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 approximately 20 m3/hr. Each sand separator can 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 Separators. 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.
