Filtration and Water Treatment
Sand Separator Batteries
Size : 2" sand separator Batteries
3" - 10 " inlet / outlet manifold diameter
Capacity : Modular for different flow rates. ( about
20 cu.m / hr per unit )
Operation : Automatic sand separation with optional
built - in backup disc filtration.
Application : Used in field crops, orchards and groves.
Standard Features:
High effciency of sand separation
Long - term operation with little maintenance.
Self operating - maintenance close to zero
Corrosion resistant.
Continuous flow during backflush
Special Features:
Isolation valve allow for :
1.Maximum flexibility of flow rates with maximum separation effciency.
2.Continuous flow during individual unit maintenance.
Special design prevents erosion damages caused by the high velocity of sandy water flow.
The 2" Sand Separator battery battery is a modular system that separates sand from
the water and collects the sand at the bottm of the system, ready to be drained.
See explanation of the sand separation 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 Tecnology
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 cu.m / 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 in changed.
The 2" Sand Separator bttery continuously supplies clean water to the
downstream, and does not require any manual interfernce.
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 particle from thw 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.
