How a hydrocyclone works
A hydrocyclone is a conical vessel that water enters tangentially and spins in. Centrifugal force drives heavy particles such as sand to the wall, and they fall to the bottom of the cone into a collection tank; cleaner water leaves from the top. It has no screen or discs, so sand cannot clog it.
A hydrocyclone removes only heavy particles and does not catch organic matter or algae. That is why it is usually fitted at the start of the filtration station, before the disc or screen filter, to reduce their load, especially on wells with sandy water.
Sizes and choosing
Our rows cover hydrocyclones in 1, 1-1/2, 2, 3, 4, 6 and 8 inch. Each unit is built for a flow range, and outside that range separation is poor; so choose the size by the pump flow.
In your enquiry give the pump flow, inlet size and how much sand the water carries. The collection tank must be emptied regularly. Add the disc or screen filter that follows the hydrocyclone to the same list.
Emptying the tank and maintenance
Separated sand collects in the tank under the hydrocyclone, and if the tank fills, the sand re-enters the flow. So open the tank drain valve regularly; with very sandy water, daily draining is needed. Install the hydrocyclone vertically on a firm stand with pressure gauges before and after it.
If the pump flow changes, for example when the pump is replaced or the well changes, the hydrocyclone's efficiency changes too; in that case check its size again.
