A portable flocculation, filtration and chlorination system

A portable flocculation, filtration and chlorinisation system intended for the purification of non-saline water drawn from a variety of sources e.g. surface water, river, borehole etc. to drinking water conditions. This is achieved by the already flocculated water passing through two primary filters. Chlorinisation takes place by the use of a water-driven dosing pump capable of dosing at the rate of 2ppm and upwards as required. The water then passes through its final stage of purification where use is made of an advanced filter media. This media is self-sterilising because of its permanent high surface catalytic properties and negative zeta potential. The negative zeta potential allows the filter media to adsorb positive charged metal ions from the water such as iron and manganese. The water having passed through this filter is of micron or sub - micron standard. The treated water is then stored in an incorporated holding tank ready for later use as and when required. This stored water is used when it becomes necessary to backwash the system. Such a high degree of efficiency has been achieved in the backwashing system that the filter media will never need to be replaced. Further polishing of the water may be achieved through the use of a specially designed activated carbon system which brings the water to bottled water standards. The water treatment unit may be carried on a trailer which incorporates its own specially designed flocculation and header tank rendering the unit of special usefulness in disaster and relief situations and also for the military on manoeuvres etc.
