Wastewater Treatment for Food Production
Food production often has uneven wastewater with high BOD, COD, fats, proteins, detergents and pH fluctuations. Such tasks require a stable process scheme.
Typical Problems
- fats, proteins and organics
- high BOD and COD
- uneven flow
- odor and biological overload risk
Typical Process Scheme
1
screening or mechanical pretreatment
2
equalization and pH correction
3
coagulation, flocculation and DAF flotation
4
MBBR/MBR biological treatment and polishing
Solutions We Apply
1
equalization and pH correction
2
DAF flotation
3
MBR or MBBR biological treatment
4
polishing, disinfection and reuse
Equipment
- equalization tanks
- DAF flotation unit
- coagulant and flocculant dosing
- MBR/MBBR blocks
- filters and disinfection
What Affects Cost
- daily flow and peak discharges
- BOD, COD, fats and suspended solids
- production operating mode
- required treated water quality
Data Needed for Calculation
For calculation, we need flow rate, operating mode, water analysis or wastewater composition, treated water requirements and equipment placement conditions.
