Water treatment by Eimco Water Technologies
Eimco Water Technologies history with the membrane bioreactor (MBR) process goes back to the 1960’s when Dorr-Oliver (now part of Eimco) developed the membrane Sewage Treatment System (MST) process using an ultra filtration membrane module.
In the 1970’s, the technology first entered the Japanese market through a license agreement between Dorr-Oliver and Sanki Engineering Co.Ltd. In 1982 Dorr-Oliver introduced the membrane Anaerobic Reactor System (MARS) for the treatment of high strength food industry waste. By 1993, a total of 39 external membrane bioreactor systems had been used for sanitary and industrial applications.
Today membrane bioreactor (MBR) systems are widely used through out the world, with Eimco Water Technologies designing and constructing over 140 MBR plants in the UK, USA and Australia.
The very high quality of the treated water from an MBR process is common to all Eimco’s commercial systems. Eimco MBR systems are providing high performance, low maintenance, small foot print, on-site processes, capable of high quality treated water suitable for reuse in applications like toilet flushing, irrigation and cooling towers.
Some of the advantages of Eimco MBR systems are: complete solids removal from effluent, effluent disinfection, combined COD (Solids and Nutrient) removal in a single unit, high loading rate capability, low/zero sludge production, rapid start up, sludge bulking is not a problem and modular construction which makes them easy to retrofit.
More recently, a reduction in the cost of membrane modules, combined with the extended life expectancy of the membranes, acceptance of the process capabilities, advantages in process design and operation have all resulted in the MBR process treating large volumes of low strength municipal wastewaters.
In Australia, Eimco is well recognized for stormwater treatment, harvesting and reuse, as well as multiple wastewater treatment plants (packaged or in-situ), but the growth area for the company at present appears to sewer mining (for water reuse) due to its reliability of supply. Of the three sewer mining technologies sold by Eimco, the ReAqua MBR is edging out the other two at present, due to international advances in membrane bioreactors.
