Exclusive New Pump Control For Uk Water Industry
Posted on January 22, 2008 - Filed Under Business
Twenty percent of all energy consumed in the UK is used for pumping applications; much of this will be sewage and clean water pumping stations.
UK water authority companies spend billions of pounds each year upgrading water/waste water treatment works as well as pumping system applications.
Pumping stations are used to externally pump raw sewage / water from one location to another. Transportation is usually assisted by gravity from location to a lower location. These pumps are usually controlled by a small control panel which relies on process instrumentation to measure functions such as pressure, flow and level.
A typical pumping station arrangement can be broken down into the following components;
• An inlet pipe feeds sewage into a collective wet well. Inside the wet well there may be an ultrasonic measuring the level using ultrasound technology. Inside the wet well there is usually a backup emergency float which forces all pumps to run if an emergency high level is reached.
• A number of pumps (usually two but occasionally a third). These pumps are located outside of the well, usually known as the dry well. Either side of the pump is a non return valve to stop water / sewage traveling the wrong way.
• There is usually a ventilation pipe located at the top of the dry well venting out any collected gases.
• The pump pumps the water / sewage up the rising main to the top of the higher location where gravity can then take its place once again.
All modern UK pumping stations house a telemetry section which allow a number of signals and alarms to be sent via comms. Typical signals include: high level alarms, mains power failure, pumps running/stopped/failed, intruder alarms etc.
