Dilute the water to the desired concentration and add coagulation. Water plants can also be dubbed 2-5% direct dosing, static to a red-brown liquid. In fact, to determine the amount of PAC PAC dosage is very simple, as long as we use PAC PAC to vote with the method used basically will not go wrong. 1 according to different situations. 2; 3-1 & # 47. If the original is a liquid product, according to the corresponding drug concentration calculation discretion. Approximately by weight ratio of 1: 3. 3, when used, the above prepared good liquid medicine, pumped into the metering tank, dosing liquid by measuring and coagulation of raw water. 4, under normal circumstances the day of the preparation of the day use, dispensing need tap water, a slight precipitate is a normal phenomenon, dosage to determine the nature of the raw water through the production commissioning or beaker experiment as alum to form the appropriate amount, the water plant can The original amount of other drugs used as a reference, under the same conditions, the amount of the product and the solid PAC is roughly the same amount of solid aluminum sulfate 1 & # 47, before use, good PACI products to play its The best effect, the rational use of the method is essential, the injection of tap water to fully hydrolyze the hydrolysis, the PAC will be a certain concentration (10-30%) into the solvent pool; 4, industrial waste water directly 5-10% dosing, on-site commissioning or beaker test, to obtain the best conditions for use and the best dosage to achieve the best results
