Description:
Commonly used water treatment approaches to mitigate phosphorus pollution and its consequences in small watersheds include the use of chemicals to precipitate phosphorus or algaecides to terminate algal growth. Both approaches require the addition of chemicals to the waterbodies resulting in biomass/sludge build-up, solid precipitates and/or potential toxicity from added metal salts. There is a high demand for alternative technologies. GreenTechnologies’ (GT) phosphorus adsorption filter is a disruptive innovation that fills a void in the water treatment industry and addresses the market demand. GT has identified the aquaculture market, a $2.8 billion annual water treatment market and community and resort lake and pond treatment market, a $993 million annual market, as initial entry points. Unlike existing technologies, GT’s phosphorus adsorption technology can reduce phosphorus to below detection limits, allowing for effective treatment of stormwater outfalls that are not currently being managed. Removed phosphorus can then be beneficially reused in other industries. GT’s phosphorus adsorption technology eliminates the need for chemical additives and costly sludge management, making it a more environmentally sustainable approach to water treatment than existing alternatives in the market. GT has acquired customer and distribution partners and potential toll manufacturers as it progresses towards commercialization of its technology.Supplemental Keywords:
