The BIOTIM® anaerobic-aerobic biological wastewater treatment technologies are capable of handling the high-strength organic loads typical of dairy effluent. This reduces the environmental impact and helps dairies comply with stringent discharge regulations, while also preparing the water for potential reuse within the plant. The recovered biogas from the anaerobic wastewater treatment can be reused as a green energy source, also reducing the plants water, energy and CO2 footprint.

Dairy wastewater typically has a high BOD. KROFTA® DAF technology is frequently used for removal of suspended solids and Fat, Oil & Grease (FOG) in the rich wastewater. The fast and cost-effective DAF technology can be easily scaled to accommodate varying wastewater volumes, making them suitable for bath small and large dairy operations.

Our AQUALITY® reverse osmosis (RO) systems is designed to purify treated wastewater further. After primary and secondary treatments, RO systems can remove dissolved salts and micro-pollutants, producing high-quality permeate (filtered water) that is safe for reuse for various non-product contact purposes, such as cleaning, cooling, or irrigation, significantly reducing the freshwater demand. AQUALITY® Reverse Osmosis allows to recover up to 75 % of the treated wastewater.

Collected and stored rainwater from building roofs and other surfaces can be treated minimally and used for purposes like landscape irrigation or as make-up water for cooling towers, reducing dependence on municipal water supplies. But the recovered rainwater can be added to the biological treatment effluent and processed for further reuse in an AQUALITY® RO or HRRO process, leveraging a free and sustainable water source, enhancing water security.

During milk processing, significant amounts of water vapor are generated, which can be captured. Waterleau’s systems can recover this condensate, which is generally of high purity, requiring minimal treatment before reuse. Milk vapour condensate and whey permeate recovery not only conserves water but also recycles heat energy from the vapours, reducing energy consumption.

Waterleau can provide evaporation technologies to treat RO concentrate, reducing its volume and allowing for the recovery of salts and other minerals. This process minimizes waste disposal costs and can lead to medium or zero liquid discharge (MLD or ZLD) systems with minimal brine rejection.

Through these integrated approaches, Waterleau helps the dairy industry significantly improve its water management practices, turning traditional waste streams into valuable resources, and leading to substantial economic and environmental benefits. This comprehensive water recovery and reuse strategy is essential for sustainable dairy processing in today's environmentally conscious market.

Our expertise in improving the water and CO2 footprint management not only helps dairy companies in compliance and operational efficiency but also enhances their ability to report on sustainability, thus benefiting their public image and marketability. Through this holistic approach to environmental management Waterleau can be a valuable partner for companies looking to thrive under the evolving regulatory landscape and consumer expectations.
