Is there an alternative preparation procedure for polyaluminium chloride (PAC)?

An alternative preparation procedure for polyaluminium chloride (PAC), a common inorganic coagulant, is presented in this paper.

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 granular al be used to produce polyaluminium chloride?

An alternative way for the production of PAC should be desirable, resulting in a more effectively preparation route, regarding time and cost. In this paper, an alternative method for producing polyaluminium chloride is presented, based on the use of granular Al, as aluminium source.

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.

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.

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).
