sterilization by flocculants in drinking water treatment

Sterilization by flocculants in drinking water treatment

? Two flocculants played the different roles in drinking water treatment. ? The synergistic effect of two coagulants for sterilization was confirmed by Contour Method. ? Sterilization mechanism and kinetics of flocculants were revealed for the first time. ? Sterilization was divided into two processes, rapidly adsorbing and slowly killing. Keywords

polyaluminium chloride dosing effects on coagulation

Polyaluminium chloride dosing effects on coagulation

Aluminium sulphate (Al 2 (SO 4) 3), commonly called alum, has long been used as a coagulant in conventional water treatment but has numerous disadvantages including the production of large volumes of post-treatment sludge, high post-treatment aluminium residue, limited coagulation pH range of 6.5 to 8.0, etc, associated with its use (Gebbie

The new life of traditional water treatment flocculant

Polyaluminum chloride (PAC) is an inorganic polymer material that has the advantages of a simple preparation process and special electronic structure. It is considered to be the most efficient and widely used flocculation material for water treatment. In this work, PAC has been used as a Lewis acid catalyst in inte

Accordingly, the removal efficiency decreases significantly. Under the pH ranging from 6.0 to 8.0, the positively charged cPAM can fully interact with the negatively charged PSAM and impurities. These results indicated that the developed flocculants were suitable for drinking water treatment under neutral, weak acid, and weak alkaline conditions.

Coagulation/flocculation prior to low pressure membranes in

Coagulation/flocculation is a commonly used pretreatment method for the reduction of membrane fouling; in this review it has been grouped into three typical configuration types: Type 1: coagulation + no/incidental flocculation, Type 2: coagulation + flocculation, and Type 3: conventional coagulation, based on operational conditions.

Predicting flocculant dosage in the drinking water treatment

Predicting the flocculant dosage in the drinking water treatment process is essential for public health. However, due to the complexity of water quality and flocculation, many difficulties remain. The present study aimed to report on using artificial intelligence, namely, the Elman neural network (ENN), to predict the flocculant dosage and explore the applications of the proposed model in
