Write down the names of the ‘facilities’in sequential order for a ‘Conventional Water Treatment Plant’for a ‘Surface Source of Water’. What type of‘impurities’ will be removed by these ‘facilities’?

What are the different types of ‘impurities’ in a ‘Ground Source of Water’? Discuss in detail their ‘effects’ on ‘Public Use and Industrial Use’.                                                                                                                                        

Answer:

Facilities:

                             I.            Filtration

                          II.            Disinfection

                        III.            Storage

                       IV.            Intake Structure

                          V.            Plain Sedimentation

                       VI.            Coagulation Flocculation

                     VII.            Sedimentation

Types of Impurities removed:

1.     Organic matter

2.     Inorganic matter

3.     Heavy metals

4.     Microbial contamination

Types of impurities in Ground source of water:

            Physical impurities:

1)    Turbidity

2)    Electric conductivity

3)    Salinity

4)    TDS ( total dissolve solids)

  Chemical impurities:

1.      Major element contamination

2.    

Effects:

1)    Public Use effect: Public get sick of such impurities. Human illness. Weakens immune system, develops allergy or asthma, reproductive problems and birth defects, effect on mental intellectual and physical developments.

Industrial effect: The water with impurities form corrosion. Industry machines damage.  Reduces life expectancy of machineries, low quality production, more cost of electricity
