Biqing water free samples, technical support, Tracking service, your satisfaction, my pleasure ......... 1, floc size: floc is too small will affect the drainage rate, floc floc constraints make much more water and reduce the mud biscuits. After selecting the molecular weight polyacrylamide can adjust the size of floc. 2, sludge characteristics: The first point to understand the source of sludge characteristics and composition, proportion. Depending on the nature of the different sludge can be divided into two kinds of organic and inorganic sludge. CPAM for disposal of biosolids, the relative anionic polyacrylamide flocculant for mineral sludge, strong alkaline when cationic polyacrylamide, anionic polyacrylamide and should not be used when very acidic, solid content high amount of sludge is usually polyacrylamide is also large. 3, floc strength: floc under shear should insist on steady without breaking. Advances in molecular weight polyacrylamide or select the appropriate molecular structure to help improve floc stability. 4, the degree of ionic polyacrylamide: for dewatered sludge, flocculant available ions of different small test do first through the selection, select the best suitable polyacrylamide flocculant thus being able to obtain the best effect, but also make dosage minimal cost savings. 5, dissolved polyacrylamide: Good to be fully dissolved flocculation. Sometimes it needs to speed up the dissolution rate, when the concentration of progress can think of polyacrylamide solutions. PAM and PAC can actually use it when the usual treatment of sewage, some water, a flocculant is not up to a single effect, you must use the two in combination, and in the use of inorganic flocculants PAC polyacrylamide flocculant sewage treatment complex will achieve better results, but the time to add agents to pay attention to the order, the order is not correct, but also fail to effect a sequential approach polyacrylamide flocculant used in combination with other added: In use Care must be taken when the composite flocculant adding sequence and dosing intervals! PAC and PAM is to allow PAC to be used in combination and after completion of the charge / colloidal stability formation of small floc, and further increase the floc size, which facilitates ample precipitation. Because PAC PAC response time is very short, so the added need intensive mixing, PAM longer duration of action, mixed note after the first strong weak - the first strong to weak after mixing in order to avoid destruction of floc! Polyacrylamide flocculant belong, belong PAC coagulant, under normal circumstances is to add coagulant together with polyacrylamide, but to be safe, it is recommended that you add by experimental results to determine the order! Dosing point, dosing quantity, dosing and mixing intensity required time determined experimentally, remember do not put them two agents used together, otherwise it will affect the results, increasing the cost.
