Shanxi coal mine waste water treatment supplier --- PAC BK Gongyi City Water Treatment Chemicals Factory Official website http://www.bkscl.com http://www.bkjsj.com With the development of society, science and technology progress, environmental protection department of the wastewater discharge standards are increasingly demanding wastewater treatment water treatment chemicals used in the case of PAC products most widely used. BK Gongyi City water treatment chemicals plant in Shanxi coal mine wastewater treatment by PAC divided into two forms: namely: a, liquid PAC is not dry form, there is no dilution, handling ease of use, price relatively cheap advantages, disadvantages tanker transport needs, increase in unit transportation costs (equivalent to 2-3 tons per ton of solid liquid), more suitable for the user within 100 kilometers. b, solid liquid PAC PAC The dried form, has the advantages of convenient transportation, no tankers, the disadvantage is also needed to use dilution, increased work intensity according to the production process is divided into three types, namely:. a, drum-type poly (co) aluminum chloride aluminum content In general, water insoluble high, and more for sewage treatment. b, frame-poly (co) high aluminum content of aluminum chloride, water insoluble low, treatment for wastewater treatment and drinking. c, spray drying poly (co) high aluminum content of aluminum chloride, water insoluble low dissolution speed. higher standards for drinking water and water treatment. BK brand in Shanxi coal mine wastewater treatment with PAC commonly used spray drying production technology. BK brand PAC due to the spray drying, good stability, wide adaptation waters, hydrolysis speed, strong adsorption capacity, the formation of alum large, dense mass rapid sedimentation, turbidity is low, good dewatering performance, etc., in the same water quality Under the circumstances, spray drying PAC dosage reduction, especially in the case of poor water quality, spray-dried product sill flower basket crane dosage compared with drum drying poly aluminum chloride, can be reduced by half, not only reduced labor intensity, but more important is to reduce the cost of water users. In addition, spray drying PAC can ensure the safety of products, reduce water accidents, very safe and reliable drinking water to residents. PAC, referred efficient poly aluminum chloride, or efficient PAC. Using the most advanced production technology, using high quality raw material degree polymerization reaction. BK all quality indicators are met or exceeded the national standard GB15892-2009 requirements. Poly aluminum chloride is processed by spray drying process it can also be called efficient Spray drying poly aluminum chloride PAC PAC Product Features: PAC PAC BK brand products with powder fine, uniform particles, Soluble in water, good flocculation, clean efficient and stable, low dosage, and low cost. Suitable for drinking water purification, urban and industrial water purification water purification and other aspects; for a variety of source water turbidity, PH wide scope, alum formation of large, fast, fast settling velocity. PAC PAC concentration ratio: According to the daily use of solid PAC PAC, diluted liquid, summarize share several common PAC PAC concentration ratio method, we want to help! The first step, according to the situation of raw water, prior to use do first small test and determine the optimal dose. Small test solution configure a weight ratio (W / W), generally 2 to 5% of the distribution as well. If equipped with a 3% solution: PAC PAC solid 3g, poured into a 200ml graduated cylinder, add water about 50ml, add water to be dissolved diluted to 100ml mark, shake can. The second step, the production of PAC PAC, press PAC PAC solid: water = 1: 9 to 1:15 weight ratio dissolved. Alumina content of less than 1% of the solution is easy to hydrolysis, will reduce the use of effects, the concentration is too high is not easy dosing evenly. The third step, the optimal dosing according to the amount of investment plus a small test obtained dosing. See, for example alum less sedimentation, turbidity than large, the dosage is too small; see, for example alum large settling ponds and on the turn, I turbidity is high, excessive dosing should be adjusted appropriately. PAC Features: 1, floc forming fast, good activity, good filtration. 2, without additional alkaline additives, such as the case of deliquescence, the effect is the same. 3, PH value width adaptation, adaptable and versatile. 4, the treated low salinity water. 5, can remove heavy metals and radioactive substances to water pollution. 6, the active ingredient is high, easy to store and transport. PAC packaging and precautions ⒈ external plastic bags, plastic film inside the suit, net weight 25kg, can be modified according to user requirements, and another liquid PAC sales. ⒉ the goods prohibited mixed with toxic substances, transport and storage, the product should be stored indoors in a dry, ventilated, cool place, do not place damp. ⒊ Handle with care when handling, solid product storage period of one year.
