ROOFWATER FILTER

Rainwater collected directly is very pure and clean. However, rainwater collected from the rooftop of any building may contain many substances, which get mixed with pure water on the roof (leaves, bird droppings, dust etc.). These impurities need to be filtered before the rainwater is stored. 'Roofwater Filter' is a simple device, which is very effective and user friendly.to filter rainwater from the roof. The construction and functioning of this device is briefly represented in Fig - 1 (attached). An important feature in filtering rainwater is that this equipment automatically allows separation of initial rainwater which has large quantity of contaminants from rooftop (referred to as 'auto flush valve') from relatively cleaner and purer rainwater subsequently collected. The filter cartridge has a backwash arrangement to clean the filter cartridge without taking out the filter cartridge away from. the equipment. It also has built in safety arrangement to release the water in the event of clogging of the filter without causing any flooding on the rooftop and also without damaging the equipment. These three features are incorporated in the designing of the Roofwater Filter itself.
