Industrial Water Reuse in Manufacturing

Industrial Water Reuse – The Role of Water in Manufacturing Processes

Most industrial and manufacturing processes, whatever the industry sector, tend to use good quality or even purified water in one or more of their stages. Despite it being such a commonly used resource, there are a lot of misconceptions about how we reuse water which could have a major impact on how effective our processes are, both from a cost and environmental perspective. Read on to find out about the most common misconceptions surrounding the use and reuse of water in manufacturing processes, and what we can do about them.

E.coli water testing for hot tubs and swimming pools

What is E.Coli & Why Testing Hot Tubs & Swimming Pool Water is a Good Idea

It’s not just Legionella or Pseudomonas bacteria that you have to worry about lurking in your water. Escherichia Coli or E.coli is another bacteria which just loves living in man-made water systems like hot tubs, spas and swimming pools. It will breed rapidly given the right conditions which is why regular water testing is important. Legionella bacteria does best in stored or stagnant water systems where the temperatures are warmer, but E.coli prefers hotter temperatures that are sustained over longer periods.

Biocides for closed systems

Choosing Biocides for Closed Systems – Closed Circuit Heating & Cooling Systems

Most organisations are keen to take steps to control the growth of micro-organisms which can flourish inside closed circuit water systems, including closed heating and cooling systems. Controlling the growth of bacteria in such closed circuit systems can also help to prevent the build-up of biofilm on the inside of pipe surfaces. It will also help limit the bacterial breakdown of any corrosion inhibitor chemicals that have been added to the water in the system.
