BOD Wastewater Removal

Biological Oxygen Demand (BOD) is a chemical procedure for determining the amount of dissolved oxygen needed by aerobic biological organisms in a body of water to break down organic material present in a given water sample at a certain temperature over a specific time period. It is not a precise quantitative test, although it is widely used as an indication of the quality of water.

BOD can be used as a gauge of the effectiveness of wastewater treatment plants. It is listed as a conventional pollutant in the U.S. Clean Water Act.

Two major types of Biological Oxygen Demand are:

  1. Soluble BOD
  2. Insoluble BOD

Soluble Biological Oxygen Demand:

Soluble BOD is often found in dissolved solids such as sugar, and cannot be removed through conventional liquid / solid separation systems.

Insoluble Biological Oxygen Demand:

Chemical and mechanical separation methods work for Insoluble BOD.

ALAR’s technology typically reduces Insoluble BOD by a ratio of 10:1.
