Meat & Poultry Processing Wastewater Treatment

Meat and poultry processing requires a tremendous amount of water both to create the end product and to maintain sanitary conditions, and all that water needs to be treated after it is used. Our solutions can help producers to improve operating efficiency, recover potentially valuable by-products, and reduce costly effluent discharge fees. 

Despite efforts to increase water use efficiency and water recycling, meat and poultry processors use a lot of water; beef producers, for example, require about 15 litres of water to produce one kilogram of beef. Dealing with all that generated wastewater represents a significant cost of operations.  With ever-increasing demands on production, meat processing plants are also very often constrained by available plant footprint or existing wastewater treatment options.

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

Our solution: ultrafine rotating belt filtration

The Hydro MicroScreen ultrafine rotating belt filter can eliminate the need for both the conventional screening system and the dewatering system, while significantly reducing the load sent to the DAF system, ensuring that it can operate at maximum efficiency. It will also help you to reduce effluent discharge fees

Capturing much finer particles than conventional screening, the system significantly reduces effluent TSS, particulate BOD and COD; in many cases, depending on the temperature, the system can also reduce 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 and slaughterhouses reduce their discharge costs and maximise the capacity and efficiency of expensive on-site wastewater treatment processes like Dissolved Air Flotation (DAF). The DAF process provides removals of very fine solids, oils and grease, but large solids can adversely affect the efficiency.  Removing as much solid material as possible upstream of the DAF plant helps you to optimise its operation and make cost savings.

The Hydro MicroScreen™ removes bulk solids from your flows with better performance than conventional screens, and it can be configured to discharge them as either 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.

Re-use water more effectively and efficiently

High-pressure, low-volume spray systems can reduce your overall raw water costs. Re-using water from operations such as chilling, scalding, and canning often requires treatment before it can be re-used.

For many types of meat processing applications, the Hydro MicroScreen™ provides the pre-treatment needed to help you recycle your plant water faster and more efficiently.

Maximise the efficiency of by-product recovery 

Nearly every by-product in meat processing applications has value, and discharging these materials to sewer systems can result in astronomical discharge fees.

The Hydro MicroScreen™ system can be sized to 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 wedgewire screening technologies and delivers a compacted, dewatered product that is cheaper to handle and transport.

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.
