Hydrocyclone and method to remove particles from liquid streams

A method of separating particles from a liquid stream and irrigating plants comprising:

• creating a hydrocyclone having an inlet, a separation section, a clean liquid outlet, and a slurry outlet, wherein the separation section has a vortex having a length and a cone having a length, and wherein the vortex length is longer than the cone length;
• wherein the vortex has a vortex arm having a length and a vortex base having a length, and wherein the ratio of the arm length to the base length is between about 2 and about 4;
• creating a pressure within the separation section;
• directing the stream of liquid containing particles into the inlet;
• ensuring the liquid stream is circulated through the separation section, wherein the liquid stream is separated into a clean stream and a slurry stream by the pressure;
• guiding the clean stream out of the clean liquid outlet, wherein the clean liquid outlet is connected to an irrigation dripline and the clean liquid is delivered to the dripline and to drip streams to irrigate plants;
• and
• disposing the slurry stream out of the slurry outlet, wherein the slurry outlet is connected to an emitter which removes the slurry stream as a continuous purging flow effective to create back pressure in the hydrocyclone thereby inhibiting clogging of the dripline during usage.
