Huber Technology was commissioned by South West Water to improve the inlet works facility that serves the town of Exmouth in Devon

outh West Water wanted to upgrade its inlet works facility that Sserves a major area of Devon. The site is responsible for treating sewage from the town of Exmouth, the county’s fifth most populous urban area. With a population of around 35,000 people, it lies at the western end of the Jurassic Coast conservation area. The inlet facility featured a balance tank which had become increasingly overloaded with build ups of rag and screening. This was threatening the efficient functioning of the entire works and required improvement. Engineering consultants Tecker had been tasked to oversee the works and approached Huber Technology. The firm is a supplier of proprietary stainless steel wastewater treatment solutions serving both municipal and industrial markets.

Pumps are frequently blamed for the air blockages that cause problems for sewage stations and mains. The fault often lies elsewhere, cautions Hydraulic Analysis Limited’s Glyn Addicott

esearch shows that an estimated 10% of sewage pumping stations and rising mains in the UK are suffering from air locking due to inadequate air release facilities. RAir blockages typically result in the following issues: l Pressure at the rises gradually when the pumps start l If centrifugal pumps are installed, the design (consent) flowrate is not achieved during a normal pumping cycle due to the air pockets l High pressures are created by the trapped air with frequent bursts occurring l Sedimentation due to low velocities l If positive displacement-type pumps are installed, pipeline operating pressures can rise to more than double the design pressure. Bursts are particularly common in uPVC pipelines as this material is prone to fatigue failures – there are design limits relating to the pressure variations which uPVC mains can be subjected to when pumps stop and start.

POLLUTION THREATS Pollution fines for assets that experience multiple failures can exceed £0.5 million, with Category 2 pollution events and prosecutions becoming increasingly common. The solution to preventing pollution incidents lies in practical engineering to identify, address and resolve the cause of the pipeline failures. While it is accepted that these aged rising mains need replacing, the current scale of the undertaking makes it unrealistic over the next decade. Not all vulnerable rising mains are necessarily at the end of their useful life. These mains are fatigued and operating outside of their design envelope due to air blockages causing flow restrictions and higher pumping pressures/surge n HAL has developed the Pipeline Condition Monitor (PCM) pressures.

“Many pump systems are far less efficient than they may appear. Often when specifying, designers simply multiply the catalogue efficiencies for each component”

Furthermore, EN 50598-2, a relatively new standard for VSD efficiency, defines that manufacturers should publish their figures based on their default factory setting. Manufacturers use different default settings. ABB uses 4 kHz as a default switching frequency; other manufactures choose to use 2 kHz. This lower switching frequency improves the figures the manufacturer can publish for the VSD efficiency. In practice, the system efficiency is worse. Secondly, simply connecting components together overlooks some fundamental lessons of physics which cause them to react with each other in unexpected ways; adding a VSD or a PQF (power quality filter), or passive filter can impact on system efficiency. With these insights, utilities planning greenfield sites can avoid energy use disappointment. But what about existing electrical systems? The good news is certain components can be fine-tuned, replaced or adjusted to improve the overall efficiency. Additional savings can be achieved by ensuring the individual components of a pump’s electrical system are optimised.
