  2. Zero liquid discharge - Wikipedia

    en.wikipedia.org/wiki/Zero_Liquid_Discharge

    Zero Liquid Discharge (ZLD) is a classification of water treatment processes intended to reduce wastewater efficiently and produce clean water that is suitable for reuse (e.g., irrigation). ZLD systems employ wastewater treatment technologies and desalination to purify and recycle virtually all wastewater received.

  3. Air sparging - Wikipedia

    en.wikipedia.org/wiki/Air_sparging

    Air sparging, also known as in situ air stripping [1] and in situ volatilization is an in situ remediation technique, used for the treatment of saturated soils and groundwater contaminated by volatile organic compounds (VOCs) like petroleum hydrocarbons, [2] a widespread problem for the ground water and soil health.

  5. Discharge (hydrology) - Wikipedia

    en.wikipedia.org/wiki/Discharge_(hydrology)

    Thus the water discharge of a tap (faucet) can be measured with a measuring jug and a stopwatch. Here the discharge might be 1 litre per 15 seconds, equivalent to 67 ml/second or 4 litres/minute. This is an average measure. For measuring the discharge of a river we need a different method and the most common is the 'area-velocity' method.

  6. Water treatment - Wikipedia

    en.wikipedia.org/wiki/Water_treatment

    Dalecarlia Water Treatment Plant, Washington, D.C. Water treatment is any process that improves the quality of water to make it appropriate for a specific end-use. The end use may be drinking, industrial water supply, irrigation, river flow maintenance, water recreation or many other uses, including being safely returned to the environment.

  7. Environmental engineering - Wikipedia

    en.wikipedia.org/wiki/Environmental_engineering

    Environmental engineering is a professional engineering discipline related to environmental science.It encompasses broad scientific topics like chemistry, biology, ecology, geology, hydraulics, hydrology, microbiology, and mathematics to create solutions that will protect and also improve the health of living organisms and improve the quality of the environment.

  8. Dielectric barrier discharge - Wikipedia

    en.wikipedia.org/wiki/Dielectric_barrier_discharge

    The discharge is taking place in normal atmospheric air, at about 30 kHz, with a discharge gap of about 4 mm. The foot of the discharge is the charge accumulation on the barrier surface. Dielectric-barrier discharge (DBD) is the electrical discharge between two electrodes separated by an insulating dielectric barrier. [1]

  9. Thermal pollution - Wikipedia

    en.wikipedia.org/wiki/Thermal_pollution

    Thermal pollution, sometimes called "thermal enrichment", is the degradation of water quality by any process that changes ambient water temperature.Thermal pollution is the rise or drop in the temperature of a natural body of water caused by human influence.
