Waste Water Treatment
High efficiency pump control systems
Water companies are under unprecedented pressure from rising
energy costs as well as legislative and climate change. The use of
variable frequency drives are increasing in popularity at water and
waste-water facilities, where the greatest energy draw comes from
pumping and aeration—two applications particularly suited to
variable frequency drives. For more information see our article

Front End Variable Frequency Drives) on Pumps
& Systems pump-zone.com
Developing strategies to reduce operating costs while optimizing
the performance of assets is critical. Control Techniques provide
new solutions to enhance connectivity, reduce energy consumption,
minimize downtime and to react intelligently to real problems as
they occur.
Since variable frequency drives work
with most three-phase electric motors, existing pumps and blowers
that use throttling devices can be retrofit with these controls.
Additionally variable frequency drives can be specified for new
applications.

Optimized drive solutions for the Water industry
As market leaders in intelligent drives, Control Techniques’
drives present a new approach to managing your assets. Our products
combine high reliability, compact size and the flexibility to
incorporate additional functionality such as intelligent pump
control, I/O for instrumentation and TCP/IP based telemetry
solutions within the drive.
Our variable frequency drives
allow you more precise control of processes such as water
distribution, aeration and chemical feed. With the inclusion of
variable frequency drives the pressure in your water distribution
systems can also be maintained to closer tolerances.
Control Techniques’ Intelligent Pump Control drive system
Control Techniques’ Intelligent Pump Control (IPC) system
delivers measurable improvements in pumping reliability, up-time
and performance. In real installations it significantly reduces the
costs associated with operating these assets while improving
throughput and availability.
Solutions to real problems
A long standing pumping problem suffered by water companies is
that of ‘ragging’, the fouling of pump impellers in waste water
systems. Manually clearing the problem is a costly and unpleasant
task requiring a maintenance team and frequently a crane. Downtime
may extend to several days during which time the back-up systems
are under additional pressure. A total system failure can result in
effluent leakage with implications for the environment, human
health, clean-up costs and breaches of legislation. Control
Techniques’ IPC system accurately monitors pump performance by
“live” continuous measurement of torque producing current, plus
flow and pump speed where appropriate. The live data is compared to
measured values taken during commissioning, plus expected pump
profile characteristics. Due to the precise nature of the pump
monitoring programme, any “out of profile” performance feedback
triggers an early warning indication of potential pump
ragging/blocking. This initiates an automatic drive based cleansing
cycle program to help clear the pump impeller. The system is also
able to schedule real time pipe scouring cycles, detect
deteriorating flow and potential impeller wear.
Electric motors consume an estimated two-thirds of the
electrical energy used in industry. Control Techniques drives not
only improve processes, they also significantly reduce
energy consumption and play a crucial role in
improving the overall energy efficiency of process plants.
Reducing energy costs and improving processes
Installing variable speed drives to control pump flows to match
operational demand, can significantly contribute to a reduction in
energy consumption and improve process control. In some
applications, intelligent systems are able to further reduce energy
costs by operating during off peak periods. Control Techniques
drives provide a kWh reading to allow the energy savings to be
easily monitored.
