Phytic Acid Membrane Separation Equipment

Phytic Acid Membrane Separation Equipment – Innovator in High-Purity Extraction and Green Processes

Phytic acid, a natural organic phosphorus compound widely found in grains, legumes, and other plant seeds, is extensively used in food additives, pharmaceutical raw materials, daily chemical products, and environmentally friendly corrosion inhibitors due to its excellent antioxidant properties, metal chelation capabilities, and bioactivity. However, traditional extraction methods (such as acid leaching and ion exchange) often suffer from inefficiency, low purity, high energy consumption, and difficult wastewater treatment, severely hindering cost reduction, efficiency improvement, and sustainable development for enterprises. As a leader in membrane separation technology, we offer a comprehensive solution for phytic acid membrane separation equipment, utilizing ceramic membranes, nanofiltration membranes, reverse osmosis membranes, and more as core components to help enterprises achieve high-purity extraction, low-energy production, and clean operations, securing a competitive technological edge in the market.

I. Challenges in Phytic Acid Extraction: Bottlenecks and Limitations of Traditional Processes
1. Low Purity: Acid leaching often introduces impurities such as inorganic salts and proteins, and subsequent ion exchange resins may leave residues, affecting product purity (typically only 70-85%);
2. High Energy Consumption: Multi-stage evaporation and concentration consume significant energy, and high temperatures can cause partial decomposition of phytic acid;
3. Environmental Pressure: Acid leaching wastewater contains high concentrations of phosphorus, acids, and heavy metals, resulting in high treatment costs;
4. Low Yield: Multiple process steps lead to phytic acid loss rates as high as 15%-20%.

How to achieve high-purity (≥95%), low-energy, and zero-pollution phytic acid production? Membrane separation technology provides the perfect answer.

II. Membrane Technology Empowers Phytic Acid Production: Four-Stage Process for Precise Purification
Our phytic acid membrane separation equipment employs a four-stage process chain: "pretreatment + fine separation + efficient concentration + resource recovery," leveraging the advantages of ceramic membranes, ultrafiltration membranes, nanofiltration membranes, and reverse osmosis membranes to comprehensively enhance phytic acid quality and production efficiency.

1. Pretreatment Stage: Rapid Impurity Removal to Reduce Subsequent Load
- Ceramic Membrane Equipment: Resistant to strong acids and high temperatures, perfectly suited for phytic acid extraction solutions (pH 1-3), efficiently retaining suspended particles, colloids, and macromolecular impurities, replacing traditional plate-and-frame filtration and reducing the need for chemical additives;
- Tubular Membrane Equipment: Ideal for high-solid-content feed liquids, with strong anti-fouling properties and stable flux, reducing cleaning frequency.

2. Fine Separation Stage: Targeted Retention, Purity Exceeding 95%
- Ultrafiltration Membrane (UF): Retains molecules with a molecular weight of 1kDa-10kDa, removing residual proteins, polysaccharides, and pigments while preserving small phytic acid molecules;
- Nanofiltration Membrane (NF): Selectively separates monovalent salts (e.g., Na⁺, Cl⁻) from phytic acid, with a desalination rate >90%, addressing the issue of salt residue in traditional processes.

3. Efficient Concentration Stage: Low-Temperature Operation for Energy Savings
- Reverse Osmosis Membrane (RO): Concentrates phytic acid solutions to a solid content of 15%-20% at room temperature, saving over 60% energy compared to traditional evaporation processes and avoiding thermal decomposition of phytic acid;
- Hollow Fiber Membrane: Designed for high-viscosity concentrates with cross-flow configuration, strong anti-fouling properties, and flux decay rate <5%.

4. Resource Recovery Stage: Wastewater Reuse for Cost Reduction and Efficiency Improvement
- The membrane system can recover residual phytic acid and water resources from acid leaching wastewater, achieving a wastewater reuse rate >80%, significantly reducing environmental treatment costs.

III. Technical Advantages: Data-Driven Competitiveness
✅ Improved Purity: Phytic acid purity increases from 80% in traditional processes to ≥95%, meeting pharmaceutical and food-grade standards;
✅ Higher Yield: Closed-loop operation ensures a comprehensive phytic acid recovery rate >98%;
✅ Reduced Energy Consumption: Energy use in the concentration stage decreases by 60%, saving approximately ¥1,200 per ton of product;
✅ Environmental Compliance: Wastewater discharge reduced by 80%, phosphorus content <10ppm, easily passing environmental assessments;
✅ Automated Control: PLC intelligent system monitors pressure, flow, and pH in real-time, ensuring process stability.
