FOOD PROCESSING WASTEWATER TREATMENT

► Characteristics of water source

- Wastewater from plant operations is characterized by high suspended substances, many surfactants, high organic matter content, etc

- Wastewater has bad smell, high viscosity, and is easy to foam when handling.

- In particular, with the concentrated amount of wastewater from food processing at the cafeteria containing suspended and dissolved grease.

- There are 02 main types of wastewater generated from the plants operations:

+ Gray water is water generated from washing floors, washing tools, waste water from food processing

+ Black water is more polluting than gray water due to arising from the toilets and toilets.

► Requirements for food processing wastewater treatment

Numerical order	Targets	Unit	QCVN 40:2011 /BTNMT
1	pH	–	5.5 – 9
2	BOD₅	mg/l	50
3	COD	mg/l	150
4	TSS	mg/l	100
5	Total Nitrogen	mg/l	40
6	Amoni	mg/l	10
7	Total Phosphorus	mg/l	6
8	Coliform	MPN/100ml	5.000

► Wastewater treatment process

- Wastewater pressure is flowed into the trash rack to remove large-sized garbage

- Wastewater flows into collection tanks and into grease separating tanks.

- Water after separating the vegetarian grease to the conditioning tank. Air conditioning tank is responsible for stabilizing the flow to ensure the HT handles the correct capacity, and at the same time arranging a gas distribution system, the air blower will supply air to the tank to help wastewater always be stable in the concentration of the cell. contamination in water.

- In the biological tank, anaerobic microorganisms will decompose organic substances in wastewater into inorganic substances in simple form and Biogas gas (CO2, CH4, H2S, NH3, etc) to reduce nitrogen and phosphorus. present in wastewater.

- The BOD content of wastewater s significantly after the biodegradation process.

- Water flows into the disinfection tank. Microorganisms are destroyed by chlorine.

- Finally, wastewater is pumped into the pressure filter to remove residual residue content that the settling process has not performed yet, creating the necessary transparency before entering the receiving source.
