BioShaft Water Technology has been awarded several industrial and domestic contracts to install wastewater treatment and recycling systems in the Middle East, including two for its Turbo Moving Bed Bio-Reactor (T-MBBR).
BioShaft said that the system requires about 50 percent less energy than conventional treatment facilities, and its underground installation requires less land use and also can operate under extreme temperatures.
According to the company website, the T-MBBR system treats flows from small populations or large-scale municipal sewage works by varying turbine depth and diameter. The system uses a moving bed of bio-film carriers that collect very high biomass concentrations, the website said.
The process reduces biological sludge production and cuts inorganic solids to less than 50 percent by eliminating all suspended bacterial presence in the bioreactor, BioShaft says.
While a conventional suspended growth system requires large aeration and sedimentation tank volumes, the T-MBBR significantly reduces these volumes by using biomass carriers with a high specific surface area. The organic loading rates achieved significantly exceed those of conventional activated sludge wastewater treatment systems, and intensify the mitigation process, the company website says.
BioShaft also has a modular system that scales with a variable number of units based on the needs of the plant configuration or phased work.
Its new contracts are as follows:
Delmon Poultry, Al-Manama, Bahrain: A packaged above-ground concrete Modular Anoxic Aerobic Digester (MAAD) system will recycle high-strength industrial wastewater for reuse in irrigation.
The King Abdullah New Financial District, Riyadh, Saudi Arabia: A residential/institutional T-MBBR system will treat 132,000 gallons per day of domestic wastewater from a housing complex.
Jeddah Gates, Jeddah, Saudi Arabia: A temporary, packaged, containerized T-MBBR system will treat domestic wastewater from a high rise tower. The system has a capacity of 55,000 gallons per day.
EMMAR Middle East, Dubai, UAE: A mobile temporary system will treat domestic wastewater for a residential development that is not connected to a municipal sewer network.
