Evina Ltd. is a cleantech company dedicated to the development of a novel biotechnological solution for the long lasting problem of cyanuric acid accumulation in swimming pool water.
Evina Ltd. has a worldwide, exclusive license from YEDA, the technology transfer company of the Weizmann Institute of Science, to develop and commercially exploit the technology developed by Prof. Vivian I. Teichberg, a member of the Neurobiology Department at the Weizmann Institute of Science.
There are about 8.6 million backyard swimming pools in the U.S.A, and about 20 million worldwide.
The chlorine used as a sanitizer in swimming pools, is very unstable due to photolysis by the sun's ultra violet rays. It thus breaks down and loses effectiveness as a disinfectant. In swimming pools, where chlorine stabilizer product such as sodium trichloroisocyanuric acid is used, the by-product cyanuric acid progressively accumulates. Excess cyanuric acid complex with chlorine thereby abolish its disinfection role. In the absence of a dedicated solution the pool water has to be either totally drained or extensively diluted with fresh water in order to maintain the water quality of the swimming pool.
Evina Ltd. is developing a biotechnology-based filter through which pool water circulates and cyanuric acid is removed. The filter consists of a solid support to which the biotechnological entity is immobilized and enables the degradation of cyanuric acid. This biotechnological entity is unique; extremely selective; natural and does not contain add chemicals.
It has been estimated that the USA pool and spa industry worth about $8 billion per year and continues to expand more that 8% annually, driven by:
i) The ever increasing life expectancy and tendency to stay active at old age in Western countries.
ii) Convenience enhanced by improved swimming pool construction technology
iii) Higher demand for branded chlorinated isocyanurates as well as branded and non-branded calcium hypochlorite.
iv) The published data estimated that 69 million households in the U.S. have the financial wherewithal and the yard space to own a swimming pool, but only 11% of those households have one.
