Potato Wastewater Treatment

Rapid growth is the synonym for potato Industry from past two to three decades accompanied by enormous increase in the amount of water & wastewater produced.

As per estimation US’s Potato Industry alone generates about 1,300,000,000 kg of wastes each year.


Source of Wastewater production in Potato processing Industry includes

· Washing

· Peeling

· Additional Operations


Potatoes with high solid content, low reducing sugar content, thin peel and uniform shape & size are preferred for processing.


Potato Contains

  • · 18% Starch

  • · 1% Cellulose

  • · 81% Water which contents contains protein & carbohydrates.


Types of Potato Processing Units
