PRODUCT FOR THE TREATMENT OF WATER AND WASTEWATER AND A PROCESS FOR PRODUCING SAID PRODUCT |
摘要 |
<p>The present invention relates to a product for the treatment of water and wastewater and a process for producing said product. Said product comprises high cationic starch powder and a brine solution comprising sea water and/or salts comprising two-valent ions. The salts are preferably CaCl2 and/or Ca(N03)2 and/or MgCl2. The concentration of the brine solution is 5 - 50 g/l, preferably 10 - 40 g/l. The starch is preferably potato starch and has > 10 % charge density (degree of substitution). The starch concentration is 5 - 25 weight %, preferably 15 - 25 weight %. The viscosity is 300 - 10000 cP (mPa s), preferably 1000 - 5000 cP (mPa s). The product for the treatment of water and wastewater is produced by feeding a high cationic starch powder gradually into a brine solution using a high shear mixer.</p> |
