Composition of reverse osmosis marine water generator:
Water intake system, pre-treatment system, desalination and desalination system, energy recovery system, chemical cleaning system, chemical dosing system, and device power supply and distribution and automatic control system. The complete set of equipment consists of a pretreatment system, a reverse osmosis system, an electrical control system, a cleaning system, and a dosing system.
The pre-treatment system includes a water supply pump, a multi-media filter, a precision filter, and a security filter. It mainly processes large particulate impurities, residual chlorine, and fine particles contained in the raw water to ensure the quality of the incoming water to the reverse osmosis system.
The reverse osmosis system includes a high-pressure pump, RO reverse osmosis membrane components, pressure regulating valves, and a cleaning tank, which mainly processes the pretreated raw water into fresh water.
The basic process flow of the reverse osmosis marine water making equipment is as follows: seawater is pumped by the water supply pump into the pre-treatment system, and after adding bactericides and flocculants through the chemical dosing system, it enters the quartz sand and activated carbon filtration system for filtration. After passing through the pre-treatment system, seawater enters a high-pressure pump. Under the action of the high-pressure pump, it flows through a high desalination rate coiled membrane. By controlling the pressure regulating valve, the pressure is increased, allowing some pure water in seawater to pass through the membrane and enter the porous collection pipe, leaving the equipment through a hose, while salt is blocked on the membrane surface and discharged from the equipment along with most of the seawater. After water quality reduction, PH adjustment, and scale inhibitor addition, the filtered water enters the 5um security filtration system. One way of filtered low-pressure seawater enters the high-pressure pump for pressurization, and the other way enters the pressure exchange type energy recovery device. After pressurization, the pressurized seawater is mixed with the high-pressure pump effluent and enters the reverse osmosis membrane stack system. Under the treatment of the membrane stack, high-pressure seawater partially permeates the membrane to form fresh water, which enters the fresh water tank for storage after water quality adjustment. The remaining high-pressure concentrated water enters the pressure exchange energy recovery device to recover energy and is discharged.
