3M High Flow Cartridge Filtration for Water Treatment meets NZDWS2008.
FILTEC have installed 15 of the 3M High Flow Filter Housings over the past four years. These units, when fitted with a 1 micron absolute rated filter, have been approved to NZDWS2008, after testing at Massey University to prove 3 log removal of Protozoa.
The 3M High Flow filtration system is designed for low turbidity clean water, and has proven to be a very cost effective method of gaining an extra 2 logs credit.
One example of a successful installation is Waitaki DC’s Waihemo WTP, located in Palmerston. This is a bore site which pumps under high pressure (10 Bar) up to storage and then reticulation. Two High Flow housings, with 3x 40” cartridges, were installed at the WTP site. One High Flow is fitted with 5 micron cartridges as a pre-filter and the final filter was fitted with a 1 micron cartridge.
3M High Flow HFR Series filter cartridges are high flow capacity, high efficiency, inside to outside flow direction liquid filtration cartridges, designed for applications with large flow requirements.
The large diameter, pleated depth media cartridge design permits flow rates of up to 500 gpm in a single 60” length cartridge.
This results in significantly fewer required filter cartridges for a given flow than standard 2.5” diameter filter cartridges.
