INDUSTRIAL WATER TREATMENT

Water is used for a wide variety of industrial applications including:

  • Heating
    • Comfort heating for buildings
    • Heating or cooking in a manufacturing process
  • Cooling
    • Air conditioning
    • Cooling in a manufacturing process
  • Washing / Cleaning

Water treatment is a general name given to a wide range of equipment and chemicals which are there to prevent problems and increase efficiency.  The main problems found in industrial water systems are scale formation, corrosion and bacterial growth.

SCALE FORMATION – HOW DOES SCALE FORM?

The water coming into your site contains minerals. These minerals form a hard scale deposit when you heat the water – you will have seen this in the bottom of your kettle.

WHAT PROBLEMS DOES SCALE CAUSE?

scale in water pipeScale forms on the inside surfaces of pipes and heat exchangers causing a big reduction in                                                                                                heat transfer efficiency as the scale is thermally insulating. Flow rates are also reduced.

This means higher costs in energy for your industrial water system.

 

 

 

 

 

 

 

HOW DO YOU PREVENT SCALE FORMING?

Preventing scale from forming in the first place is of course the best strategy. You can do this by installing pre-treatment equipment such as water softeners or reverse osmosis systems.

These come in lots of sizes from small domestic units to huge industrial systems,                                                                                                                  but they all work in a simple way. They are very reliable and cost effective.

 

 

 

 

CORROSIONcorroded pipe

Industrial water systems – plant, pipework and heat exchangers are made of steel and other metals. As they are in contact with water it’s not surprising that corrosion is going to happen – steel goes rusty very quickly. Metal surfaces can be protected with coatings and chemistry – adding corrosion inhibitors as well as controlling the pH (acidity) of the water can protect systems for many years.

 

 

BACTERIAL CONTAMINATION

Bacteria are naturally occurring in water systems and will multiply into very high numbers given the right conditions. This can present a heath hazard, particularly Legionnaires Disease, as well as causing slime build up in the system. Reduced flow rates, blockages and corrosion are all common problems. Bacterial levels can be controlled using the right combination of filtration, biocide chemicals and cleaning.

 

WATER TREAMENT

Water treatment for industrial water systems is an investment which will maintain efficiency and prevent expensive problems. Done properly, it will save you far more than it costs in fuel, water, repairs and downtime.
