A: Product Overview RS100 is independently developed by a new generation of polar Weak heavy metal chelating agent. Unlike traditional liquid recapture agent under RS100 room temperature for the white powder, the solution is a colorless liquid that can strongly bind to heavy metal ions (Cu2 +, Ni2 +, Hg2 +, Pb2 +, Cr3 +, Cd2 +, etc.), to generate water-insoluble non- harmful sludge. Even for heavy metal ion complexation state, RS100 has the same treatment effect, to ensure that the content of heavy metals in waste water below the national emission standards. II: Features RS100 using a unique synthesis process, the production cost compared to traditional heavy metal chelating agents are greatly reduced. Moreover, after the molecular structure of the system design level, the performance has a greater advantage: molecular polarity increases, increase the force of heavy metal ions, which have a stronger ability to chelate heavy metals; the charge distribution is more scientific, can self-assemble to form more complex bridging structures, and thus significantly improve flocculation. RS100 uses a unique synthesis process, the production cost compared to traditional heavy metal chelating agents are greatly reduced. Moreover, after the molecular structure of the system design level, the greater the advantages of performance side: the molecular polarity increases, and increase the force of heavy metal ions, which have a stronger ability to chelate heavy metals; the charge distribution is more scientific, can self-assemble to form more complex bridging structures, and thus significantly improve flocculation. Three: Advantages 1, with copper, for example, RS100 copper ion concentration can be reduced to 0.1ppm or less wastewater containing copper, but the amount of similar products in the market is only 1 / 2-1 / 5 (free state copper), for complex The amount of copper more obvious advantages. 2, no callback pH, reducing treatment process. 3, RS100 own non-toxic, does not produce hydrogen sulfide and other toxic substances in the course, it will not increase the use of excess wastewater COD; RS100 and chelate heavy metals at high temperatures (not higher than 250 ℃) and acid and alkali Under the conditions do not decompose, thus stabilizing treatment by RS100 heavy metals in soil does not produce secondary pollution. Four: The use of a complexing agent in wastewater composition is different, the optimum conditions are different RS100. Usually acid complexing agent a) adjusting the pH of the wastewater to 10 or more; 2) into a solution an amount of RS100, stirred 10min 3) into the same amount of PAC was stirred 5ml, 4) into PAM 5ml 0.1% per liter of solution, after stirring for 2min precipitation 30min; 5) the supernatant measured nickel content filtering; generally alkaline complexing a) to adjust water PH 3-42) put in a certain amount of RS100 solution, the reaction 10min 3) put in the same amount of PAC pullback to Stir pH6-7 4) into PAM 5ml 0.1% per liter of solution, stirring after precipitation 2min 30min; 5) the supernatant was measured nickel content filtering; five: Notes 1. Note that attempts to prevent pipeline dosing 2. To manually dosing good protection: wear a mask, gloves 3. Packaging and storage 4.25KG / bag, kraft paper packaging 5. Store in a cool, dry, well-ventilated place, can not be stored together with acids VI: Company Profile Beijing (Kunshan) Weak Promise Environmental Protection Technology Co., Tsinghua University graduate technical team created. Patents: heavy metal chelating agent RS100, complex wastewater treatment agent RS200, broken cyanide agents, phosphorus agents, in addition to nickel agents, in addition to network agents. Focused on heavy metal wastewater electroplating wastewater treatment, waste water treatment board, nickel wastewater treatment, wastewater treatment and other zinc-nickel alloy, have reached the national standard Table III. Weak Promise Beijing Environmental Protection Technology Co., Ltd., is located in Beijing's Zhongguancun Science Park, a high-tech enterprise, the core technology from Tsinghua University. The company has a unique heavy metal wastewater treatment technology, research on the 2013 "Intel" Huoerdengjiang Global Innovation Competition, and won the 2014 China Machinery Industry Science and Technology Award prize. Environmental Protection Technology Co., Ltd. Kunshan Weak Promise is located in Kunshan City, Jiangsu Province Economic and Technological Development Zone students Pioneering Park, Tsinghua technical team of high-tech investment in the establishment of environmental services industry in the Yangtze River Delta region. Continuation of the traditional company headquarters in Beijing, adhering to the "actions speak louder than words," the spirit of Tsinghua University, is committed to R & D and marketing model innovation, "Weak Promise" to build a leading electroplating wastewater, heavy metal wastewater treatment technology service provider. The company specializes in electroplating wastewater treatment, waste water treatment circuit boards, wet FGD waste water treatment, etc., through the door and free testing services, targeted a "treatment plan" to provide customers with the most advanced water treatment products and technical services. Has tackled the alkaline zinc-nickel alloy wastewater treatment, chemical nickel wastewater, times phosphorous removal, electroplating industrial park comprehensive wastewater copper, nickel and other aspects of the problem of excessive. In addition to medicine, but also provides a series of supporting efficient water treatment equipment such as sedimentation tanks, catalytic oxidation reactors. Weak Promise its professional skills and the quality of service in the industry get a good reputation, customers widely distributed in the Yangtze River Delta, Pearl River Delta region, Hunan, Sichuan, Chongqing and other places. Combined with related research at Tsinghua University, is expected to introduce more high-tech products in the near future, and gradually form a more perfect system of wastewater treatment technologies.
