  2. Descaling agent - Wikipedia

    en.wikipedia.org/wiki/Descaling_agent

    Limescale build-up inside a pipe reduces both liquid flow and thermal conduction from the pipe, so will reduce thermal efficiency when used as a heat exchanger.. A descaling agent or chemical descaler is a liquid chemical substance used to remove limescale from metal surfaces in contact with hot water, such as in boilers, water heaters, and kettles.

  3. Electro precipitation - Wikipedia

    en.wikipedia.org/wiki/Electro_precipitation

    Electro precipitation is the removal of heavy metal ions, charged colloids, emulsions and microorganisms by passing direct electric current (introduced via parallel plates constructed of various metals that are selected to optimize the removal process) through contaminated water.

  4. Electrokinetic remediation - Wikipedia

    en.wikipedia.org/wiki/Electrokinetic_remediation

    Electrokinetic remediation, also termed electrokinetics, is a technique of using direct electric current to remove organic, inorganic and heavy metal particles from the soil by electric potential. [ 1 ] [ 2 ] [ 3 ] The use of this technique provides an approach with minimum disturbance to the surface while treating subsurface contaminants .

  5. Water softening - Wikipedia

    en.wikipedia.org/wiki/Water_softening

    Water softening is the removal of calcium, magnesium, and certain other metal cations in hard water. The resulting soft water requires less soap for the same cleaning effort, as soap is not wasted bonding with calcium ions.

  6. Electrocoagulation - Wikipedia

    en.wikipedia.org/wiki/Electrocoagulation

    Electrocoagulation (EC) is a technique used for wastewater treatment, wash water treatment, industrially processed water, and medical treatment. Electrocoagulation has become a rapidly growing area of wastewater treatment due to its ability to remove contaminants that are generally more difficult to remove by filtration or chemical treatment systems, such as emulsified oil, total petroleum ...

  7. Rhizofiltration - Wikipedia

    en.wikipedia.org/wiki/Rhizofiltration

    A system to achieve this can consist of a “feeder layer” of soil suspended above a contaminated stream through which plants grow, extending the bulk of their roots into the water. The feeder layer allows the plants to receive fertilizer without contaminating the stream, while simultaneously removing heavy metals from the water. [4]

  9. Electrical resistance heating - Wikipedia

    en.wikipedia.org/wiki/Electrical_resistance_heating

    Electrical resistance heating is used by the environmental restoration industry for remediation of contaminated soil and groundwater. ERH consists of constructing electrodes in the ground, applying alternating current (AC) electricity to the electrodes and heating the subsurface to temperatures that promote the evaporation of contaminants.
