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.

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 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. […]

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.

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.
