The new life of traditional water treatment flocculant
Polyaluminum chloride (Al2Cln(OH)6 n, PAC) is currently the most commonly used occulant for water treatment in indus- trial production, with its usage reaching up to 3000–4000 tons per day.1–5 It has been reported that polyaluminum chloride can exist in three different forms in aqueous solutions: monomer (Ala), fast reaction colloid (Alb) and s...

Saudi Arabia 28%-30% Polyaluminum Chloride Advanced for Water
Polyaluminum Chloride (PAC) is one of the most efficient water treatment chemicals utilized today. It is widely used in both potable water and wastewater treatment because it provides high coagulation efficiency and it has the widest pH and temperature application ranges compared to other water treatment chemicals.

Application progress of enhanced coagulation in water treatment
1. Introduction Coagulation is one of the most common phenomena in nature and artificially enhanced water treatment systems. Coagulation is a process in which small particles are combined into larger aggregates (flocs) and dissolved organic matter is adsorbed onto particulate aggregates so that these impurities can be removed in the subsequent solid/liquid separation processes. 1 The mechanism

Preparation and Characteristics of Polyaluminium Chloride by
Clay-brine process employing activated clay, NaCl, HCl, and HF as raw materials is the primarily advanced technology to synthesize cryolite in the present industrial grade. However, plenty of byproducts of fluorine-containing waste HCl at the concentration of about 10%~12% could not be utilized comprehensively and are even hazardous to the environment. This work proposed a new

POLYALUMINIUM CHLORIDE | Ataman Kimya A.Ş.
Polyaluminium Chloride (PAC) is used as a flocculent in water treatment applications including drinking water and wastewater treatment. PAC can perform over a wide pH range (5.0 – 8.0) but is most effective when the pH is close to 7.0, this can be achieved with the use of Soda Ash (Sodium Carbonate) or Sodium Bicarbonate.
