The food and drink sector and other industries are expected to reduce water use and take a more responsible attitude to environment protection. On-site anaerobic systems can support re-use of cleansed effluent or their discharge safely into local watercourses. Do you want to transform your site’s water efficiency, while:
• Adding value to unwanted production residues?
• Reducing cost of conventional aerobic treatment?
• Cutting your net water use and water footprint?
• Allowing sites to discharge to a local watercourse?
• Making sites more sustainable and enhancing your brand?
If so, investigate how cost-efficient grey water recycling using on-site Anaerobic Digestion (AD) can improve your site’s environmental credentials.
Tackling Industry Challenges
Food and drink manufacturers are subject to ever tougher environmental legislation and demands for sustainability reporting from customers and investors. If faced by escalating residue disposal costs and stringent water treatment charges, integrated on-site digestion and effluent treatment offers an attractive solution. Many food processing companies are reliant on outdated aerobic technology to treat their effluent – incurring excessive treatment costs
How Clearfleau Can Help
Clearfleau’s on-site anaerobic system extracts energy from a range of production residues. This approach also allows cleansed waters from the digestion process to be discharged to watercourse or re-used on site to reduce consumption of increasingly scarce water resources. Combining AD with aerobic post-digestion treatments to remove nutrients , means you can recycle process water and reduce the impact of your production activities on the local environment.
For instance, Clearfleau’s on-site bio-energy plants built for Diageo are enabling water recycled from cleansed distillery production residues to be discharged to the river Spey (famous for its salmon-fishing). On sites with restricted access to fresh water, cleansed water could be further treated for re-use as grey water. Our integrated anaerobic digestion systems offer a practical and cost effective way to better manage bio-degradable production residues and improve your water use profile.
Benefits to Your Business
Clearfleau has built two digestion plants for Diageo‘s malt distilleries in Scotland. They handle over 1000m3 of distillery co-products on a daily basis, providing energy for the sites but also using cost effective aerobic treatment to allow cleansed effluent to be discharged. This approach has provided the Scottish distillers with a new model for handling its residues.
For Nestlé, Clearfleau’ s smaller on-site AD solution cleanses 200,000 litres of effluent daily. This plant is discharging process water to the sewer with a 95% reduction in COD load. With minimal further treatment food processors could allow grey water re-use on-site.
On-site water solutions (commercially viable due to value of energy output) are key to sustainable manufacturing, allowing re-use or recycling cleansed water.
