The Science of the 3-Chamber Design

Unlike simple mixing tanks, our unit utilizes three distinct chambers to respect the “aging time” required by high-molecular polymers:

1. Mixing Chamber: Dry powder is wetted by a high-shear vortex mixer. This prevents clumping at the very first contact with water.

2. Maturing (Aging) Chamber: The solution is gently stirred by a low-speed agitator. This allows the polymer chains to fully uncoil (mature) without being sheared or damaged.

3. Storage Chamber: The fully matured solution is held here, ready for the dosing pump to deliver it to your Multi-disc Screw Press 또는 DAF 시스템.

Key Technical Advantages

• Significant Chemical Savings: By eliminating undissolved polymer, our units can reduce your annual chemical consumption by 20% to 30%.

• Precision Dry Feeding: Features a variable-speed screw feeder with an anti-condensation heating device to ensure powder flows smoothly even in humid environments.

• Full Automation (Siemens PLC): The system automatically manages water intake, powder feeding, and solution discharge. It includes low-level and no-water protection for safe, 24/7 operation.

• Material Excellence: Available in high-strength Polypropylene (PP) for cost-effectiveness or Stainless Steel 304/316 최대의 산업적 내구성을 위해.

Frequently Asked Questions (FAQs)

• Q: How does your system prevent polymer from caking and clogging?
  A: Our patented vortex induction wetting system ensures instant, complete powder dispersion upon contact with water, while the programmed maturation agitation keeps the solution homogeneous. This dual action virtually eliminates caking, a common flaw in simple mixer tanks.

• Q: Can it handle different types of polymers (cationic, anionic)?
  A: Yes. The system is constructed from corrosion-resistant materials (SS316, CPVC) and features programmable recipes. You can save settings for different polymers and switch between them with one-touch, ensuring optimal preparation for each.

• Q: What is the advantage over a simple “make-down” tank with a mixer?
  A: The key advantage is guaranteed solution quality and consistency. Manual or basic mixer methods often create weak “fish-eyes” or over-shear the polymer, degrading its effectiveness by 30-50%. Our controlled process preserves the full molecular weight and activity of the polymer, meaning you use less chemical to achieve better dewatering results.

Integrated 3-Chamber Design for Optimal Polymer Maturation

Polymer (PAM) requires a specific aging time to reach its full flocculation potential. Our unit respects this process through a continuous three-tank flow logic:

• Chamber 1: Mixing & Wetting – Dry powder is precisely fed into a high-shear vortex mixer. This ensures every granule is wetted instantly, preventing “fish-eyes” and clumping.

• Chamber 2: Aging & Maturation – The solution is gently stirred by a low-speed stainless steel agitator. This allows the polymer chains to fully uncoil without being broken by high speeds.

• Chamber 3: Storage & Discharge – The fully matured solution is transferred here. It provides a stable supply to your [Multi-Disc Screw Press] or [DAF System] without interrupting the preparation cycle.

Success Case: 22% Chemical Saving for a Paper Mill

The Challenge: A paper mill in Southeast Asia was manually mixing PAM powder, leading to inconsistent sludge dewatering and high chemical waste due to “fish-eyes” in the solution.
Our Solution: Kopay International installed a KPL-2000 Automatic 3-Chamber Unit.
The Results:

• ROI Achieved: The mill saved 22% on annual polymer costs, allowing the equipment to pay for itself in just 9 months.

• Improved Dewatering: The consistent solution concentration resulted in a 5% drier sludge cake from their screw press.

• Labor Reduction: The plant shifted from manual mixing to a fully automated process, freeing up 1 operator per shift.
