With state-of-the-art filters, Hydrotech stands out as the global leader in microscreen filters for the municipal market. The unique filter design provides cost-efficient solutions with minimum footprint for municipal wastewater and potable water plants.
In 1995, Hydrotech introduced the first Discfilter to the Municipal wastewater sector for tertiary filtration. With the unique Hydrotech filter design and numerous key benefits, Hydrotech was able to revolutionize the market and became quickly one of the most common upgrades to municipal wastewater plants.
Don't hesitate to contact us. We have the solutions to your needs.
In the primary filtration application Hydrotech replaces the conventional primary settlers with a microscreen filter. There are major benefits with using Hydrotech filters in this application that suit the wastewater treatment plants. We can customize the perfect solution for each waste water plant and choose the correct filter cloth opening that will meet the clients special needs.
With our long experience within the municipal market Hydrotech can offer a customized solution that suits your needs for your plant.
With more treatment plants being subjected to higher intake flows and loadings due to increasing populations and randomly occurring rain event, Hydrotech is able to offer a solution for these situations. In the Northern part of Europe it is quite common that the rainwater from buildings, streets and parks get combined with the municipal wastewater network. During a heavy rain period, this will contribute to high hydraulic loads on the wastewater treatment plants that need to be treated. With Hydrotech filters we are able to offer a compact treatment step that would lower the load to the wastewater treatment plant and prevent expensive investments to be made due to sewage overflow.
Leading the market with advanced Phosphorus (P) removal for tertiary treatment Hydrotech has developed a unique solution to cost efficiently reduces the total P in waste water. There is a growing demand on the market today for reducing the outlet of nutrients in wastewater. Increased nutrients in the local recipients is a fact that all municipalities are facing worldwide and finding a proven technology that at the same time being cost efficient enough to do the job is challenging. Phosphorus is one of the main components needing to be reduced before discharging treated wastewater. With Hydrotech's latest development we are able with a minimum footprint to provide reduction of not only particular P but also dissolved P in the wastewater. Today we have over 15 global references installations and we are able to guarantee below 0,1mg TP/l.
As a well proven P-removal solution and strong local presence in different geographical markets, Hydrotech is able to provide an optimized solution for your special needs.
Effluent polishing is the first application of the Hydrotech Discfilters, with over 2 000 filters installed worldwide. The Hydrotech filters provide an excellent fixed barrier in the treatment process, providing the effluent polishing to help our clients meet the ever stricter demands on effluents from wastewater treatment plants. Hydrotech developed the Discfilter technology for the effluent polishing market and the launch took the market a large step forward from the conventional sand filters. Still today the Discfilters are considered as the most cost-effective technology for tertiary treatment, with Hydrotech still leading the technological development onwards.
Hydrotech's mechanical and process expertise helps thousands of clients achieve their requirements in the most cost effective way, while also providing long term support both directly and through our many local Veolia business units.
Through cooperation between two of Scandinavias main wastewater treatment developers, the treatment combination Hydrotech - MBBR (Moving Bed Biofilm Reactor) has been created, giving a new unique solution to clients all over the world.
The AnoxKaldnes MBBR technology is a compact, flexible and highly effective biological treatment creating flocs of the biomass in waste water with the use of biofilm. These flocs need to be removed in a following phase, where the Hydrotech Drum- or Discfilters are highly effective and proven technologies to achieve excellent filtration rates.
By combining the expertise of two leading companies in the development of wastewater treatment technologies you get an optimized solution designed to reach the end result from day one.
Optimal upgrade from Activated sludge plant for higher capacities.
The highly compact Actiflo® Disc, combining Actiflo and Hydrotech technologies, provides excellent removal of particles. The combination handles efficiently not only high SS loads, but also very fluctuating SS loads.
The Actiflo technology is a ballast sand settler that relies on microsand being mixed with flocculated waste water and polymers. This creates large and robust flocs of the particles in the water, making the technology a perfect combination with the Hydrotech filters.
