Introduction: 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.
