xii UK Focus - Water/Wastewater The Proven Value of Wireless Utility Monitoring
Wireless utility monitoring products from HWM’s Radio-Tech brand have been used by Verco Advisory Services to reduce a major UK food producer’s water consumption by almost 10% and gas consumption by over 5% in 5 months, with projections showing savings of around £1m in only 2 years.
When implementing sustainability improvements, companies need reliable, traceable data to target their efforts effectively and efficiently. It can, however, be difficult to rationalise the expenditure and disruption of installing such a system against results that may seem too speculative or distant. The speed of return on investment from wireless monitoring is substantially quicker than for hardwired systems, and the costs can be easily identified up front to ease and simplify the specification process: there are no potential wiring or access problems when the battery-powered devices can simply be fixed
into place, meaning the most appropriate equipment within budget can be identified and used from the very beginning.
Verco, the energy management consultancy, has been working with its client for several years, focussing in 2012 on improving the company-wide sub-metering of resource consumption across its 15 UK sites. To do this, Verco has used Ecochirp transmitters and Wi5 data concentrators from HWM’s Radio-Tech range, which have been installed to enable rapid, centralised data collection from all areas of the business. The wireless devices were chosen largely because of their modular nature, integrating easily with the Carbon Desktop energy management system and requiring minimal ongoing maintenance and management. Easy to specify, install and expand, they have proven to be effective at providing a visible return on investment in the fastest possible timeframe.
Radio-Tech is one of the UK’s specialist names in remote energy monitoring and smart metering products. The company’s small, battery- powered transmitters are coupled with their ‘Wi5 data concentrator’, which collects local readings wirelessly before sending all the information back via GPRS to the user’s choice of computer or server. For Verco, this approach has provided a quick return for evidence of real savings: a tangible reduction in consumption through targeted measures, significantly reduced spend on utilities and a more thorough and detailed picture of the company’s resource usage throughout its business operations and locations.

25313pr@reply-direct.com Operator Self-Monitoring can Lower Costs
Wastewater represents a cost to business. Hach Lange has produced a report on how Operator Self Monitoring (OSM) can not only reduce discharge and treatment costs but also boost profit by increased product recovery and reduced energy consumption. There are a number of ways in which discharges incur costs. For example, if the discharge is treated at a water company treatment works, the water company will impose a fee.
In recent years, the EA has shifted towards OSM where water companies and processing industries self monitor their discharge and report results to the EA. The frequency of monitoring is dictated by a combination of the risk posed by the discharge and assessment of the quality of the operator's monitoring regime. Operators have a choice; they can either hope that the spot checks are accurate, or they can conduct their own monitoring to make sure that it is.
Self-monitoring can deliver much more than an accurate charge for wastewater; it can create a better understanding of a process and thereby improve efficiency and reduce the risk of discharge consent failure.
LABORATORY ANALYSIS SPECTROPHOTOMETER DR 3900
NEW!
Traceability of Cuvette Chemistry
Sample identifi cation for 100% trace ability using RFID technology. Eliminates errors throughout the analysis process
Automatic method updates From the RFID tag on the cuvette box direct to the DR 3900 Spectrophotometer
Current batch information is instantly available for quality assurance via RFID
The choice of technology is often dictated by the application or physical constraints. While portable equipment for spot checking is often relatively low cost, by nature it may demand sample collection, preparation or preservation and offers less diagnostic information than continuous on line analysers, making it more difficult to identify the onset of process batch issues.
Hach Lange manufactures all of these instruments and the company's technical staff are able to offer advice on the best solution for every application.
Samples can be collected from the waste stream either manually or automatically.

Automatic samplers are able to take samples at various times throughout the process cycle in order to deliver a representative sample. The collected samples can even be refrigerated so that they do not change prior to analysis. However, some samplers offer more sophisticated options. For example, they can monitor flow rates and adjust the sampling frequency accordingly. Alternatively, some samplers are able to monitor water quality in the waste stream and take samples when readings reach specified limits or alarm levels.

Collection Options For Effluent Samplers Aquamatic Ltd
automatic wastewater sampler equipment manufacturers, have 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.
Aquamatic wastewater samplers are in daily use around the world, in applications from sewage treatment works to process plant to food manufacturers. At the heart of all Aquamatic samplers is the unique 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).
