Does anionic polyacrylamide improve the coagulation–flocculation process?

The use of anionic polyacrylamide had little effect on this cost but improved the coagulation–flocculation process, leading to a significant increase in the settling speed and reduction in the volume of sludge produced. Table 7.

Can anionic polyacrylamide be used as coagulant aid with ferric sulphate and polyaluminium chloride?

It is important to point out that the optimal coagulant dose can be reduced when anionic polyacrylamide is used as coagulant aid with ferric sulphate and polyaluminium chloride, thus decreasing treatment costs. 3.10. Mechanisms of the process

What are flocculants & Coagulant aids?

Up to now, a wide range of flocculants (also known as coagulant aids) have been developed or designed to improve the flocculation process in wastewater treatment including synthetic or natural organic flocculants and grafted flocculants.

How to improve the coagulation–flocculation process applied to a slaughterhouse wastewater?

The aim of this study was to improve the coagulation–flocculation process applied to a slaughterhouse wastewater by adding a coagulant aid (anionic polyacrylamide). The proper determination of coagulant type and dosage will not only improve the water characteristics, but also decrease the settling time and cost involved. 2. Materials and methods

Can coagulation-flocculation process be used to treat ceramic-tile wastewater?

Finally, the results of this study show that the coagulation–flocculation process as well as the PAC combination with anionic, cationic, and nonionic polymers can be used as an effective method for treatment of ceramic-tile wastewater.

What are coagulants & flocculants?

Chemical coagulants and flocculants The conventional chemicals that are widely applied in industrial wastewater treatment can be classified into two major groups: inorganic mineral additives/metal salts which are used as coagulants and organic polymeric materials that are employed as flocculants.
