The Sludge Detector, your new friend for a clean water

Nowadays the treatment of the wastewater became an international priority: people realized that the water is a rare commodity that we have to stop wasting at any cost. However, the 98 percent of the used waters in the world are not recycled, while millions of people still do not have any access to drinkable water in the poorest countries. Fortunately, there are many water treatment plants which take care of the wastewater treatment to enable them to be reused.

Ecologic impact in UK

As a pioneer of the industrial revolution, the United Kingdom has not always been respectful about the environment: the excessive human activity, especially in the different factories, made of the country one of the most polluted in the world. But since a few year, the successive governments became aware of the negative impact of the outrageous consumption on the ecology, and work more and more towards the preservation of the natural resources.

Sludge in water: how to get rid of it?

The used water contain some waste, impurities and sludge that we have to remove to make the water suitable for consumption again. It calls for a specific and strict treatment: firstly the water is filtered through a big sieve to remove the biggest impurities, then it is degritted and degreased. After it is treated once with chlorine to remove the pathogenic bacteria, and sent through a big sedimentation tank. Once the suspended particles fell at the bottom of the tank, the water is aerated to bring oxygen to it, then it is treated twice with chlorine and ozone to purify it. Finally the sewage sludge is collected to be treated as well.

What is the sludge detector?

The sludge detector is a little case equiped with several measuring tubes, which analyze the composition of the water every hour: it enables the sludge traces to be spotted in the used water, and so remove them efficiently.
