Auto Polyelectrolyte Preparation & Dosing Package

The Auto Polyelectrolyte Preparation & Dosing Package by Verito is a fully automated, skid-mounted system designed for efficient preparation and precise dosing of polymers used in water and wastewater treatment. Featuring a gravity-fed dual-tank design with the Preparation Tank mounted above the Dosing Tank, it eliminates the need for transfer pumps while ensuring consistent solution quality. Integrated with a PLC-HMI based control system, accurate screw feeder, and high-efficiency agitator, the system ensures reliable operation with minimal human intervention—making it ideal for applications like sludge dewatering, clarifier dosing, and effluent treatment.

This dual-level system features a Preparation Tank mounted above the Dosing Tank, enabling gravity-assisted transfer of the matured solution, ensuring consistent flow without transfer pumps. It supports continuous and batch-type operation, making it adaptable for both small- and large-scale requirements.
