EIO - Product eco-innovation – Solution to product energy from biomass cleaner and more energy efficiently
Kemira Plc operates in chemicals industry and is focused on serving customers in water-intensive industries. Their aim is to improve the energy, water and raw material efficiency of their customers via water quality and quantity management. The company developed DesinFix, a complete, chlorine-free disinfection system that disinfects water in ten minutes, and within an hour no active substance can be detected as the compound (DEX-135) breaks down into carbon dioxide and water. DesinFix is based on the combination of formic acid (hydrogen carboxylic acid) and hydrogen peroxide. It is primarily targeted to municipal waste water treatment plants, but the method can be applied also for example to industrial process waters. (Kemira DesinFix 2011.)
Kemira has long roots in the Finnish know-how as it was established already in 1920. The company has a large-scale research and development operations, which expenditure totalled €47m in 2009. The R&D concerns, in addition to drinking and waste water treatment, pulp and paper, oil and mining, and other water intensive customer industries. (Kemira 2011.)
- Not known yet
- EU bathing water directive
- Increasing demand for water disinfection in water reuse applications
- Low energy consumption & competitive operational costs
- Minimal maintenance requirements, compact size & easy installation
- Lower investment costs (compared with UV-light or ozone disinfection)
- Versatile use of technology
DesinFix was invented particularly to meet the increasing demand for waste water disinfection in water reuse applications (such as agricultural and landscape irrigation, industrial applications; disinfection of internal service water), the environmental effects of the innovation concern the sustainable (re)use of water as well as sustainable energy and material consumption. DesinFex has low energy consumption and inexpensive operational costs, which also contributes to the total cost, which is well below the alternative methods. Thus, in the long run the sustainability effects could also concern cost reduction and market creation through new improved and sustainable water management solutions at both national and the EU/ global level.
The DEX-135 compound used in this innovation does not leave any toxic disinfection by-products in water and enables a 99.9999% kill ratio. Thus, the innovation excludes health risks (infections, gastroenteritis cancer etc.) as well as contamination damages of nature. The system can also handle rapidly varying flow rates guaranteeing continuous disinfection even in more demanding environments.
