How
PopUp filter works?
The “PopUp
Filter” has three components (rainwater receptor, flush valve and filter
element). Rainwater receptor is where the rainwater is allowed to flow from
down pipes in to the filter and a flush valve is provided to flush the first
flow of the rainwater along with leaves, dust etc. Water received in the receptor flows upwards
against gravity through a filter element to filter most of the floating
elements and allow water to stabilize in this filtration zone. Rainwater passing through this filter element
is relatively cleaner and flows out through an outlet, which can be led to
storage device.
Filter element
is mounted on a vertical stabilizer barrel with a friction fit. Filter element
need to be cleaned periodically during the rainy season to remove the
impurities trapped and there by keep the filtration system clean. In the event filter is not cleaned and the
filter element is getting clogged, “PopUp Filter” has a safety feature built
into it. The water pressure pushes out
the clogged filter element from the stabilizer barrel and allows the water to
flow out freely. This safety feature
will avoid flooding of the rooftop because of clogged filter. The first indication of the filter getting
clogged is rainwater flowing out of a vent hole provided on the top of the
filter element.
PopUp
Filter Maintenance:
Flush the first rainwater by opening the
flush valve on the filter for few minutes, close the flush valve after all the
dirt on the roof is flushed. When the rain stops, flush the filter and remove
the filter cartridge gently from its place and wash it thoroughly under a
running tap by gently tapping the filter element with a stick on all
sides.
The dirt sticking in the filter element
gets released and washes off. Replace
the clean filter element back to its place by gently inserting it in the
barrel. Take care not to press it too
hard at the end. If pressed too hard,
filter element gets locked inside the barrel and may require greater force to
retrieve it back when required for cleaning and also may not PopUp when the
filter is clogged or chocked. Allow the
filtered water to get stored in tank for future use.
