polyaluminium chloride dosing effects on coagulation

Polyaluminium chloride dosing effects on coagulation

Tools Abstract Listen Alum, the predominant coagulant in conventional drinking water treatment schemes, has various disadvantages including the production of large volumes of sludge, lowering water pH (requiring pH adjustment using lime), limited coagulation pH range of 6.5 to 8.0, etc.

USING POLYALUMINIUM COAGULANTS IN WATER TREATMENT - WIOA

Typical aluminium-based coagulants used in water treatment At one water treatment plant in the Otway region of Victoria, polyaluminium chloride replaced alum and in so doing SO4 levels in the treated water were reduced from 27 to 4 - 5 mg/L. Previously, alum was dosed at 45 to 55 mg/L at this plant.

Polyaluminum chloride (PAC) ¨C Al12 (OH)24Cl12 (Just one of a number of different formulae ¨C this is the most common form of polyaluminum chloride used in water purification.) Polyaluminum chlorides ¨C or PAC ¨C make up a grouping of different compounds, many of which are suitable for coagulant applications.

Prediction of the optimal dosage of coagulants in water

Coagulation and flocculation are the prominent processes and unit-operations in water treatment plants. One of the most challenging operations in water treatment process is determining of the coagulant dose. Method The Jar-test method is usually used to determine the coagulant dose.

DelPAC? (Polyaluminum Chloride Solution) - USALCO

DelPAC 2020, when used as a coagulant, can provide longer filter runs, reduce or eliminate the need of alkali for pH adjustment, lower amounts of residuals and generally has a lower overall cost when compared to other treatment programs.

Prediction of the optimal dosage of coagulants in water

The results of modeling by ANFIS with correlation coefficients of 0.85 and 0.84 and RMSE 1.32 and 1.83, respectively, for alum and polyaluminum chloride (PAC) coagulant dose, indicated that ANFIS is an effective method for determination of the optimal coagulation dose in the water treatment plant.

In addition, PAC has been gaining more attention as a coagulant in the water industry for its ¡°bridging¡± ability and lesser sludge production . The co-treatment using PAC and FeCl 3 certainly improved the phosphate removal compared to the mono-treatments, with 90¨C95% efficiency for dose 1 and 99% for dose 2 (Figure 1).
