UPVC Filter Housings

Listing ID #4866523

We were the pioneers in introducing UPVC housings in India. Unplasticized Poly Vinyl Chloride (UPVC) filter housings offer a few advantages over stainless steel housings in certain applications and conditions. There are situations where you have to deal with corrosive fluids with a certain economy, UPVC housings come in handy there. They are offered off-the-shelf, hence there is no manufacturing time.

One design brings the water in the top of a container through a “header” which distributes the water evenly. The filter “media” start with fine sand on the top and then graduatingly coarser sand in a number of layers followed by gravel on the bottom, in gradually larger sizes. The top sand physically removes particles from the water. The job of the subsequent layers is to support the finer layer above and provide efficient drainage.

As particles become trapped in the media, the differential pressure across the bed increases. Periodically, a backwash may be initiated to remove the solids trapped in the bed. During backwash, flow is directed in the opposite direction as normal flow. In multi-media filters, the layers in the media re-stratify due to density differences prior to resuming normal filtration.
