Techniques

Chapter 1: Techniques

Enhancing Solids/Liquid Separation: The Pol-E-Z Approach

Pol-E-Z, a revolutionary technology from Calgon Corporation, leverages the power of emulsion polymers to optimize solids/liquid separation in water treatment. This chapter delves into the specific techniques employed by Pol-E-Z to achieve this crucial objective.

1. Coagulation and Flocculation:

• Coagulation: Pol-E-Z's emulsion polymers neutralize the surface charges of suspended solids in water, causing them to destabilize and clump together. This initial aggregation is known as coagulation.
• Flocculation: The coagulated particles are further bridged by the polymer chains, forming larger, heavier flocs. This process, called flocculation, promotes rapid sedimentation and efficient removal of suspended solids.

2. Enhanced Settling and Filtration:

• Settling: The large flocs generated by Pol-E-Z settle out of the water much faster than individual particles, significantly reducing the time required for sedimentation. This enhances the efficiency of settling tanks, allowing for greater throughput and clearer water production.
• Filtration: Pol-E-Z's ability to form large flocs also enhances the efficiency of filtration processes. The filters become less prone to clogging, resulting in lower pressure drop and extended filter life.

3. Sludge Dewatering and Volume Reduction:

• The compact structure of the Pol-E-Z flocs allows for easier sludge dewatering. The water content in the sludge is reduced significantly, resulting in a smaller volume of sludge that requires disposal.

4. Controlled Dosage and Optimization:

• Pol-E-Z's efficiency allows for precise control of chemical dosage. The optimal dosage can be determined based on the specific water quality and treatment objectives. This optimizes the cost-effectiveness of the process and minimizes the environmental impact.

5. Adaptability and Versatility:

• Pol-E-Z's technology is adaptable to various water treatment scenarios. It can be effectively used in municipal water treatment, industrial wastewater treatment, and process water treatment.

Chapter 2: Models

Unveiling the Science: Pol-E-Z's Emulsion Polymer System

This chapter delves into the models and scientific principles behind Pol-E-Z's emulsion polymer system.

1. Emulsion Polymer Structure:

• Pol-E-Z utilizes emulsion polymers, consisting of tiny polymer particles suspended in water. These particles are typically in the nanometer range, ensuring a large surface area for interaction with suspended solids.

2. Polymer Chain Structure and Functionality:

• The polymer chains in Pol-E-Z are carefully engineered to exhibit specific properties. These properties dictate their performance as coagulants and flocculants, including:
  • Charge Density: Affects the neutralization of surface charges on suspended solids.
  • Molecular Weight: Impacts the bridging effect and the size of the flocs formed.
  • Hydrophobicity: Influences the interaction with suspended solids and the stability of the emulsion.

3. Mechanism of Action:

• Coagulation: Pol-E-Z's emulsion polymers attach to the surfaces of suspended solids, neutralizing their surface charges. This destabilizes the particles, causing them to collide and aggregate.
• Flocculation: The polymer chains bridge between the aggregated particles, forming larger flocs. These flocs are strong enough to settle out of the water efficiently.

4. Optimization and Customization:

• Calgon Corporation offers a range of Pol-E-Z products, each tailored to specific water treatment requirements. The choice of emulsion polymer depends on the characteristics of the water, the type of suspended solids, and the desired treatment outcome.
