Microfiltration system

Freshwater Filter and JP Ceramics provide 'whole of house' microfiltration systems that can take water from a contaminated source and treat it to potable standards. The JP5 will treat up to 300,000 L/y, enough for a four-person household, while the JP10 will provide for households with five persons or more with a capacity of 600,000 L/y. The systems can be connected via the pressurising pump to the point of entry to the dwelling and operate on an 'as required' basis, or can be run periodically to fill the tanks that supply the dwelling.

At the heart of the system are easily cleaned ceramic filter elements with an absolute rating of 0.5 micron. That means 99.99999+% of particles of 0.5 micron and above are retained by the filter. 99.28% of particles of 0.2 micron and above are retained by the filter. This means parasites such as Giardia and Cryptosporidium, amoebae and disease-causing bacteria such as E.coli, other coliforms, cholera, typhoid, dysentery are eliminated. The elements are self-sterilising and can additionally be packed with activated carbon and/or resins to significantly reduce contamination due to herbicides, pesticides, nitrates, chlorine and heavy metals if these are, or are suspected to be, present in potentially harmful quantities in the water supply.

Where the incoming water supply is very turbid with suspended particles, the fine filters are protected by inexpensive non-ceramic filter elements arranged in series from 20 micron down to 1 micron, depending on the severity of the contamination.

Whole of house/point of entry systems are provided with stainless steel housings for the ceramic elements and a choice of stainless steel or plastic housings for the non-ceramic elements.
