Installing ACT-WISY at Safalyam Complex

ACT-WISY successfully installed modern rainwater harvesting systems at Safalyam Complex, Palayam, Thiruvananthapuram Development Authority (TRIDA). The project was proposed to Mr Venugopal, Chairman, TRIDA. The TRIDA team members were Anil Kumar, Secretary TRIDA; Promod Kumar, EE and Hari Prasad, AE.
Before installationSafalyam Complex had no rainwater harvesting systems. There was a sump of having 350 cu. metres water storage capacities. Water source was tanker water and government supply. Rain water was not collected and during rainy seasons the landscape and the parking lot had a lot of water collections and a kind of flood or water filling happened.
The 5,000-sq.-feet catchment area had selected. The rain in such area used to go to the drain or sewage of improper water management.• Drain related issues• No filtration systems for rain water• Accumulation of dirt in the sump.
After the installationACT-WISY recommended WFF 150 Vortex Filter for the filtration of rainwater at the Safalyam Complex.
The WFF 150 Vortex Filter is for medium commercial or large residential applications and provides the highest quality of rainwater. The vertical design, the force of adhesion and the principle of free flow do the self-cleaning of the filter. Debris is discharged from the filter along with “first flush” and excess water necessary to carry debris to sewage. The filter provides the highest quality of stored rainwater with minimal maintenance.
Vortex filtration system has vertical cylindrical type of filter. The filtered water will be collected to the storage tank using an extended pipe down to the bottom of the tank fitted with a smoothing inlet to accelerate the sedimentation process and to develop a bio film. Simultaneously, a process of oxygenation is accelerated in the filtration unit which helps to filtered rainwater to stay for a longer duration. This results in high efficiency and long-servile life, i.e. high water yield and good cleaning performance. ACT-WISY rainwater harvesting systems strictly follows the clear guidelines of DIN 1989 for rainwater technology in Germany.
How the filter works?The WFF 150 Filter can filter rainwater to 280 microns from a collection area up to 5,000 square feet. The rainwater from the roof enters the inlet connection in the side of the WFF through a horizontal drainpipe, spreading over the cylinder-shaped filter mesh. The inlet is designed to swirl the water in a vortex-like action around the surface of the stainless steel filter. The rainwater is drawn through the vertical mesh walls of the fine filter by adhesion, then collected and fed through the outlet to the storage tank (sump). Debris and particles too large for the filter are flushed through to the drain outlet by the action of water flowing down the surface of the filter.
More than 95 per cent of the rainwater entering the WFF is filtered and collected by this principle. The ACT-WISY WFF 150 Vortex Filter should be inspected two or three times a year to ensure the natural flow of water in the filter is not obstructed. The stainless steel filter only needs to be cleaned once a year in a dishwasher or by hand washing. Depending on the debris filtered, an additional cleaning may be necessary to maximise efficiency.
