applications from sewage treatment works to process plant to food m a n u f a c t u r e r s . At the heart of all Aquamatic samplers is the Aquacell module, which uses a wide-bore vacuum pump system to extract the sample from the effluent, ensuring that a truly representative sample is taken. All Aquacell wastewater samplers are MCERTs certificated, and Aquamatic is approved to both ISO9001 and ISO14001, as well as CEMARS (Certified Emissions Measurement and Reduction Scheme).

Compiled by Water UK for the industry and its stakeholders and published by Faversham House, Who's who in the water industry 2014 is an invaluable source of information for the industry. The 41st edition includes: • Updated and expanded information on water companies and authorities, regulators, training and research groups, government departments and international contacts • Biographies of prominent individuals in the industry and a convenient directory of suppliers of products and services • An alphabetical Buyers' Guide section links with an A-Z name and address section listing suppliers to this key market A set of product demonstration videos has been posted on the Analytik Jena UK website as well as the company's YouTube channel showing a variety of products in action, covering UV- Vis and atomic absorption spectrometry, TOC analysers and elemental analysis. The company said the videos provide a really useful introduction to the instruments, highlighting their range of capabilities and ease of use. UV-Vis instruments covered are the versatile SPECORD 600 and SPECORD PLUS. With Analytik Jena celebrating 50 years of SPECORD manufacture, these videos highlight the range of capabilities from the SPECORD® 600 diode array instrument to the SPECORD PLUS range of double beam spectrophotometers. Three videos showcase the wide range of atomic absorption spectrophotometers from the novAA400P with its unique transverse graphite furnace design to the contra series of high resolution continuum source AA spectrometers for flame, hydride and furnace analysis which closes the gap between ICP and AAS. The contrAA series provide innovative analysis options since the continuum source provides immediate access to all elemental lines. AquAmAtic , automatic wastewater sampler equipment manufacturers, has added new options to their sampling container range with the addition of these tough, secure screw-top containers. Designed to fit with Aquamatic's stationary or portable sampler range, the new containers are rugged HDPE in construction, and provide customers with an easy use, easy change option for collection and storage of representative effluent samples. The new containers also come complete with a contamination shield to prevent atmospheric dust or other airborne contaminants from reaching the sample. The new containers are available in 2.5, 5 and 10 litre capacities. Clamp-on flow switches eliminate algae micronics Clamp-on Flow Switches provide cost-effective solution to eliminate algae growth problem on flow monitoring of wash-water flow at Wessex Water A problem had arisen where the flow sensors being used for confirmation of wash-water flow to plant and equipment were found to be growing algae. The thermal dispersion flow switch and the wash- water in the systems used either final effluent from the plant or partially treated water from some other point in the treatment process. The water content plus the increase in temperature on the probe was producing a food-rich and warm place for the propagation of algae. This affected the thermal dispersion from the probe to the point where the probes no longer detected flow. Removal from the pipeline would traditionally involve the isolation and draining of the wash-water lines. Trant Construction, which undertake civil mechanical and electrical projects for major UK and overseas water companies were called in. It identified that a non-intrusive, cost-effective and simple to operate sensor that would not be subject to fouling was required. Various alternatives were considered until Dave Rich, of Trant Construction, discovered the Micronics DFS-ll Doppler Flow Switch and agreed with the client to trial one unit for pipelines ranging from 32mm to 300mm, dependant on the velocity of flow through the pipework. The DFS-II is designed for "dirty" liquids. The sensing is non-invasive, working by injecting high frequency sound through the pipe wall into the flowing liquid. Acoustic pulses are continuously reflected back to the sensor and the DFS-II measures a frequency shift to calculate flow velocity. It controls flow without any drop in pressure, no sensor fouling and minimal maintenance. Installation takes just a few minutes because there is no need to cut into pipes resulting in a major saving in time and plant outage. T h e trial was successful a n d W e s s e x Water is now using the Micronics flow switches for most applications, including not only wash-water but pump discharge monitoring where some non-return valves had proved to be unreliable. the clamp-on flow switch Videos show product range in action pipe sensor is 'unmatched' field trials and fully operational installations of Nivus' pipe sensor have been running for more than three years with zero failures, according to the company. Velocity measurement accuracy is ±1%, which Nivus said "is unmatched in its field". First introduced to the German market in 2008 and then the UK Market two years later, it received official MCERTS status in 2012, and is fast becoming recognised as the preferred solution for the validation and / or replacement of Mag meters in the UK. The robust stainless steel outer casing and compact design is far easier for handling, particularly in confined spaces, and suitable for diameters ranging from 80mm. The sensor is situated at the very tip, which is the only part to sit in the flow so minimising any ragging or debris failures with the added advantage of being self- cleaning, and can be installed to any pipe material and dependant on application can be placed at almost any circumference point for a full and accurate reading. The Pipe Sensor uses the Nivus Cross Correlation principle and requires no calibration. Being versatile it can deliver flow velocity and / or level accuracy whether mounted on a boat system for open channel monitoring or as a pipe insertion meter. The Cross Correlation technology is an ultrasonic flow measurement technique. By scanning reflectors within the water (particles, gas bubbles or minerals), an ultrasonic impulse is saved as an echo pattern. Further scans follow milliseconds later. Correlating all signals allows flow velocity to be measured either in full or partially filled applications. Nivus enabled the pipe sensor to connect to the NFP transmitter for smaller applications to keep solution costs low. It can be fitted in hours, rather than the days of site disruption with no interruption to the flow. The Pipe Sensor comes in standard length sizes of 20, 30, and 40cm, and when access space is confined extendable rods can also be fitted. the sensor is suitable for diameters ranging from 80mm aquamatic adds to sampler range Aquamatic wastewater samplers are in daily use around the world, in the containers are available in capacities ranging from 2.5 to 10l
