The Kele Effluent Wastewater Treatment System (KEWT) was developed by Ben Kele during the course of his Master's study at the Central Queensland University. The system is a recirculating on-site wastewater treatment and effluent reuse technology. The wastewater undergoes primary treatment and is then further treated through a lined sub-surface recirculating filter combined with an evapotranspiration area. The mixture of filter materials can be adapted to suit the treatment requirements; the most commonly used components are sand, blue metal, river rock, zeolite, scoria and charcoal.
Mixquip, the division of Teralba Industries that designs, manufactures and imports liquid mixing equipment, has expanded their range of portable Side Entry Agitators with the release of the new 240 Volt Single phase 'RUMMAGER'.
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.
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.
Cost-effective engineering has enabled the City of Poteau, Oklahoma to achieve major savings while undertaking recent upgrades to municipal wastewater treatment facilities
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
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.
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.
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.
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.
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.
