Water treatment chemical ACH CAS NO:12042-91-0 for water treatment chemical

ALUMINUM CHLOROHYDRATE / ACH For Drinking Water Treatment:   1,Aluminum Chlorohydrate(ACH): Other name:ACH MF:Al2(OH)5Cl·2H2O CAS NO:12042-91-0 EINECS NO:234-933-1    2,Introduction: Aluminium chlorohydrate is a group of specific aluminium salts having the general formula AlnCl(3n-m)(OH)m. It is used in deodorants and antiperspirants and as a coagulant in water purification.   In water purification, this compound is preferred in some cases because of its high charge, which makes it more effective at destabilizing and removing suspended materials than other aluminium salts such as aluminium sulfate, aluminium chloride and various forms of polyaluminium chloride and polyaluminium chlorisulfate, in which the aluminium structure results in a lower net charge than aluminium chlorohydrate. Further, the high degree of neutralization of the HCl results in minimal impact on treated water pH when compared to other aluminium and iron salts     3,The advantage of ACH:   1),It is accepted as the replaced product of PAC (Polyaluminum Chloride) used for the water treatment ,to reach the same result when treating water.   2),It is less consume quantity than PAC, very friendly to environment .    3),It can lead to quick formation of flock with big size and rapid precipitation.   4),It has widerange adaptability to thewaters at different temperatures and a good solubility.   5),The solution of ACH is slightly corrosive and suitable for the automatic dosing and convenient for eperation.   4,Use and advantages:   1) Urban drinking water treatment   ACH is used as flocculant in municipal water,drinking water,domestic water treatment.    The product is produced by pure aluminum and high purity hydrochloric acid, This product conform to the requirements of USP34 Specifications, internationally recognized as drinking water treatment agent.   Switch to high aggregate of aluminium recognized benefits   - Improve turbidity removal capacity, improve flocculation speed.   - Enhance the TOC (total organic carbon) removal.   - Reduce turbidity filter, shorten the filter travel and improve production ability   - Improve eliminatethe fluorine in addition to cadmium in addition to radioactive    pollution in addition to floating oil ability.   - Reduce reagent use, Simplify the operation process, Eliminate pH value influence.    Don't add second electrolytes.   - Reduce tap water production cost.   2) The urban sewage and industrial wastewater treatment   - Increase decoloring function   - Clean up TSS (the total suspended solids)   - Remove heavy metals such as lead (Pb), cadmium (Cd) and mercury(Hg) chromium(Cr+6)   - Removal Phosphorus, Fluoride and oily in the suspended solids   - Reduce 50% of sludge   - Reduce reagent use, Simplify the operation process, Eliminate pH value influence.    Don't add second electrolytes.Reduce tap water production cost.   - Effectively reduce the COD, BOD,TOC white water   3) Paper industry   - Sizing agent (AKD) of the precipitation agent   - Size adhesive   - Anionic garbage removal agent   - Retention aid agent and filter aid agent   - It is additives for control Resin obstacles   4) Cosmetic Raw Materials   - Be used as the ingredient for pharmaceuticals and antiperspirant,and the special cosmetic in    diary chemical industry .   5,Package and storage:   Package:25kgs per bag. Storage:Stored in cool ,dry and ventilated place. Shelf time:2 years.       .
