How do glycols prevent freezing in water treatment?

As outside temperatures drop to below 0oC in the winter months, there is a risk that water recirculating in chilled systems will freeze. In order to prevent the water from freezing, it is often necessary to add an a glycol-based antifreeze. 

B&V launches new range of spa and swimming pool chemicals

In October 2020, B & V Chemicals will be launching a new range of spa and swimming pool chemicals.

5 problems with closed circuit systems and how to solve them

The problems encountered in closed circuit systems are like those in open systems, such as scale and corrosion. However, the fixed volume of a closed system allows for water treatment products to be dosed at much higher levels than is possible in open systems, where water is constantly lost to drain.

Testing the effectiveness of corrosion inhibitors in closed circuit systems

Closed circuit systems are susceptible to corrosion, which can negatively impact the function of the system. The good news is that the low make-up of a closed system allows us to dose water treatment products at much higher levels than in open systems, where water is constantly lost to drains. Corrosion control can therefore be more easily achieved in closed circuit systems.

How inhibitors prevent corrosion and scale in closed circuit systems

Closed circuit inhibitors are often referred to as corrosion inhibitors, but their function is considerably more complex than that. Our closed circuit inhibitors are indeed specifically formulated to inhibit corrosion, but equally important is their ability to prevent the build-up of scale and to stop the deposition of suspended solids (fouling).

How to calculate closed circuit system volumes

In our recent blog posts, we’ve looked at the various chemicals and standards related to closed circuit systems. In this blog post, we take a step back and consider one critical piece of information: how to calculate the correct dose of chemicals to be used in a closed system.

8 things to consider when selecting a biocide for closed circuit systems

A biocide is a chemical treatment formulated to effectively control microbial growth. It is critical to ensure the correct biocidal treatment regime is implemented and regular checks carried out to eliminate the risks associated with microbial growth, such as health hazards, heat transfer losses and under deposit corrosion.

Why pre-commission cleaning of pipework systems is essential

Effective pre-commission cleaning of pipework systems is absolutely critical. Unfortunately, the important nature of this operation is often overlooked or under-valued.

Closed-loop pre-treatment cleaning (CPC) in closed circuit systems

This is the sixth blog in our series on the BG29/2020 Pre-Commission Cleaning of Pipework Systems guidelines. Here we take an in-depth look at the closed-loop pre-treatment cleaning (CPC) procedures for closed circuit systems.

Revisions to microbiological test methods in the new BSRIA BG29 2020

In last week’s blog post, we gave an overview of the potential problems caused by microbiological growth in closed circuit systems. In this week’s blog post, the fifth in the series relating to BSRIA BG29 2020, we examine the main differences in microbiological test methods and specifications in the new standard in relation to the previous 2012 edition.
