HEI Polymixer Advantage
Advanced Polymer Mixing Systems for Wastewater Treatment
The HEI Polymixer System utilizes patented maturation technology to achieve 96% polymer activation. While standard mixing units waste up to 85% of your chemicals, HEI focuses on Molecular Activation, reducing consumption by 20% to 50%.
How the Polymixer System Achieves Maximum Activation
In industrial polymer water treatment, the primary goal is full chemical hydration. The HEI Polymixer is a state-of-the-art polymer mixer engineered to transform concentrated emulsion polymers into a uniformly diluted, high-potency solution.
High-Energy Mixing Chamber Design (G-10,000 sec-1)
The unit features a perforated turbine-style impeller driven by a heavy-duty motor. The chamber is baffled to produce high-energy mixing of G-10,000 sec-1. This intensity ensures:
- Elimination of “fish-eyes” and “strings.”
- Rapid blending of high-viscosity polymers.
- A consistent flow of homogeneous diluted polymer.
- Visible Process: Constructed of transparent Plexiglas for easy operator monitoring.
The Science of Maturation: The Patented Aging Chamber
Most polymer mixing systems fail because they skip the maturation phase. After mixing, the solution enters our patented 15-gallon aging chamber.
- The Reality: Polymer molecules are fragile; they need time (up to 10 minutes) to “uncoil” or hydrate.
The HEI Advantage: We maintain the molecular integrity, allowing polymers to hydrate into long, highly active chains. This produces activity levels far superior to non-aged devices.
AUTHORITY CASE STUDY: Why Mixing is Only 10% of the Solution
In the world of industrial wastewater treatment, there is a common misconception: that high-speed mixing alone is enough to activate chemicals. At HEI, our 40 years of field data prove otherwise. We call this The “Shear vs. Activation” Paradox.
The Paradox: High Energy vs. Molecular Destruction
Many operators believe that increasing mixer speed improves results. However, excessive Shear Stress can “chop” fragile polymer chains, rendering them useless before they even reach the waste stream.
The HEI Polymixer is engineered to provide an ultra-high shear zone (G=10,000 sec
−1 for up to 30 seconds. This intensity is precisely tuned to:
- Mechanically strip the polymer of its oil carrier.
- Uniformly disperse microscopic particles to prevent agglomeration (fish-eyes).
- Prepare molecules for instant hydration without destroying their structural integrity.
The Maturation Factor: Why Aging Saves Thousands
Mixing only prepares the polymer; Molecular Maturation (Aging) completes it. Most competitive units skip this phase, discharging “tightly coiled” molecules that provide only a fraction of their potential activity.
The Problem: Without aging, emulsion polymers only reach about 15% to 60% of full activation.
The HEI Solution: Our patented 15-gallon aging chamber provides up to 10 minutes of maturation time. This allows the microscopic particles to hydrate into long, highly active chains, hitting 96% activation efficiency immediately upon discharge.
Independent Test Results: Performance Comparison
In a recent head-to-head audit, the HEI Polymixer was tested against two standard units without maturation chambers. To ensure total accuracy, the same metering pump and settings were used.
Comparative Performance Metrics
| Performance Metric | Competitor Unit (No Aging) | HEI Polymixer System |
| Conductivity (microSiemens) | 330 (Poor Activation) | 515 (High Activation) |
| Activation Efficiency | 15% (High Chemical Waste) | 96% (Maximum Efficiency) |
| Floc Integrity | Fragile & Small | Large, Stable & Strong |
| Verified Polymer Savings | 0% | 20% – 50% Reduction |
The Activation Efficiency Formula
We use a standard engineering formula to determine the true activity of the polymer discharge:
Activation % =
× 100
- C1: Conductivity of feed water
- CT1: Conductivity at unit discharge
- CT2: Conductivity after 1 hour of aging (Full Potential)
Test Result: While the competition struggled at 15% activity, the HEI system registered 5 times the activity rate, proving that Aging DOES make a difference.
Economic Impact: ROI & Field-Verified Savings
The technical superiority of the Polymixer translates directly into wastewater polymer savings.
Expert Insight: If your plant spends $800/month on polymer, an HEI system can reduce that usage by 50% ($400/month savings). At this rate, the system pays for itself in less than one year.
Actual Field Reports from over 1,000 installations verify that switching to an HEI Polymixer reduces polymer consumption by 20% to 50%. By ensuring near-molecular hydration, we help you achieve superior water clarity with half the chemical footprint.
Polymer Blender Performance vs Wastewater Polymer Savings
The competitor’s unit without an aging chamber provided only 15% of the available activity of the polymer discharge. (Note: Since the competitive models do not have high turbulent mixing chambers, the emulsion polymer particles are not adequately “wetted” and then even after an hour of aging time, the polymer reaches only 60% of full activation.) The HEI unit developed 96% of the available activity, registering conductivity of 515 microSiemens. Since the HEI Polymixer produces an activated polymer having up to 5 times the activity rate of the competitive model, it is readily apparent that for equivalent results, the polymer consumption with an HEI system will be substantially less. If you spend $800 per month on polymer, a 50% reduction of polymer usage would cover the cost of replacing your ineffective system in less than one year.

Industrial Durability & Low Maintenance Design
The HEI Polymixer is engineered to eliminate the common failure points found in standard polymer mixing systems. By removing high-wear parts like belts and side-loaded bearings, we ensure a longer lifecycle and lower overhead costs.
Direct-Drive Technology: The motor is connected to the impeller via a Stainless Steel Direct Shaft Drive, ensuring maximum torque without mechanical slippage.
Rapid Accessibility: Every component of the Polymixer is designed to be readily accessible. Maintenance teams can reach and service any part within minutes, reducing downtime significantly.
Automated Safety: Eliminate inconsistent batches and wasted chemicals. The system automatically blends emulsion polymer with pressurized water. In the event of low water pressure or power loss, the unit shuts off automatically to prevent system damage.
