The Polyblend® DP2000 system is a reliable dry polymer feed system for use in water and wastewater applications. The DP2000 is an integrated equipment package capable of automatically preparing a homogeneous polymer solution.

The DP2000 consists of the DD4 dry polymer disperser, and two stainless steel mix tanks, operating in an alternate sequence.

The DP2000 is specifically designed to provide uniform mixing. Dry polymer and water are initially mixed in the DD4 polymer disperser exposing the solution to a high shear agitation via mechanical mixing. The high shear agitation ensures proper activation of the polymer and 
prevents unwanted agglomerations. After brief exposure, the solution 
exits the high shear mixer and flows into the mix tanks. 
 
The second stage mix is a longer, low shear mix. The rotating impeller in the secondary mix tank is a U.S patented “hollow wing” design and covers over half the width of the tank. The low shear mixing continuously and uniformly moves the solution vertically and horizontally resulting in no agglomerations or broken polymer chains.

When a low level is sensed in one of the mix tanks, a
three-way valve directs flow to the empty tank and
the empty tank discharge valve closes simultaneously to isolate the empty tank from the polymer solution.

The DD4 disperser begins a make down sequence and fills the empty tank. After the tank fill and mixing sequence is complete and the alternate tank reaches low level, the full tank discharge valve is opened and flow is directed to the polymer solution feed pumps. The three-way valve then directs ow to the empty tank, the discharge valve on the empty tank closes and the sequence repeats.

The DP2000 is controlled through an easy-to-use microprocessor-based operator interface. The LCD display enables complete operation of all functions including component status, timers, counters, etc.
