Monitoring service enhances water treatment operations Elga Process Water has introduced AquatrendTM, a plant monitoring service that aims to help plant engineers understand the myths and realities of water treatment. Elga’s water treatment specialists will work with the customer’s plant engineering team during a detailed audit of the water treatment plant, comparing current performance with the original design and future requirements. The team then identifies a set of Key Performance Indicators (KPIs) which will be monitored, such as raw water quality, treated water quality, treated water volume output, wastewater per unit of treated water, and membrane cleaning frequency. For each KPI the team will set a normal or target value, an early warning level and an action level. The expert can then monitor these KPIs in a variety of forms such as electronic data logging, traditional log sheets or statistical process control
Once the AquatrendTM has collected the data, the process engineers from Elga Process Water interpret that data to determine how a plant is really running.
(SPC) charts, for the customer to collect data. If the customer has electronic data acquisition or datalogging facilities then Elga
can monitor the plant remotely, using either telephone or internet access. This information is then reviewed by an Elga
specialist who reports regularly on trends and outlines the actions required. www.elgaprocesswater.com
Range of water Analyser helps meet purification systems for European drinking laboratory applications water regulations Anachem has launched the Anachem HF NW range of water purification systems. The units have been designed to provide high quality water for all laboratory applications and to ensure that pure water is on hand whenever needed. According to liquid handling and bioanalysis specialists, Anachem, the HF NW range provides Type 1 18.2 MW.cm water direct from a tap water feed and integral high flow rates as the reverse osmosis function produces up to 30 litres/h. The system can also result in money savings as there is
no need for expensive prepurification equipment, and with two different grades of water from one unit, bench space can be saved. Four different versions of the NW series (basic, UV, UF or VF) allows users to choose the system that produces the quality of water required for the application. Anachem can service and carry out a programme of preventative maintenance on the company’s laboratory water systems and, if required, will change the cartridges. www.anachem.co.uk
Severn Trent Services’ Capital Controls® CL1000B bufferless residual chlorine analyser has been developed to help meet European drinking water regulations. The CL1000B has been tested many times, and in one eightmonth trial performed by an independent third party for a water company, the CL1000B was found to cope with a wide range of pH fluctuations in water samples compared, to the performance of the other technologies being evaluated. The amperometric-based CL1000B is designed to
continuously analyse free chlorine or other oxidants for water, wastewater and other process water applications using a three-electrode arrangement. This arrangement establishes a constant potential on the working electrode to provide accuracy, stability and sensitivity of one part per billion. Severn Trent says the CL1000B’s on-screen instruction and self diagnostics simplify user operation, and the constant, direct-drive electrode cleaning system eliminates the need for frequent instrument recalibration. www.severntrentservices.com
