Poly Aluminium Ferric Chloride Sulphate (PAFCS)
PAFCS is a new product of high-efficient water purifying agent invented in recent years, which polymerizes a proper amount of PFC and introduce an appropriate amount of synergistic agent SO42-, based on the high-efficient water purifying agent PAC. This product is composed of inorganic polymer PFS and PAC. The chemical general formula is:
[AL2(OH)nCl6-N-2K(SO4)K]mf±X[Fe2(OH)nCl6-N-2K(SO4)K]m, (PAFCS for short).This products converged the merits of the fªAlfª and fªFefª all in one ,the merits including the high effective content, high saltness, large polymerization, high condensity of molecular chain network and large constructure. This product has far stronger adsorptive and cohesive power and better purifying effect in purification. It is a high-efficient, fast, low-conswne, innoxious and safe inorganic high-efficient water purifying agent. It makes full use of the compensation of ferric ion and succeeds in getting rid of the harm which ion Al3+ remaining in water does to human.
Compared with traditional PAC(S), ALSO4(L), PAS(L), PFS, PFC and so on, the use amount of PAFCS can be greatly reduced and the cost is very low. This product can reach the purification standards while other agents can not resolve, especially some difficult problems of water treatment such as lowering heavy cloudiness and de-coloring.
It can be widely applied in to comprehensive treatment of urban sewage by strengthened first-stage treatment process. The quality of the treated water can reach the first-level discharge standard. The removal efficiency of total "Phosphorus" is very high and the eutrophication of the water can be controlled.
In contrast with the second-stage biological treatment technology, this technology can reduce not only investment of the capital construction, but also the operation cost. So it is a very practical and efficient technology for water treatment.
PAFCS has the ability of both inorganic coagulation and high-efficient capture and cure of polymer coagulating agent. In contrast with the traditional water purifying agents such as aluminium salt and ferric salt, PAFCS can improve the treat efficiency, decrease the cost of water treatment and can improve the water quality

Application method, storage, packing and transport of product
You should add 3-4 times water first and mix it so as to make it dissolve, then add directly and quickly or add water to make it diluted so that suits the consistency you need (3~10 NTU is proper for desaturation solution consistency. Store time of diluted solution usually doesnf+t exceed 24 hours).
According to the fixed proportion, add it into primary water or sewage, let it flow together with water and stirs naturally to precipitate.
The proportion of using the product is decided by turbidity and water quality. They are as follows:
Turbidity ( NTU ) Adding proportion ( KG / KT water)
15 2
100 9
500 16
800 25
2000 35
Application notice of PAFCS:
1) Solid products adopt brown paper or woven bag, inside lining with plastic packing; net weight 25kg;
1) The products should store in dry and ventilater place;
3) When being transported, should avoid being mixed with harmful and poisonous goods.
Poly ferric sulphate
Appearance: Light yellow amorphous solid. The product quality meets the China National Standard<> (GB14591-93). Methods of operation and point for attention. As the property of raw water is different, experiment for the optimum dosage and conditions previous to operation is necessary so as to obtain the best effect.
1. Determination of the consistency. Before using, dissolve the product in running water in the proportion of 10-30 so as to make it hydrolyze completely. Laying it to present red brown solution, then dilute it to the consistency required for coagulation. It is usually diluted to the consistency of 2-5 in waterworks, and 5-10 in the industry waste water
2. Determination of the optimum dosage. In view of the different property of raw water, it can be determined by the experiment. For the waterworks, you may refer the dosage of other flocculant operated before. Under the same conditions, its dosage is almost equal to the Polymer Aluminium Chloride, 1/3-1/4 of the solid Aluminium sulphate. For the liquids product, you may calculate its dosage according to its consistency.
3. Pump the medicament compounded into the measure trough. When operated, add it into the raw water to coagulate with the raw water
4. It is usually compounded when operated in the running water. It is normal to have a little precipitate in it.
Pay attention to the waterpower condition and the state of alum flower in the course of coagulation; Coacervation stage: The medicament flows into the coagulation pool, where it coagulates rapidly with the raw water and forms tiny alum flowers within very short time, at the same time, the water becomes even more turbid. A sharp rushing water is necessary in this stage. For the beaker test, mix for 10-30S in the speed of 250-300r/min, normally not exceed 2 mins. Flocculation stage: It is a process that tiny alum flowers grow longer and bigger. It is necessary for the water to have a suitable rushing water and sufficient velention period (10-15mins). In the later period of this stage, a large quantity of alum flowers gather and subside slowly. For the beaker test, mix for 6 mins in the speed of 150-200min, then 60r/min for 4 mins, to present a suspended state. Subsidence stage: It is a process that the flocculate subsides in the subsidence tank, where a slow current velocity is necessary. To improve the water quality, the subsidence tanks are usually designed in the oblique tube or oblique board model, (it is best to separate the flocculate by the fªgas-floating) method), so that a large quantity of thick alum flowers are stopped by the tube or board wall and subside at the bottom of the tank. The upper layer is clear liquor. In the meantime, the alum flowers with small size and density subside slowly and continue colliding to grow large. In the later period, the turbidity id almost fixed. For the breaker test, mix for 5 mins in the speed of 20-30 r/min ,then subside for 10mins and check the turbidity .
6. Strengthen the filtering: Choosing the reasonable filtering layer structure and filtration aid, is the important measure to improve the water quality.
7. For the treatment of industry waste water , on the whole it is similar to the waterworks. Cooperated with other coagulant aid, it will achive a optimum effect in the treatment of raw water with high colour, COD and BOD.
8. For the factories and mines employing the chemical coagulation method, the product can also be used by adding a dissolving pool only.
9. The product can be preserved in the place for a long time, where is dry, damproof and heatproof(normally below 80 f¦).And be sure not to damage the package.
10. The product must be dissolved before use . Further, the equipment for dissolution and feeding should be anti-corrosive.

Water treatment chemicals refer to a diverse group of substances used to improve the quality of water for various purposes. These chemicals encompass a wide range of applications, from disinfection with chlorine or ozone to remove harmful microorganisms, to coagulants and flocculants like alum and polymer additives that aid in the removal of suspended particles in wastewater treatment. pH-adjusting chemicals like lime and sodium hydroxide help balance the acidity or alkalinity of water, while corrosion inhibitors protect pipes and equipment. Additionally, scale inhibitors, activated carbon, and ion exchange resins are used to remove impurities and pollutants. Water treatment chemicals play a vital role in ensuring safe, clean, and potable water for consumption, industrial processes, and environmental protection.
