Foods and Beverages
The food and beverages processing industry requires a huge amount of water. One of the main problems is the amount of waste water continuously produced in the food plants. The water is used as an ingredient, a cleaning agent, for boiling and cooling purposes, for transportation and conditioning of raw materials
The average wastewater flow per ton of product is given in the following table:
| Beer | 9-11.5 |
| Bread | 2-3.5 |
| Meat packing | 13.5-18 |
| Milk products | 9-18 |
| Whiskey | 54.5-73 |
Food processing can be divided into four main fields:
As an example, find below some wastewater issues and Lenntech pretreatments associated to a kind of food processing.
