BLUE-tec - Colubris Cleantech products

The feed is concentrated; Dilution of the draw solution; Draw solution needs to be recovered; Permeate is produced.

Ammonia recovery from centrate: Selective removal of ammonium; Produces liquid fertilizer; No greenhouse gas emissions (N2O); Less use of primary energy than biological processes like Anammox.

Hydrophobic membranes for water vapour transport; Driving for based on difference in vapour pressure; Compact and scalable; Use of low grade thermal heat of 60 to 80 C.

In membrane bioreactors membrane (MBR) filtration is combined with a biological process. The membrane filtration process can be a pressure driven membrane like UF, but alsoFO, the Osmotic Membrane Bioreactor (OMBR).  The biological process can be either aerobic or anaerobic. Advantage of the O-MBR is the low fouling tendency of the FO membrane and the excellent treated water quality after the RO-process ready for reuse.

(O)MBR`s can be applied for the treatment of : Industrial wastewater. Wastewater from the waste processing industry.
Domestic wastewater. Wastewater on board of ships and off shore locations.

BLUE-tec has knowledge of several complementary technologies. These technologies are applied in several projects and can be distinguished in several fields. Pre-treatment technologies like sieves, screens, sand filters, flotation, etc. Post treatment technologies like activated carbon filtration, disinfection, Dewatering technologies like centrifuges, belt presses, evaporators and crystallizers.
