| Message: | Electroplating factory wastewater treatment using polyacrylamideAccording to incomplete statistics, our country has 40 billion m3 effluent from electroplating factory every year. Because the great damage it causes to the environment and the non-degradableheavy-metal ion it contains, the effluent water from electroplating factories is payed highly attention by the government of every county. Boyuan company has devoted to effluent treatment for the electroplating industry for years, and developed several methods like chemical precipitation, electrolysis, ion exchange and membrane treatment method. Based on the national standard, the Cr~(6+) should be under 0.5 ppm, one of the regular way to remove Cr~(6+) is adding Ferrous ion for reduction reaction. The finnal result is ferrite, which is hard for natural sedimentation. So ,we put HPAM into the effluent to accelerate the sedimentation.The sedimentation are effective by the conditions of the Mol. Weight, DH, dose amount, the effluent PH and etc. We have develop a effective and low-cost method for electroplating factory effluent from thousands of tests and analysis.
