Spheritech have now proven that a simple biopolymer can be used to remove lead from domestic water supplies. Although it is well known that the lead content in many millions of UK homes and, more frighteningly, in thousands of schools, exceeds safe legal limits there is a lack of interest from utility companies to solve the problem. It is simpler to pay the fines rather than solve the problem. Spheritech are open to offers for collaborative development of technology which works. Cartridges containing this environmentally friendly biopolymer have now been shown to exceed 12 months life-time for usage in an average household. The company also have scalable environmentally friendly technology that could be applied to schools and areas of major concern such as hospitals.
