What is Froth Formation?
• This is a phenomenon that takes place on many lakes and streams.
• Foam bubbles are produced when organic matter decomposes.
• These foam-producing molecules have one end that repels water and another that attracts water and they work to reduce the surface tension on the surface of the water.
• These foam bubbles are lighter than water, so they float on the surface as a thin film that gradually accumulates.
• The presence of phosphates and surfactants in untreated sewage from Delhi, Haryana and Uttar Pradesh is a major reason behind frothing.
