CN102372299A - Preparation method of poly aluminum chloride in high purity
The invention provides a normal pressure novel process of preparing poly aluminum chloride in high purity with an n-step segmentation method, wherein, the process only needs industrial hydrochloric acid and calcium aluminate powder for water tre
The production of PAC is accomplished by the introduction of sodium aluminate solution into the basic aluminium chloride solution under stirring, resulting in a product that can be described with the generic formula Al n (OH) m Cl 3n−m (when HCl
Polyaluminium Chloride(PAC) water treatment agents for industry water, drinking water
Polyaluminium chloride (aluminium chlorohydrate) also simply called PAC, is used in deodorants and as a coagulant in water purification. This compound is preferred in some cases because of its high charge, which makes it more effective at
Superior quality treated water is also produced with respect to TDS, CCPP and SO 4. OBJECTIVES The vital objectives are to assess the efficacy of Poly aluminium chloride (PAC) over Alum in coagulation-flocculation process and to characterize the
USING POLYALUMINIUM COAGULANTS IN WATER TREATMENT
At one water treatment plant in the Otway region of Victoria, polyaluminium chloride replaced alum and in so doing SO 4 levels in the treated water were reduced from 27 to 4 - 5 mg/L. Previously, alum was dosed at 45 to 55 mg/L at this plant.

Poly Aluminium Chloride – pacwatertreatment
Poly aluminium Chloride (PAC) is high-efficient, cheap and nontoxic inorganic high molecular compound. The liquid is colorless or light yellow and transparent; the solid is light yellow powder. It is easily soluble in water. In the hydrolytic
Poly aluminium chloride (PAC) is an industry standard primary alumunium based coagulant used for the treatment of drinking water, sewage and industrial effluents and is also a well established paper processing aid. It is a highly charged polymer
- Is polyaluminum chloride a coagulant?
- Inorganic coagulants such as polyaluminum chloride (PAC) have been used for years to treat water and wastewater. However, PAC as a coagulant can harm the living environment as it is toxic to humans and aquatic ecosystems. The use of natural and biocompatible materials such as sodium alginate as coagulant-aid can reduce the use of PAC.
- Does polyaluminium chloride coagulant affect the structure and diversity of pollutants?
- The polyaluminium chloride (PAC) coagulant was applied to determine the impact of the treatment process on the structure and diversity of these pollutants in urban drinking water.
- Does polyaluminium chloride affect microbial community in urban river sediments?
- Polyaluminium chloride (PAC) has been widely used as a chemical coagulant in water treatment. However, little is known about the impact of PAC performance on the microbial community in sediments. In this study, the archaeal, bacterial, and fungal communities in urban river sediments with and without PAC treatment were investigated.
- Can polyaluminium chloride improve coagulation process in conventional water treatment?
- The coagulation process in conventional water treatment could be enhanced and the ensuing water pH decline reduced appreciably by applying the right dosage of polyaluminium chloride and appropriate process conditions of pH, fluid mixing speed matrix and residence time.
