SOLUTION FOCUS Potato Waste Becomes Clean Water, Energy Engineered wastewater-effluent-treatment systems are generating 45,000 liters of potable water per hour and 3.2 MW of green energy. FOOD AND BEVERAGE PROCESSING involves a significant amount of wastewater, most commonly treated in a typical anaerobic-aerobic wastewater-treatment plant. The effluent produced from this conventional type of treatment is an ideal source for further refining into perfectly hygienic, potable drinking water, and clean energy-something that can help plants save on water intake and energy costs. While biological effluent use is a popular way to improve plant efficiency, it's not as easy as it seems. In the food and beverage industry, three conditions must be met: ■ All production must allow the reuse of biological effluent. ■ The available effluent must be of an acceptable quality, allowing successful tertiary treatment. ■ The generated concentrate should still be disposable. Waterleau (Leuven, Belgium, and Victor, NY) is a global provider of environmental technology and a pioneer in water and wastewater treatment that offers a variety of solutions for processing wastewater in the food and beverage sector. The company works with individual plants to design and build solutions based on their respective projects and treatment conditions. An example of this is Farm Frites, headquartered in Molendjik, The Netherlands. Reducing water footprint With a global capacity of 1.3-million tons of processed potatoes annually and 1,500 employees, Farm Frites (farmfrites. SEPTEMBER 2016 com) is one of the largest operations of its kind in the world. Over the years, though, this successful company has faced groundwater scarcity, limited groundwater-permit availability, increased costs of sourcing tap water, and stringent wastewater-discharge regulations. To deal with these challenges, Farm Frites partnered with its drinking-water supplier, De Watergroep (Brussels). Together, the organizations developed a sustainable, tailor-made solution that met the potato-processor's water demand and complied with the governing water agency's strict regulatory framework. De Watergroep, in turn, partnered with Waterleau for the design and construction of the wastewater-effluenttreatment solution. Waterleau's Boomerang water-reuse technology consists of a successive ultrafiltration (UF) and reverse osmosis (RO) treatment process that converts wastewater into potable water that can then be reused in the plant. Ultrafiltration membranes provide a physical barrier to remove bacteria, suspended solids, and harmful pathogens. This technology has been proven in many water reuse installations worldwide. The resulting water quality is characterized by a low turbidity and SDI (silt density index) value. It is fed directly to the downstream RO installation, extending RO lifetime and reducing its associated operating costs. During MAINTENANCETECHNOLOGY.COM | 45 http://www.MAINTENANCETECHNOLOGY.COM
