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 BW8040-400 is an industrial spiral-type reverse-osmosis membrane element listed for brackish-water desalination and high-TDS water filtration. Its effective membrane area is 400 ft² (37.2 m²), with a 31 mil feed spacer.
Published performance data lists a permeate flow of 11,000 GPD (41.6 m³/day), minimum rejection of 99.5%, and stable rejection of 99.6%. These figures are tied to the stated laboratory test conditions: 2,000 ppm Na. Cl feedwater, 225 psi pressure, 25°C, pH 8.0, and 15% recovery.
Actual system output and rejection may differ when feedwater composition or operating conditions differ from this test basis. The listed maximum operating pressure is 600 psi (41 bar), and the stated operating pH range is 2–11. The element is supplied in a carton.
Listed package information is 102 × 30 × 32 cm with a gross weight of 13 kg;a separate specification entry states 1.09 × 0.21 × 0.22 m, so buyers should reconcile these dimensions before ordering.
Procurement questions to confirm: verify the required membrane and pressure-vessel dimensions;confirm whether the proposed feedwater chemistry, TDS, temperature, pH, pretreatment, recovery target, and fouling risk fit this model;request normalized performance tolerances and acceptance criteria;reconcile the two published size records;confirm net element weight, connection configuration, seal arrangement, preservation method, storage limits, packaging, order quantity, customization scope, inspection requirements, production schedule, and applicable replacement terms.
