Buyer's Digest
Use this page as a product-first sourcing checkpoint before sending an RFQ. Category: Filtration And Membranes. Confirm application fit, capacity, materials, destination, lead time and compliance requirements before comparing suppliers.
Original product description
The CM NF90-4021 is a TFC nanofiltration membrane element intended for industrial water-treatment duties. The supplied product data lists an active membrane area of 28 ft² (2.6 m²), an Na. Cl rejection range of 80–90%, and a single-element recovery rate of 15%.
Listed feed-water limits include a maximum SDI of 5 and residual chlorine below 0.1 mg/L. The product information also gives an operating-pressure value of 30 psi (0.2 MPa).
Potential uses identified in the supplied information include hardness softening, color removal, advanced treatment of municipal water sourced from surface water or most wells, industrial-water production, drinking-water production, and liquid concentration or separation.
Suitability for any specific process depends on the complete feed-water analysis and system design. The stated test conditions are 70 psi (0.48 MPa), 25°C, pH 8, and 15% single-element recovery. The test-solution information references 2,000 ppm Na. Cl and 2,000 ppm MgSO4.
Buyers should obtain the exact test protocol and a model-specific performance sheet before comparing expected permeate output or rejection performance.
Procurement questions to confirm: Verify the NF90-4021 element dimensions and pressure-vessel fit, because the supplied information does not provide a complete connection or compatibility drawing.
Confirm model-specific permeate flow, maximum feed flow, maximum working pressure, pressure-drop limit, allowable pH range, cleaning procedure, and storage requirements.
Also request the accepted feed-water composition, rejection data for the ions or solutes relevant to the project, manufacturing tolerances, inspection documentation, packaging configuration, and warranty terms.
The listed transport package is a carton measuring 61 × 13 × 13 cm with a gross weight of 1.760 kg, but buyers should confirm whether these figures apply to each individual element and shipment lot.
