In 2006, SCIMEE Group invented ReCoMag, a magnetic force-based water treatment technology that allows isolation of nonferromagnetic solids from wastewater with its rare-earth magnet disc (ReMagDisc) separators, opening an avenue to develop magnetic force-based universal water treatment system. The principle of ReCoMag is simple. The technology takes advantage of conventional coagulation and flocculation reaction, preconditions wastewater with ferromagnetic microparticles (aka MagCarrier), allows co-precipitation of MagCarrier and solids into flocs and consequently renders nonferromagnetic solids in the flocs tractable to magnetic force. The flocs can then be readily isolated by a powerful magnetic device, ReMagDisc, without the requirement of their gravitational settling. In practice, the ReCoMag system has four components that perform distinct functions and also coordinate with each other. 1. An automatic chemical injection manifold dispenses coagulant, flocculant and MagCarrier. 2. A coagulation reactor allows co-precipitation of solids and MagCarrier to occur adequately. 3. A ReMagDisc separator continuously isolates MagCarrier-containing flocs without the requirement of their gravitational settling. 4. A magnetic drum recovers MagCarrier from sludge and recycles MagCarrier back into the coagulation reactor. SCIMEE's researchers and engineers have created various versions of the ReCoMag system that have been optimized for municipalities and different industrials. Each ReCoMag version has rapidly gained momentum in its target market since launched. The success of the ReCoMag system can be attributed to its key advantages compared with the conventional wastewater treatment approaches. These advantages include high processing capacity, high treatment efficiency, low capital and operation cost and small footprint. In addition, it is energy-saving, because ReMagDisc does not need electricity to elicit magnetic force. Last, more than 95% of MagCarrier can be recycled for reuse and the whole treatment process takes only 3-5 mins.
