Poly aluminium chloride (PAC) alternatives - alumichem.com

Historically, acidic metal salt coagulants, such as poly aluminium chloride (PAC) or ferric chloride (FeCl3) has been the flocculants of choice for many wastewater treatment facilities. PAC offers a performance per price ratio, with better 20% Phosphor removal, lower chemical dosing and thereby also lower sludge amounts compared to ferric chloride.

Preparation of Poly Aluminum-Ferric Chloride (PAFC) Coagulant

Poly aluminum-ferric Chloride (PAFC) is a new type of high efficiency coagulant. In this study, high iron type gangue is used as a main raw material. It is calcined at 675 ¡ãC for 1 h and 3% CaF 2 is added to the calcined powder and reacted with 20% hydrochloric acid at 93 ¡ãC for 4 h. The leaching ratio of aluminum ions is 90% and that of iron

AN OPERATOR¡¯S GUIDE TO WATER TREATMENT COAGULANTS

To calculate the dose of a coagulant or other chemical in mg/L, you will need to know its % w/w strength and specific gravity. The formula is: mg/L = 10,000 X % w/w X SG. For example, consider alum at 49 % w/w strength aluminium sulphate (as Al2(SO4)3.18H2O) and with a SG of 1.29.

A comparative study of different coagulants used in treatment

The three types of different coagulants that have been employed are aluminum sulfate (alum), ferric chloride, and poly aluminum chloride (PACl). The samples are taken from the Tigris River at various levels from the water¡¯s surface (60, 120, 180, 240, and 300 cm).

Alternative cost-effective preparation method of

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

Preparation and performance of a high purity poly-aluminum

Considerable interest and attention have been paid in last three decades [1], [2], [3], [4] to prepare pre-hydrolysed metal-ion coagulants, based on either aluminium (e.g., poly-aluminium chloride) or ferric iron (e.g., polyferric sulfate).

Effect of silicon content on preparation and coagulation

Poly-aluminum-ferric-silicate-chloride (PAFSiC) showed better performance in terms of bio-refractory organics removal and floc characteristics than PSiCs with individual cations, owing to the synergetic effects of aluminum and iron based poly-silicic salts [13].
