Organic Membrane Separation Pilot Unit – Technical Specifications & Configuration Standards

I. Basic Information

1. Equipment Name: Organic Membrane Separation Pilot Unit

2. Model: QS-NF-1812G

3. Technical Specifications

III. Technical Specifications

• Minimum operating volume: 0.8 L

• Filtration area: 0.4 m²

• Feed tank: 5 L with jacketed design for hot or cold water circulation

• Operating pressure: 0–6.0 MPa

• Allowable operating temperature: 5–55°C

• Motor power: 2.2 kW

• pH range: 2–12

• Filtration rate: 0.5–10 L/h (depending on feed material and membrane element)

• Membrane elements: Imported membrane sheets compliant with U.S. FDA, USDA, and 3-A sanitary standards. The pump flow rate is configured strictly according to the crossflow velocity requirements for sanitary-grade membrane elements, ensuring that experimental parameters obtained with this unit can be directly scaled up to industrial production.

• The membrane housing is designed based on fluid dynamics principles to ensure adequate crossflow velocity across the membrane surface, guaranteeing stable and reliable test data. The unit is equipped with a variable frequency drive system, allowing stepless adjustment of the recirculation flow rate to accommodate various experimental conditions and membrane surface flow requirements.

• Interchangeable with other membrane elements including microfiltration (MF), ultrafiltration (UF), nanofiltration (NF), and reverse osmosis (RO) membranes.

• All stainless steel welding is performed using automatic argon-shielded welding with single-sided welding and double-sided formation. The piping in contact with the feed material contains no welded joints, ensuring excellent pressure resistance and corrosion resistance. Both internal and external surfaces of the piping are of high quality. The equipment features simple operation, clean sanitary design, and is safe and reliable.

• Equipment dimensions: 800 mm (L) × 500 mm (W) × 650 mm (H)
