What are the Benefits of Electrocoagulation in Meat manufacturing?
The meat industry includes slaughterhouses and cutting plants, as well as meat product manufacturing plants (fresh, cured, or cooked). Thus, the meat industry produces transformed meat products, whereas the former produce carcasses, half carcasses, and meat cuts for consumption (seasoned and cured meats, hams, sausages, etc.).
The production of wastewater in the meat industries differs significantly, depending on the type of installation. As a result, wastewater from meat manufacturing sector should be treated using the electrocoagulation process, as it provides many benefits.
Electrocoagulation Process for Meat Manufacturing Industry
Electrocoagulation (EC) has been widely used in wastewater treatment for several decades. However, it has only recently gained recognition as a viable and effective treatment method, as a result of advancements.
It achieves comparable, if not better, treatment results than conventional chemical treatment in many industries. In an integrated treatment system, it is becoming known for its lower lifecycle costs.
Benefits of EC Process
It has a few key advantages when it comes to treating wastewater from poultry and meat processing.
With high solid levels in the wastewater, treatment will inevitably produce some sludge. Because chemical coagulation treatment is an additive process, sludge volume is typically high in chemical treatment processes. This sludge is typically hazardous and must be treated separately and disposed of carefully, incurring additional costs for these facilities.
Because, no such chemicals are typically required in an EC system, less sludge is produced, and it is typically non-hazardous. The EC sludge can be taken care of more easily and cost-effectively after dewatering. It can be sold to a local farm for use as fertilizer.
2. Reusing water
Industries are under increasing pressure to implement more sustainable practices, particularly those involving water use. As freshwater resources dwindle, reducing water consumption becomes critical. Reusing raw water is one method of reducing raw water demand. Treatment systems that can treat wastewater to a reusable level can be large and expensive in some cases, but with EC, systems can be modular, compact, and less expensive.
3. Reduction in the contaminant levels
The EC process can significantly reduce several of the contaminants, leaving post clarification and polishing filtration and disinfection, to finish the treatment.This treated water could be used for post-process cleaning, which could consume a significant portion of the total volume of water used during processing.
With the amount of raw water that these facilities use in a year, they could typically save a significant amount of money, by reusing wastewater instead.
4.Pathogen and fecal coliform reduction
Fecal coliform is not always harmful in and of itself, but it is typically used as an indicator of the presence of fecal matter and pathogenic substances. Fecal matter, as well as pathogens such as bacteria, cysts, and viruses, are almost always present in the meat and poultry industries. Fortunately, EC is quite capable of significantly reducing, if not completely eliminating, these pathogenic substances.
The electric fields produced by the electrodes can weaken and permeate cell membranes, and the overall charge neutralization allows microorganisms to flocculate, or adhere to larger particles and settle.
5. Recycle Fat/Oil/Grease (FOG)
In the meat and poultry industries, fats, oils, and grease are common wastes. Because of its in-situ emulsion destabilization and flotation capabilities, EC effectively removes emulsified fat, oils, and greases.
Instead of being discarded, these products can be recycled and processed for fuels, either on-site or sold to another company for this purpose. FOG can also be used to generate heat energy, either directly or by converting it to electrical energy.
Generally speaking, electrocoagulation is an excellent treatment method for the meat and poultry industries.
Netsol Water specialized EC systems, when used as part of an integrated treatment system, provide a lower life cycle cost with reduced sludge disposal costs, and the ability to minimize production costs by allowing water reuse or safe discharge.
