The industry is currently being driven to increase its focus on efficiency and innovation, in order to operate at the highest level of environmental protection.
Anglian Water, in collaboration with ATi and Aquadose, has taken a step forward to improve the efficiency and effectiveness of its de-chlorination process, working to reduce the likelihood of residual chlorine entering water courses during emergency works or weather events.
To ensure a consistent standard and quality of water, assets, infrastructure and processes must be carried out within the use of stringent environmental parameters. This has driven the industry to increase its focus on efficiency and innovation to operate at the highest level of environmental protection.
The UK has over 416,175 kms of water mains supplying potable water every day to 66.4 million people. Chlorine has been proven to be the simplest and most effective means of disinfecting water in such a large scale, being used within the UK for approximately 100 years.
From water main installation and tanker usage, to the maintenance of service reservoirs and the extensive network of pipes, chlorine has many different uses across the industry.
Water companies, along with the Environment Agency, are always looking for ways to preserve and protect the environment where they possibly can; ensuring that water quality is of the highest standard possible. Chlorine limits are put in place to protect the environment and ensure that water entering watercourses is kept to a high standard.
With the help of innovative pioneers like ATi, Anglian Water has taken a step forward in improving the efficiency and effectiveness of the de-chlorination process, working to reduce the likelihood of residual chlorine that may enter water courses during emergency works or weather events.
Taking an Innovative Step to De-chlorination
With liquid solutions being the most accurate way to dechlorinate, Anglian Water have begun to utilise the latest in flow proportional dosing equipment and chlorine analysis, while also monitoring post-dosage discharges, to improve their de-chlorination process and reduce the likelihood of environmental impact.
Working with Aquadose, who possess years of experience in water treatment systems and analytical equipment, a need to improve dosing control technology was identified, aiming to provide Anglian with a more consistent and accurate dechlorination process.
The exciting, innovative technology allows Anglian Water to capture vital data from its dosing equipment and chlorine analysers, recording a log of dosing parameters, trends and locations, which can then be stored remotely into the cloud.
The secure data capture from the fully calibrated dosing equipment helps to provide Anglian with further validation of the entire dosing process, ensuring that historic data can be kept and is readily accessible.
“This technology is already helping us to better monitor what we’re putting into our region’s watercourses. We always strive to ensure that we protect the environment at every opportunity and these advances in dosing equipment can help us do just that,” Malc Holmes, Anglian Water’s Restoration Innovation Manager, said.
Through the continuous monitoring of the final discharge, Anglian can alsorecord dissolved oxygen, pH and turbidity levels at environmentally sensitive areas. This enables discharged water to be comprehensively evaluated and audited, improving Anglian’s processes through continual learning and improvement.
ATi helped to develop technology that allows chlorine analysis to become more portable, providing greater flexibility to Anglian Water and allowing seamless integration with the water network. Utilising the new plug-and-play technology improves the accuracy of monitoring for the presence of chlorine throughout the entire de-chlorination process.
The additional development of a mobile / tablet app also allows operators to control and monitor the equipment remotely, with wireless connectivity between dosing equipment and chlorine analysers, providing additional dosing control for the very first time.
“We’re already seeing the results of this technology, with better awareness and visibility of the dosing process ensuring that we are always performing within our parameters. Through greater control, we are making sure that we’re driving efficiency and effectiveness in the de-chlorination process,” Holmes added.
