Rainy Filters

“Rainy” Dual Intensity self-cleaning Rooftop Rainwater Harvesting Filters

The down take pipes from the roof to be interconnected and lead till the Filter unit and to be connected to the Inlet of the Rainy Filter

Function of the Filter

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.

Special Features

The Rainy filter has open drain outlet in order to avoid stagnation of water and dirt particles inside the Filters
No consumables required
Filter inlet and outlet connections can be rotated 360 degrees to suit to the pipe line direction.
Bypass valve is provided in the filter to divert the sudden summer rains into the drain
The filter efficiency remains unchanged even with the variation of intensity of rainfall
Fully enclosed and compact in size, so minimum space is sufficient to install
The versatility of these filters is such that they can even be fitted inside the ducts.
Tough high density UV treated High density polyethylene Housing is built to last long
filter element is made out of SS-304 Steel and it is food graded
The Filter being wall mounting can be fitted with wall bracket and flexible rubber straps with hooks
Inlet, outlet and drain outlets can be connected easily through the rubber bushes and bellows to the existing pipes.
Various models are available to suit various dimension of Roof areas as per the requirements of consumers
Since the filters do not have any moving parts, there is no wear & tear of the filter hence it enables long life span
Due to simplicity in connection, local plumbers, technicians, can easily install the filter
The technology of filter components is of food grade, environment friendly, and recyclable
If the filter element is clogged it can be easily removed , washed and Re-inserted

Advantages

By storing of water in the sump & reutilizing, around 35% of the annual requirement of a household can be met. Thereby a considerable amount on the water and power bill can be saved.
Dependency on water tankers, ground water and corporation water can also be much reduced
Recharge of Groundwater, replenishes the deeper layers of the earth’s crust which in turn insulates the earth from rise in temperature, reducing global warming
Reduces loss of top soil, surface runoff , thereby avoids silting of ponds and lakes
Reduces hardness , salinity and TDS contents in the bore well
Seawater ingression can be checked in costal line
All materials used in this Technology are eco-friendly and recyclable
Reduces significant carbon foot prints
- Technology works on the Gravitational Principle
- Reducing the Pumping of water from distant places , deeper depths & Movement of Water Tankers
Checks overexploitation of groundwater source.
Prevents water logging in low lying areas.
