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
· Potato Chips
· Frozen French Fries
· Frozen Foods
· Dehydrated mashed Potatoes
· Dehydrated dices Potatoes
· Potato Flakes
· Potato Starch
· Potato Flour

8. Drying
Washing raw potatoes thoroughly require 5000 to 8000 liters per ton of water depending dirt and sand.
Peeling discharges most of the organic load to wastewater/effluent
Type of peeling used affect the BOD and COD in effluent.
Abrasion Peeling – 4000 mg/l BOD
Steam Peeling – 6200 mg/l BOD pH Acidic
Lye Peeling – 6500 mg/l BOD ph. Alkaline
