Ultra Pure EDI Components opened for business, continuing the O'Hare Legacy in water purification. Starting with My Grandfather Harry O'Hare, knows water. He invented Ty-D-Bol, the toilet bowl cleaner, and helped pioneer the use of chlorinators to clean swimming pools. O'Hare believed that he has designed the next innovation in water treatment: an electro-chemical process that cleans and softens a household's water supply far better than other systems on the market. The product, called the Watergizer, is being developed by HOH Water Technology Corp., a Newbury Park firm organized by O'Hare in 1979 that went public last June and raised $4.6 million.In 1977, Harry O'Hare began experimenting with EDI and created the first working prototype. Prototype testing was done at Southern Research Institute (SRI). This ground-breaking work led to the founding of HOH Water Technology, Inc. in 1979. HOH applied for the first EDI patents in 1981, which were issued in 1984, preceding the Millipore/Ionpure patents by two years. During the product development years of 1981-1989 a wide variety of EDI prototypes were designed and tested by Harry and Ronald O'Hare, including cylindrical EDI in a pressure vessel. With its new technology launched, the company went public.
