IDS are ABB Inverter specialists. We specify, install, commission, repair, service and hire variable speed drives.
Anglian Water was facing challenges with their inlet screws, which consumed between 4,000 and 5,500 kWh per day due to reliability issues. These screws were manually operated to mitigate these issues, leading to higher energy consumption. Each screw operated continuously, using soft starters for 24 hours a day. Project Initiation Anglian Water approached IDS to […]
Severn Trent Water are saving 14 tonnes of CO2 per annum by applying an inverter to an Archimedean Screw. Blaise Ford from IDS worked with Bill Edwards and Lee Tuckwell from Severn Trent Water, to apply inverter technology to an Archimedean Screw. At the Severn Trent Water Netheridge site there are three Archimedes screws, Duty/Assist/Stand-by, […]
Weedscreen cleaners are essential for rural pumping stations pumping water out of dykes. Without them, the pumps would get choked with weeds and pumping performance would fall with the risk of local flooding. It is important that these weedscreen cleaners are kept in efficient operation. The alternative to a weed screen cleaner is an expensive […]
ABB variable speed drives improve energy efficiency with payback of less than three years at a Severn Trent Water sewage treatment works. Severn Trent Water is saving 15,000 kWh per year after installing two ABB variable speed drives at its Edwinstowe filter bed sewage treatment works in Nottinghamshire. The sewage treatment works includes a stone […]
Sludge Density Pump Control or Reactive Pump Control (RPC) Introduction Sludge is created when a liquid containing solids is settled. Typically, this can be in PSTs (Primary Settling Tanks) or Humus Tanks in sewage treatment works. Alternatively, it can occur in mineral processing plant in clarifiers. The pumps that take the sludge from the bottom […]
Our engineers are used to visiting large industrial plants, remote water treatment sites as well as mines and quarries. Whilst the scenery en-route to these premises can be breathtaking, it made a welcome change for us to visit the picturesque seaside town of Weymouth. SEA LIFE Weymouth is set across a 7 acre Park with […]
Archimedean Screws are efficient, low-head, high-volume pumps that have been used for thousands of years. They are particularly useful for pumping liquids with high solids content. Previously it has been thought that inverter control of these Screws didn’t save energy, but we, at IDS have engineered a solution that does produce energy savings, as well […]
Extract fans are in common use to remove harmful dust and fumes or transport material within factories. Whatever their use, they rely on duct air velocity to ensure the material is kept in the airflow and does not settle out and cause a blockage. An Irishman, Sir George Stokes first developed a theorem that related […]
Archimedes’ Screws (normally called screws) are widely used by the water industry, usually used for pumping at the inlet of Water Recycling Centres to lift the flow and allowing a subsequent gravity fall through the works. These screws are known for their efficiency, simplicity, ability to handle high suspended solids and capacity to cope with […]
Inverter Drive Systems, Managing Director, Blaise Ford, talks about the benefits of the Reactive Pump Controller (RPC) exclusive to IDS. Reactive Pump Controller Video In sewage works, the pumps on the primary settling tank are normally controlled by timer alone and by definition they pump more sludge than you need to. IDS use the features […]
