Hypolimnetic aeration

This process promotes the development of aerobic conditions in deep water, leading to a significant reduction in phosphate dissolution and an improvement in sediment mineralization.

Scientific studies support the effectiveness of implementing technical ventilation measures to maintain year-round aerobic conditions in the deep water, thereby restoring the natural balance of lakes.

TIBEAN, also known as TWBA, is an acronym for the German term "Tiefenwasserbelüftungsanlage," which translates to "deep water aeration system."

Upon reaching the end of the upstream pipe, the mixture enters the degassing chamber, where residual gases are separated from the oxygenated water.

The system includes the following components: TIBEAN can be constructed using materials such as polyethylene, polypropylene, stainless steel, or an aluminum-manganese alloy.

Unprotected steel pipes are generally not suitable for use at lower pH values as they promote the removal of the zinc layer.

When aerated, the oxidation process results in the formation of ferric iron and manganese, causing red-brown and black precipitates, respectively.

The presence of aerobic conditions promotes the processes of nitrification and subsequent denitrification, contributing to the removal of nitrogen from a system.

[1] The oxidation of reduced substances like hydrogen sulfide and methane, both chemically and microbially, as well as the enhanced degradation of organic matter, can help mitigate sludge formation.

To begin, a morphometric measurement of the water body is conducted to assess the depth profile and determine the technical design requirements.

The precise technical design involves evaluating various parameters such as nutrient concentrations, temperature stratification, pH levels, temporal variations of oxygen concentrations, as well as performing calculations related to flow rates, mass transport quantities, and the distribution of suspended solids in the hypolimnion.
