Unrevealed opportunities within industrial water treatment
For industrial players, making better use of industrial water is an important driver of profitability and sustainability. With today’s technology, industrial process water can be purified even into drinking water, and at the same time, chemicals, for instance, can be recovered and reused. Similarly, heat can be recovered from wastewater, and closed water cycles can be implemented to cut the water consumption. With Adven’s holistic approach our customers get an understanding of significant opportunities in savings and lower emissions. Let’s reveal your opportunities!
Industrial water treatment:
Closed water cycles
Closed water cycles may very well be the mainstream of improved competitiveness of an industrial production plant. It is important for companies to identify and manage their water risks and to cleverly reuse industrial water. In practice, closing the water cycle means that the same water circulates in for instance in the cooling system, with no need to take new water from initial water source or water body. The cooling water is cooled in stages and the heat may also be recovered. By increasing the efficiency of water use companies can easily reach reductions of over 30 % in total water consumption which also helps to meet the environmental requirements.
On-site wastewater processing and biogas
An increasing number of companies are considering new ways of processing their wastewaters. Onsite wastewater treatment systems are used to treat wastewater from industrial processes and return treated wastewater back into the receiving origin. There are many technologies for wastewater treatment and Adven always utilizes methods that best fit to the customer’s situation. As an example, reject-water is a typical challenge at the biogas plants. Through MVR-evaporation even up to 90 % of the side stream of a biogas plant can be dewatered which results in significantly cheaper storage and transportation expenses while enabling recovery of clean water. Read about the MVR evaporation.
Efficient sludge treatment and reduced sludge generation
Large amounts of sludge are generated annually in the treatment of industrial and municipal wastewater. Sludge contains water and many different valuable substances such as nitrogen and phosphorus but also hazardous waste such as heavy metals and chemicals. Technical solutions to turn sludge from a useless by-product into a valuable resource already exist. One of them is converting nutrient-rich side streams into biogas and to use the biogas in vehicles.
How does onsite biogas production work in an industrial setup?
Organic side streams from for instance enzyme production or wastewater treatment plant, are delivered to the biogas production facility typically via a closed pipeline. After the production of biogas, the digestates can be used to produce solid soil-improvement materials and liquid nitrogen fertilizer for agriculture. High volumes of water typically contained in sludge can also be directed to the biogas plant, and most of it cleaned using the same technology as is used for producing potable water. The purified water can be reused in industrial processes, and the closed solution reduces clean water consumption.
Water treatment technologies
Adven does not represent any specific technologies instead, we realize complete solutions optimized to the customer’s process, making extensive use of a range of proven technologies. Biological water treatment methods provide solutions for instance for the removal of organic wastewater contents. Biological water treatment methods can be used with different mechanical or gravitational separation methods to achieve customer needs. In the area of water purification, water cycle can be closed using a semi-permeable membrane and evaporation methods, which allows the same water to be cost-effectively reused again and again. In practice, cost savings arise thanks to the reduced need for water and chemicals and the lower volume of sludge that is produced. In concept development phase the pilot studies can be conducted to be able to identify the optimal solution.

Water consumption at Nammo propellant plant cut in half with Adven’s energy solution
Evaporation is critical for us to be able to utilise the nutrients contained in our reject waters. Adven’s evaporation solution removes some 90 % of the water, which makes the fertiliser cost-effective to transport and easier for farmers to handle.Terje HyldmoManager, Commercial and Business Development, Biokraft.
