Disinfection of water is a major public health concern and it is essential to reinforce protection against microbial contaminants. In Europe, strict regulations have been employed by the Brussels Commission to limit the amount of micro-organisms and chemical substances permitted in water. The Surface Water Treatment Rule (SWTR) adopted by the US Environmental Protection Agency (EPA) also regulates turbidity performance criteria and monitoring requirements. Analytical Technology's Q45WQ Water Quality Panel ensures that levels of disinfectant are in compliance with these legislations.

The innovative Q45WQ Water Quality Panel allows constant on-line monitoring of any remaining disinfectant.

Many water companies have concerns about the possibility of deliberate contamination of the water supply. Work carried out by the US EPA (reference and report available on request) has shown that simultaneous monitoring of common water quality parameters can be used to 'fingerprint' a water supply. Many common toxic contaminants cause spikes in the data from monitors such as conductivity, pH, ORP, chlorine etc.

This new panel is capable of monitoring a number of these key parameters. A reagentless monitor measures residual chlorine. An LED or white light based turbidity monitor can cover ranges form 0-0.4NTU all the way up to 4000 NTU. The sensor is stable, offering self-adjusting electronic zero to monitor turbidity with an extensive range. Conductivity is measured by a 4 electrode sensors to cover a wide conductivity range of measurement without the need for multiple sensors. The Q45WQ Water Quality Panel is capable of offering particle count data ranges from 2-400 microns. It also can provide pH data ranges from 0-14 and ORP data between-1000 to +2000 mV.. A single combination ion selective electrode is used to measure fluoride ranges from 1000 PPM down to 0.1 PPM. Meanwhile, a rebuildable cartridge style membraned sensor is applied to measure dissolved oxygen ranges from 0-20 PPM. In addition, the panel can monitor the level of inlet pressure from 0 to 200 PSIG and sample flow rate between 0-30 GPH. The panel can be used to monitor all the vital water quality parameters in a single unit.

Dissolved ammonia monitor enables
effective control of wastewater systems

The Q45N Dissolved Ammonia Monitor achieves continuous, on-line monitoring of wastewater. Continuous monitoring of ammonia in wastewater is becoming increasingly important for plant operations and process control. Analytical Technology's dissolved ammonia monitor enables companies to effectively control the levels of ammonia in their effluent.

The innovative Q45N monitor from Analytical Technology offers a completely novel approach to on-line monitoring of ammonia, which is simpler to use and more stable than conventional monitoring equipment. The levels of ammonia in wastewater effluent must be strictly controlled as excessive levels of the substance can be toxic to animal and plant life. Acceptable levels of ammonia in wastewater are set out by the Environment Agency in the consent to discharge awarded to organisations. In order to comply with these regulations, it is essential that companies utilise effective and reliable monitoring instrumentation.

Q45N Dissolved Ammonia Monitor.

Traditional ammonia monitors are expensive, complex and labour-intensive instruments which use automated versions of ammonia selective ion electrodes methods better suited to laboratory measurements. The Q45N dissolved ammonia monitor from Analytical Technology overcomes these problems by using reaction chemistry to convert ammonia in a solution to a stable monochloramine compound, equivalent in concentration to the original ammonia level. The chloramine concentration is then measured with a unique amperometric sensor that responds linearly to chloramines while eliminating interface from excess free chlorine in solution.

Reagents are inexpensive and usage is low, and as a consequence the monitor offers a very low cost of ownership. The monitor has two 4-20mA outputs programmable for free ammonia, total ammonia and monochloramine concentration. This allows all the important parameters to be measured on a single instrument. The amperometric sensor also provides excellent repeatability.

A portable monitor for fast and effective
on-line measurements of chlorine in water

Analytical Technology's portable Q45H/62 Residual Chlorine Monitor is an innovative battery-powered monitor that allows on-line control of chlorination systems without the use of reagents or mains power and enables installation directly into water and wastewater networks. The Q45H/62 monitor from Analytical Technology is available in two versions: a free chlorine monitor for drinking and cooling water systems and a combined chlorine monitor ideally suited for chloraminated drinking water. A free of charge datasheet is available at: www.analyticaltechnology.com

The portable Q45H/62 monitor can be installed close to point of use, allowing precise measurement of chlorine levels. Unlike traditional colorimetric and most amperometric monitors, Analytical Technology's battery-powered Q45H/62 system utilises a membrane-covered polarographic sensor which does not require the addition of chemical reagents. The sensor contained in the new portable chlorine monitor has a response time of up to 10 times higher than that of conventional sensors, enabling the monitor to carry out reagent-free chlorine measurements for most pH values found in the UK water industry. For applications with variable pH values, the new portable monitor has an optional pH compensation feature to eliminate free chlorine error caused by process pH drift. When the correct sensor is used, there is an extended response to chlorine at high pH levels, allowing pH correction to be employed over a much wider range.

The long-life battery contained in the monitor enables implementation even where no external power is available, meaning that it is ideally suited for water survey measurements and network monitoring. Easy to install, the portable monitor requires no additional plumbing and is provided in a shock-proof, water-resistant casing. The monitor is complete with quick release push fittings and self sealing valves. This means that the monitor is easy to install and keeps the sensor wetted when not in use. The monitor is available with two data logging options. The simplest option is a logger that downloads data to a laptop or PC via a cable. Analytical Technology also offers data logging via a GSM system which uploads data to a secure web site for download from anywhere with an internet connection.
