Water/Wastewater New Portable Water Quality Monitoring System
Palintest (UK) is launching the new Macro 900 Water Quality System for multiparameter water quality monitoring. Designed to combine portable hi-tech functionality with excellent ergonomics in an easy-to-use package, the Macro 900 WQS is particularly well-suited for environmental surveys, aquaculture applications and wastewater and surface water monitoring.
The Macro 900 Meter forms the core of the system. It is completely waterproof, battery-powered and includes three dimensional GPS positioning as standard, storing up to 1900 full data sets of results. The high-contrast LCD screen is backlit for use in low light environments and the rubberised function keys are designed for effective use even with wet or gloved hands.
A full range of Macro Accessory Probes allow the system to monitor a wide variety of parameters, including: pH, conductivity, TDS, turbidity, depth and both optical and galvanic Dissolved Oxygen (automatically compensated for atmospheric pressure and salinity). All Macro Accessory Probes are simple to maintain, manufactured in marine grade aluminium and only 48mm in diameter to ease use in narrow boreholes.
In addition to the Meter and Probes, the Macro 900 Water Quality System comes complete with a full range of accessories and consumables, including: extension cables for the Probes, flow cells, MacroLink software, calibration solutions and replacement probes/caps.
Reader Reply Card No. 152 Monitoring at Water Treatment Plants
Monitoring multiple sensing points including fill level, pH, conductivity, and flow – often from varied locations in a large water treatment plant – can be a challenge. With four analogue inputs, a single SureCross Node can easily centralise and transmit critical monitoring information from multiple Sensors or controllers.
Banner Engineering’s (Belgium) unique power management capability enables a single Node equipped with a FlexPower optimised QT50U or T30UX ultrasonic analogue sensor (level detection) to operate for years on a single DX81 battery power supply.

LAR Process Analysers (Germany) and filter-free QuickTOCultra analyser uses a unique thermal oxidation technique at 1200°C. At this high temperature raw waste water samples, including particles, are fully oxidised and salts are easier to handle.
This method does not require dilution, catalysts or filtration. A sample is directly injected into the reactor, where the oxidised organic substances are measured with an NDIR detector. Due to the enormous expansion of the injected sample, the melted salts are blown out of the reactor and collected in a specially designed reactor foot.
Blockages, defective reactors, replacement parts and long downtime belong to the past. The QuickTOCultra analysers have very low maintenance, operational costs and high availability, as a result of its construction and combustion technique.
Operating with salt contents as high as 20% and the possibility to measure up to six streams makes these analysers most suitable for challenging waste water applications.

Pulsar Process Measurement (UK) have supplied seven of their latest sludge blanket monitors, Sludge Finder 2, to Wessex Water for use at Christchurch STW, replacing outmoded, unreliable dipping probes.
The final settlement tanks run at an ideal sludge blanket level of 15 – 20% of tank depth, controlled by the use of RAS (Return Activated Sludge) valves. Before the Sludge Finder units were installed, the dipping probe measurement system had become unreliable, readings often including ‘spikes’ or ‘flatlines’ that would activate the RAS valves unnecessarily, using excess energy and making it more difficult to control the sludge blanket. The dipping probe system is mechanical, and the ageing system had become unreliable and prone to breakdown.
Sludge Finder makes use of Pulsar’s echo analysis expertise, allowing very accurate measurement of changes in sludge blanket. The self-cleaning ‘Viper’ transducer only needs to dip just below the surface of the liquid, signalling back to the Sludge Finder controller.
The improvement in control of the RAS valves has led to a 30% reduction in power consumption. The Sludge Finder signals to a local PLC for control of RAS valves and also on to the data display system, which can be accessed remotely for monitoring and trending.

New Technology Makes Segmented Flow Analyser Compact and Easy-To-Use
SEAL Analytical (USA) has launched the 'AA1' – a fully automated analyser employing new technology based on segmented flow analysis for rapid, accurate, precise analysis of parameters such as Ammonia, Phosphate, Nitrate, Nitrite, Total Nitrogen, Total Phosphorous and Chloride.
Designed for reliability and simplicity, the AA1 is fully automatic with up to two separate channels analysing two parameters simultaneously and performing up to 120 tests per hour.
Instrument control and data acquisition is performed with intuitive, easy to use 'AACE Lite' software, offering over 1,000 analytical methods meeting USEPA, ASTM, ISO and other international regulatory standards.
In order to achieve low detection limits and excellent reproducibility for the AA1, SEAL Analytical's German facility has designed and manufactured an innovative pump and brand new heating module; details are available at
www.seal-analytical.com . Smartphone users can access the AA1 brochure directly with the QR code opposite.
