Industrial water treatment

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.

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.

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.
