ACT WISY 4 STEP RAINWATER HARVESTING SYSTEMS

AN INNOVATIVE IDEAS OF MODERN RAINWATER HARVESTING SYSTEMS - ACT WISY

ACT-WISY is an Indo - German trade name for the “Emerging / Modern technologies of Rainwater Harvesting Systems” as a total concept of water management for domestic and industrial applications.  We are introducing Rainwater Harvesting Filtration Systems in collaboration with WISY AG, German entity for RWHS over the last 25 years.

ACT-WISY 4 STEP RAINWATER HARVESTING FILTRATION METHODOLOGIES:

ACT-WISY’s filtration system works based on vertical and cylindrical type of filter with adhesion principle adopting the theory of natural flow of water. It has an automatic system of rinsing/cleaning by using 3 to 15 % of rainwater harvested. The filtered water will be collected to one side of the chamber and send to storage. The filtered water in the storage tank undergoes different stages of oxygenation to maintaining the water quality for longer storage duration. The rinsing/dirt water shall be sent to drain out or sewage.

Step 1: Filtration of rainwater by Down pipe filter or Vortex filter along with the oxygenation.

Harvested rainwater should be filtered and aerated before entering to the tank for storage. Filtration remove the debris and particles larger than 0.28 mm and are flushed out to the drain outlet or sewage.  ACT-WISY pre-tank filters can accomplishes  removal of the suspended solids along with oxygenation of the water, both of these task can assures the water quality in the tank for longer storage duration.

Step 2: Acceleration of sedimentation and distribution of oxygenated rainwater within the storage or open well.

This device is beneficial for the tank and may remove additional sediment from the water. The ACT-WISY smoothing inlet calms rainwater as it enters the storage tank to prevent the agitation of sediment at the rainwater inlet. The smoothing inlet also helps to aerate the harvested rainwater by directing the rainwater in upward and outward, avoiding any disruption of the water in the base of the tank and preserving water quality in the tank.

Step 3: Extraction of filtered water from the storage by a Floating filter.

For re-use, the water is extracted from the tank (10-15 cm from the top surface of water) by Floating Suction Filter, which ensures that the water taken is most oxygen enriched.

Step 4: Overflow control, skimming of floating substances.

To prevent the back flow to the storage during heavy rains, the storage tank includes an overflow protection device, called Multisiphon.
