The system is hydraulically automatic and has no control system, power supply or need for operator intervention. It has no moving parts, and no need for replacement parts.
The system provides a multi-barrier approach comprising aeration, clarification, filtration and disinfection targeting micro-biological pathogens, turbidity, suspended solids, particulate iron etc. Where possible the use of treatment chemicals is minimised.
The use of relatively complex conventional drinking water treatment processes used in the developed world is impractical in remoter parts of the developing world due to a lack of skilled operatives, lack of maintenance parts for electro-mechanical & control systems, unreliable power supply and poor access to treatment chemicals.
The ClariWash system is a new concept addressing these challenges. The self-washing system utilises established hydraulic principles in a novel way to periodically self-wash the system such that both the clarifier and the filter are cleaned in one cycle.
WaterReach Ltd is a UK registered "not for profit" company providing solutions for development and disaster response in the WASH sector in support of UN Sustainability Goal No 6 - clean water and sanitation.
