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 PSI MEMBRANE PX120-8040 is an 8-inch, spiral-wound reverse osmosis membrane element designed for high-pressure concentration service.
Its stated maximum operating pressure is 1,740 psi (120 bar), making it relevant to industrial projects that need to reduce liquid volume before downstream thermal treatment or increase water and resource recovery. Published nominal performance is 7,400 gpd (28 m³/day) product flow with 99.70% stable salt rejection.
These values were measured using 32,000 ppm Na. Cl feed water at 800 psi (5.5 MPa), 77°F (25°C), and 8% recovery for a single membrane element.
The stated water-yield variation is ±15%, so buyers should evaluate projected output against their actual feed chemistry, temperature, pressure, recovery target, and system configuration. The element has 350 ft² (32 m²) of effective membrane area and a 34 mil feed spacer.
Listed operating limits include a maximum feed-water temperature of 113°F (45°C), maximum pressure drop of 1 bar, continuous operating pH of 2–11, cleaning pH of 1–13, maximum feed-water SDI15 of 5, maximum influent turbidity of 1 NTU, and residual influent chlorine below 0.1 ppm.
Supported uses include industrial wastewater treatment, minimum-liquid-discharge and zero-liquid-discharge systems, and industrial resource recovery or recycling.
The supplied application information also identifies metals processing, lithium extraction, chemical and petrochemical operations, and water softening as relevant areas. Final suitability must be based on a project-specific membrane-system review rather than the application label alone.
Before procurement, confirm the complete feed-water analysis, target permeate quality, required recovery, concentrate composition, pretreatment design, scaling and fouling risks, cleaning protocol, element quantity, pressure-vessel fit, and allowable pressure drop.
Buyers should also request a current product datasheet and verify dimensional tolerances, seals and connectors, expected service life, storage and preservation requirements, shipment configuration, customization scope, delivery schedule, and the warranty terms applicable to the specific quotation.
