70 meters long chain scrapers to Trondheim


In October, the first installation of Hydria Water’s delivery of chain scrapers to the Ladehammeren RA waste water treatment plant in Trondheim.

Ladehammeren is the largest waste water treatment plant in Trondheim, located in the mountain, and is designed for 120,000 pe. Hydria Water has delivered four chain scrapers that are 70 meters long, and 7 meters wide, and the last installation is carried out this spring. The total order value is just over 2.6 million SEK.

-At the same time as our installation, renovation of the surface layers in all the tanks is ongoing. Because the waste water treatment plant is in full operation, only one tank at a time is available for renovation, therefore it will take about 12 weeks between each installation, explains Philip Carlsson, sales engineer at Hydria Water, and continues:

“We have not delivered to Trondheim municipality earlier and it is exciting that we got the confidence to do it this time. It will be a good reference facility for us in the Norwegian market in the future.

Orders from China and Dubai

Packing and preparations are currently ongoing for an order of 10 scrapers and four pipes that are to be shipped in cargo containers to the Harmony Creek Water Pollution Control Plant in Canada. The total order value is 3.5 million SEK and the client, NEXOM, is new to Hydria Water; the business deal has taken the form of a direct delivery to the contractor rather than to their reseller in Canada, as is normally the case. At the same time, two large distributors for trickling filters with a diameter of 32 metres are to be shipped to the Al-Aweer Sewage Treatment Plant in Dubai to join one that was sent last year. The total value of the order is 3 million SEK, and the client, Enexio, has been one of Hydria Water’s clients for several years.

Hydria Water modernises Kiev’s largest pump station

Kiev’s largest pumping station for wastewater, Obolon, which was recently modernised and to which Hydria Water supplied several products, was recently re-opened. The ceremony was attended by representatives of the Kiev mayor’s office, the Swedish embassy, and several journalists from newspapers and television networks.

The project to reconstruct Obolon pump station had a total cost of roughly 44 million UAH, and was carried out within the framework of an extensive modernisation programme of the Ukrainian capital. The new equipment will, among other things, facilitate considerable energy savings for the station.

– We have already cut energy consumption by 20 percent, and intend to further improve on this, Yuri Romanko, the assistant director of sewage pumping stations, told ABC News.

The project has been carried out by Hydria Water’s reseller AWP Nordic in Kiev.

A unique treatment plant is right now being built in Denmark, just outside Copenhagen in Hillerød Forsynings future energy, climate and environment park. Solrødgård treatment plant is based on innovative solutions and the latest technology, and will also be part of a recreation area and become a training center both for the public and for students. The treatment plant is expected to be operational by summer 2017, and Mellegård & Naij has delivered two Center Screens, two Wash Presses, two Shredders, two Gritwashers and an External Sludge Receiver in the autumn for a total value of 1.8 million Swedish kronor.

-It is an important reference for us. Danish architects often put a lot more effort into projects, even when they are designing treatment plants. It’s starting to change in Sweden, even though we have not progressed as far, says Stefan Naij on Mellegård & Naij.

The first order went from Skövde in mid-November, and the last at the end of the month.

-We have been working on the order for about a year, it is a very interesting project for us which will hopefully also become a display object even for us, says Mattias Ahlstrand, production coordinator of Mellegård & Naij who was responsible for the project, and continues:

-It’s a demanding customer – and we are happy for it. It makes us keep an even higher level, and it raises the standard of the entire operation.
