New guide to water system disinfection – Protecting the sectors where clean water matters


The WCS Group has launched a new guide to water-based disinfection control, highlighting the different methods of preventing bacterial proliferation and their pros and cons; ideal for FMs, building services and H&S professionals responsible for safe water used in processes, as part of HVAC systems, process and potable water. Suitable for a range of sectors where clean water matters, the guide covers options for healthcare, food & beverage, leisure and hospitality, manufacturing and more. Protecting your water and water


distribution system, is free to download from safe drinking process water and includes information on both primary and secondary disinfection. Every industry has its own set of challenges


and priorities when it comes to water hygiene and WCS’s guide aims to address each method’s characteristics, comparing commonly used options based on a range of parameters – from the effectiveness of the disinfection, to safety considerations and environmental impact. Chris Abraham, Critical Services


Marketing Director for the WCS Group explained: “Where humans are in contact with water, their safety is of course the main priority, but in applications where a system is closed, for example, this concern can come lower down the list. Protecting your water and water system, acts as a handy reference document, which with the support of water treatment experts will help responsible parties make informed decisions about the


type of disinfection control required for their particular application.”


Disinfection methods covered: • Chlorination (Liquid)


• Electrolytic Chlorine Generation • Chlorine Dioxide Generation • Ozonation


• Ultraviolet Light (UV)


• Ultralox® – a highly effective low concentration form of chlorine


Considerations covered: • Advantages & limitations • Processes • Equipment


• Chemical make-up and quantity • Suitable applications


BSI amends standard for assessing the impact of industrial and commercial sound


Just how much industrial and commercial sound is acceptable and when does it become environmental noise? It’s a subjective area with many variables for assessors to consider, therefore ensuring consistency in the methods used for rating and assessing variable sound levels is fundamental. BSI, the business improvement company,


has just released BS 4142:2014+A1:2019 Methods for rating and assessing industrial and commercial sound. This is an amendment of the 2014 edition of the standard and supports current UK planning guidance and Environmental Agency requirements on noise impact assessments. The standard offers a reference method


for assessors 1 to make decisions on the level of sound, or change of sound, appropriate to each case, including assessing the problem of tones, impulse sounds and the influence of


the context in which the sound is heard. Sources of industrial and commercial


sound likely to be assessed for impact include: • Industrial and manufacturing processes • Fixed installations • The loading and unloading of goods


Mobile plant and vehicles that are an


intrinsic part of the overall sound emanating from the premises David Fatscher, Head of Sector,


Environment, Social and Governance at BSI said: “BSI 4142 is one of the UK’s most widely used standards for the assessment of environmental noise. We listened to feedback from our customers and have improved the clarity to provide those making acoustics and noise assessments with a tighter criterion for assessment. It


can be used to assess sound, or a change of sound, for many reasons such as a response to a complaint or as part of a planning application. Responses to sound can be subjective


and are affected by many factors, from the background sound level, time of day, acoustics environment as well as local attitude to the source of the sound and the characteristics of the neighbourhood. The standard offers support across environmental health, planning and design engineering, legal and training activities where a monitor of industrial and commercial sound levels is required.” BS 4142 was first published in 1967,


revised in 1990, again in 1997, 2014 and now in 2019. It will be fully updated under the systematic review process again in 5 years’ time (2024).
