Using sewage for green power

02 February, 2006

Green energy - power produced and harnessed during the treatment process in some sewage works in the United Kingdom - is helping to run operations within them.


Pump/pressure system selection guide

Davey Water Products has released Issue No 15 of its comprehensive Product Selection Guide.


Peristaltic hose pumps

27 January, 2006 | Supplied by: http://www.h2orx.com/

The PeriFlo range of Peristaltic Hose Pumps is now distributed by H2O Rx. The range includes 20 pump models, complete engineered pump systems and UL listed custom controls.


ISC Signal Isolator

26 January, 2006 | Supplied by: Innovec Controls Pty Ltd

The ISC Signal Isolator is a single channel universal isolating transmitter providing true three-way galvanic isolation up to 2000 VRMS. The input signal is isolated from the output by a microprocessor controller optocoupler. The standard instrument accepts a 4-20 mA and 0-10 VDC input signal and produces a scaleable 4-20 mA or 0-10 VDC output signal with an accuracy of 0.1%. Final calibration is achieved using the front of instrument accessible 15 turn zero and span potentiometers.


Upgrading a wastewater treatment plant

03 January, 2006

Cost-effective engineering has enabled the City of Poteau, Oklahoma to achieve major savings while undertaking recent upgrades to municipal wastewater treatment facilities


Gate required to divert sewage

03 January, 2006

Lower Murray Water (LMW) in Mildura required a gate to divert sewage flows to catchment ponds. Darren Bennett from LMW was concerned with the traditional square bottom penstocks that had previously been used to control water flows


Mixing solution

19 December, 2005

Pulsair is a technology that delivers an efficient, cost-effective, low-shear method of mixing. The system injects a powerful pulse of compressed air (or gas) into the vessel in a way that creates a vertical circular mixing motion and the contents of the tank are quickly blended into a uniform mix. The mixture can be held in suspension with sequentially-timed pulses that require little expense of energy.


Activated sludge respirometer

19 December, 2005 | Supplied by: http://www.novasys.com.au/

The latest version of the Strathkelvin Strathtox respirometer can tell users quickly, simply and clearly when the bacteria should be fed less, aerated less and loaded more in an activated sludge or IDEA treatment plant. This is done by measuring their actual respiration rate.


Contacting conductivity sensors

19 December, 2005 | Supplied by: http://www.ams-ic.com.au/

BAT Contacting Electrode Conductivity Sensors are offered in a range of temperature, pressure, chemical compatibility and installation configurations.


Sludge and viscous products heat exchanger

28 November, 2005 | Supplied by: Teralba Industries

Teralba has expanded its range of Dimpleflo Monotube Heat Exchangers to include an (8") 200 mm inner tube.


Level limit detection in bulk solids

25 October, 2005 | Supplied by: http://www.au.endress.com/

The storage and handling of bulk materials such as grain, flour and plastic pellets can be a high-risk activity and demands accurate and reliability level limit detection. A poorly designed high level limit switch may cause an overflow or a spill leading to wastage with an adverse financial and environmental impact. On the other hand, unreliable low-level measurements may cause inventory problems that negative affect a company's bottom line.


Transmitter for measurement and control

25 October, 2005 | Supplied by: http://www.eutechinst.com/

The Eutech Alpha 500 series industrial 2 wire transmitter isolates its input source from its 4-20 mA output to prevent electrical noise and leakage from interfering with the output signal and eliminates crosstalk between multiple transmitters in the same loop to ensure a stable and reliable measurement and control system.


Low power digital camera

25 October, 2005 | Supplied by: http://www.campbellsci.com.au/

The CC640 digital camera is a low powered, digital camera designed to operate either standalone or in conjunction with a data logger and telemetry system. As a standalone camera and image storage device, it can operate automatically via an in-built timer or be triggered by an external 5 V source. Images are stored on a flash card for later retrieval by PC.


FL-3-H dissolved oxygen meter

25 October, 2005 | Supplied by: Process Control Services Pty Ltd

Environmental Instruments, LLC has introduced its model FL-3-H handheld dissolved oxygen meter. There are no membranes or electrolyte and the sensor is not damaged by direct or indirect sunlight. It is a fast responding handheld DO sensor and the keypad functions are simple to use, and the ABS instrument enclosure is waterproof, dustproof, chemical resistant and floatable.


Inductive conductivity and temperature transmitter

26 September, 2005 | Supplied by: http://www.practicalcontrol.com.au/

The series of JUMO CTI-500 conductivity and temperature transmitters uses an inductive measurement technique to provide virtually maintenance-free measurement of temperature-corrected conductivity from 0-500 micro Siemen/cm to 0-2000 milli Siemen/cm. The temperature measurement range is from 0 to 150°C with a fast response in-stream stainless steel probe and an internal, slower response probe option not in contact with the liquid.
