Get PriceIs polyaluminium chloride better than polyelectrolyte – alum-based coagulation?
At the Barekese Water Treatment Plant in Ghana, an alternative, the polyelectrolyte – polyaluminium chloride (PAC) is also used in coagulation but limited information is available on the operating conditions required to achieve better performance than alum-based coagulation.
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 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 chemical coagulation in water treatment plant?
A common step in most of water treatment plants is the chemical coagulation. The chemical coagulation is the process of destabilizing the colloidal particles suspended in raw water by the addition of coagulants. Generally, the determination of the quantity of coagulant to be added to water is made manually by jar tests.
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.
