2.2. Classification of Water Quality Parameters

Try these first

1. 1.

   Define Total Dissolved Solids (TDS).

   Hint

   What do you think TDS consists of?

2. 2.

   What does Total Suspended Solids (TSS) indicate?

   Hint

   Think about clarity and what might affect it.

3. 3.

   What does TDS stand for?

   • Total Dissolved Solids
   • Total Defined Solids
   • Total Dust Solids

   Hint

   What is the term that involves substances dissolved within the water?

4. 4.

   True or False: BOD measures only the biodegradable portion of organic material.

   • True
   • False

   Hint

   What part does BOD exclusively focus on regarding organic matter?

5. 5.

   A local river shows BOD values consistently above safe limits, while COD values are moderately elevated. Discuss how this scenario impacts aquatic ecosystems and public health.

   Hint

   Reflect on the connection between these values and ecosystem health.

6. 6.

   An industry discharges wastewater with COD levels significantly higher than local standards but has a low BOD. Explain the implications of this discrepancy for water treatment facilities.

   Hint

   Consider what high COD means for sustainability and treatment capability.
