Bio Additives Product Features: Set biochemistry, flocculation in one, mainly for aerobic biological treatment of sewage, water treatment chemicals to improve the procurement of microbial activity, improve processing efficiency, or for industrial sewage treatment works commissioning phase, in order to promote microbial acclimation training of water treatment chemicals, reduce cycle, or during operation biochemical improvement equal biological problems. Ferrous sulfate Features: green crystalline solid, purity of 90% or more. Decolorization ability, alum and more precipitation fast. After treatment before dyeing wastewater treatment ρ (coagulant) mg / L blue cloudy colorless liquid aluminum sulfate 300 PH 7.5 PH 6.8 PAM 20 COD 300mg / L COD 145mg / L PAC Guangzhou Fu students - how to use it The PAC was 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), water treatment chemicals selection criteria raw water turbidity is high, the dosage appropriately increased turbidity is low, the dosage of the drug can be reduced appropriately. The use of water treatment chemicals in rural areas offer can be put inside the tank Pharmacy, stir and let stand, 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 aggregates formed, after joining the company's anionic polyacrylamide adsorption bridging larger floc. Ningbo, water treatment chemicals, rich students, procurement of water treatment chemicals provided by the Guangzhou Environmental Protection Engineering Co., rich students.
