Design Background:
Input water quality: The range of food products presents different wastewater challenges. Examples include fruits and vegetables for canning and preserving, fish, meat and poultry, dairy products, and fats and oils. This Equipment is for Bread and Cake Food factory wastewater or equivalent, it is also among the most difficult and costly waste to manage because food processing wastewater can contain large quantities of nutrients, organic carbon, nitrogenous organics, inorganics, suspended and dissolved solids, and it has high biochemical and chemical oxygen demands, the capacity will be 100m3/Day, 24hours working per day.
Output Water quality: meet the discharge standard and can use for toilet flushing, gardening.
S. N Item Input Water Discharge Standard 1 CODCr COD≤6000mg/L ≤150 mg/L 2 BOD5 BOD5≤4000mg/L ≤30mg/L 3 SS ≤321mg/L ≤20mg/L 4 NH3-N ≤50mg/L ≤10mg/L 5 Oil grease ≤100mg/L ≤5mg/L 3. How is the wastewater treatment Process in food processing:
Wastewater——Bar Screening and oil grease remove /—Anaerobic Tank—Aerobic Tank (MBBR)——Sediment tank—Anaerobic Tank—Aerobic Tank (MBBR) ——MBR Tank <MBR Membrane > ——Clean Water Tank ——Control Room
4. Dissolved air flotation
It is one of the most effective methods whose specific gravity is close to 1.0 from water. Dissolved Air Flotation is liquid/solid or liquid/liquid separation process to remove tiny, suspended solids that density close to the water, colloid, oil and grease etc.
DAF dissolved air flotation consists of flotation tank, dissolved air system, reflux pipe, dissolved air released system, skimmer (Based on customer needs, there are combined type, traveling type and chain-plate type to choose.), electric cabinet and so on
Four comprehensive technologies：
- Micro bubble generating technology；
- Subsurface capture technology；
- Technology of automatic slagging controlled by liquid level；
- Non-clogging releasing technology with high efficiency；
Product Description Application Fields:
- Oil-water separation of wastewater in petrochemical industry and so on (including emulsified oil and vegetable oil)；
- Pretreatment of wastewater in the industries of textile, dyeing, bleaching, wool spinning；
- Wastewater treatment in surface treatment industry (such as galvanization, PCB, pickling)；
- Pretreatment of wastewater in industries of pharmacy manufacturer, chemical production line, papermaking, tannery, slaughterhouse, food-making factory and so on；
- As a replacement of sedimentation tank, the flotation is widely applied in industrial wastewater pretreatment。
5. The Packaged MBR System in containerized included:
Anaerobic biological treatment which the digestion is a sequence of processes by which microorganisms break down biodegradable material in the absence of oxygen, There are four key stages of anaerobic digestion involve hydrolysis, acidogenesis, acetogenesis and methanogenesis, and the main function is removed the Nitrogen and bacteria, that will help down the BOD.
Aeration biological, the process involves air or oxygen being introduced into a mixture of screened, and primary treated sewage or industrial wastewater (wastewater) combined with organisms to develop a biological flock which reduces the organic content of the sewage. The main function is removing the nitrifying bacteria and phosphorus bacteria, and break down the COD& BOD
MBR clarification is separating the clean water from the sewage.
