Meat Processing and Water Filtration

Dissolved-Air Flotation Systems Optimize your Meat Processing Systems and Prevent Wastewater Pollutants!

Meat wastewater processing is among the most particular and demanding of water separation tasks, producing some of the highest biodegradable effluents of any industry. Between blood, bone, and tissue, wastewater filtration and sterilization of meat processing contaminants is difficult due to meat processing solids having varied densities and materials; likewise, the water and chemicals used to treat and sterilize wastewater filtration equipment could become pollutants in their own right.

Are there meat wastewater filtering solutions that can minimize the need for additional chemical agents, but also allow for recovery of valuable water to be re-used in meat processing facilities? Yes! At Archer Separation, we partner with industry-leading manufacturers in separation and filtration equipment that can dramatically improve results in slaughterhouse and meat processing wastewater with removal efficiency up to 99%.

With these demands and technologies in mind, one may ask: what equipment can prevent contamination and recapture meat processing water so effectively, and how exactly does it work? The solution is Dissolved Air Flotation, or “DAF” systems, which use a combination of processes to first coagulate solids and liquids, then separate them by gentle agitation. Our partner SIGMA DAF Clarifiers provides the following diagram of the DAF system process:

Separating the considerable volume of organic solids from the meat processing wastewater is as follows: pre-screening, coagulation, flocculation, then finally the titular dissolved-air flotation. At Archer Separation, we provide equipment, remote monitoring and other services to best optimize each stage of the process for maximum filtration.

Pre-screening

Using a series of increasingly-fine grates and screens, slaughterhouse and other meat processing wastewaters are filtered down to a consistent, homogenous size. Because the needs for different animal byproducts vary, SIGMA DAF Clarifiers advises sieves, screens, and servicing bypasses on a use-by-use basis; Archer Separation has a proven record for this degree of customization and meeting user needs.

Coagulation

Using versatile, low-toxicity chemical agents such as aluminum polychloride (“PAC”) targeted for your meat processing filtration system's unique pH, the solids in the meat processing wastewater are bound into polymer chains through rapid agitation—with ideal polymers, pH balance and agitation, this process takes only five minutes. Archer Separation provides these settings for you in-person and remotely.

Flocculation

Flocculation is the settling of materials in solution; in this case, the polymerized meat solids are now agitated gently and deliberately with specialized propellers that don't break the emulsion. Though this process sounds as delicate as soufflé, the DAF machinery and resulting dissolved-air polymers are highly durable and this ‘slower’ part of the meat wastewater process only takes about ten minutes.

Dissolved-air flotation

After fifteen total minutes of coagulation and settling, the micro-bubbles are introduced to the dissolved-air filtration system's basin. These DAF system micro-bubbles adhere to the coagulated floccules and attract them to the top of the basin, where a scraper blade continuously removes the suspended meat processing solids for disposal. This leaves highly purified water content, without the additional need for thickeners to solidify the resulting meat processing sludge.

Following DAF filtration for meat processing, the resulting solids can be disposed responsibly and the wastewater recycled into washwater for your system. Compared to non-DAF alternatives, the resulting sludge has more solids and (following additional concentration, digestion or sterilization processes) is typically ready for discharge. There are many details specific to your meat processing facility that a dissolved-air flotation system can assist with, be it as your primary wastewater filtration solution or a secondary cost-effective supplement to clarify a flotation-based bio-reactor. Application of a dissolved-air flotation system in your meat processing facility provides a more clarified output that's easier to sterilize and provides reclaimed water, saving you on water costs and pollutant fees. At Archer Separation, we're committed to helping you integrate solutions that will help you meet your meat processing needs in hygiene, efficiency, and cost-effectiveness.

We understand your meat processing, meat wastewater filtration, and other dissolved-air flotation requirements, and will meet those needs with the best technology available!
