4. Initial Installation & Operation
General
Based on the centrifuge principle, the particles are spun against the outside wall of the
Hydrocyclone and gravitate towards the bottom into the Sedimentation Tank. The velocity at
which the water flows through the Hydrocyclone determines the efficiency at which the
particles are separated from the water.
• Normal working conditions are achieved when headloss on the Hydrocyclone is not less
than 3 psi with a recommended range of 3-8 psi.
−A headloss of less than 3 psi will reduce the separation efficiency and a headloss of more
than
8 psi might induce increased erosion.
• The Hydrocyclone is designed for a maximum recommended working pressure of 120 psi
and should not exceed 145 psi.
Installation
•
Install and connect the Hydrocyclone vertically with the Sedimentation Tank underneath
the Hydrocyclone.
•
Special attention must be given to the correct flow direction: horizontal inlet and top
vertical outlet are clearly marked by arrows.
•
Install the manual ball valve to the flush port of the Sedimentation Tank.
•
Check that the actual flow rate through the Hydrocyclone is within the recommended
range. Inadequate flow rate will result in reduced performance.
•
If more than one Hydrocyclone is installed, leave sufficient space between units to
facilitate maintenance.
•
A quick acting pressure relief valve must be installed upstream of the Hydrocyclone if the
pressure is not controlled effectively.
INSTALLATION WITH OPTIONAL AUTOMATIC FLUSHING KIT
•
Automatic Flushing Kit includes an electric Gate valve, controller and small command
filter.
•
Install the electric Gate valve on the outlet opening of the Sedimentation Tank.
•
Connect the controller to the electric Gate valve.
•
Insert the batteries inside the controller (or plug in for AC) and close the cover tightly.
•
Adjust the controller as follows:
•
Flushing time for Sedimentation Tanks with 0.4-16 gallons: 15-20 seconds
•
Flushing time for Sedimentation Tanks with 32-60 gallons: 30-40 seconds
•
Time between flushing: 30-120 minutes
•
If the water contains high loads of dirt, shorten the time between flushing
