Along with the high speed industrial development,it raises pollution with entironment,especially with the water of life.since a great deal of industrial waste water flow into rivers and lakes,the acid rain and rain with a lot of harmful industrial materials enter into underground,the surface water and underground water are badly polluted.all these plus the large quantity of mud and sand in the rivers and lakes during raining seasons raise problems fro the living water of the mankind.these problems have already threatened the health of people.therefore,it has become the most important and urgent issue to manage the water resource and to decontaminate water effectively.many scientific research academies and manufacturers of tap water have developed high efficient and safe polymeric alumin chloride water-purifying agent so far,which were using on decontaminate the potable water and obtained good effect.

Our company produce the calcium aluminate powder,which is the chief and ideal parent materials of polymeric aluminum chloride.we are willing to contribute all our efforts to supply calcium aluminate powder of high quality for the purpose of raising the quality of living water and consequently guarantee people's health.

Polymeric aluminum chloride is a new of macromolecule flocculant,that is high efficiency water-purifying agent,which is made by reacting hydrated alumina with hydrochloric acid as the following chemical reaction formula:2Al(OH) 3 +nHCl=>Al 2 (OH) n Cl 6-n +nH 2 Othe,PAC acts as a coagulant to remove suspended particles,harmful materials and some metals(such as Cr,Ba,Cu)from water and therefore clear water can be obtained.this water can be used for industrial and can be used as portable water after disinfection.it is usually used for treating waste water stream by wastewater reatment plants,after disinfection the potable water can be obtained from water plants.

It needs very strict control of the alumina chemical composition of the materials to produce PAC.Calcium aluminate powder supplied by Orinet mineral inc is of high alumina content,better solubility,speed hydration,perfect filtration properties and low price.
