How to maximize the effect of polyaluminum chloride? For polyaluminum chloride customers, not to buy the best quality products on the line, but also in the use of various aspects of attention, in order to make PAC play the biggest effect, then all that need attention? 1, polyaluminum chloride according to the different conditions of raw water, before use, try to get the best dose. For ease of calculation, small test solution configuration weight by volume ratio (W / V), usually 2 ~ 5% with good. If with 3% solution: PAC3g, Sheng into the 200ml cylinder of clean, add water about 50ml, to be dissolved and then diluted with water to 100ml scale, shake well. 2, the production by solid: water = about 1: 5 first mixed dissolved, add water diluted to 2 ~ 3% (W / V) solution can be. Less than 1% solution is easy to hydrolyze, will reduce the use of effect, too high concentration can easily lead to waste. 3, polyaluminum chloride, according to the best dosage to be added. And pay attention to observe the adjustment in operation, such as see the settling pond alum less, Yuzhu big, the dosage is too small, see the precipitation of alum large and turn up, Yuzhuo high, the dosage is too large, it should be appropriate Adjustment. 4, dosing facilities should be anti-corrosion. Polyaluminium chloride is suitable for all water treatment facilities.
