Rainwater Harvesting Kit (C) – 800m² Roof Area – the ideal accompaniment to the Enduramaxx Rainwater Harvesting Water Tank range. The rainwater filter system is designed for roof spaces up to a maximum of 800m² (per kit) and contains the following;
- Twin Rainwater Filter unit
- Siphon overflow tube
- Calmed inlet (pipe to go from the bottom of the filter to the bottom of the tank)
Water is equally distributed across the cascade where cleaning occurs, with the largest dirt particles forced across the primary filter cascade directly to the sewer.
Next, pre-filtered water then flows over the secondary filter sieve (mesh size 0.65 mm) where the mesh structure washes any remaining dirt into the sewer. Cleaned water flows into the tank via a calmed inlet, designed to undertake a secondary cleaning step by allowing the water to enter the tank with minimal turbulence. This ensures it does not disturb any sediment which may be present at the bottom of the tank.
Calmed rainwater entering the tank supplies oxygen to the water resting at the lower end of the tank, keeping it fresh by prevention of anaerobic decomposition. Finally the overflow siphon, which incorporates a skimming inlet, skims the surface water inside of the storage tank. This removes further debris, oils and other floating contaminants thereby increasing the quality of the stored water.
The filter kit is suitable for garden watering as well as a large range of other uses and helps to retain as much collected water as possible, whilst providing an efficient filtration system and regular replenishment of stored water.
