EED WATER IS SUITABLE FOR ULTRAFILTRATION Not all water is suitable for filtering through the Ultrafiltration Unit UF and testing for unsuitable contaminates should be undertaken before use e YES Diseases Removed The ultrafiltration unit will significantly remove biological contaminates and pathogens including bacteria viruses protozoa cysts parasites etc making water safe to drink e YES Turbidity Removed The ultrafiltration unit will remove turbidity and dirt from water Dirty water can however damage the filter fibres and it is recommended to install a pre filter e NO Chemicals Not Removed The ultrafiltration unit will not remove salt or dissolved chemicals and minerals from water FLUSH CHLORINE SOLUTION THROUGH WATER PIPES amp CONTAINERS TO PRVENT DISEASES It is good practice to soak and flush water pipes drinking containers hoses taps and other equipment with a 0 1 1 000 parts per million chlorine solution to eliminate any residual or accidental contamination Add approximately 1 teaspoon of chlorine powder to 5 litres of water and use this to flush through pipes or wash drinking water containers It is also recommended to regularly flush a chlorine solution through the ultrafiltration unit and out through the drinking water hose to eliminate any reverse contamination PRE FILTRATION TREATEMENT It is highly recommended that a pre filter be installed to reduce solids from fouling the in
