New Dry Polymer Feed System From Siemens Maximizes Polymer Activation

The PolyBlend DP110 Dry Polymer Feed System is the new integrated sequential batch, continuous feed system from Siemens Water Technologies. It replaces the existing DP105 system and uses the same blending technology as its predecessor but at almost half the size. The DP110 system's smaller footprint makes it ideal for replacement and retrofit applications in water and wastewater treatment plants sized up to 38,000 metric tons/day (10 MGD) at a 1 mg/l dosage rate.

The DP110 system's unique mixing technology and innovative design provides consistent and reliable performance while optimizing polymer preparation and activation. In addition, it reduces polymer consumption and saves energy with a lower total current usage. The system's small footprint eliminates the need for multiple tank installations, reducing space requirements.

With the DP110 system, dry polymer and water are first mixed in the vortex created by the rotating tank impeller. The system is engineered to prepare polymer solution concentrations up to 0.3% by weight, with a maximum dry polymer feed rate up to 0.86 kgs/hr (1.9 lbs/hr). The system is controlled through an easy-to-use microprocessor-based touch screen operator interface. The LCD display enables complete operation of all functions including dosage rates, solution concentration, run and flow totalizers and alarm conditions.

The PolyBlend DP110 system can also be supplied with a number of additional options including polymer solution transfer pumps and customized controls.
