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 improving 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.
Better 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. Talk to our experts to find out how.
Our experts recommend: remove finer solids to improve 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.
Upgrading your screening equipment can help you to capture much finer particles from your water, 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 right screening system can produce treated water that can be used directly in secondary applications.
Our experts recommend: capture inorganics to protect expensive downstream 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 the level of treatment).
Removing inorganic particles before they enter expensive processes like Dissolved Air Flotation (DAF) boosts treatment efficiency and can sometimes remove the need for some of the equipment in the downstream treatment system entirely.
Implementing an ultrafine screening system will enable you to capture more solids from your flows than simply by using conventional screens, and modern ultrafine screens can be configured to discharge captured solids as a compacted, dewatered product 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.
