Potato peel

Challenge

  1. Potato peel has been consider as a suspended matter, where as this being a composite is either a SSora floating impurity.
  2. Complied TN & TP for final discharge.
  3. Permeate Extraction quantity is not as per requirement. Quality is a concern and operation is by in large manual.

 

Assessment Condition

The plant has been modified in 3 phases to so it appears disorganized in layout but is able to deliver the results.

The plant has been modified in 3 phases to so it appears disorganized in layout but is able to deliver the results.

The facility is yet to profit from the investment made in new facilities UAS Band MBR etc. and we should conclude to commission them soonest. As soon as these units are fully operational, WWTP will have some spare capacity in trickling filter and Secondary clarifier to manage the accidental higher loads more comfortably. An added plus is availability of standby unit for any disturbance in existing plant.

 

Assessment Condition

MBR system needs major modification as it shall be designed for full auto operation including the membrane degasification. The modification in system is needed as the current manual intervention in operation will involve ignorance and membrane fouling.

he overall scheme needs modification with proper piping and pumping to bring Equalization Tank as the first unit after Parabolic Screen but before Primary Clarifier. Further, the FOG removal shall be done after Primary clarifier in an API separator. This is an important investment to make as delaying it may complicate the problems.

For future designs, special attention needs to be given to Potato Peal. It’s not Suspended Solids. It’s a complex composite of Skin & Pulp and can SINK, Float or remain Suspended depending upon its composition. If it reaches UASB bugs will preferable eat the pulp partand naked skin would just float and be available in treated water causing problems to MBR. Even for this project we have recommended for Auto Self Cleaning Filters post Primary Clarifiers to arrest the fine peals.
