Corrosion in a water treatment plant. Find out the effects!

One of the main objectives of a water treatment station is the strengthening of water quality,here is also about the functioning of the distribution. Without a preventive behavior, corrosion will occur in the vulnerable segments. This will draw on its own, in addition to maintenance costs, a real danger in for people that are consuming the water.

For example, drinking water providers in the United States reported the failure of pumps and hot water systems. They were also reported and inoperable valves, meters malfunctions and effect on water quality (changes color). Therefore, providers must determine all segments that can be affected by corrosion. This will be a starting point for the elaboration of a strategy to prevent bottlenecks in the system.

Corrosion control

This can be done by applying a corrosion protection system. We mention that selecting the most effective product is a complex process, involving solutions adapted depending on factors that increase the risk of corrosion. Here we can mention three types of elements that may affect installations:

• physical mechanisms: friction, impact and pushing the particles directly on metallic surfaces
   
• Chemical mechanisms: oxidation, temperature changes, various chemical reactions
   
• biological factors: bacterial formations

In developing a plan to prevent the installation of various problems, some measures can be taken by getting answers to following questions:

1) What forces can cause side effects?
2) Where can these effects appear?
3) Whit what materials are we working and what is their condition?
4) What chemicals or organic compounds are involved?
5) What are the consequences of their effects?

Classification of internal corrosion

Electrochemistry                                   -                     Chemical or galvanic

Location                                                  -                   External or internal

Spatial characteristics                           -                     Uniform or pitting corrosion

Influence of microbes                           -                     Microbially-influenced corrosion

Physical cause                                        -                   Erosion corrosion, stress corrosion

These effects can be neutralized by using the right application methods for corrosion protection. It will maintain the water quality, increase durability of equipments and maintenance costs will be significantly reduced. Contact us now and benefit from free consultancy.
