Pre filter

Mesh pre filters

Ultrafilters in the UFKM/UFWM/UFMM range can be upgraded by adding an installation kit which includes a 300 micron mesh pre filter. The mesh prefilter can also be ordered separately and will remove the biggest and sharpest particles that might find their way to the ultrafilter. It’s very important to prevent sharp particles from entering the UF since it might harm the hollow fibers and cause membrane leakage.

Bag filters

Bag filtration is a plug and play add-on to the ultrafiltration systems of PB. Various filter houses with various connections can be added to the systems, ask our engineers for a suitable type. Inside the houses a wide range of filter bags can be added, starting form 100 micron and ending at 1 micron.

Meltblown 

Another well known prefiltration technology is melt blown filtration. PB cooperates with high end supplier of melt blown candle filters and offers plug and play sets. Melt blown candles are also used in the PB UFC product line in which they are combined with activated carbon and UF candle filters. Candle filters are very easy to be replaced by any plumber around the world and come in 10” and 20” sizes.

AFM glass filtration

Activated Filter Material glass filters are a great 5micron prefilter for the PB UF modules and systems. With a hight of 185cm and a weight of 193 KG these prefilters are not suitable for every locations. The filter material inside the housing will remove the very fine sand particles, organic matter and oxidised iron. An application can be rainwater filtration, well water filtration or surface water filtration. The backwash possibly on the AFM filter makes it a reliable unit with a great life span.

Ultrafilters

Maybe not the filter you expect to find at this pre filtration page, but ultrafiltration is a very great pre filter for reversed osmose systems or locations with a high particle rate. Ultrafilters of PB will protect the expensive RO membrane from clogging, making the ROI on the UF extremely high. Ask our engineers for a calculation and advise.
