Reverse Osmosis Filtration Plant

Hydra-Clear Process Water Install Reverse Osmosis Pre- Filtration Plant

S1032086

Our customer, a large bio-diesel manufacturer, experienced reverse osmosis membrane fouling. Working with our partners, ChemAqua, it was found that the raw water supply was high (<95%) in suspended solids between the 1µm – 3µm range.

The existing pre-treatment was a single 5µm filter cartridge. The effect of the particulate was blockage of the membranes, with the membranes losing efficiency in less than 1 week.

Hydra-Clear Process Water was tasked with removing particulate down to 1µm absolute


The plant is a 40m3/hr system fed from a central control panel. S1032087All operations are automatic controlled, with web based monitoring included as standard.

The bulk of the reduction of fine particulate is performed by Turbidex filtration, a tried and tested media with good adsorption properties. The Turbidex filters are back-washable extending the life beyond conventional cartridge filter technologies.

To achieve the 1µm absolute the water leaves the Turbidex filters through a duplex (duty/ standby) stainless steel 40m3/hr filter housing with 1µm absolute filter cartridges. The 1µm housings are fully automated with differential pressure monitoring and auto change over once the filters become blocked.
