Polymer Dosing Systems
Precision Chemical Feed Solutions for Wastewater Treatment
At AllWater Technologies, we supply fully integrated polymer dosing systems to support industrial and municipal wastewater treatment processes. Engineered for accuracy, reliability, and ease of operation, our systems are ideal for applications involving clarification, sludge thickening, or dewatering. Whether dosing liquid polymer or preparing powder polymer solutions, we offer custom-built packages tailored to meet your flow rate, concentration, and process requirements.
With rising environmental standards and growing demand for efficient solids separation, choosing the right polymer dosing equipment is critical to maintaining compliance and minimising operational costs.
What Is Polymer Dosing?
Enhancing Wastewater Treatment Through Flocculation
Polymers are synthetic organic flocculants that bind suspended solids into larger aggregates (flocs), allowing them to be easily separated from water through sedimentation, filtration, or flotation. This process—called flocculation—is essential in many treatment applications, including:
- Primary and secondary clarification
- Sludge dewatering
- Dissolved air flotation (DAF) systems
- Industrial effluent polishing
Polymer dosing systems automate and control the delivery of these flocculants, ensuring consistent chemical performance and effective solids removal. By combining mechanical mixing, ageing, and accurate dosing, our systems maximise treatment efficiency while reducing chemical waste.

Polymer Types and Selection
Selecting the correct polymer type is essential for process efficiency. Polymers are typically available in three forms:
- Cationic Polymers – Attract negatively charged particles (commonly used in sludge dewatering)
- Anionic Polymers – Attract positively charged particles (used in clarification and filtration)
- Non-Ionic Polymers – Neutral charge; used where ionic interference is a concern
The appropriate polymer is chosen based on a range of factors, including:
- Particle charge and size
- Water chemistry (pH, hardness, conductivity)
- Flow rates and residence time
- Process objectives (e.g. sludge thickening vs clarification)
Our team can conduct jar testing and water analysis to help you select the optimal polymer and configure the system for consistent, reliable dosing.
Our Polymer Dosing System Range
We offer a full suite of polymer dosing system configurations for both liquid polymer and powder polymer applications. Systems can be supplied as standalone units or integrated into complete wastewater treatment plants.
