Printed circuit board wastewater treatment facility

Pcb in the production process, the main pollutants of acid, alkali, Cu, SS, and COD, etc. To clean waste water emissions of resources, conserve water, and access to certain economic benefits, achieve win-win "development development" and "protecting the environment", Huiyuan company to clean wastewater reuse treatment, can not reuse wastewater treated by wastewater treatment plant reach Guangdong local standards, "water pollutant discharge limits" (DB44 / 26-2001) level standards. It can reach the essence of water reuse, in line with international standards ISO 14000, reducing pollution of the social environment, while reducing the cost of circuit board manufacturers. Circuit board production process water reuse system each wastewater plant system, the introduction of each and mix thoroughly separate pool, restore or oil-water separation and other treatment, after precipitation through micro filter, ultrafilter, nanofilter preprocessing filter, and then through the secondary reverse osmosis system, which the water quality can be achieved by a conductivity less than 20us / cm2, can be reused to shop for the production of water; subcontract treatment sedimentation tank sludge dewatering; high COD wastewater second stage reverse osmosis system of the concentrated water through wastewater treatment systems discharge standards. ※ The integrated complex acid wastewater and water reuse systems by advanced recovery. ※ reuse water quality better than municipal water, can be directly returned to the production line for use in general cleaning, or for pure DI water system manufacturer. ※ using triple permeable membrane technologies (ie nanofiltration and high anti-fouling systems and purification systems), effective control of clogging the reverse osmosis membranes, reverse osmosis membranes to reduce the frequency of cleaning and prolong the life of the membrane, and reduce the cost of water recycling. ※ reuse system is controlled by a central PLC, optimized efficiency and reduce human error. ※ reuse system with automatic monitoring instrument to ensure proper delivery to reuse wastewater system. If the error is not normal drainage lead to waste water quality, water reuse system will be suspended until water quality returns to normal. ※ The key components of the system, made of high quality imported equipment, to develop and design a unique system formed, in order to ensure long-term stable operation of the system.
