Kendensha History and Development of KDS Separator 2

What is a user-friendly waste water treatment system?

The first stage of wastewater treatment is to separate solids from liquid or to filter them. In the case of household waste, this is a drainage strainer.
In industry, solid-liquid separators play this role.

There are various types of solid-liquid separators or sludge dewatering devices, such as screw presses, roller presses, etc. However, when we listened to clients who use them, the common problem was clogging of filters. At home, when a certain amount of solids accumulate, the strainer needs to be washed once. Similarly, when the filter of a solid-liquid separator becomes clogged, it has to be stopped and washed back with water. In both manufacturing and livestock industries, wastewater/sludge accumulates during the cleaning, and the labour and time, that should be spent on production is lost in the maintenance of wastewater treatment devices. Besides, it requires water, which is an extra cost.

To prevent screen clogging, therefore, reduces the time and effort spent on cleaning, reduces the use of cleaning water and enables continuous treatment. The result is a dramatic improvement in usability.

From subcontractor to manufacturer

We were convinced that if we could develop such a device, Kendensha would be able to grow from being a company that made products commissioned by clients to a manufacturer that offers its own products.
Although it had been interesting to manufacture various types of labour-saving automatic devices or algae cutting ships, it was difficult for us to decide on the budget and delivery date　ourselves, which inevitably led to compromises on the quality and price of the products. If we became a manufacturer, we would not have to compete on price and be able to produce products of satisfactory quality. To add to that, the company management would be more stable.

So, what structure prevents a filter from clogging?
