The AMBC is Modern Water’s All Membrane Brine Concentrator process. The AMBC is an innovative solution capable of reducing waste water treatment requirements and maximising clean water reuse, in a wide range of industrial applications, including:
Around the globe populations are rapidly growing and industries are expanding. Water is now a scarce and valuable resource. Water is used as part of almost every industrial process and many of these industries will have large waste water streams with high salt concentrations (“brine”) requiring treatment. Historically much of this waste water would have been discharged into streams and rivers, polluting the environment.
Now things have developed, environmental laws require companies to treat and responsibly dispose of waste water sometimes as onerous as ZLD, so companies do not discharge any liquids into the environment. This is often done with large thermal brine concentrators and crystallisers which evaporate the water and leave only solids for disposal. This is an expensive and inefficient method as the energy requirements are very large. The efficiency of this process can be increased by pre-treating the water with a lower energy ‘brine concentration’ process, so as to reduce the volume of waste water requiring thermal concentration.
What is the AMBC?
Modern Water’s AMBC is a cost-effective and proven technology for brine concentration. It is based on the concept of forward osmosis and utilises bespoke semi-permeable membranes to separate pure clean water from concentrated brine streams. As it exploits the power of natural osmosis, it is capable of processing highly concentrated brine streams and breaching the boundaries of a traditional reverse osmosis process.
The AMBC utilises revolutionary membranes and electrically driven pumps, to efficiently concentrate brine waste. The AMBC is capable of taking concentrated brine solutions and extracting clean water for reuse leaving a much more concentrated brine stream for final treatment.
Working with partners in various countries, including India and China, Modern Water is able to offer state of the art bespoke brine concentration solutions across the globe.
The AMBC process has been successfully used for concentrating a waste stream in an industrial dye manufacturing facility in India. The AMBC receives RO reject waste water from a reverse osmosis plant and concentrates this further before the AMBC reject is fed to a multi-effect evaporator. This is dirty and challenging waste water but the AMBC has been reliably operating since it was commissioned in May 2018.
In China the AMBC technology is being used to concentrate a Flue Gas Desulphurisation (FGD) waste water from a coal power plant. As China is bringing in new regulations, this is a rapidly growing market and in partnership with Sunup Modern Water will play a major part in solving the waste water problems introduced by the FGD processes.
The AMBC can be utilised as either a standalone process to concentrate a new waste water stream or added onto an existing process to increase the performance or increase the efficiency. There are a variety of different waste water streams the AMBC can be used with, including:
Unlike other brine concentration technologies the AMBC does not require thermal energy to run, as it is purely electrically driven. It has a low power consumption, it is simple to operate and cheap to maintain. And it can be used on its own or bolted on to existing waste water treatment systems.
