The Industrial Sector:

Industry sector design and develop underwater cleaning equipment for tanks and reservoirs in industries, Our systems have been delivered and installed cleaners in nuclear power plants, glass factories, fish farms, gypsum plants, pulp and paper mills and several other applications where there is a need for cleaning (sludge removal) without having to drain the water.

Weda has a unique experience and know-how from more than 50 years activities in the development and production of products for under water use. WEDA´s Industrial division is aiming to find solutions for all applications of cleaning under water may it be with existing products, products that need to be customized or new products designed in cooperation with the client.


New efficient cleaner for smaller reservoirs

Traditional cleaning of all types of reservoirs has required draining with staff inside the reservoirs. This is no longer accepted on many of the world markets due to the safety risks for the staff. Plus the unnecessary waste of water

The alternative with divers is becoming less popular due to higher costs as well as the safety issue. Few consumers enjoy the thought of divers in their drinking water.

Weda underwater cleaners makes it possible to clean reservoirs of all kinds and totally avoid human entry. Besides this a lot of water is saved. In many cases processed water.


For cleaning water reservoirs and water towers

For the cleaning processes in the industrial sector, the reservoir has not to be taken offline, because that can lead to major disruptions in the main supply system. Emptying a reservoir is time consuming and cleaning is labor intensive. Sending divers down in drinking water also entails a risk for contaminating the water. When we developed the VR-600 our ambition was to design a vehicle that could clean effectively without having to shut down the reservoir and without sending personnel down into the reservoir.

The VR-600 is remote controlled and equipped with rotating brushes and a powerful pump that directly pumps out all loosened sediment – without raising turbidity in the reservoir. The VR-600 is equipped with a video camera that facilitates inspection of the inside of the reservoir. The entire cleaning process is documented and the customer receives both a videotape and a written report.



For sediment removal in reservoirs

YT-600 is a remote controlled vehicle for sediment (sludge) removal in all sorts of reservoirs. The powerful on-board submersible pump and wide nozzle allows for efficient cleaning of large bottom surfaces.The sediment is pumped through a hose to a selected discharge point or to a filter.
By using the YT-600 the reservoir may stay in operation during cleaning. The YT600 is used today in several different industrial applications, from mines and desalination works to cooling towers in the processing – and other industries.


For cleaning sand filters and large basins


The YT-800 is an electricity-operated remote controlled submersible robot for cleaning large underwater surfaces, such as the bottom of a sand filter. The powerful pump and wide nozzle make it possible to clean large areas in a relatively short time. The sediment is pumped through a hose to a designated point of discharge, such as a sand treatment station. Traditional cleaning using loading machines, conveyor belts and such require costly investments and manual filter cleaning is very labor intensive. Both methods require that the filter is drained and taken offline. With the YT-800, cleaning can be carried out during full operation.

Easily operated by one person, the YT-800 is remote controlled using a radio hand box. The vehicle can be equipped with underwater cameras to facilitate long-distance operation from a van or operations room for example. Using the

Other applications for the YT-800 include cleaning infiltration dams and surface cleaning large outdoor basins.
