    Introduction To Environmental Engineering

    Uploaded by

    Sheena Ann Stonehill
    Environmental engineering applies scientific principles to improve the environment through providing healthy resources like air, water, and land. It involves controlling pollution and managing waste, water, and public health issues. Historically, ancient civilizations developed early sewer and water systems while more recent work has focused on understanding and mitigating impacts of industrialization and pollution on the environment and human health. Environmental engineering encompasses many areas including water treatment, air quality control, waste management, and site remediation.

    Introduction to

    Environmental Engineering
    ENVIRONMENTAL ENGINEERING
     is the application of science and engineering
    principles to improve the environment (air,
    water, and/or land resources), to provide
    healthy water, air, and land for human
    habitation and for other organisms, and to
    remediate polluted sites.
     involves water and air pollution control,
    recycling, waste disposal, and public health
    issues as well as a knowledge of
    environmental engineering law
    HISTORY OF ENVIRONMENTAL
    ENGINEERING
     The ancient Harappan civilization utilized
    early sewers in some cities
     Romans constructed aqueducts to prevent
    drought and to create a clean, healthful
    water supply for the metropolis of Rome
     15th century - Bavaria created laws
    restricting the development and
    degradation of alpine country that
    constituted the region's water supply
     Mid 19th century (London) - Joseph
    Bazalgette designed the first major
    sewerage system that reduced the
    incidence of waterborne diseases such
    as cholera.
     In many cases, as societies grew, actions
    that were intended to achieve benefits for
    those societies had longer-term impacts
    which reduced other environmental
    qualities.
    SILENT SPRING
     Book authored by Rachel Carson,
    published in September 1962
     The book documented detrimental effects
    of pesticides on the environment,
    particularly on birds. Carson said that
    DDT had been found to cause thinner
    egg shells and result in reproductive
    problems and death. She also accused
    the chemical industry of spreading
    disinformation, and public officials of
    accepting industry claims uncritically
    SCOPE OF
    ENVIRONMENTAL ENGINEERING
     Agricultural engineering
     Biology
     Chemical Engineering
     Chemistry
     Civil engineering
     Ecology
     Geography
     Geology
     Mechanical engineering
     Public health
    FIELDS OF ENVIRONMENTAL
    ENGINEERING
     Environmental Impact Assessment
    The process of predicting the likely
    environmental consequences of implementing a
    project & designing appropriate preventive
    mitigating & enhancement measures as an input
    to decision making.
    Was established to maintain a rational &
    orderly balance between socio-economic
    growth & environmental protection.
     Water Supply and Transport
     Evaluate the water balance within a water
    shed and determine the available water
    supply
     The water needed for various needs in that
    watershed
     The seasonal cycles of water movement
    through the water shed
     Develop a systems to store, treat, convey
    water for various uses
     Water is treated to achieve water quality
    objectives for the end uses
     Wastewater Conveyance and Treatment
    develop collection and treatment
    systems to carry this waste material away
    from where people live and produce the
    waste and discharge it into the
    environment

     Methods of Wastewater Treatment


     Physical

     Chemical

     Biological
     Air Quality Management
    application scientific and engineering
    principles to the design of manufacturing and
    combustion processes to reduce air pollutant
    emissions to acceptable levels
    Scrubbers, electrostatic precipitators,
    catalytic converters, and various other
    processes are utilized to remove particulate
    matter, nitrogen oxides, sulfur oxides, volatile
    organic compounds (VOC), reactive organic
    gases (ROG) and other air pollutants from flue
    gases and other sources prior to allowing their
    emission to the atmosphere
    OTHER APPLICATION
     Environmental Policy and Regulation
    Development
     Contaminated Lang Management and Site
    Remediation
     Environmental Healthy and Safety
     Hazardous Waste Management
     Natural Resource Management
     Noise Pollution
     Risk Assessment
     Solid Waste Management
