company news about Jiangsu Lanyao Water Treatment Co., Ltd. Launches High-Efficiency Wastewater Treatment Solution: Polymeric Ferric Sulfate (PFS) Demonstrates Remarkable Efficacy Across Multiple Applications

As environmental regulations tighten globally, demand for industrial wastewater treatment continues to surge. Jiangsu Lanyao Water Treatment Co., Ltd., a leader in water treatment solutions, has introduced its flagship product—Polymeric Ferric Sulfate (PFS)—to address diverse industrial and municipal wastewater challenges. Leveraging its unique chemical mechanisms, PFS excels in heavy metal removal, organic pollutant degradation, and oil-water separation, positioning it as a cost-effective and sustainable choice for the water treatment industry.

I. Core Mechanisms of PFS in Wastewater Treatment

PFS, an inorganic polymeric coagulant, purifies wastewater through three synergistic processes:

1. Charge Neutralization: Fe³⁺ ions released by PFS neutralize negatively charged contaminants, destabilizing colloidal particles and promoting aggregation.
2. Adsorption Bridging: High-molecular-weight iron complexes form "bridges" between suspended particles, creating large flocs for rapid sedimentation.
3. Co-Precipitation & Oxidation: Under optimal pH conditions, PFS reacts with heavy metals to generate insoluble precipitates. Simultaneously, Fe³⁺ catalyzes Fenton-like reactions to break down refractory organic pollutants.

II. Versatile Applications: From Industrial to Municipal Wastewater

1. Heavy Metal-Contaminated Wastewater

In electroplating, mining, and steel industries, PFS achieves over 90% removal rates for copper, zinc, lead, and cadmium ions. For instance, a steel plant reported residual concentrations of copper and zinc below 0.1 mg/L after adopting PFS, alongside significant COD reduction. Key advantages include:

• Broad pH Adaptability: Effective within pH 6.5–9, eliminating the need for frequent pH adjustments.
• Stable Complexation: Multi-nuclear iron complexes ensure secure binding of heavy metals, minimizing secondary pollution risks.

2. High-COD Organic Wastewater Treatment

For textile dyeing, papermaking, and similar sectors, PFS reduces COD by 10%–20% through combined coagulation and oxidation, easing downstream biological treatment loads. A textile mill observed 40% faster floc formation, 30% less sludge generation, and 25% lower operational costs after PFS integration.

3. Oil-Wastewater Emulsion Breaking

In petrochemical and machining industries, PFS disrupts the charge stability of emulsified oil droplets, enabling aggregation into larger particles for efficient separation via flotation or sedimentation. Pre-treatment with demulsifiers (e.g., lime) enhances PFS performance.

4. Municipal Wastewater Enhancement

PFS excels in municipal systems, particularly for low-temperature or high-turbidity scenarios. Iron hydroxide flocs adsorb pathogens and colloidal impurities, reducing membrane fouling risks in advanced filtration systems and improving reclaimed water quality.

III. Technical and Economic Advantages

Jiangsu Lanyao’s PFS offers unparalleled benefits:

• Cost Efficiency: Dosage is 1/3–1/2 of conventional coagulants, with reduced sludge disposal costs.
• Eco-Friendliness: Non-toxic residues ensure safe discharge into sensitive water bodies.
• Ease of Use: Compatible with existing infrastructure, requiring no complex equipment.

IV. Future Innovations

Jiangsu Lanyao is advancing PFS formulations to target emerging contaminants like microplastics and antibiotics. The company also explores integration with renewable energy-driven technologies (e.g., solar-enhanced oxidation) to promote resource recovery and energy-neutral wastewater treatment.
