Rainy filters for Rain water harvesting


`RAINY’ First of its kind Dual Intensity Rainwater Harvesting Filters with self cleaning and auto flush out arrangements.

‘RAINY’R Dual Intensity Rainwater Harvesting Filter™ is the result of over 10 years Continuous R&D done by the team of FARMLAND RAINWATER HARVESTING SYSTEM, by studying the pattern of rain fall in rural and urban India, intensity of rainfall, type of houses, pipeline used for rainwater outlets, re utilization, recharging of ground water and Tube well etc. In the past decade we have witnessed phenomenal changes in global weather patterns. The unpredictable and erratic weather patterns have resulted in torrential down pours and rainfalls of very high intensity. These heavy duty Dual Intensity Rainwater Harvesting filters are so designed; keeping in mind the capture of rainfall loads varying from 5mm to 75mm/hour without affecting the efficiency of filter and the operating required less than 0.06 kg/cm2 (2 feet) so the filter can perform even in low Roof areas. The design, stability and filter function efficiency is directly proportional to the intensity of rainfall. Different models of filters were set in place to capture rainwater from varied rooftops. This brought in affordability, to all cross sections of households and Industry.

Rainy filters are designed with self cleaning mechanism and can be fixed to the wall by connecting Rooftop rainwater drain pipes. The rainwater along with dirt particles enters into the inlet of filter through the hollow pipe tangentially to the filter housing and rotating slowly along the periphery of upper housing so as to flow into the SS 304 filter element placed in lower housing of the filter unit in angular motion at specific velocity, which creates cohesive force and segregates dirt particles and clean water individually. However when the intensity of rainfall increases the high volume of water moves in circular motion with high velocity in the upper housing and creates a centrifugal force. In both situations, involving low and high intensity of rainfall , the working principle of the filter based on cohesive and centrifugal force respectively, aids the filter element to divert clean water into the cistern/ recharging well and simultaneously flushes out automatically sand, debris, and dirt particles through the drain outlet.
