Wastewater Treatment Under Control – Just One-Step

Struggling with unstable operations and inconsistent water quality?

Maybe your water treatment system is just too complicated.

 

 

In the daily routines of many facility management and environmental protection teams, wastewater treatment often feels like a challenge that starts over every single day. Sudden foaming, turbidity exceeding limits, pH anomalies leading to chemical dosing failures, or filter presses that just won't produce dry sludge—these common on-site issues  aren't always caused by design flaws.More often, they stem from the most basic yet critical aspects: chemical dosing management and operational stability.

Traditional treatment method mostly relies on a dual-agent combination of PAC (polyaluminum chloride) and PAM (polyacrylamide). Although this technique is well-established, fluctuations in water quality or slight operational errors can lead to overall treatment efficiency being unstable, and even result in the discharge water failing to meet the standards.

Now, a new flocculation technology—One-Step Powdery Flocculants—is gradually replacing the traditional process, setting a new standard for wastewater treatment that is simpler, more stable, and more efficient.

 

 

1. What is One-Step Powdery Flocculants? Why can it replace PAC/Pam?

 

One-Step Powdery Flocculants refer to powdered formulations in which all the functional components required for both coagulation and flocculation are pre-integrated into a single package. Including,

• Flocculant
• Coagulant Aid
• Modified Mineral Adsorbents (enhance the removal efficiency of suspended solids)

 

Comparison with Traditional PAC/PAM System:

Item	Traditional PAC + PAM	One-Step Powdery Flocculant
Dosing Steps	Two-stage dosing + pH adjustment	One-step dosing
Operational Complexity	High – requires control of dosage, order, and timing	Low – simply dissolve and stir before dosing
Tolerance to pH Changes	Low – requires precise acid-base control	High – reacts stably within pH 6–9
Stability of Performance	Easily affected by temperature, concentration, and human error	Fast reaction, less influenced by external factors

 

 

 

 

2. Core Product Technologies: Instant Dissolution, High Efficiency, and Multifunctionality Integration

 

The design of One-Step Powdery Flocculants integrates three core technologies: high-solubility polymers, high surface area mineral adsorbents, and reaction-tolerant formulation design.

 

Modified Mineral Base

• Utilizes natural adsorbents such as bentonite and kaolinite as carriers to enhance the aggregation of suspended solids and oils.
• Simultaneously increases the density of formed flocs, aiding in subsequent sludge dewatering and reducing moisture content.

 

Instant-Dissolving High Polymer Flocculants

• Through granulation and dispersion treatment, they can fully dissolve in water within minutes.
• Suitable for both automated dosing systems and manual operation.

 

Built-in Buffering and Coagulation-Aid Components

• Stabilizes the reaction range, reducing sensitivity to pH fluctuations.
• Provides effective adsorption and stabilization for surfactants and demulsification agents in the water.

 

 

 

 

3. Case study: Practical Problems Solved within One-Step

Case 1: Electroplating Plant in Taiwan – Difficult Defoaming & High Sludge Moisture Content

 

• Original Treatment Method: Ferric chloride + PAM + Defoamer
• Problems:​
  • Foam was hard to control
  • Discharge water had unstable suspended solids
  • High sludge moisture content after dewatering
• Improvement Results:
  • After applying the One-Step Powdery Flocculant, foam visibly disappeared and discharge became clear
  • Sludge moisture content decreased after filter pressing
  • Dosing frequency reduced from twice daily to once daily, lowering manual inspection workload as well

 

Case 2: PCB Manufacturing Industry – Fluctuating Heavy Metal Concentrations

 

• Original Situation: Process wastewater containing copper and nickel is highly sensitive to pH fluctuations, often resulting in non-compliance with discharge standards.
• Improvement After Introducing One-Step Flocculant:
  • Copper and nickel concentrations decreased by approximately 30% on average and achieved stable performance across a pH range of 6.3 to 8.5
  • Reduced the frequency of acid/alkali adjustments, improving dosing stability
  • Enhanced performance of downstream sedimentation tank, with clearer discharge water

5. Applicable Industries and System Scope

 

Industries Suitable for This Product:

• Metal Surface Treatment (electroplating, electrophoretic deposition, surface finishing)
• PCB and Semiconductor Manufacturing
• Textile Dyeing and Washing Plants
• Food Processing, Brewing, and Oil/Fat Treatment
• Chemical Manufacturing and Recycling
• Pretreatment for Wastewater Reclamation and Reuse Systems

 

 

 

Conclusion: Making Wastewater Treatment Simpler and More Efficient

When wastewater treatment is challenged by issues like foaming, turbidity, exceedances, and excessive sludge volume, traditional dosing processes often prove too complex and slow to respond.

The One-step Powdery Flocculant is an all-in-one solution specifically designed to address these operational pain points. It simultaneously performs coagulation, flocculation, demulsification, pH stabilization, and sludge structure improvement, streamlining the process while enhancing treatment performance.
