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 or डीएएफ प्रणाली.

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 for maximum industrial durability.

1.हमारी स्वचालित पॉलिमर तैयारी इकाई की विशेषताएं | पॉलिमर खुराक इकाई:

• 3-टैंक एकीकरण डिज़ाइन (मिक्सिंग टैंक, एजिंग टैंक, स्टोरेज टैंक) के साथ लगातार काम करना, संचालन और रखरखाव में आसान, कम कुल लागत
• वर्तमान जरूरतों के अनुसार अधिक स्वचालित 2 भंडारण टैंक प्रकार के रूप में बढ़ाया जा सकता है
• विभिन्न आवश्यकताओं को पूरा करने के लिए पाउडर या तरल अवस्था (वैकल्पिक) दोहरी फ़ीड डिज़ाइन के साथ। आनुपातिक आवंटन फ़ंक्शन आवश्यकताओं के अनुसार तरल एकाग्रता तैयार करना संभव बनाता है
• अनुचित मैन्युअल आवंटन के कारण होने वाले ढेर को कम करने के लिए एक समान और मध्यम एकाग्रता के साथ। पाइप या पंप के अवरुद्ध होने, अनावश्यक रखरखाव लागत और पाउडर खर्च से अच्छी तरह बचा जा सकता है
• विरोधी संक्षेपण, हीटिंग और इन्सुलेशन फ़ंक्शन के साथ पाउडर फीडिंग हॉपर ढेर या गिरावट से बच सकता है
• जब पाउडर फीडिंग हॉपर न्यूनतम स्टॉक तक पहुँच जाता है, तो एलईडी लाइट चेतावनी और स्वचालित स्टॉप फ़ंक्शन समग्र गतिशीलता को और अधिक परिपूर्ण बना देता है

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.
