Ultrafiltration purification equipment for industrial reclaimed water reuse
Equipment Overview
Ultrafiltration membrane is widely used in industry and has become one of the new chemical unit operations. It is used in separation, concentration and purification of biological products, pharmaceutical products and food industry; it is also used in terminal treatment devices of blood treatment, wastewater treatment and ultra pure water preparation.
Equipment features
The comprehensive acid-base wastewater and complex wastewater are recycled by advanced recycling system. The system adopts advanced special membrane separation technology, with simple process, stable and reliable operation, and high treatment efficiency. This process gives full play to the advantages of special membrane. After the wastewater from circuit board, touch screen and solar photovoltaic is treated by this process, valuable metal ions (nickel, copper, chromium, etc.) in the wastewater can be recycled after membrane concentration, and the permeate of wastewater after membrane treatment can be recycled As process water reuse, it can not only save cost, but also realize zero discharge of wastewater; the quality of reclaimed water is better than municipal water, which can be directly reused to the production line for general cleaning, or used for pure water system to produce DI water; triple permeable membrane technology (i.e. ultrafiltration and high anti fouling system and purification system) is used to effectively control the blocking problem of reverse osmosis membrane, reduce the cleaning frequency of reverse osmosis membrane, and prolong the service life The reuse system adopts Mechatronics design, with PLC central control, high degree of automation, simple operation and maintenance, easy to standardize management, optimize treatment efficiency and reduce human error; the reuse system is equipped with automatic monitor to ensure that the appropriate wastewater is transported to the reuse system. If the wastewater quality is abnormal due to wrong drainage, the reuse system will suspend the inflow until the inflow quality returns to normal; the key components of the system are composed of high-quality imported equipment and self-developed and designed unique system, so as to ensure the long-term stable operation of the system; the industrial wastewater reuse treatment system covers a small area, has few auxiliary facilities, and the equipment configuration is economical and reasonable Less capital, low operating costs. The device is suitable for the treatment and reuse of electroplating wastewater in circuit board, touch screen, solar photovoltaic, automobile, home appliances and other industries.
technological process
The wastewater from the production workshop is separately introduced into each mixing tank for reduction or oil-water separation treatment. After sedimentation, it is pretreated and filtered by micro filter, ultrafilter, nano filter, and then through the two-stage reverse osmosis system. The effluent quality can reach a conductivity of less than 20us / cm2, which can be reused in the workshop as production water. The sludge from the sedimentation tank is dewatered and then outsourced for treatment. The high COD wastewater and * * grade reverse osmosis system are mainly used The concentrated water is discharged up to the standard through the separation system of wastewater treatment.
