Dosing Systems / Metering Systems
Glossary of ETL Verfahrenstechnik GmbH
A dosing system refers to a setup designed for the precise delivery of liquids in predefined quantities. The system ensures that the liquid is supplied either proportionally, by volume, or in a combination of both, tailored to specific system requirements or operating conditions.
Dosing systems and metering systems are essential in various industries. They optimize production processes by automating the accurate distribution of substances in different states of matter (such as gases, liquids, suspensions, pastes, powders, granules, etc.) and with different chemical properties.
These systems are responsible for providing specific substances or volumes at the right time and in exact quantities or mixing ratios. The applied dosing technology ensures the correct dosage of the respective medium. The medium is transported via a piping system to the dosing unit, which precisely controls the dosing process and stops it as needed.
Fully automated dosing stations are often the safest choice, particularly when handling aggressive, toxic, or hazardous substances. They simplify the handling of dangerous materials, minimize risks for operators, and enhance the accuracy of the dosing process.
Modern, fully automated dosing systems can operate independently without manual intervention and can be remotely controlled or reconfigured if necessary.
For example, acid dosing systems play a crucial role in wastewater treatment, particularly in sewage treatment plants. They ensure that the aeration elements essential for the purification process remain clean and functional. These elements introduce oxygen into the wastewater, but over time, they become clogged with deposits, reducing energy efficiency.
An acid dosing system significantly improves efficiency and reduces costs, with a strong focus on safety! All components are acid-resistant and meet the highest safety standards.
Depending on the type of liquid being dosed—whether it be precipitants in wastewater treatment plants or alkalis and acids for pH regulation in electroplating facilities—the DOSY-S acid dosing system from ETL Verfahrenstechnik GmbH offers tailored solutions for a wide range of applications.
Summary
A dosing system is used for the precise supply of liquids, such as acids, alkalis, or precipitants, in various processes or facilities.
In the context of wastewater treatment plants, an acid dosing system is responsible for cleaning aeration elements and removing lime deposits. Removing these contaminants reduces system pressure, minimizes energy consumption, and extends the service life of aeration components. The dosing system thus plays a critical role in the efficiency and longevity of aeration systems.
A precipitant dosing system in wastewater treatment plants is designed to bind dissolved substances in wastewater. The precise dosing of precipitants, such as iron(III) chloride, enables dissolved phosphates to be converted into solid phosphates, which can then be easily removed. Given the potential risk of eutrophication due to excessive phosphate accumulation in water bodies, such dosing systems are a crucial component of phosphate removal.
In applications such as electroplating facilities, an alkali dosing system ensures that coating quality is maintained by regulating the pH level. The pH value, which indicates the acidity or alkalinity of a solution, has a significant impact on the final quality of a coating.
