Aerating & stripping

During aeration/degassing, substances dissolved in water are brought into contact with the gas phase (air). As a result of concentration differences, substances are introduced into the water (such as the introduction of oxygen) or transferred from the water to the gas phase (such as methane removal).

Aeration / Degassing

Available for: Sales Rental Service

During aeration, air is added from water. The addition to air is applied using differing methods and for different purposes. Oxygen (air) is added to water for the purpose of:

  1. Oxidation: in a number of cases the oxidation of dissolved substances is necessary in order to purify water. This includes the oxidation of dissolved iron during the treatment of groundwater.
  2. Aerobic biological processes that require a higher oxygen content (destruction of organics).

Logisticon is experienced in aerating reservoirs, surface water and groundwater purification. Logisticon also has extensive experience in biological wastewater treatment, of which aeration is a part.

Stripping towers

Stripping towers are used to remove volatile aromatic hydrocarbons (such as benzene, toluene and xylene) or volatile chlorinated hydrocarbons (such as Per and Tri) from water flows.

Logisticon's stripping towers are of the ‘counter-current’ type. This means that the water is pumped to the top of the column of the stripping tower. Air is blown into the bottom of the column. The volatile components move from the water phase to the air phase. When stripping towers are dimensioned properly, efficiency levels of more than 99% can be achieved. Post-treatment of the released air is often necessary. In practice, air-side active carbon filters (GAC) or biological air filters are used to do this.
