USING POLYALUMINIUM COAGULANTS IN WATER TREATMENT
From Table 1, it will be noted that polyaluminium coagulants are typically twice the price of liquid alum on per kilogram aluminium basis. However, lower doses of the coagulant and lower pre- and post-treatment alkali doses can still make its use economical.

The BSF process improves the sedimentation speed and overflow rate, reduces the footprint of the system, and greatly reduces the cost of coagulation treatment. Many researchers have conducted in-depth research. For example, Desjardins 17 conducted comparative experiments in three different water treatment plants, and the results showed that the amount of coagulant was the key parameter that ...

Turbidity is one of the major problems in the treatment of drinking water. Turbid water contains molecules, plankton, and colloids, and is dealt with through the addition of coagulation chemicals in processes called coagulation and flocculation. In this research, three of the most commonly used coagulants utilized in the process of turbid water treatment are examined for their efficiency in ...

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. […]
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.
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).
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.
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.
Which coagulant has better turbidity removal efficiencies?
The results show that there are no significant differences in removal efficiencies of turbidity and color between the two coagulants under study: PACl + FeCl 3 and PACl. Though, comparatively the coagulant PACl + FeCl 3 shows better color removal efficiencies, while the coagulant PACl shows better turbidity removal efficiencies.
