Ozone monitor improves drinking water
quality
Bristol Water has chosen the innovative Analytical Technology Q45H/64 Dissolved Ozone Analyser for the on-line monitoring and control of ozone levels in drinking water
Bristol Water uses dissolved ozone for the disinfection of potable water Offering ultimate flexibility, ease of use and accuracy, the ATi analyser used for on-line monitoring and control has reduced the amount of energy required for the ozone disinfection process, thus minimising the associated costs while also improving the quality of the drinking water produced by Bristol Water, which currently ranks among the best in the world

Ozone is the strongest stand-alone oxidiser currently available for water treatment.
It breaks down pesticides, kills micro-organisms and removes unwanted colour leaving no taste, odour and most importantly no dangerous chemical residues.
It is exceptionally quick-working, with the oxidisation process taking a staggering 2 seconds.

Traditionally, ozone production has been monitored and controlled using Redox analysers, spectrophotometers, amperometric monitors and colorimeters, all of which demonstrate significant shortcomings.
Lack of sensitivity, expense, complication of use and inefficiency are just some of the criticisms levelled at them.
The ATi Q45H/64 dissolved ozone monitor has been engineered to provide accurate and reliable ozone measurements down to PPB levels.
Accurate calibration using a ppb traceable titration method ensures the monitor accuracy.
Additionally, the monitor requires minimal operator attention and has the lowest cost of ownership compared to all other dissolved ozone monitors available on the market.
With the assistance and expert input of ATi, Bristol Water has been able to modify the monitors on site leading to considerable reduction of oxygen consumption from 6 tonnes daily to between 3 and 4 tonnes whilst maintaining the improvement in the water treatment process.
Such large scale reduction in ozone demand has realised massive savings for Bristol Water, enabling them to invest in further ways to improve their process.
A spokesperson at Bristol Water commented that: "Reaching and maintaining an exemplary level of drinking water quality demands that we invest heavily and constantly in new technology to ensure standards are preserved and to increase efficiency and cost savings.
The reduction in ozone usage from six down to four tonnes per day is down to several factors:- A new diffusion system and dosing controls which disperse the ozone in a more uniform pattern.
The result is a more stable residual which is accurately measured by the ATi instrument.
The ATi Q45H/64 dissolved ozone monitor has proven an intelligent, dependable tool capable of providing accurate data easily and efficiently".
