The dairy and food and beverage industry is growing and shifting rapidly, yet many facilities still rely on wastewater systems designed and built years ago. As production needs change, hidden inefficiencies and operational blind spots can develop over time.
Reevaluating your wastewater system can uncover operational, financial and sustainability opportunities. However, because wastewater composition and production requirements vary from plant to plant, there is no one-size-fits-all solution. Understanding whether your current system is still meeting your facility’s needs requires a closer look at how you operate today and where your business is headed.
A thorough wastewater assessment starts with three key questions:
Question 1: Is your system still adequate for the product mix you’re producing today?
The products running on your line today may look vastly different than what your wastewater system was originally designed to handle 10 or 20 years ago. Production shifts, such as adding a whey line or pivoting to high-protein yogurt, can change the makeup of your wastewater and place new demands on existing treatment systems.
One sign that your system is no longer keeping pace is having to limit wastewater discharge to maintain compliance with local regulations. In more serious cases, an inadequate or overtaxed system can result in a notice of violation from your local Publicly Owned Treatment Works (POTW) for non-compliance.
To stay ahead of potential issues, sample your wastewater composition regularly, ideally annually or bi-annually, and compare the results against current regulations and pending changes. This proactive approach can help identify opportunities to right-size treatment processes or reduce the volume and BOD levels discharged to the local POTW, potentially lowering facility costs while supporting continued compliance.
Question 2: Are you familiar with the available technology for wastewater treatment and its capabilities?
Wastewater treatment technology continues to evolve, but many facilities still rely on legacy systems installed decades ago. Advances in treatment methods, equipment manufacturing and automation have created new options for removing BOD, COD and TSS more efficiently, often with smaller footprints, less chemical use and lower operating costs.
Modern systems can also offer greater process control and automation, allowing operators to respond more quickly to changing wastewater conditions while improving safety and reducing manual intervention. Understanding these capabilities is an important first step, but identifying the right solution requires evaluating available options against your facility’s wastewater characteristics, operational needs and long-term goals.
Question 3: Are you maximizing your opportunities for wastewater reuse and resource recovery?
Treating wastewater purely as a disposal liability can mean overlooking opportunities to reduce water consumption and operating costs. Given the large volume of wastewater generated by dairy and cheese production, treated wastewater can potentially be reused on site for applications such as equipment and general sanitation or boiler make-up water.
Treatment processes such as dissolved air flotation (DAF), followed by filtration and pH adjustment, can treat wastewater for certain non-potable uses. Identifying where treated wastewater can be safely reused can help reduce incoming water demand, chemical use and discharge volumes to the local POTW.
Reducing water consumption and discharge volumes can lower operating costs while improving your facility’s sustainability impact. Evaluating reuse opportunities as part of your broader wastewater strategy can help you identify practical ways to improve both operational and environmental performance.
Look Beyond the Equipment
Addressing wastewater challenges is more than an equipment purchase. It is a complex facility integration decision that must account for your current operations, future production needs and the limitations of your existing building.
Taking an equipment-first approach can lead to costly delays if a new treatment system is selected before evaluating your facility’s footprint, utilities and structural constraints. At Ryan, we combine our facility design and construction expertise with established relationships with specialized wastewater consultants to evaluate whether new technology can be integrated into your existing facility or if an expansion is the smarter long-term investment.
This holistic approach provides a more complete understanding of project scope and preconstruction costs, helping you evaluate the business case before moving forward with a major investment.
