How to treat wastewater in Chicken meat processing industry?
Water is used extensively in the meat processing business to wash the corpses of cattle, sheep, chickens, etc. Water is also utilized to sanitize and completely clean all of the facility's process equipment. Every killing and processing shift at the factory must be followed by a thorough cleaning and sanitation procedure, according to federal standards.
In most cases, the cleaning procedure consumes far more water than the actual meat processing. The creation of wastewater might be irregular due to the interval between shifts and the processing and cleaning steps.
Treatment is a necessity
Wastewater from all forms of meat processing has a similar composition. They each have significant amounts of TSS, FOG, and BOD, making them difficult for a municipal treatment plant to handle when it already has a lot of other customer flows to deal with. Because the downstream municipal plant cannot readily foresee and plan for high-load flows, the inconsistency of meat and poultry processing plant flows exacerbates the problem.
Typical measured levels of major contaminants in wastewater-
COD (Chemical Oxygen Demand) – 4,500-12,000 mg/L
BOD (Biological Oxygen Demand) – 2,500-8,000mg/L
TSS (Total Suspended Solids) – 600-4,500mg/L
FOG (Fats, Oil and Grease) – 100-2,000mg/L
Effluent – Required characteristics
Typical required content level limits of major contaminants in treated wastewater-
COD (Chemical Oxygen Demand) – 500 – 1,000 mg/L
BOD (Biological Oxygen Demand) – 250 – 500 mg/L
TSS (Total Suspended Solids) – 250 mg/L
FOG (Fats, Oil & Grease) – 100 mg/L
Because municipal treatment plants are incapable of eliminating the pollutant concentration characteristics of such kind of Industrial wastewater, pretreatment of wastewater from a meat and poultry processing facility is required before discharge to a municipal sewage system. A pretreatment procedure is required, with the goal of decreasing pollutants that result in surcharges in this scenario. TSS, FOG, and BOD must be removed from meat processors.
Step 1: Pre-treatment systems
Pre-treatment eliminates readily collected items from raw wastewater before they harm or clog main treatment clarifier pumps and skimmers. Pretreatment involves the receiving pit, drum screen or screening mechanisms. Netsol has a wide variety of equipment’s used in pretreatment processes.
Step 2: Primary treatment
Primary treatment is the physical separation of suspended particles such as fat, oil, grease, and other biological contaminants from a waste stream, resulting in a decrease in biological oxygen demand (BOD). Netsol is a one-of-a-kind array of primary treatment solutions that may be used in any business or environment. Our cutting-edge technology and extensive knowledge ensure that you get the finest solution for your project. EQ tanks, chemical reaction tanks and DAF come under this step. Netsol is the leading provider of the units involved in primary treatment.
Step 3: Sludge treatment
Sludge is generated from the above processes and needs further treatment. Sludge comprises water, dissolved organic and inorganic elements, and suspended particles, regardless of its source. About municipal wastewater sludge, suspended solids typically account for 25% of the sludge. The volatile solids (VS) concentration of the organic solids component of the sludge is usually regarded to be the most immediately helpful. These solids are known as biosolids, and they can be employed as soil fertilizers or have their latent energy converted to heat or a useful fuel (or biofuel).
Under this process comes sludge thickening and sludge dewatering mechanisms. These mechanisms are used to reduce the overall burden of the discharge.
