The
2" Sand Separator battery is a modular system that
separates sand from the water and collects the sand
at the bottom of the system, ready to be drained.
See explanation of the sand separation process.
Sand Separator Batteries may be built with
manual (or automatic) disc filter units that filtrate
the residual sand particles and other solid impurities
from the water.
The inlet of each filter unit is connected to the
outlet of one of the sand separators and completes
it's operation. Each filter unit has one filtration
element composed of a stack of grooved discs.
See the explanation of Disc
Filtration Technology.
The
number of sand separators in the battery can range
between 1 to 24, depending on the application requirements,
such as the flow rate.
One sand separator unit is designed for approx; mately
20 m3/hr. Each sand separator my be isolated
from the battery by 3 manual valves, which permits
changing the number of functioning units if the flow
rate is changed.
The 2" Sand Separator battery continuously supplies
clean water to the downstream, and does not require
any manual interference.
The concentrated sandy water should be flushed from
time to time, depending on the load of sand in the
water. On batteries that include manual filters, the
filters should be manually cleaned, any time when
the filters are loaded with solid impurities.
This situation can be determined when the pressure
gauge shows a large difference of pressure between
the inlet and outlet of the battery.
Each Sand Separator and filter are isolated from the
battery with 3 manual valves, which may be closed
during the manual filter cleaning, eliminating the
need to stop the work of the battery and the supply
of filtered water.
Process of Sand Separation Raw water tangentially
flows into the 2" Sand Separator.
The tangential flow causes centrifugal forces, which
in turn cause separation of the heavy sand particles
from the water, throwing the sand particles toward
the walls of the Sand Separator, where the particles
settle down to the drain.
The clean water then flows up through the outlet port
for use.
