Dosing Systems – Precipitants, Acids, Alkalis
Glossary of ETL Verfahrenstechnik GmbH
A dosing system is a setup designed for the precise delivery of defined quantities of liquids. It ensures that specific substances or volumes are provided at predetermined times in exact amounts or mixing ratios. The applied dosing technology guarantees the correct dosage of the respective medium, which is transported through pipelines to the dosing unit. This unit precisely controls the dosing process and can stop it if necessary.
Precipitant dosing systems in wastewater treatment plants are used to bind dissolved substances in wastewater. By reliably dosing precipitants, such as iron(III) chloride, dissolved phosphates form flocs that settle into the sewage sludge, making their removal easier. These dosing systems are particularly essential for phosphate removal, especially in smaller wastewater treatment plants (<5,000 population equivalents), where clear legal requirements for phosphate reduction may be lacking.
Automated dosing systems are particularly advantageous when dealing with aggressive, toxic, or hazardous substances. They improve the handling of risky materials, reduce risks for operating personnel, and enhance the accuracy and efficiency of the dosing process.
Precipitant dosing systems thus play a crucial role in improving water quality, even in smaller wastewater treatment plants, where strict limits for dissolved contaminants, such as phosphate, are often required.
One of the most critical aspects of our DOSY-S acid dosing systems is safety. Their design prioritizes minimizing contact with the reagent, both during filling and dosing. All components are reagent-resistant, and the systems comply with the strictest safety standards.
As a result, our DOSY-S acid dosing systems are vital tools for increasing wastewater treatment plant efficiency while providing reliable and operationally secure dosing solutions.
Summary
In smaller wastewater treatment plants (<5,000 population equivalents), local regulations for monitoring treated wastewater effluent are often less strict than in larger treatment facilities (>10,000 population equivalents).
To provide both environmentally friendly and economically viable solutions for municipalities, ETL Verfahrenstechnik GmbH focuses not on studies but on tangible actions and products that deliver immediate environmental benefits.
Our future focus lies in versatile dosing systems, particularly for reducing phosphate levels in wastewater. Through the planned further development of our proven DOSY-S acid dosing system, we aim to significantly lower phosphate levels with our upcoming DOSY-F precipitant dosing system.
At ETL Verfahrenstechnik GmbH, we believe in action rather than words, in products rather than studies. We have committed to actively improving water quality by offering effective solutions for a more sustainable environment.
