Polyaluminum chloride (PAC)
Product Description
Polyaluminum chloride (PAC) is an efficient coagulant widely used in wastewater treatment, water purification, and industrial circulating water treatment.
Polymeric Aluminum Chloride (PAC) is an inorganic polymer flocculant featuring fast flocculation, good sedimentation effect, and wide applicability.
It is mainly used for the purification of municipal sewage, industrial wastewater, drinking water, paper-making and printing wastewater. Through adsorption, bridging and charge neutralization, it quickly aggregates suspended solids, colloids, chroma and pollutants in water to achieve solid-liquid separation and clear water quality.
2. Main features and functions
Flocculation and sedimentation are fast, forming large flocs with fast settling speed and significant solid-liquid separation effect.
Strong purification ability, capable of effectively removing turbidity, chromaticity COD、 Suspended solids and some heavy metals.
Widely used in wastewater treatment for drinking water, municipal sewage, papermaking, printing and dyeing, chemical industry, mining and other industries.
Widely adaptable to pH, stable operation within the pH range of 4-12.
Low dosage and cost, more economical than traditional drugs.
Low corrosiveness, safe for equipment and pipelines.
