This equipment can make seawater get rid of mineral, Pb ppm, organism and bacteria and many others, and become ultra clean and clear freshwater which meets the national drinking water quality standard.. 

The system has installed a new body case with all pipes made of resistant material, so that the whole system can use a long time.

RO system has adopted advanced RO system components and high-quality membrane elements, and has been designed according to the equipment's output combining with unique efficient technology so that the system can save much energy.

More advanced devices have been installed in this system, such as flow and pressure control meters, atmospheric valve and blow down piping, which make sure the whole system works stably, safely and conveniently.


System Components & Introduction
 
Feed pump:
Single water flow: 1m3/h
Head of delivery: 38m
Power: 0.46KW
 		 Brand name: Grundfos (Optional)
Providing backwashing and rinsing engine for multi medium filter and precision filter.
Multi Medium Filters:
Ø200x1150mm
 		 Multi-media filter is mainly to remove the large particle material, such as algae, the rusty, etc. With unique water distribution way, it makes the raw water pollution index and turbidity to a minimum.
 
Precision Filter:
2m3/h, 5μm
 		 Fiberglass precision filter holds filter cartridge with 1μm in its inner, which can impede particles (>1μm) of raw water and ensures RO Membrane would not be scratched by large-grained suspended matter.
 
High Pressure Pump: Brand name: Grundfos (Optional)
The effect of high pressure pump is to provide enough input pressure for reverse osmosis device. According to the nature of reverse osmosis itself, a certain degree of driving force is needed to overcome osmotic pressure and other resistance and to reach the specific productivity designed.
 
Reverse Osmosis System: RO Membrane: DOW(Optional)
RO system is the central desalination unit in this system, almost all soluble salt, colloid, organics and microbe will be cleaned out by applying the RO membrane's peculiarity.
 
Rinse System: RO system after running chronically, it can be polluted by some substances rinse out hardly. Micro-salt and organics scale chronically to make film performance decline, operating pressure go up, so system must be rinse with chemical agent, so that it return to normal.
 
Site Online Monitoring Instruments:
 		 In order to monitor the normal operating and realize automatic operation under certain conditions, we have equipped with site online monitoring and control instruments in the system, which includes: Pressure Switch, Safety Valve, RO output conductivity meter, Output Rota meter.
