Optimization of wastewater treatment plants through a higher energy efficiency with the DOSY acid dosing system

The energy costs of a wastewater treatment plant are mainly caused by the generation of compressed air for the biological revitalization. Increasing calcification and other contaminations of the aeration elements leads to increased back pressure and thus to a higher energy consumption. In addition, overloading of the blowers or compressors can lead to failures, requiring a reduction in air flow and possibly causing damage to the aeration membranes and basic bodies.

An effective solution to these problems is offered by the DOSY from ETL Verfahrenstechnik GmbH. It inserts acid directly into the aeration line at the intended dosing point, with the air flow transporting the nebulized acid to the aeration elements. There, the acid dissolves the lime, cleans the elements and lowers the operating pressure in the overall system. This ensures smooth aeration and increases the efficiency of the treatment plant.

Studies have shown that regular treatment with acid can also extend the lifecycle of the aerators and significantly reduce energy consumption. There is a direct correlation between the pressure increase in the aeration system and the power consumption of the compressors.

The DOSY (acid dosing system) is designed for use with formic acid and acetic acid, and the high mobility of the barrel-container makes it easy to reach any location on the plant. Installation is done by an existing ½-inch IG-ball-valve on the aerator pipe and a supplied adapter on the dosing line.

By using the standard auxiliary pump, the dosing tank can be safely filled from a storage canister or emptied before storage.
