Company History

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.

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.

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.

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.

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.

2002 - The Marvin Group acquired CWT.

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 bioreactors.

2004 - CWT starts marketing the GEM system.

CWT Company Profile

Funded in 1996, Clean Water Technology has focused on improving the technology for the waste water industry. With over 20 patents in the field of flotation and flocculation, the company is the leader of the flotation and flocculation systems through its GAS ENERGY MIXING System (“GEM”).

The Company has offices in Los Angeles, CA and in Mexico, and we provide our products throughout the globe.

Research & Development - Clean Water Technology has a twenty-year history of research and development in water sciences. Clean Water Technology continues to develop products for efficiency, user-friendliness and state-of-the-art performance. We have dozens of patents on technologies that improve liquid/solid separation, gas entrainment, mixing, dewatering, metering, controls and accessories, as well as complete systems that pull the entire product range together into an effective package that is easy for our customers to use.

Laboratory Analysis - Clean Water Technology maintains a facility in our Los Angeles, California location for the testing and analysis of our customer’s water samples and continuous evaluation of our R&D projects. In this laboratory we can perform tests that will accurately predict the effects of our full scale on-site systems, giving our clients the accurate information they need to make major investment decisions regarding their facilities and future growth strategies.

Pilot Studies - On occasion, a client comes to us with a problem that is outside the scope of our activity. An on-site pilot study can help to answer questions that cannot be accurately predicted in a laboratory setting. Seasonal products, especially delicate or unusual ingredients with unusually short shelf lives, are prime candidates for this type of on-site analysis. Our Pilot Demonstration System is capable of processing a 5 to 50 GPM side-stream on site with a wide variety of chemical combinations. This system sets up in a day and provides real time data that cannot be duplicated any other way for our customers with special needs.

Consulting & Engineering - Clean Water Technology has a twenty-year history of research and development in water sciences. We bring this talent to bear on every installation. CWT sells Engineered Systems that are designed to work. In order to be successful, we made our systems to fit into our customer’s existing workflow and not be too disruptive for the staff that must oversee the operation of the equipment.

Customer Service - Our customer service begins with our first phone call and continues throughout the life of our product's integration in your company. Clean Water Technology believes that we are only as good as our customers think we are. Our installations are monitored and maintained by our highly trained staff of technicians.
