seawater desalination equipment The water quality of seawater desalination equipment after desalination is even better than tap water, which can be used by industry, commerce, residents, ships, and ships. The reverse osmosis membrane method first extracts seawater for preliminary treatment to reduce seawater turbidity and prevent the growth of microorganisms such as bacteria and algae. Then, a special high-pressure pump is used to pressurize the seawater to enter the reverse osmosis membrane. Due to the high salt content of seawater, the seawater reverse osmosis membrane must have characteristics such as high desalination rate, corrosion resistance, high pressure resistance, and pollution resistance

Product details: The water quality of seawater desalination equipment after desalination is even better than tap water, which can be used by industry, commerce, residents, ships, and ships. The reverse osmosis membrane method first extracts seawater for preliminary treatment to reduce seawater turbidity and prevent the growth of bacteria, algae, and other microorganisms. Then, a special high-pressure pump is used to pressurize the seawater to enter the reverse osmosis membrane. Due to the high salt content of seawater, the seawater reverse osmosis membrane must have high desalination rate, corrosion resistance, high pressure resistance, and pollution resistance. After being treated with the reverse osmosis membrane, the salt content of the seawater is greatly reduced, The TDS content has decreased from 36000mg/L to around 200mg/L.

1、 Product composition

The reverse osmosis membrane element is the core component of reverse osmosis seawater desalination, which has better pressure resistance and oxidation and pollution resistance performance of over 99%. The reverse osmosis device adopts a combination structure of multiple membrane components connected in series and multiple pressure main pipes connected in parallel, and is equipped with low-pressure automatic flushing and discharge and low-pressure automatic flushing and replacement of desalinated water, as well as automatic switching and discharge devices for unqualified production water. In this system, high and low pressure protection and high-pressure pumps are also installed, and the interlocking of the cleaning pump is also installed.

2、 Product parameters

Brand: Rojas Water Treatment

Model: Professional Customization

Water yield: 0.25T/Hr to 20T/Hr

Inlet water quality: seawater or high salt water, meeting relevant inlet water indicators.

Production water quality: meets the standards for reuse water quality and concentration rate.

3、 Control system

The entire reverse osmosis seawater desalination control system adopts the Pure V1.0 water treatment control system. Set high and low pressure protection switches and automatic switching devices according to process parameters. In case of abnormal conductivity, flow rate, and pressure, automatic switching, automatic interlocking alarm, and shutdown can be achieved to protect the high-pressure pump and reverse osmosis membrane components. Variable frequency control of the start and stop of the high-pressure pump, achieving soft operation of the high-pressure pump, saving energy consumption, and preventing damage to the high-pressure pump and membrane components due to water hammer or back pressure. The program design can achieve low-pressure automatic flushing before and after the startup and shutdown of the reverse osmosis device. Especially during shutdown, the metastable state of concentrated seawater will transform into sediment, contaminating the membrane surface. The low-pressure desalination water automatic flushing can replace the concentrated seawater, protect the membrane surface from pollution, and extend the service life of the membrane. The system's temperature, flow rate, water quality, production and other related parameters can be displayed, stored, counted, tabulated, and printed. The dynamic process flow screen during operation is clear and intuitive, and the system control simplifies manual operation, ensuring that the system can operate automatically, safely, and reliably.

4、 Application field

(1) Used in offshore oil drilling platforms, islands, wilderness, marine engineering fields, oil drilling platforms, reefs, and other places.

(2) Concentrate high salt wastewater.

Seawater desalination equipment is an open-source incremental technology that produces fresh water through seawater or high salinity desalination, achieving the utilization of water resources.
