Introduction
A waste treatment facility required a reliable and accurate dosing system for powdered materials as part of its SWTE process. The system was needed to support controlled chemical dosing, ensuring stable treatment performance, operational safety, and consistent process efficiency.
Enge Plas Automation was engaged to design and supply a precise weighing and feeding solution tailored for industrial treatment applications.
Challenges
he existing dosing process faced issues related to inconsistent feeding accuracy and unstable batch control. Variations in powder flow affected dosing precision, leading to inefficiencies in the treatment process.
Manual handling and basic feeding methods also increased the risk of material spillage and reduced overall process control. In addition, achieving consistent batch weight for chemical reaction stability was a key operational requirement.
Solution
Enge Plas Automation supplied a Powder Weighing System consisting of a Micro Batch Screw Feeder, Batch Weighing Hopper, and Rotary Valve.
The Micro Batch Screw Feeder ensured precise and controlled dosing of powdered materials based on required setpoints. The Batch Weighing Hopper provided accurate batch measurement to maintain consistent dosing weight before transfer. A Rotary Valve was integrated to regulate material discharge and maintain stable flow into the system.
The complete solution was designed for accurate, repeatable, and controlled dosing performance within the SWTE process.
Results
Following implementation, the facility achieved improved dosing accuracy and more stable treatment performance. Batch consistency was significantly enhanced, resulting in better process reliability and reduced material variation.
Material handling became more controlled, reducing spillage and improving operational safety. The automated system also improved overall efficiency by minimising manual intervention.
Conclusion
The implementation of the powder weighing and feeding system by Enge Plas Automation successfully improved dosing precision, process stability, and operational control. The integrated micro batch feeding solution provided a reliable and efficient method for controlled material dosing within the SWTE application, supporting consistent treatment performance.
