Zhejiang sewage treatment equipment

Sewage treatment systems are reverse osmosis desalination apparatus main process, which has a very high desalting capacity. To ensure the efficiency, security and flexibility, the system is running using reverse osmosis system level configurations. Reverse osmosis system consists of four parts high-pressure pump, reverse osmosis membranes Group, and distribution control device. Reverse osmosis technology: Reverse osmosis is enough pressure for a solution, the solvent (general often water) is separated from the solution by a reverse osmosis membrane (a semipermeable membrane). Permeate collection tube leads from the center failed to pass through the ion, organic matter, bacteria, viruses and other impurities from the concentrated water outflow end, so as to achieve the purpose of purification separation. The solution using reverse osmosis technology can be isolated, purified and concentrated. RO features: ① no heating, low energy consumption; ② no phase transition, to maintain the structural characteristics and quality of raw materials; ③ devices are small, simple, adaptable; ④ no acid emissions, does not pollute the environment . ⑤ easy to automate control. Reverse osmosis systems: typically include pretreatment, reverse osmosis, post-processing, cleaning equipment and electrical control components. Pretreatment generally include the original pumps, dosing devices, quartz sand filters, activated carbon filters, softeners, precision filter, etc. (also useful as a pretreatment of UF, called full film treatment), whose main role is to reduce Raw water pollution index and chlorine and other impurities to achieve the reverse osmosis water requirements. Device configuration pretreatment system should be based on the specific circumstances of the raw water may be. RO means including multi-stage high-pressure pump, reverse osmosis membrane element, membrane shell (pressure vessels), brackets and other components. Reverse osmosis plant is the core processing unit, whose main role is to produce pure water (or separation, concentration substances), effluent meet the requirements. After the deal is in the reverse osmosis water can not meet the requirements of the situation to increase configuration. Including one of them Yam bed bed, mixed bed, sterilization, ultrafiltration, EDI, etc., or other equipment. After the reverse osmosis treatment system effluent quality can better improve, so as to meet the higher requirements. Cleaning means cleaning the main tank, clean water pumps, precision components. When the reverse osmosis system contaminated water indicators do not meet the requirements, the need to make it back to the reverse osmosis cleaning effect. Electrical control system is used to control the entire reverse osmosis system to normal operation. Including the instrument panel, control panel, all kinds of electrical protection, electrical control cabinet. Applications: clean water, food, beverage, pharmaceutical, chemical, brewing, power, electronics, desalination, painting and electroplating industries.
