Iron removal filtration

    Excess iron in water has a big impact on our body. It can cause digestive system disorders, promote tooth decay and cause skin irritation. Under the influence of solutions and atmospheric factors, iron corrodes. This phenomenon consists in oxidation to Fe2 + and Fe3 + ions, which then precipitate as rust-forming hydroxides. Water […]

Soft filtration

  Water hardness is the sum of magnesium and calcium ions that occur in all possible combinations. Table 1 presents the main distribution of water hardness.   General hardness by cations General hardness by anions   carbonate hardness non-carbonate hardness calcium hardness Ca(HCO3)2, Ca(OH)2, CaCO3 CaSO4, CaCl2, Ca(NO3)2 magnesium hardness Mg(HCO3)2, Mg(OH)2, MgCO3 MgSO4, MgCl2, […]

Activated carbon bed filtration

    The main task of activated carbon in water purification is the removal of chlorine, its derivatives, organic compounds and substances that are responsible for the bad taste, color and smell of water. [1] The large surface and high porosity of activated carbons, as well as the material retained on it, create a favorable […]

Mechanical filtration

The oldest method, which is the first, necessary element of water treatment. This filtration is to remove all suspensions and solids from water. This process protects other devices that treat water and installations against silting and mechanical damage. Pre-filtration prepares tap water for the softening process, iron removal, reverse osmosis or UV lamps. Pre-treatment has […]

Membrane techniques

  Membrane processes are techniques that allow for the separation of impurities with particle and particle dimensions at the molecular or ionic level. These are processes new, and their rapid development has been observed in recent years. Progress in research, in the development of membrane techniques make their application in environmental protection real technically and […]
