Meat & Poultry Processing Wastewater Treatment

We can help meat and poultry processors to improve operating efficiency, recover potentially valuable by-products from process water and wastewater, and reduce costly effluent discharge fees. 

Meat and poultry processors use a lot of water, and that water can contain a range of organic and inorganic materials - including grit, straw, sawdust, fecal matter and paunch waste. Treating and disposing of this wastewater represents a significant cost of operations.

With ever-increasing demands on production, however, meat processing plants are often constrained by space or by existing wastewater treatment options, and are limited in their ability to address water use as a way to improve profitability. 

Our food processing water management solutions can help you to reduce wastewater treatment costs, protect expensive downstream processes, increase your by-product recapture, and help you to reuse your water faster and more efficiently.

Rotating belt screening for meat and poultry processors

With potentially high levels of total suspended solids (TSS), biochemical oxygen demand (BOD) and chemical oxygen demand (COD) in process water, sewer discharge fees can represent a significant operational expense for meat and poultry processors. 

The Hydro MicroScreen™ ultrafine rotating belt screen can help you to reduce effluent discharge fees by eliminating the need for both the conventional screening system and the dewatering system, while significantly reducing the load sent to the Dissolved Air Flotation (DAF) system, ensuring that it can operate at maximum efficiency.  

Capturing much finer particles than conventional screening, the system significantly reduces effluent TSS, particulate BOD and COD, and in many cases, depending on the temperature, the system can also reduce fats, oils and grease (FOG). The Hydro MicroScreen™ produces a clean, dewatered output that can be easily transferred to other applications, re-used or more economically sent to disposal.

Protect expensive on-site wastewater treatment processes

Our solutions are tailored to help rendering plants, slaughterhouses and even small butcheries reduce their discharge costs and increase the capacity and efficiency of expensive on-site wastewater treatment processes like DAF. The DAF process removes very fine solids, oils and grease, but larger solids can adversely affect the efficiency; removing as much solid material as possible upstream of the DAF plant helps you to improve its effectiveness and cut the cost of treatment.

The Hydro MicroScreen™ removes bulk solids from your flows with better performance than conventional screens, and it can be configured to discharge captured materials as a compacted, dewatered solid ready for cost-effective disposal or onward sale. It can also be configured to separate solids from the bulk of plant flows into a slurry which provides additional downstream treatment options.

Protecting the capacity of your DAF allows your plant to maintain sustainably profitable operations and grow to meet increasing demand for your product.  The small footprint design of the Hydro MicroScreen™ system easily fits in your existing plant layout or within the footprint of the existing conventional screening system that it replaces.

Reuse water more effectively and efficiently

High-pressure, low-volume spray systems can reduce your overall raw water costs. Reusing water from operations such as chilling, scalding and canning often requires treatment before it can be re-used for activities such as clean in place (CIP).

The Hydro MicroScreen™ provides the pre-treatment needed to help you recycle and reuse your plant water faster and more efficiently.

Boost the efficiency of by-product recovery 

Whether blood, fat or bone, nearly every by-product in meat processing applications has value, and discharging these materials to sewer systems can result in both lost revenue opportunities and astronomical discharge fees.

The Hydro MicroScreen™ system can capture the fine particles (down to 100 micron) that are so frequently missed by conventional technologies like drum screens. This recovers significantly more by-product than conventional technologies, and delivers a compacted, dewatered product that is cheaper to handle and transport for sale to secondary markets.

Case Studies

Pennsylvania, beef

Faced with increasing effluent surcharge fees, a Pennsylvania deli meat producer wanted to upgrade its existing drum screens and DAF. Testing demonstrated that the Hydro MicroScreen™ could replace both the DAF and conventional screening system with comparable performance, in a fraction of the footprint and at a fraction of the price

Missouri, pork

A Missouri pork processor wanted to reduce its TSS, BOD and FOG effluent output to help avoid incurring sewerage surcharges. The Hydro MicroScreen™ system’s average removal rates of 79% of particulate BOD, 92% of TSS, and 90% of oils and greases represented a significant improvement on existing systems.

California, chicken

A chicken kill plant in California had a drum screen that was failing to protect downstream treatment systems, so they used a Hydro MicroScreen™ to increase solids capture. The system removed 3.8 tons of material per day that would otherwise have passed through into the equalisation basin, providing full ROI in just one year from solids capture alone.
