Dewatech

The history of Dewatech starts back in the 1950s. Back then, the company worked with regular sewer drainage. Throughout the years it stood clear to us that the market was in deficit of a plant that could treat the contaminated waters as well, and that was the beginning of Dewatech in its current constellation. We constantly work to ensure that our plant and our processes are the best possible in order to guarantee working methods that are as environmentally friendly as possible.

Out permit allows ut to handle up to 50 000 ton of waste each year. The waste contains of water with different kinds of contamination such as oils and sludge. We treat and purify the waste to separate the water from the contaminations and end up with a water clean enough to be released back into the ocean. To get the results we want, we need to work with moderna och effective techniques.

What we do at Dewatech, is to handle and treat a large amount of contaminated oils and emulsions from places like harbors, garages, gas stations and so on. When the oils arrive at our plant, they are contaminated with things like gravel, dirt and construction waste.

We separate the oils from the contaminations with different methods such as gravimetric separation, heating, mechanical filtration and ultra filtration. When the oils are recycled, we send them to our partners, These partners have permits to convert the oil to oils for burning and the more refined oils turn back into engine oil.

The water that is cleaned out in these processes is sent back into our purifying plant in order to maintain the treatment towards getting an ultra clean water.
