Polyaluminium chloride (PAC) dosing | PWTAG Technical Notes

For a pool with a capacity of 450m 3 (100,000 gallons) and a turnover period of 2 hours the circulation rate is 225m 3 per hour. The PAC dosing rate for this pool would be 22.5ml per hour. This is a very small quantity (two and a quarter 10ml test tubes per hour) and is difficult to dose accurately.

1. Introduction. Coagulation is a basic and essential water/wastewater treatment technique. It aggregates the small suspended and colloidal particles in the water to become bigger ones after coagulant is added, and the aggregated particles are easily removed by gravity settlement or filtration (Alexander et al., 2012, Verma et al., 2012).

polyaluminium chloride (PACl) have less impact than alum. Organic coagulants do not affect the raw water alkalinity and pH GEBBS¡¯ RULE 4 all coagulants produce sludge in the form of the metal hydroxide together with the coloured and colloidal matter that is removed from the raw water. But again, not all inorganic coagulants behave in the same

OH ? is the basic component influencing the morphology of polyaluminium chloride [6¨C9] whose index in PAC is measured by basicity (B). According to GB 15892-2003 (water treatment chemical-polyaluminium chloride) , basicity can be measured. The mol percentage of OH and Al in PAC is defined as basicity and this parameter can reflect the

Alternative cost-effective preparation method

An alternative preparation procedure for polyaluminium chloride (PAC), a common inorganic coagulant, is presented in this paper. The proposed procedure is based on the use of granular aluminium metal, a common by-product of several aluminium-processing secondary industries, instead of using Al 2 O 3 (or of using a mineral containing Al 2 O 3) which is commonly applied by most industrial
