Potato chip, or call the Potato Starch Foods factory wastewater treatment systems, potatoes must be peeled, sliced, destoned, and washed, processes that require a significant amount of water. according to the mixture wastewater sampling analysis test report, potato wastewater very special, it’s has the high COD, BOD, High TSS.
NO. | Item | unit | Value |
1 | PH | — | 4.8 |
2 | CODcr | mg/L | ≤15300 |
3 | BOD5 | mg/L | ≤8000 |
4 | SS | mg/L | ≤4000 |
5 | NH4-N | mg/L | ≤219 |
N (total) | mg/L | ≤38 | |
P | mg/L | ≤12.5 |
The waters resulted at potatoes washing for chips, snacks or fries production are valuable wastes, which contain organic compounds as proteins (around 0.7%) and starch (around 1.66%)
Potato Wastewater Treatment Processing
Potato Wastewater——Bar Screening——Equalization Tank——DAF System——Anaerobic Tank——Anoxic Tank——Aerobic Tank——MBR Tank——Clean Water Tank
use processes like filtration, sedimentation, and biological treatment to remove contaminants. The treated water can then be safely released into the environment or reused within the facility
During Potato Chips manufacturing, first step the rotary bar screen is installed at the inlet of pump station or water treatment system, with the purpose of removal the particle waste like peeling skin of potato, bad potato or any garbage or plastic waste, big solid and suspended.
- Flocuulation and coagulation
Dosing the PAC /PAM/ , high efficiency removing and lowdonw the COD/BOD5 /suspended solids by the DAF System
- pflow anaerobic reactor
Anaerobic reactor, uses internal settling and gas collection units, followed by aerobic treatment.
Biogas reactors and Aerobic treatment
Can digest up to 90% of organic pollution and produce biogas.
- Membrane Bioreactor
MBR separates the clean water from the wastewater, MBR membrane has very small pore sizes that are ranging from 0.04 – 0.4 microns. The MBR process combines triggered sludge treatment with the membrane for liquid-solid separation. When MBR can attain almost complete separation of the suspended solids & dramatic reduction in the contaminants..
Benefits of MBR treatment in Potato factory
- Reduces eco footprint: Treatment systems can reduce the environmental impact of potato chip manufacturing.
- Reuses water: Treated water can be reused for cleaning and cooling.
- Recovers sludge: Digested sludge can be dewatered and used as a soil conditioner.
