Have A Problem?




London drain jetting

Sunday, July 3rd, 2011

One of the best tools in the London drain cleaning company’s arsenal is the high pressure water jet. If you have a drain blockage, a drain cleaning company may be able to solve the problem quickly and efficiently by directing a jet of hot water at high pressure into the drainage system. In most cases this is enough to break up the offending clog and the remnants can simply be removed at the next manhole cover. Drain jetting is a simple process but should only be carried out by drainage professionals. Some of the jetwashers you can buy to clean your driveway are not up to the job of jetting a drain and work at significantly lower pressures. The drain cleaning company also use attachments on their drain jetting equipment, which lets them get ‘up close and personal’ to the blockage so it can be removed easily. If drain jetting alone is not enough to clear the blockage, the drain cleaning company may use CCTV survey equipment to get more information on what the cause of the problem may be. Other possible reasons for a blockage include root intrusion and a collapsed drain.

New centrifuge at United Utilities Carlisle treatment works

Friday, July 1st, 2011

United Utilities has just revealed their latest way to cope with people’s ‘business’. They have just installed a centrifuge device at their Carlisle treatment works which pulls water out of the treated sewage at 36 revolutions per second. When the load has been spun the remnants are a crumbly deposit which can be used as a soil conditioner for farming. The process controller at the plant Robert Corry commented:

"Recycling is nothing new to us. We've been doing it for decades. But while the basic process of bacterial breakdown hasn't changed, new technology gives it a real boost, "We used to have to squeeze the water out of our treated solid waste using a big press. The centrifuge is more automated and 25% more efficient than the old pressing method."
The new centrifuge is still undergoing trials but should be fully operational soon. The system has cost United Utilities £17m and comes alongside a new pumping station and a new inlet screen. The next upgrade for the site will be new bridge scrapers and tracks which will cost the company in the region of £1.4m.
