Industries such as automobile manufacturing, automotive parts, bathroom, hardware, and machining generate surface treatment wastewater and heavy metal wastewater during the production process. The direct discharge of these wastewater can cause certain pollution to the surrounding environment. Its heavy metal content is high; The removal of small molecule organic compounds generated by the production line, as well as the removal of silicon and hardness, is difficult; High COD content in degreasing wastewater; Degreasing lotion and chemical nickel are not easy to handle. Therefore, for the treatment of surface treatment wastewater, Protection needs to construct a targeted surface treatment wastewater treatment system project based on the specific situation of each production enterprise and the local industrial wastewater discharge standards, in order to ensure efficient and stable operation of the wastewater treatment station after completion.

Protection Technology Co., Ltd. is an environmental protection enterprise with foreign investment from the Netherlands. The founder of the company has over 38 years of experience in the European environmental protection industry, and has served many Fortune 500 companies including Mercedes Benz, Bosch, Corning, Geely, Ideal New Energy, Baosteel, Kohler Kitchen and Bathroom, Deli, Gree, Fotile, etc. Environmental protection equipment is widely used in industries such as electronics, semiconductors, automotive manufacturing, surface treatment, electroplating, new energy, new materials, precision machining, and fine chemicals.

As a professional industrial wastewater treatment environmental protection equipment engineering technology company that provides one-stop solutions for wastewater reuse and zero discharge,Protection analyzes surface treatment wastewater treatment technology methods for surface treatment enterprises, provides targeted customized surface treatment wastewater treatment process technology solutions, and builds stable and compliant surface treatment wastewater treatment environmental protection equipment projects.

For the treatment of surface treatment wastewater,Protection has built new raw water collection tanks for heavy metal (copper, nickel, chromium, zinc) wastewater, cyanide containing wastewater, fluorine-containing wastewater, oily wastewater, chelating wastewater, waste acid and alkali, and high concentration tank solution based on the previous analysis of raw water quantity and quality. The customer will take over their production wastewater and discharge it into the existing raw water collection tank/pit for collection. This project will equip the above raw water collection tanks and pits with independent lifting pump devices, and then discharge them into the new heavy metal surface treatment wastewater treatment system for treatment. Thus achieving the goal of stable and compliant emissions. For surface treatment enterprises with strict requirements, Protection adopts surface treatment wastewater deep treatment technology to reuse surface treatment wastewater for production after deep treatment, thereby achieving zero discharge of surface treatment wastewater. The overall recovery rate of the system can reach over 95%, and the conductivity of the produced water is less than 10uS/cm
