1. Pre-Tank Filtration:
During the first step of the filtration process, up to 90% of rainwater is filtered & diverted to the rainwater tank. The remaining 10% are used
to ensure the self-cleaning effect of the filter. WISY filters operate as a first flush device, directing leaves, dirt & debris to drainage or
On-Site Detection Tank (OSD). Therefore, large particulates are removed. Due to the oxygenation of the water during the filteration process,
the amount of harmful bacteria in the rainwater tank is greatly reduced.
2. Smoothed Inlet and Distribution:
The smoothing inlet prevents incoming water from stirring up in the tank, distributes it smoothly and oxygenates the filtered rainwater.
3. Floating Suction Filter:
The floating suction filter ensures the intake of the cleanest water from just below the water surface.
4. Multisiphon Overflow:
By skimming floating particulates on the surface of the water, the Multisiphon prevents the formation of a surface barrier layer & ensures an
optimum exchange of oxygen between air and water.
