Biological oxygen demand(BOD):
Biological oxygen demand is one of the clinical procedures which is used to determine the amount of dissolved oxygen which is needed by aerobic biological organisms in a body of water to director organic material is present in given water samples and certain temperature for a specific period.
Biological oxygen demand and chemical oxygen demand are different processes.
To assess the quantity of surface water for the biological oxygen demand test and other purposes then it is important to understand the characteristics of dissolved oxygen content in water and wastewater.

This is a common building construction material. Nowadays concrete bricks are taking the place of traditional bricks.
Traditional bricks are used for two types of walls. The testing of brick is the same for its uses in any type of wall.
Following are the site tests to check the good quality of bricks:
- Edges of bricks should be sharp and the surface should be scratch resistant.
- All the bricks are of the same size
- Bricks must have a size of standard brick i.e 19 cm X 9 CM x 9 CM. To check the length breadth and height take randomly 20 bricks and observe its edges.
- A good brick should have a bright and uniform color.
- soundness test on brick: select 2 random bricks and stuck with each other so that the clear and ringing bell sound must be produced. It indicates a good and strong brick.
- Structure and material of bricks: select any randomly break and crack it from the middle then observe the inner portion. It must be free from any type of lumps and materials compacted homogeneously.
- Efflorescence test: Bricks must be free from any types of salts. Take a brick and placed it in water for 24 hours. Take the brick out and dry it in a shade. After some time of drying if any white substance produced on the brick it indicates the amount of salt present inside bricks. This type of bricks must be avoided for construction
