Foam Today, Gone Tomorrow

When a problem occurs in a wastewater line we usually recommend to start at the discharge and work backwards through the line. This same logic also applies when you have a foaming issue, you must know the source of the problem before you can fix it.

What causes foam?


Foam can grow so much that it escapes the tank.

The experience from our “Industrial Wastewater house calls”, confirmed these as the top 3 causes of foam:

  1. Production dumps instead of a bleed & feed.
  2. Growth of bacteria from colloidal solids – this can also cause odor issues.
  3. Air-line bringing air into the system.

Why is foam an issue?

If foam is not monitored and kept at bay it can cause some of these issues:

  • Create inaccurate level indicators in tanks, which then creates false calls for water or chemistry.
  • The foam can grow so much that it escapes the tank- overflowing on the floor causing unsafe, slippery conditions.

And now for some good foam news:

It doesn’t have to get out-of-control. When metered into the system, AquaPure Defoamer can control the foam before it turns into an issue. Our AquaPure Product Manager, Robin Tiede, has outlined the top 4 factors you should consider when choosing a defoamer:

  1. Defoamer chemistry
  2. Persistence
  3. Knock- down in mils
  4. Dispersion time in seconds
