ENVIRONMENTAL SCIENCE AND ENGINEERING (BCE101) Requirment of Human Being :‐ ‐ Energy ‐ Water ‐ Food Quantitative & Qualitative Environment Engineer’s Work –    → To provide good quality of water (Water treatment plant)  → Waste water treatment → Control on Air Pollution to Maintain the Air Quality (Temperature, Pressure, Wind, Moisture) → Control on Water Pollution → Solid Waste Management (Storage, Separation & Transportation) 1‐Book Environment Engineering By Gerard Kiely 2‐H.S. Peavy D.R. Rowe G. Technobanog Lous 3‐ Water Supply Engineering by S.K. Garg 1.1 Ecological Perspective:‐

→  The  environmental  engineer  is  interested  to  use  the  varies  physical  resources  such  as  natural  energy  (waves,  wind,  minerals,  hydroelectric)  and water for domestic & living purpose. →  Therefore,  It  has  to  understand  the  functioning  with  the  living  system  and its interaction with the environment. → Environment – (or Ecosystem) It consists of four major element such as (i) Land (ii) Water (iii) Air and (iv) Living Organism (Plant & Animals) Environment (Ecosystem) Physical Environment (Abiotic) Biological Environment (Biotic) Living Organisms       (Planteanimals, Viruses, Bacteria, Fungi) Hydrosphere                            Lithosphere                           Atmosphere (Water over the earth (Solid earth & soils)      (air upto a distance  & inside the earth) of 700 km.) →  Living  organisms  are  dependent  on  each  other  &  depends  on  the  physical  environment. Ex.  Plans grow on land & in water. Herbivorous animals use the plant as food. Carnivorous animals eat herbivorous animals.

1.2 Value of Environment :‐ or Resources Natural Resources Renewable (Energy from sun, water  and Biological cycles) It is recycled & reused.     Non‐renewable        (Fossil, Fuel, Minerals etc) Forest Plantation They are not Replaced. Amount are finite. Abstract (Animal, plant and natural sight used for tourism) 1.3 Environment Auditing:‐ Listing of all the resources of an area Different types of developmental work go ahead in an area depends on the  economical consideration. It has to restrict the economy (money) cased. Therefore, We have to audit or make a list of all the resources of the area.  (Environmental auditing) Auditing No’s of species (Living organisms) exist Uses of the living environment. Direct uses Indirect uses

Food, Industrial & Commercial products, tourism, medicines etc. 1.3.1 Direct use Food – Plants or domesticated animal products  Industrial  &  commercial  products:  ‐  Mineral,  fossil,  fuel,  wools,  cotton,  jute, rubber etc. Medicines‐ 1.3.2 Indirect Uses 9 Biodiversity is the biological processes themselves that provide the value. It is regarding about indirect uses of environments. 9 Environment consists of populations of species‐with air, water, land. Population of one species (Environment) Biological     mixed together with other  Process helps     species The entire system.       Communities Many communities are  Combined   Landscape
