Fourth, the PAC to use environmentally friendly production of Hubei Spirit: first the product is dissolved into a solution of 10% -30%, and then diluted with water to the desired concentration. Optimal dosing PH value 3.5-5.0, PH value to select the best dosage, can maximize the effectiveness of coagulation. General turbid water per 100 tons pharmaceutical dosing 0.5-2.0kg (5 - 20ppm) polymeric silicate iron prices, raw water turbidity is high, the dosage appropriately increased turbidity low iron silicate, the dosage may be appropriate to reduce . Rural use, put the medicine in the tank, stir polymeric silicate iron prices, standing, the supernatant can be used to join wood Pharmacy l per 50 kg grams. Will be combined with the use of such agents and I produced a polymer flocculant, the better. Dosing can be produced by our company or anionic polyacrylamide with cationic polyacrylamide flocculant PAC dissolved together into a composite PAC after first use or adding water to be treated wastewater formed aggregates iron silicate, after joining the company anion polyacrylamide adsorption bridging larger floc. Third, use: 1. Widely used in the oil industry oily wastewater treatment, water separator, oil field injection water of purification. 2. It is ideal for the pharmaceutical industry wastewater, wastewater treatment, and is widely used in metallurgy, electric power, leather, pharmaceutical, printing and dyeing, chemical and other industries. 3. It is ideal for drug treatment of high fluoride water, fluoride works well, is an important chemical raw materials. Use in chemical, foundry, cement, refractories and other aspects.
