the precipitant until the ORP value drops rapidly by 150mV (typically to
