English name: PAFC
Appearance: liquid product is brown or red-brown transparent body, no precipitation. The solid product is brown, reddish brown powder or granular.
PAFC is a new type of complex amorphous, inorganic polymer water purifier priority to aluminum,supplemented by iron. Iron is high-priced iron, format multi-nuclear complex after hydrolysis. When in low temperature, PAFC has the characters of alum flower specific gravity large and close forming in the water. This is mainly because hydrolysis rate of ferric salt is affected by the temperature a little. As the less iron content, do not reduce the PH value of water to much and increase the color of water. On the contrary, due to the removing color performance of aluminum salt, the color of the water is greatly reduced. So have the characteristics of PAC and iron salts. overcome the purification difficulties of the PAC in the low temperature and low turbidity water. Therefore, the water purification effect is better than the general water purification products. The product is developed on the basis of in-depth research in the poly aluminum chloride and iron oxide, it has the advantages of aluminum and iron salt coagulant hydrolysis and coagulation mechanism, has significantly improved on aluminum and iron ions formation, the degree of polymerization is also greatly improved.

Iron oxide desulfurizer is a brown Huang Sezhu solid desulfurizing agent, mainly composed of ferric oxide refined but become, have without oxygen existing desulfurization.Its principle is to contain sulfur compounds in waste gas chemical adsorption into the holes of desulfurizer, change its chemical composition and purifying gas.As desulfurizer reaches saturation, namely its desulfurization ability no longer need to regenerate, the regeneration of using water vapor to stripping.Ferric oxide desulfurizer, however, after using for a long time, its activity will continue to decline, as the holes is obstructed by some impurity content, desulfurizer is disabled at this moment, but when when there are trace oxygen reaction system can improve the desulfurization activity, prolong service life.The waste desulfurizer can be recycled, the active ingredient.
Iron oxide desulfurizer in use has some advantages such as simple equipment, convenient operation, high degree of purification, small bed layer resistance, strong adaptability, fast desulfurization, the characteristics of high sulfur capacity, no secondary pollution, even under harsh conditions, such as in anaerobic ammonia, can also be high precision removal of hydrogen sulfide.
Ion exchange resin is with functional groups (exchangeable ion active groups), with a network structure, insoluble polymer compounds, usually it is spherical particles, it can exchange its own ions and the same number of ions in solution. Depending on the nature of the exchange group, ion exchange resin can be divided into two types of cation exchange resin and anion exchange resin. Commonly used ion exchange equipment filled with ion exchange resin are mostly 201*7 strong styryl anion exchange resin and 001*7 strong acidic styrene cation exchange resin. If the water quality is particularly high in the occasion we always use polished ion exchange resin.
Working principle of ion exchange resin
Water softening: Under normal circumstances, the conventional sodium ion exchange resin with a large number of sodium ions. When the water content of calcium and magnesium ions is high, the ion exchange resin can release sodium ions, functional groups and calcium and magnesium ions, so that the water content of calcium and magnesium ions decreased water hardness decreased. Hard water becomes soft water, which is softened water equipment work process.
Regeneration: When the ion exchange resin on a large number of functional groups combined with calcium and magnesium ions, the ion exchange resin softening capacity can be used sodium chloride solution flow through the ion exchange resin,at this time with the high sodium content, Functional groups will release calcium and magnesium ions and sodium ions, so that ion exchange resin can restore the exchange capacity, this process is called regeneration.
Anthracite coal is the largest degree of coal, the general carbon content of more than 90%, volatile matter below 10%, has high density, hardness and ignition, burning with no smoke.
