Section 4: System Maintenance
4.1 Garnet Removal System Daily Check List
Warning
Always disconnect power and relive pressure from the system before performing any
maintenance on this filtration system.
Caution
Always follow correct lock out procedures when working on this filtration system.
Warning
Failure to keep suction above − 10 in/hg could result in catastrophic pump failure.
1. Make sure suction basket is serviced (empty).
2. Open all gate valves.
3. Start filtration system.
4. Check suction basket pressure gauge. At start up this should read approximately − 3 in.hg – service
basket before the suction vacuum gauge reads − 10 in.hg.
5. Check inlet and outlet gauges on top of separator. These pressure readings should be approximately
35 psi on the inlet gauge and approximately 26 psi on the outlet gauge. Separator must run between
4 and 12 psid.
Warning
This garnet removal separator must run between these pressure differentials. If the system does
not maintain the proper differential pressure it will affect the garnet removals performance and can cause
premature pump maintenance/failure.
6. Service hopper as needed.
7. In front of the eductors there will be no garnet accumulation, however there maybe some quite areas
in the tank where garnet may collect. The garnet "pile" should not be allowed to exceed 6" in height.
Monthly checking of garnet build up on the tank bottom is advised, using a stick tap on the tank
bottom in various locations. Any garnet accumulation will show up on the stick and it can be easily
removed.
