Case Study
Overview
The property is a 156 bedroom hotel located in an area with particularly hard water. It has historically experienced significant hard water problems throughout the hot and cold systems and other critical water related equipment. A trial of the lntegro™ water restructuring technology was agreed and ran from April to October 2021. The trial was overseen by the regional Director of Engineering, with day-to-day management and reporting carried out by the hotel’s maintenance managers.
Following successful completion of the trial, the hotel chose to keep using the technology (instead of water softeners) as their solution for the hard water problems throughout the entire site.
Key Issues
Problems identified at the point of the initial inspection were: the master boiler was not working due to being scaled up to the point that water could no longer flow , without proper flushing the build-up of limescale and the resulting biofilm could lead to higher levels of waterborne bacteria, including Legionella. Control of this was understandably a high priority , showerheads, taps and other water fittings were regularly becoming blocked with scale , the heat exchangers/calorifiers were badly scaled up.
Our Solution
Following a site survey it was decided we would install four lntegro™ units to points in the hot and cold water systems in the hotel in order to remove the existing scale build-up and prevent any more in the future. Two units were installed on the cold water supply, taking care of the entire building. An additional two units were installed directly before the boilers and heat exchangers.
Environmental Benefits
As well as significant cost savings and the other benefits detailed above (improved Legionella control, equipment easier to clean, etc), this hotel will achieve the following environmental benefits:
- Extended life of water related equipment such as pumps, boilers, heat exchangers and improved efficiency of heating and cooling equipment
- Improved water efficiency
- Reduced failures in equipment due to scale and corrosion, meaning decreased engineer visits and reduction in the demand for spare parts, both of which carry direct and indirect (manufacturing and supply chain) increases to the hotel's carbon footprint
- Reduced detergent and chemical use
Summary & Results
The lntegro™ technology immediately began to remove historical timescale build-up, dissolving it back into solution as fresh water passed through the system. By taking samples where the water enters the building (before restructuring), and then at subsequent points further down the line (after restructuring), we were able to show that the technology was working. The level of hardness increased at each sample point as the lntegro™ units dissolved the old scale build-up back into solution. This water analysis was carried out regularly until these readings levelled out, indicating that the system was now clear. This took approx. 45-60 days.
This trial was deemed to be extremely successful by all involved and demonstrated conclusively that the lntegro™system works to remove existing timescale and prevent future formation throughout the hot & cold water systems, critical equipment and appliances. As well as offering a significant return on investment, the hotel is experiencing additional benefits such as improved guest experience and having a more positive impact on the environment.
What the customer had to say?
“We installed the lntegro system in April 2021, a very quick install with no disruption to the hotel operation. Within a month we noticed the reduction in scale in the Rack Dishwasher and Ice Machines. The quarterly cleaning of the showerheads and taps as part of the Legionella prevention programme has been noticeably easier. We have seen an improvement in hot water temperature and pressure indicating the removal of scale build up in the boilers and heat exchangers. Sidon Water have been easy to work with every step of the way resulting in an extremely successful project”
