In its simplest form the Component Cleaning Process & “Closed Loop” Water Recovery/Recycle System consists of the following operations:
1. Components are cleaned & undercut if necessary to relieve glass to metal seal stress points.
2. Components are put through an “anti-tarnish” rinse and dried in centrifuges.
3. The water is then treated for Conductivity, pH levels and neutralized.
4. Suspended matter is removed by filtration.
Wash Line Process: Components are loaded into holders, trays or fixtures, as required. They are immersed and agitated in a series of wash/cleaning tanks:
Note: The process may change depending on individual requirements and the actual Procedure is component specific.
Water Treatment Process: PPM levels (parts per million conductivity) and pH levels are monitored, recorded and treated at each stage of the process.
All the wash line solutions drain into a sump holding tank. At this stage the solution is acidic and contains dissolved solids.
The solution is pumped to a series of treatment tanks prior to discharge:
- Brine Tank: This tank holds backwash water from the DI units along with wash line and tank sweepings.
- Neutralization Tank: This tank has a recording pH meter and probe installation connected to a pulsating pumping station, which releases a sodium hydroxide (caustic) solution into the tank on demand.
- DE Filtration Tank: Stores the solution from the Neutralization Tank. Attached to this Tank are a pumping station and two filters. The filters are coated with diatomaceous earth, through which the water is pumped for fine filtering.
- Holding Tank: This tank is where any final pH adjustments are made to make sure the water is neutral (7.0 – 7.5pH) and within all limits/guidelines of our Discharge License prior to release.
