Marn Raistrick, Water Quality Manager at Was Industries UK, assesses how speciflers and engineers can ensure the highest levels of water quality are delivered where required.


WATER TREATMENT BSEE


WATER QUALITY ISSUES? Tackle them with technology


discussion in many stages of building construction, especially when servicing and maintenance contracts come into play. At this stage, if water quality measures have not been taken, certain applications in certain sectors such as hotels, bars, restaurants and leisure facilities may be experiencing the detrimental effects that water has had on key components as a result of scale, a by-product of water across the UK and one which is exacerbated when water is heated.

If appropriate technologies have not been specified and installed to minimise this risk, engineers can find that repairs are more frequent and costlier, a disappointing result for building and business owners. And, whilst the argument is definitely that such technologies be specified as part of the initial system installation, it is possible that this can be rectified in certain situations at a later date.


Inial responsibilies


The quality of mains supply water in the UK is clearly fit for human consumption, yet there is a clear opportunity to ensure that the very best water is supplied to those that need it through additional specification and an awareness of what is required to facilitate this.


In order to ascertain the type of water in each given geographical area, utility companies across the UK can provide a detailed water report. This is also something that many private companies offer as a service. This will help to determine the impact that water will have on processes and equipment and has the potential to be a cost saving exercise in the long-term operations of the business.


uThe OneFlow scale control system can be used at Pointof Entry or PointofUse, depending on the situaon and the way in which water is used.


Investment in such capital costs, rather than on maintenance programmes and repairs created by poor water quality, is fast becoming a more popular option in varying sectors, ranging from the hospitality and leisure industry through to multi-dwelling housing developments. This is particularly


ater Quality in commercial and domestic buildings


continues to be a topic of much


relevant in those that have heating and hot water supplied through a District Heating Centre or those that are reaping the benefits from renewable heating systems such as Ground Source and Air Source Heat Pumps. Scale is generally more evident in areas that have hard water and is a result of dissolved calcium and magnesium salts. And, when hard water is heated (often past around 50C) or left to stand, the water begins to evaporate and the dissolved minerals start to solidify, causing scale. In a commercial setting, this can have a significant detrimental effect. It is estimated that just a 1.6mm coating of scale can make appliances and components 12% less effective, using more energy and shortening the life span of the part in question or indeed, the entire system.


In addition to this, the taste and performance of the water (i.e. the ability to create a lather and obtain truly clean surfaces free from streaking) may be compromised.


Prevenon is beer than cure


The evidence speaks for itself and, as such, prevention is better than cure. It is surely most appropriate to ensure such measures are taken at specification stage, so that ongoing maintenance is all that is required going forward. It is this element of the water quality process that we are keen to educate and support specifiers, facilities managers and installers on, to prevent costly maintenance programmes and repairs when inadequate quality water causes system and mechanical issues. Pleasingly, measures can be taken to eradicate such issues and by sharing technological and product information, decision makers can begin to weigh up the pros and cons of prevention, rather than repair.


We want to support those that are specifying heating, hot water and other water based systems to mitigate risk and move away from the throw away culture that we seem to have become


guilty of. By outlining initial capex and installation costs of products to improve water quality from the outset of a project, tangible and financial benefits can be enjoyed in the future. Investment in such capital costs, rather than on maintenance programmes and repairs created by poor water quality, is fast becoming a more popular option in many sectors including hospitality, catering and leisure where it has been identified that scale is extremely prevalent due to the ways in which water is utilised.


A trusted soluon


Recognising that moving towards such practices in a more consistent fashion requires trusted solutions, Watts’ OneFlow scale control system can be used at Point-of-Entry (POE) or Point-of- Use (POU), depending on the situation and the way in which water is used in any given process.


OneFlow operates through Template Assisted Crystallization (TAC) technology which is used to transform dissolved hardness minerals into harmless, inactive microscopic crystal particles. This is at the very core of the technology and has been proven to increase operating efficiencies of key and critical components in mechanical processes. With no salt required, no backwash experienced, no scale remaining, a small footprint and no electricity requirement its simple, yet highly effective technology, delivers results. It is a proven technology driven by standards and provides a professional solution for the water industry. This particular technology is supported by a range of media and technologies to deliver the water quality required in a variety of ways, supporting other industries that utilise water in their daily business.


By unlocking the potential associated with preventing scale, system and component performance can undoubtedly be enhanced. Further information about all water quality and treatment can be found at:
