WASTE WATER TREATMENT FACILITY

CSC Waste Water Treatment Project

Customer Need

The client needed a waste treatment control system to treat all lab waste generated at the facility prior to discharge into the sanitary waste system.

Custom Systems and Controls was asked to design and build an automated system to effectively perform with the following design specifications:

  • Flow 60 g.p.m.
  • Discharge when pH is 5.5 - 9.0
  • Tank capacity minimum 200 gallons
  • Manual interface with treatment process

Solution

The waste treatment system controls the neutralization of the waste material, verifies pH levels within the tank, controls the removal of neutralized material and initiates an alarm if pH falls outside the specified range.

Some features of this project are:

  • 280 Gallon polypropylene tank
  • 3" PVC input/output connection
  • 2 Pumps
  • 1 Mixer
  • 4 Floats (Low, Mid, High, Alarm)

System Components

Mitsubishi PLC

Mitsubishi Operator Interface

Aromat Contactor

Allen-Bradley Components

Success

The client is able to successfully discharge its waste into the waste system while meeting the town's guidelines. This unit has been in operation for over 17 years with no major repairs and is still treating water for the client.
