In last week’s blog post, we gave an overview of the main changes and additions in the new BSRIA BG29 2020 guide compared with the 2012 edition.
In this blog post, we focus purely on one new topic in the guide, enabling us to investigate this area in more depth.
The BSRIA BG29 document was first launched as AG 8/91 Pre-commissioning Cleaning of Water Systems in 1991, almost 30 years ago. Many changes have happened in heating and cooling systems since then as we seek to achieve far greater energy efficiencies, resulting in significant differences in how these systems are now installed and operated. Other changes including an increased emphasis on microbiological control and innovations in cleaning techniques. The new sixth edition of BSRIA BG29 reflects these changes.
Now we know what a virus is – how do we kill them?
Last week, we asked: “What is a virus?”. We commented that it is an agent that can cause disease, but it is not “alive” in the classic meaning of life. This time we are going to look at how we can kill it or more accurately, prevent it causing disease and mayhem. This is not only important for human health, but also in agriculture and farming as plant and animal husbandry pathogens can be extremely damaging.
A biofilm will begin to form when free swimming micro-organisms attach to an appropriate surface and produce extracellular polysaccharides. The development of a biofilm can happen on a wide variety of surfaces including inner pipe surfaces, tooth enamel, or even internal medical devices.
In the world of water treatment, corrosion is a major concern. If not controlled, corrosion can lead to poor energy transfer in heat exchangers, creation of favourable microbiological conditions in cooling towers, and even complete failures in steam boilers. Pipework, heat transfer surfaces and externals are all susceptible to corrosion.
B & V Chemicals/Aquatreat continue to monitor the situation and will follow all guidance provided by the Government and NHS in the event of localised cases of Coronavirus.
At B & V Chemicals we pride ourselves on providing exceptional technical support and customer service. Always believing in going the extra mile for our customers, our team of microbiologists and chemists make regular visits to their customers to ensure the water treatment products we provide are the best possible offering for their requirements.
The Biocidal Products regulation (EU 528/2012) has been in place in Europe for some time now.
