Fine Filtration

What is Pre-filtration in Rainwater Harvesting Systems?

Pre-filtration or Fine filtration is the first steps in an effective rainwater harvesting systems. Pre-filtration means the filtration of harvested rainwater from the catchment area before it undergoes the storage.  Many of the systems perform the fine filtration after the storage within the storage tank. This leads to lot of drawbacks and caters the poor or bad quality of water.

ACT WISY introduces the pre-filtration before the storage and performs fine filtration very effectively and efficiently. The harvested rain water from the roof area may have some debris like leaves, mosses and tiny particles which are adhere with the roof surface. Before storage, should have to pre-filter the rainwater from this debris. Otherwise, it causes severe health hazards.

By ACT WISY rainwater harvesting Systems, the rainwater coming from the roof through the downpipe / downspout is drawn sideward through the vertically orientated stainless steel filter insert by adhesion forces and natural flow of water. Filtered water falls into the collecting space and is fed via the outlet connection to the storage tank. The remaining water along with leaves, insects, etc. is washed through the uniquely constructed vertical filter by self-cleaning action.

ACT WISY have two types of fine filters.

1. 1Downpipe filter collectors (Downpipe Garden collector filter- GRS & Filter Collector- FS).
2. Vortex Fine Filter (WFF 100, WFF 150 & WFF 300).

Both filters have self cleaning capability to separate the suspended solids from rainwater. Also performs oxygenation along with the fine filtration.
