A Take on the Serious Problems Caused by Foams

Foam floating on the liquid surface is one of the most noticeable affairs. It’s relatively easy to monitor and easy to handle cosmetic issue. The foam can cause real problems with liquid levels by overflowing, leading to pools of oils around the equipment. These may reduce availability of process equipments and the process speed. When foam enters the system as air is a poor lubricant, it becomes main mechanical problem. So, metal to metal contact can be happening more.

Mechanical Problems
Mechanical problems which can generate foams and air bubbles:
  1. Leaky seals on pumps
  2. High Pressure pumps
  3. Designing Poor System like pump inlet, outlet and tank
  4. Release of pressure
Anxiety is being rising for the mechanical systems due to the following types of foam:
  • Dissolved air:- This acts as part of the fluid phase, except that it can come out of solution as small bubbles
  • Entrained air:- This consists of small bubbles which can be collected on top of any fluid
  • Bubbles:- which are very light to rise on the surface, to be described as foam
Problem Generated by Foam
Bubbles, Entrained and Dissolved air which are present in coolants and processing liquids, can cause various kinds of serious problems, including:
  • Loss of efficiency in work
  • Capacity of pump and storage tanks reduced
  • Bacterial growth
  • Flotation of Dirt / formation of deposit
  • Reduced effectiveness of the fluid solutions
  • Eventual downtime to clean tanks
  • Drainage problems in sieves and filters
  • Problems with formation (i.e. in paper mill it may cause the fibers to form diverse sheets)
  • Cost of replenishing the liquid
  • Cost of entire material rejection due to imperfections
