New water system makes waves at aquarium

Elga Process Water has supplied a second MidiRO reverse osmosis system to The Deep, in Hull.

The Deep is an aquarium that combines education, conservation and research and is home to over 3500 freshwater and sea fish including sharks and rays.

Make-up water used to replace the waste water is taken from the mains supply, pre-treated by a Selectron low salt usage softener before passing through the MidiROs low pressure reverse osmosis membrane which removes over 95% of the dissolved salts. The Deep can then remineralise the purified water under controlled conditions to give the precise chemical constituents for their freshwater or seawater aquaria. The reverse osmosis treated water is also pure enough to be used in the laboratories for glassware washing and reagent preparation.

The new compact treatment plant serves as the quarantine facility, where sick fish can be isolated and treated.
