Industrial reverse osmosis desalination consists of the removal of most ions dissolved in water. Salinity is the sum of all the disolved ions present from the dissolution of different salts (not just NaCl or common salt) while water is in contact with different types of mineral soil.

Components of a reverse osmosis system for brackish water

1. Commercial and Industrial reverse osmosis systems

Reverse osmosis (RO) desalination is a process where water containing inorganic dissolved salts and other impurities is forced, by means of a high-pressure pump, to pass through a semi-permeable membrane to produce pure water.

All impurities from water are retained (rejected) by the RO system while the purified reverse osmosis water, also called permeate, passes through the membrane.

Reverse osmosis membranes can separate all suspended matter of any size and 99% of all dissolved salts. However, they are not good at rejecting gases as their molecular size is too small for the membranes.

Reverse osmosis systems are replacing conventional ion exchange technology. The use of RO systems prevents need to store, handle, and dispose of large amounts of acid and caustic chemicals, making reverse osmosis a more environmental friendly technology.

2. reverse osmosis systems for commercial and industrial applications

Watercore engineers collaborate with industry leaders to design energy-efficient reverse osmosis systems specially manufactured for commercial and industrial applications.
The main benefit of these RO systems is that, with a powerful PLC control, energy-saving membranes, electronic pressure, flow and conductivity sensors and motorised valves are constantly optimising the operational settings to deliver the maximum pure water-flow with the minimum power consumption.
This game-changing technology is applicable to multiple industries such as irrigation or waste-water treatment and was conceived focusing on optimised energy costs and high water recovery.

2.1 Energy-saving polyamide ro membranes

Each Watercore reverse osmosis system is designed with energy saving polyamide membranes. This solution is a perfect fit for a wide range of water treatment applications and provide significant cost savings due to lower operating pressures, while maintaining optimal flow production and delivering very pure water.

2.2 smart PLC control

Our RO system also comes with an industrial MODBUS communication that facilitates any integration  in complex industrial environments. These units can be easily controlled locally or remotely by means of a powerful HMI interface and can be programmed to send alarms and notifications by email.

Dry contacts are provided for pretreatment units or storage tanks. When needed they can  can also be controlled remotely with a TCP/IP interface and can be easily programmed to send alarms and notifications by email.

5. Reverse osmosis SYSTEM with multiple configurations

Available as skid-mounted or containerised units, our energy-efficient reverse osmosis desalination systems are available for tapwater, ground water to seawater desalination and cover all type of application including drinking water, irrigation waterblowdown reuse in cooling towersboiler feedwater treatment and other industrial process water.

Default system configuration comes with 25 micron pre-treatment filter and high-pressure pump, however low-pressure pump can be supplied as an optional equipment.

Fabricated in Australia with high quality components our reverse osmosis systems arrive at your facility fully factory-tested and ready to be energised. This way installation, commissioning and start-up times are minimal.

All Watercore commercial and industrial reverse osmosis desalination plants are (CIP) clean-in-place ready, supplied with all the hydraulic connections required for an on-site cleaning of the system membranes. 

Typical production lead time is six to eight weeks, delivery ex-works from our Sydney workshop.
