Question

For Environmental Engineering:

1. (i) List at least five water quality characteristics

2. (ii) Compare surface water and groundwater in terms of their typical water quality

   characteristics

3. (iii) Draw annotated diagrams for a typical surface water treatment plant and a typical

   groundwater treatment plant.

Answer 1

solution is posted below. hoping for a positive response.

1: various water quality characteristics:

they are of 4 kinds namely physical, chemical,microbiological and biological characteristics.

1:physical characteristics: temperature , color , taste and odor, turbidity

2:chemical characteristics: inorganic minerals,carbonate equilibrium,pH and alkalinity, acidity, bilogical oxygen demand and chemical oxygen demand

3:microbiological characteristics: presence of bacteria ,mpn test

2: parameter groundwater surface water

  contamination safe from contamination from animals prone to animal contamination

bacteria free from pathogens not always free

mineral content high mineral content low mineral content

distribution economical costlier than groundwater

treatment less treatment required more treatment required

usage from location can be used in vicinity used for farther away from source

temperature generally constant temperature varies throughout the day
