Dallas, TX — Whether manufacturing chocolate and lollipops or popcorn and potato chips, candy and snack manufacturers share at least one thing in common — wastewater often contains high and variable amounts of dissolved sugars, measured as biological oxygen demand (BOD) or chemical oxygen demand (COD), low pH and high suspended solids. The wastewater also often contains free and emulsified fats, oils and grease (FOG).
Different types of biological technologies are preferred for this wastewater because of high organic loading but disadvantages like longer aeration times, a large footprint, high energy demand, sludge management costs and obnoxious odors are associated with the current conventional technologies. These conventional challenges coupled with increasing local surcharges and a growing demand for eco-friendly practices has added to the frustration of how best to manage wastewater.
Luckily, just as we are seeing great innovation in every other aspect of technology, wastewater treatment too has evolved. It’s now possible to treat wastewater efficiently and effectively within a sleek, self-contained system. Baswood, Inc., a Texas-based water technology company, is on a mission to revolutionize the way we think about and use water, and has made this vision a reality with the introduction of the BioViper system.
A first of its kind, the BioViper features a patented aerobic/anaerobic integrated media system (AIMS) that combines anaerobic and aerobic solutions both in one platform. The system consists of a sequence of enclosed vertical tanks, customized as per the application. In each tank, air rises from the bottom (submerged zone) to the top (trickling zone). Wastewater flows from top to bottom through a series of biofilms — organic biomass that grows in varying quantities. These different zones, customizable to the nature and strength of the wastewater, work together synergistically to break down and remove organic compounds. AIMS technology is used along with another patented innovation, Dry Cycle Aerobic/Anaerobic Digestion (DCAD) technology, to maximize treatment efficiency and minimize residual biosolids production.
The diversity of biomass enables the system to handle fluctuating loads of wastewater without shutting down, unlike conventional, suspended growth systems that need a consistent load to maintain the healthy and efficient biomass. This is a necessary advantage for candy and snack manufacturers, that might produce more concentrated wastewater one week and less the next.
The Baswood BioViper has completely changed the game when it comes to wastewater management. The innovative new system makes it easier to conserve and naturally treat wastewater, while actually saving time and money. BioViperTM is specifically designed to treat high-strength wastewater streams with lower energy consumption, and the entire process takes place within a sleek, self-contained system that requires up to 75 percent less space than traditional wastewater management solutions.
Even within a vastly reduced space, the BioViper system removes 90 percent or more biological oxygen demand (BOD), thus cleaning water before it’s either sent back to the municipality or reused in a manufacturer’s plant with additional treatment. This not only reduces wastewater management costs; it actually improves processors’ operational efficiency and environmental credibility. This can be a huge value for candy and snack manufacturers that require an effective and efficient wastewater management program to treat high levels of BOD and TSS.
As a fixed-film, biological system that uses different treatment environments, the Baswood BioViper is uniquely self-contained. Whether placed inside or outside, the vertical tanks that treat the wastewater take up only one-tenth the space that a traditional wastewater-treatment system using aerobic ponds would occupy. Plus, the enclosed tanks mean odor is better managed.
Many candy and snack manufacturers often have the challenge of finding modern, energy efficient solutions to retrofit in their old factories. Fortunately, the BioViper system is modular and scalable. It can be easily expanded with additional reactors as plants grow and wastewater needs increase.
From an operations standpoint, the units are internally self-buffering and extensively automated, meaning they require minimal human intervention, so manufacturers can focus on production and not have to worry about wastewater. However, the SCADA system provides the operator with complete control should they need it, such as during maintenance.
As more and more municipal waste treatment facilities impose enormous surcharges on companies that exceed strict BOD limits, it has become financially imperative for food and beverage firms to clean up their effluent. But there are other reasons to do so. Growing stakeholder and public scrutiny on corporations’ environmental and sustainability practices has put pressure on manufacturers to improve their water management and conservation. BioViper empowers processors to have a positive impact on their communities while also minimizing their carbon footprint.
While BioViper can make it easier and more efficient to manage wastewater, it’s also a sustainable solution to conserve water. Afterall, wastewater cleanup is not only better for the community and environment, but also the first step toward water reuse and ultimately making water scarcity a thing of the past.
