Polyaluminum Chloride (PAC) | GEO Specialty Chemicals
At the top of the scale is aluminum chlorhydrate (ACH): at 83%, it is the highest stable basicity PAC available. (ACH is simply a special species of PAC - more about ACH in the next section). PAC's can offer a number of advantages over
The coagulant used in the pilot plant, which was located in water treatment plant, was poly aluminum chloride. We used existing data, including the type and concentrations of coagulant, pH and influent turbidity, of the raw water because these

Poly Aluminium Chloride (PAC) - Water Treatment Chemical
Poly aluminium chloride (PAC) , the white or yellow powder, is an inorganic polymer coagulant. Compared with traditional inorganic coagulants, fengbai poly aluminum chloride flocculation precipitation speed is fast, the PH value applicable range
The modern use of coagulants for water treatment started more than 100 years ago, when ferric chloride and aluminum sulfate were used as coagulants in full-scale water treatment works. The coagulation mechanism was firstly explained by the
- Does pH affect the performance of polyaluminum chloride (PAC)?
- The performance of PAC was dependent on pH. The synthesized PΑC was efficient coagulant for water treatment. The present work was aimed to synthesis of polyaluminum chloride (PAC) using calcium oxide as a basification agent and optimization of process parameters on the yield of medium polymer species in PAC.
- What is polyaluminum chloride (PAC)?
- Polyaluminum chloride (PAC) is a classic inorganic polymer material, which has the advantages of easy preparation, low cost, and high efficiency in the field of water treatment and other areas of environmental protection [ 1, 2 ].
- Is polyaluminum chloride a good coagulant for water treatment?
- Polyaluminum chloride (PAC) is highly effective coagulant for water treatment over conventional coagulants because of low dosage requirement, shorter flocculation time, smaller amount of sludge, high efficiency and low aluminum residual in treated water [ 6 ].
- Is polyaluminum chloride a Lewis acid catalyst?
- Polyaluminum chloride (PAC) is an inorganic polymer material that has the advantages of a simple preparation process and special electronic structure. It is considered to be the most efficient and widely used flocculation material for water treatment. In this work, PAC has been used as a Lewis acid catalyst in inte
