| |
|
|
Published August, 2010 Spaans Archimedes screws generate electricity from River Great Ouse to power Borough Hall Spaans Babcock have been contracted to produce and install two screw generators for the Bedford Borough Council near Bedford, UK later this year. The preparatory work will start at the Boat Slide Weir Bridge later this summer. The screws will generate energy from the River Great Ouse. The scheme includes a state-of-the-art Archimedes Screw Turbine, which could generate up to 180,000 kilowatt hours of energy per year, saving approximately 80,000 kilograms of carbon dioxide. The project is an Invest-to-Save project, meaning the costs will be repaid through reducing energy costs and potentially the sale of electricity to the National Grid, before achieving an ongoing saving for the Council.  |

| Unique Screw Pump / Generator project for Olympic Games | |
| |
|
Published May, 2010  Spaans Babcock secures unique Screw Pump / Generator project at training camp location for competitors in the London 2012 Olympic Games Spaans Babcock has been awarded a prestigious project to supply and install four huge Archimedes screw generators by JN Bentley who is the civil contractor on the scheme at one of the training camp locations for the London 2012 Games. The project forms part of a multi-million-pound upgrade of the Tees Barrage white water course to make it one of the best in the world. The improvements involve re-designing the main course, building a second shorter course and installing the Screws to create guaranteed conditions for canoeists, rafters and other white water sports activities. Steve Garcia, Project Manager from British Waterways, responsible for the upgrade, said: "Once completed the new upgraded course will provide the UK’s first fully sustainable white water course." The course has been confirmed as a pre games training camp for Olympic competitors, the upgrade will enable the site to bring some of the biggest water sports events to the Tees both before and after London’s 2012 Games. Spaans Babcock Sales Director Mark Brown has been working on the scheme from the concept stages for around 4 years. He advises that the equipment which they are to install comprises four 3.1 metre diameter 13 m long Archimedean screw pump/generators each of which weighs over 30 tonnes. With all four screws running they will pump enough water to fill an Olympic size swimming pool in less than three minutes. When conditions permit the environmentally-friendly screws will also use excess river water to generate in excess of 130 kW each, making the course sustainable in energy terms.  The company has been supplying, installing and maintaining Archimedes screws in the UK for more than 40 years. With the introduction of the technology to generate electricity a whole new market has developed, a number of systems have already been installed and numerous other projects are either in manufacture or close to finalization. The technology is now being utilized on numerous River Weirs and old Mill sites, the fish friendly design helping with Environment Agency approval. The Teesside project however is unique in that it will be the only installation in the world where the Archimedes screws are used as both pumps & generators. |

Published September 11, 2009 Spaans Babcock in Balk, the Netherlands have received a large order in Abu Dhabi. It concerns design, production and supply of 56 surface aerators for 2 different locations near Abu Dhabi. Despite the global economic recession Spaans Babcock continue to move forward in a positive manner. The equipment to be provided is Spaans Babcock O2Max aerators, which will be produced in Balk. They have diameters of 2.6 and 3 meters and are to be installed in waste water treatment plants where 80.000m3 and 300.000m3 water per day will be treated. Spaans Babcock has carried out several tests for its customer on the O2Max aerators to show the efficiency and oxygen input to the customer.   The design of the O2Max guarantees very high oxygen input efficiency. The excellent mixing and propulsion capacity allows the O2Max to be installed in all types of aeration systems such as complete mix, SBR, oxidations ditches and lagoons. The O2Max can be supplied in two different options. Either as fixed arrangement for mounting on a concrete or steel bridge or as a floating unit. The customer in Abu Dhabi chose the fixed application.  The order size amounts to almost € 2 million and the installation will take place in 2010.

Published June 26, 2009 In a world where durable energy and alternative energy resources are becoming more and more important, Spaans Babcock is also creating solutions to use natural resources to obtain energy. The screw generator has now been introduced successfully worldwide. The screw generator is being installed as a standalone generator. In this application the water flows downwards through the screw. This downward flow in turn causes the screw to rotate turning the generator thereby producing energy. This energy can be used locally (i.e. within a water treatment plant, factory or dwelling) or can be sold to an energy company – often at a premium price.   The new product has already been successfully installed at a number of sites in the United Kingdom. Spaans Babcock has already supplied one of the largest screw generators in the world; the twin screws generate up to 180 kW with a head of 10 metres. Over the next few months several more installations are scheduled worldwide. Due to the environmentally friendly aspect and ability to be used in locations with relatively low head, the screw generator is proving to be an interesting way to generate durable energy. The screw generator is very reliable, requires minimum maintenance, is fish friendly and a high efficiency product. 
Screw generators can be used in any situation with water flows and height differences, i.e. rivers, industrial effluent plants, within or at the outlet from water treatment plants. |

| Surface aerators with draft tubes for deep basin | |
| |
|
|
Besides RAS screw pumps, Spaans Babcock bv has Installed 4 huge surface aerators with draft tubes for the waste water treatment plant in “De Bilt” (The Netherlands).
In the middle of 2007, the organisation “De Stichtse Rijnlanden” decided to build a whole new treatment plant on its old location. Due to limited space they were obliged to construct deep tanks in the ground. Nevertheless, they choose to work with the concept which was applied on the water treatment plant “Leidsche Rijn”, for surface aerators including draft tubes. Together with the consultants, Spaans Babcock bv have assisted with of the design of the plant. The installation has now been completed and all results are in line with expectations! The draft tubes, which have been designed, developed and produced by Spaans Babcock in Balk, are 3,7 metres in diameter and are 5 metres in height. Due to the depth of the basin, draft tubes are utilised. The draft tubes take care of an optimal pumping of the waste water to the surface aerators, where the oxygen input takes place. Technical information: Type of basin: carrousel Depth of basin: 7,5 metres Motor power: 90 kW Aerator diameter: 3000 mm This new installation will be running soon.

| SUCCESSFUL EXCHANGE OF A HUGE (11.000 L/s !!) SCREW PUMP | |
| |
|
The Hoogheemraadschap van Rijnland, one of the biggest water authorities in Holland, after an inspection of one of their main drainage screw pumping stations, gave Spaans Babcock bv the order to replace two of three screw pumps.The Hoogheemraadschap van Rijnland is responsible for the water management of an area in Holland which is 5 meters below sea level and also one of the most populated; hence one of the most important conditions was to ensure that the pumping station stayed in service during the replacement.   The main drainage screw pump station was built by Spaans Babcock in 1977 and was at that time the largest main drainage station ever built, with a capacity of 33,000 l/sec. The Pumping of water was carried out by three screw pumps with a total length of 10 metres and a diameter of 4.30 metres. To achieve this capacity the screw pumps were made with four starts (flights). The timescale to replace the two screw pumps was very tight. The screw pumps had to be manufactured and on site within eight weeks; only four days were available to do the replacement. 
With tight planning and good co-ordination throughout the contract, the project was completed on schedule. Special transport and 200 tonne cranes were needed to remove the old screw pump bodies and to install the new ones. Two specialist engineers from Spaans Babcock managed to install the screw pumps and put them into operation within three days.Because of good cooperation between client and supplier a typical Dutch hydraulic water works has been re-furbished to the total satisfaction of both parties. |
