Is polyaluminium chloride a safe coagulant?

Polyaluminium Chloride is a safer alternative to several other chemical coagulants. For instance, aluminium sulphate has been widely used as coagulant for many years. It removes contaminates and general turbidity from water during the water treatment process.

Which coagulant has the lowest cost?

Namely, coagulant PACl + FeCl 3 shows the lowest cost and the highest efficiency during its use in the drinking water treatment plant under study. The cost-benefit ratio of coagulant PACl + FeCl 3 is 1.19 times lower compared to the coagulant PACl. Content may be subject to copyright. […]

Can coagulants be used in a drinking water treatment plant?

The main objective of this paper is to show a cost/benefit analysis for the use of different coagulants in a drinking water treatment plant in a developing country. The coagulants evaluated are aluminum hydroxychloride (PACl) + ferric chloride (FeCl 3) and aluminum hydroxychloride (PACl).

Which coagulants are used in drinking water treatment?

The coagulants evaluated are aluminum hydroxychloride (PACl) + ferric chloride (FeCl 3) and aluminum hydroxychloride (PACl). The efficiencies of turbidity and color removal of each coagulant and the associated costs of dosing these inputs for drinking water treatment are studied.

What is the cost-benefit of coagulants PACL & FECL 3?

Findings show that the cost-benefit of the coagulants PACl + FeCl 3 and PACl are 0.723 USD/% and 0.857 USD/%, respectively. Namely, coagulant PACl + FeCl 3 shows the lowest cost and the highest efficiency during its use in the drinking water treatment plant under study.

What is polyaluminium chloride used for?

Among the aforementioned products, polyaluminium chloride has become one of the most effective coagulant agents in water and wastewater treatment facilities with various applications, including removal of colloids and suspended particles, organic matter, metal ions, phosphates, toxic metals and color.
