polyaluminium chloride dosing effects on coagulation performance: case

Polyaluminium chloride dosing effects on coagulation performance: case

The effects on the treatment process of three different sets of mixing speed pairs ¨C 180/40, 180/25 and 150/25 revolutions per minute (fast/slow) ¨C in a pH range of 6.5 to 8.0 were investigated. The mixing speed and PAC dose yielding the best coagulation were 150/25 rpm and 15 mg/L respectively.

powdered activated carbon (PAC) reagent used in water treatment

Activated carbon can be decompacted by installing an "intermediate hopper". A transfer screw or a rotary vane feeder feeds the hopper. The feeding system is mounted on the ¡°intermediate hopper¡±. Once the PAC has been decompacted, a volumetric feeding (screw-type feeder) then becomes feasible. PAC is a product having a widely varying density

1. Introduction. Powdered activated carbon (PAC) adsorption is a powerful and easily adjustable technology due to the effective removal of many contaminants [1,2,3].The process of PAC adsorption to remove aquatic contaminants from natural water can be described with a three-step transition, i.e., from water to carbon, then to the carbon surface, and finally to the binding sites [].

Coagulation water treatment: Which coagulants are best for your facility?

The optimal pH range of aluminum sulfate is between 5 and 7.5, which means the coagulant performs at its best in slightly acidic or neutral solutions. Ferric chloride may be a better option for coagulation below this level of pH, while ferrous sulfate may be suitable for the treatment of more alkaline water. Sodium aluminate.
