Desalitech to supply wastewater treatment pilot system to LACSD

Water production and treatment solutions provider Desalitech has secured a contract from the Sanitation Districts of Los Angeles County (LACSD) to supply an advanced pilot wastewater treatment system.

The LACSD will use the Desalitech CCD system to meet an order from The State of California to reduce chloride levels in the Santa Clarita Valley's treated wastewater to less than the state's legal limits.

The system is capable of reducing effluent discharge and brine disposal costs, which can represent more than 50% of total water treatment project costs.

Russian oil company Bashneft has selected GE's ZeeWeed membrane bioreactor (MBR) for treatment of refinery water from the Bashneft-Ufaneftekhim oil processing complex in the Ufa industrial block.

The company will provide MBR technology along with electrodialysis reversal, reverse osmosis and ion exchange polishing technologies for the wastewater treatment plant.

In collaboration with Bashneft and the Bashkortostan Institute of Petroleum Refining and Petrochemistry, GE conducted a successful pilot study from April to July as part of its preparation to modernise the biological treatment plants (BTP) of the Bashneft-Ufaneftekhim branch.

Companies to deliver Nereda wastewater technology in UK

Royal HaskoningDHV and Imtech Process have signed a cooperation agreement to deliver the sustainable and biological wastewater treatment technology Nereda in the UK.

Nereda is a technology for wastewater treatment, which operates through an aerobic granule process and will displace the old method of activated sludge. It saves 20% to 30% in energy and around 75% in land use.

Imtech Process anticipates that it will construct five to eight Nereda wastewater treatment installations in the coming years.

The technology was developed in a public-private partnership between Delft University of Technology in the Netherlands, the Dutch Foundation for Applied Water Research (STOWA), Dutch water boards and Royal HaskoningDHV.
