RECOMMENDATIONS

Operational Control Recommendations:

·      Assign prime operator to be responsible for all shifts with authorization to make decisions concerning waste treatment.

·      Set up and maintain a clean operation log book along the same lines that you are now using except revise to suit your needs.

·      Set up mandatory check times, as required, with specific points to monitor and record, along with comments section for each shift.

·      Monitor rinse water flows to insure that flow into equalization sump does not exceed flow design. High level alarm in equalization sump keeps alarm light continuously illuminated. This may cause another more serious alarm to go unnoticed.

·      Answer alarm conditions immediately and correct as soon as possible.

·      Monitor System

·      Jar Testing

·      Sample Collection

MONITOR SYSTEM

·      Hourly

·      Per shift

·      Bi-weekly

·      Weekly

·      As required

Hourly:

·      Instrumentation

·      Water quality

·      Flocculator performance

·      Condition and color of N1-N2-Floc

·      Sludge level in thickener

·      Filter press performance

     A.     Estimate emptying time

·      Refill as required or estimate time to refill of all reagents.

Once per shift:

·      Record flow reading

·      Check pump performance

·      Record treatment performance

Bi-weekly:

·      Clean and calibrate probes to instrumentation

     A.     Known buffer solution for pH - calibrate

     B.     ORP meter - calibrate

·      Verify instrumentation setpoints during calibration

Weekly:

Clean filter press cloths weekly or sooner, as required.

Summarize all reports and inform all shift supervisors of any conditions out of the ordinary.

Note: These recommendations are only minimum checks. Other checks may be required as determined by operating personnel.

As required:

·      Jar testing

·      Record alarm condition reason and corrective action taken

·      Record preventive maintenance or maintenance repairs

·      Spot test grab samples and record results

     A.     pH

     B.     Specific metals (Chrome, Iron, Nickel, etc. test kits)

     C.     Bleach excess (Cyanide systems)

     D.     Color

     E.     Suspended solids condition
