Polymerized aluminum ferric silicate (PSAF) is a major reform of the pharmaceutical
Polysilicate aluminum iron (PSAF) is a new type of water-soluble polymer electrolyte. Mainly used for drinking water purification, can also be used for special water quality treatment, cadmium removal, removal of fluorine, removal of radioactive pollution, removal of oil slick, etc. Also used for industrial wastewater treatment, such as printing and dyeing wastewater, also widely used in casting, papermaking, textile, leather, etc. In the field of sewage treatment of sewage treatment has an immediate effect, is currently very popular sewage treatment agent.
Polyaluminum chloride has strong bridging and adsorption properties. In the process of hydrolysis, condensation, adsorption, precipitation and other physical and chemical processes will occur.
Polyaluminum silicate has the characteristics of high ionic property, easy to dissolve in water (completely soluble in water in the whole PH range, not affected by low water temperature), no gelling, hydrolysis stability. The positive charge density on the macromolecular chain is high, the product is water-soluble, the molecular weight is moderate, so it has the dual performance of flocculation and disinfection. Compared with the traditional inorganic flocculants (such as polyaluminum chloride, aluminum sulfate, basic aluminum chloride, etc.), flocculants have the characteristics of less sludge production, fast settling speed, good water quality and low cost. A new process of direct filtration can be used, which is undoubtedly a major reform of traditional water treatment.
The drug commonly used in the industry production line is polyacrylamide. Polyacrylamide is a water-soluble polymer. Solid polyacrylamide must be dissolved in tap water to form a gelatinous liquid before use. Configuration of solid polyacrylamide process is actually polyacrylamide maturation process polyacrylamide anion, so that the molecular chain expansion, play its strong cohesion.
Flocculants can not only effectively reduce the solid content of suspended solids in water, thus reducing the turbidity of water, but also precipitate viruses and reduce the action of precursors of trihalomethane in water, thus reducing the total carbon content (TOC) in water. Flocculant can be used as the main flocculant and coagulant aid (dosage of 0.5-0.7PPM equivalent to 50~50~50% alum), the clarification effect on water is more significant. In particular, the treatment of low turbidness water is beyond the reach of other types of polymer flocculants.
The action and use of polymerized aluminum iron silicate:
Polyferric aluminosilicate flocculant is a water-soluble inorganic polymer compound. It has a high cationic charge, soluble in water and poor storage stability. Suitable for the treatment of low turbidity and low temperature wastewater. Polyacrylamide anion may be used alone or in combination with aluminum sulfate or basic aluminum chloride.
Polyacrylamide is a particularly good water treatment agent, and non-toxic, will not cause much harm to water quality. The amount of cationic polyacrylamide needs to be properly controlled. If the amount of cationic polyacrylamide is too much, it will reduce the consequences of polyacrylamide. The cationic polyacrylamide used in water treatment, petroleum exploration, paper making, printing and dyeing industries, according to the needs of various industries, the first polyacrylamide dissolved into liquid.
In domestic sewage treatment, polyacrylamide can promote the rapid aggregation and precipitation of suspended particles through electric neutralization and its own adsorption bridging effect, to achieve the effect of separation and clarification. It is mainly used for flocculation and sedimentation in the front section of sewage treatment plant and dehydration of sludge in the back section.
Compared with other water treatment agents widely used in the market at present, such as: polyaluminum chloride, basic aluminum chloride, polyaluminum ferric chloride, etc., it has the characteristics of less sludge discharge, quick settlement, good effect and so on. Good water quality and low use cost. And can effectively reduce the solid content of suspended solids in water, reduce the turbidity of sewage, the clarification effect of sewage is significant. In particular, the treatment of non-ionic polyacrylamide in low turbidity water is incomparable to polymeric flocculants such as polyaluminum chloride and basic aluminum chloride.
