Aquafilters remove biological contaminants from untreated water to make it safe to drink.
They have been designed and developed especially for use in developing countries in situations where there is no supply of clean water. Aquafilters may also be an appropriate solution in situations such as natural disasters.
Aquafilters are easily portable and provide instant drinking water at the point of use. They typically treat water from open wells, ponds, lakes, rivers, or harvested storage.
They are operated by hand pumping, and no chemicals are employed in the treatment. To see how easy Aquafilters are to operate, please click here
Aquafilters are easily accepted by the users, as the treated water looks crystal clear, and the flow rates are high enough for immediate use.
Cleaning
A mesh pre-filter protects the membrane by removing larger particles of dirt. The pre-filter can be removed and cleaned when necessary.
The very small particles are removed from the membranes by continuous cross flow, and when necessary by back flushing.
Aquafilter’s hollow membranes are designed to be chemically cleaned in the event of internal biofilm growth. Each Aquafilter comes with NaDCC tablets stored in a built in reservoir. This chemical cleaning restores the flow rate.
Maintenance
The pump seal is the only part that wears. Its life is increased by applying grease which is stored in a grease pot within the casing of the filter. Spare seals are stored on the piston rod (or in the case of the Mark 2 Aquafilter Family, in the pump handle) and are easily accessed if the seal needs changing.
