Different methods of using water treatment agents Different methods of using water treatment agents are different, filter water purification materials plant according to the types of agents combined with the experience summarized as follows for the study, the use of special water treatment agents can consult our technology. Polyacrylamide to use: (for a variety of chemical, printing and dyeing, municipal wastewater, etc.) 1, dubbed 0.1-0.3% concentration of the aqueous solution, stirring to dissolve neutral salt water is appropriate (such as tap water). 2, the product should be noted in the dissolution, especially the automatic dosing device flow rate is not too fast to prevent polyacrylamide caking, fisheye phenomenon, to prevent clogging the pipeline as unnecessary trouble. 3, stirring speed is generally 200-400 rev / min is appropriate, time is not less than one hour, appropriate to raise the water temperature 20-30 degrees Celsius, can accelerate the dissolution. Liquid temperature should be less than 60 degrees. 4, Because this product is suitable for a wide range of water PH value, the general dosage is 0.1-10ppm (0.1-10mg / L) or adjust the amount added according to the on-site water quality. Paint mist coagulant use: (professional in the paint sewage treatment agent) 1, in the painting operation, the general morning paint Additive A coagulant mist, and then the normal spray paint, half an hour before going to get off work to add paint mist coagulant agent B . 2, paint mist coagulant agent A dosing point in the circulating water inlet, B dosing point in the circulating water outlet. 3, according to the amount of spray paint and the size of the circulating water, timely adjustment paint mist coagulant A agent, B dose. 4, regularly measured twice a day the PH value of circulating water to keep it between 7.5-8.5, in order to make the best drug effects. 5, when the circulating water is used for a period of time, because the conductivity, SS value, suspended solids content of circulating water exceeds a certain value, it will make the paint remover can not be properly dissolved in circulating water, affect the use effect of paint fog coagulant, It is recommended to thoroughly clean the sink and replace the circulating water before use. The water change cycle depends on the type of paint, the amount of spray applied, the climate and the specific conditions of the painting equipment. Please follow the technician's advice on site. Polyaluminum chloride Usage: (for a variety of chemical, printing and dyeing, municipal wastewater, etc.) 1, the solid polyaluminum chloride product by 1:10 dissolved in water to stir into a liquid can be added to use. 2, the amount of raw water according to the different turbidity, the determination of the best dosage, the general water turbidity at 100-500mg / L, the dosage of 10-20kg per thousand tons. 3, high turbidity of raw water, dosage appropriate increase, low turbidity, dosage can be reduced appropriately. 4, polyaluminum chloride and polyacrylamide (anionic, cationic, non-ionic) with the use, the better. Calcium chloride Usage: (dry, ion exchange, etc.) 1, can be directly added to use. 2, or with water in accordance with the ratio of 1: 5 dissolved before use. Decolorization flocculant Usage: (Chroma wastewater) 1, with the beaker to take the right amount of wastewater (about 500ml), adjust the PH value to about 8; 2, the required dilution of reagents, decolorization flocculant diluted 10-50 times the dilution concentration; 3, under normal circumstances, bleaching flocculant with aluminum chloride, polyacrylamide PAM with the use of; 4, add the order, first add decolorizing flocculant, stirring, together with aluminum, stirring, and finally add PAM, 5, observe the color of the supernatant to meet the requirements, if not satisfied, adjust the dose dosing, repeat the fourth step; 6, according to the experimental data to calculate the amount of decolorizing flocculant and other agents per ton of wastewater. Paper additives to use: 1, the paper additives formulated as 0.1% concentration solution. One kilogram of medicament evenly thrown into a ton of water, pay attention to the side while stirring into the dissolve 1 hour after 40 mesh sieve dubbed dilute solution spare. 2, generally at the high box dosing, for filling the sizing paper, can also be equipped with pulp pool to join. 3, the amount of tons of paper is about 700-1000ppm, but according to the paper produced by different addition amount is also different. The addition of retention aid will greatly increase the retention of fillers and fibers, generally can increase about 25%.
