Secondary & Further Food Processing Wastewater Treatment

Our industrial water screening and treatment solutions can help secondary and further food processing businesses to improve profitability through increased efficiency, improved water recycling, better recovery and reuse of process material, and reduced effluent surcharge costs. 

Secondary (or further) processing is a broad group of activities that food processors use to add value to food products. Secondary food products include ready-made meals, breakfast cereals, cured meats, chicken nuggets, pet foods and the like. 

Secondary processing lines have one thing in common: water use. Most further processing activities require water: production lines need continuous cleaning, products need washing and conveying, cutting and processing equipment needs to be cleaned...the list goes on. And of course, sanitation is paramount for operational success. 

Steps like optimizing pressure and volume efficiencies on spray systems, intermittent flows, cascading rinse processes, and condensate recovery all help to reduce water consumption, but with all the water that is needed for these processes, wastewater is inevitable - so treatment efficiency and effectiveness is critical to profitability. 

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.

Rotating belt screening for secondary and further food 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 secondary and further food 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 finer particles than traditional screening technologies, the system greatly reduces effluent TSS, particulate BOD and COD, and under certain conditions can also reduce fats, oils and grease (FOG). The Hydro MicroScreen™ generates clean, dewatered output that can be easily transferred to other applications, reused or sent to disposal.

Remove solids for water recycling and reuse

Depending on the source, some of your plant water can be reused in applications where lower quality water can be tolerated. If solids have been removed then flows from processes such as cooling and canning can often be reused immediately upstream on processes that don’t require high purity. However, any solids present in these flow streams limit reusability options as they will clog pipes and spray nozzles and impact distribution systems.

The Hydro MicroScreen™ captures much finer particles than conventional screening systems, removing Total Suspended Solids (TSS), particulate Biological Oxygen Demand (BOD) and Chemical Oxygen Demand (COD) in wastewater streams. In many cases, depending on the temperature, the system can also reduce FOG. The Hydro MicroScreen™ produces treated water that can be used in secondary applications

Protect expensive wastewater treatment processes

Process water from secondary processing plants often requires expensive advanced downstream treatment to reduce BOD and TSS before the water can be sent to a sewer or river, or land applied (depending on level of treatment). Removing fine particles before they enter expensive processes like Dissolved Air Flotation (DAF) maximizes treatment efficiency and can sometimes remove the need for some of the equipment in the downstream treatment system entirely.

The Hydro MicroScreen™ removes 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

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.

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

Michigan, cereal

A large cereal manufacturer was looking to expand their ageing on-site wastewater treatment system to meet growing demand for their product, and address escalating effluent surcharge costs. Pilot testing demonstrated that the Hydro MicroScreen™ system would save them over $2M in construction costs, reducing their surcharges by 30% and eliminating the cost of disposing of wet solids from their primary screen.

California, chimichangas

A southern California chimichanga manufacturing facility was facing ever-growing sewer surcharge fees. A Hydro MicroScreen™ demonstration project indicated that the system would pay for itself within seven months in surcharge reduction alone.
