Clean Water Technology

2008 - CWT now offers full treatment solutions for both water and wastewater treatment. 2008 - Clean Water Technology relocates to a 40,000 square foot facility in Los Angeles, CA. 2006 - CWT expands its product offerings and begins marketing biological systems. 2004 - CWT starts marketing the GEM system. 2003 - CWT developed a hybrid centrifugal flotation dissolved air flotation system termed the Gas Energy Mixing (GEM) system. It incorporates all advantages of the centrifugal flotation and dissolved air flotation, and is based on the LCPP and LSGM systems. With less energy used than any traditional DAF, the list of benefits include: Less noise created, better efficiency for contaminant removal, less chemicals required due to enhanced mixing, facilitates faster operator response from changes of influent water, instantaneous mixing of coagulants and flocculants (eliminating floc tanks and basins), higher maximum contaminant capacity for influent water (as much as 12% solids and greater, up to several times greater than a DAF system). Due to these benefits and the ability to closely monitor the amount of chemicals used (which prevents chemical overdosing and membrane fouling), the GEM system is a highly viable option for pre-treatment of waste water upstream of membrane filtration equipment. It is also discovered that the LSGM is an excellent aeration device, which makes it possible for incorporation into aerobic bio-reactors. 2002 - The Marvin Group acquired CWT. 1998 - CWT developed further modifications of the centrifugal flotation concept based on the Hydrocyclone chamber. New liquid, solid and gas mixing devices, unlike the original Hydrocyclone, can now vary in mixing energy and adjust energy as needed for optimum flocculation. This allows for the addition of chemical additives and optimum liquid-solid separation without floc destruction, thereby eliminating carry-over of solid contaminants in effluent wastewater streams. These mixing devices are termed Liquid Cyclone Particle Posistioner (LCPP) and Liquid Solid Gas Mixer (LSGM). Numerous patents and journal articles were submitted, and CWT markets the BAF system. 1997 - CWT modified ASH to improve the efficiency and removal of suspended contaminants from the wastewater streams. This results in the development and commercialization of the Babble Accelerated Flotation (BAF) unit. Numerous patents and journal articles submitted. 1995 - CWT management identified that solid - liquid separations in wastewater treatment based on multiphase phenomena is the most suitable area for the company growth. Flotation technologies become the primary R&D interest. CWT acquired a license for the Air Sparged Hydrocyclone (ASH) flotation technology from the University of Utah. Such centrifugal flotation systems have smaller footprints, faster response times and much larger capacities (regarding more contaminant loading than classical dissolved air floatation units), but efficiency improvements were still needed. 1994 - CWT scientists discovered that the mechanism of action of non-chemical (magnetic, electromagnetic, hydrodynamic, cavitation, acoustic, etc.) water treatment is essentially in the modification of multiphase phenomena (gas/liquid/solid interfacial phenomena). Numerous patents and journal articles submitted. 1993 - CWT was founded with the purpose to develop novel water and wastewater technologies based on recent fundamental science and engineering developments. The company was initially active in the area of no chemical water treatment.
