Description

1. Brief introduction of Borehole Water RO Machine

High salt content borehole water TDS 7000ppm RO machine. With high salt rejection RO membrane for DOW FILMTEC and high corrosion resistant Grundfos pump. automatically anti-scalant dosing control. Flushing at the beginning of machine start and fresh water fill into the membrane housing when machine stop.

B2K7 series are used to treat brackish water with TDS from 5000 to 7000ppm. The system adopted the world’s most advanced reverse osmosis technology. Different models are designed as per different feed water salt content and capacity. The quality of output water meets the WHO drinking water standard.

2. Features 

►Use DOW FILMETEC design software to calculate and simulate, providing the theory guideline for design.

►We design different systems according to feed water quality and required capacity, the B2K series are applicable to the raw water with salt content 5000ppm-7000ppm.  If salt content is above 15000ppm pls choose SW series for seawater.

►Water quality(TDS) monitor device to ensure stable output quality.

►High salt rejection, service life longer than 3 years, low operation and maintenance cost.

►PLC automatic control.

►Unique fresh water automatic replacement device to replace concentrate in the membrane with fresh water when system stops to reduce membrane pollution, therefore prolong the service life and lower cost.

►Carbon steel coated and stainless steel frame for choice, moving wheels can be installed for different installation situation.

►Stainless steel and SCH80UPVC pipelines with high quality to ensure no leakage and low corrosion under high pressure.

3. Application for Borehole Water RO Machine

Daily drinking water for buildings, hotel rooms, factories, schools,  etc.

For mobile working organizations such as ocean voyages, drilling units, field exploration, tec.

Desalination of water used in production techniques.

4.Technical route and flow diagram instructions

The technical route is as following.

Raw tank–> sand filter–> carbon filter–> anti-scalant dosing system –> sediment filter–>high pressure pump–>RO desalination device–>CIP system–> permeate tank
