Engineered to treat brackish, surface, tap, and borehole water sources, the ELP-8040 delivers a stabilized salt rejection of 99.2% under standard testing conditions (2,000 mg/L NaCl at 25 deg C), effectively removing dissolved solids, silica, heavy metals, and organic contaminants. Constructed with a heavy-duty fiberglass outer casing, precision end caps, and an integrated brine seal, the element withstands maximum operating pressures up to 41 bar and offers wide cleaning versatility across a pH range of 2 to 12 during chemical CIP maintenance cycles.
Technical information
Here are most important things about this product
- Low-Energy High-Flow Production: Generates up to 42.0 m3/day (approx. 1,750 L/h) of purified permeate at a moderate nominal pressure of 10.3 bar, significantly lowering pumping power requirements.
- High Demineralization Rejection: Stabilized salt rejection rate of 99.2% provides superior reduction of dissolved mineral salts, hardness, and conductivity.
- Large Active Surface Area: 37.0 m2 (400 sq ft) active filtration membrane area allows maximum pure water flux within a standard 8-inch diameter format.
- Broad CIP Chemical Tolerance: Supports continuous operation between pH 2 and 11, with short-term chemical clean-in-place resistance from pH 2 to 12.
- Robust Industrial Outer Wrap: Reinforced fiberglass shell provides high mechanical strength, dimensional stability, and resistance against bypass leaks inside 8040 housings.
- Standard Industrial 8040 Geometry: Direct drop-in replacement for any universal 8" x 40" commercial or industrial reverse osmosis pressure vessel.

Please note: Adhere strictly to controlled commissioning procedures to avoid damaging membrane leaves from hydraulic shock or overfeeding. Gradually increase the feed water pressure over 30 to 60 seconds, and allow 15 to 20 seconds to establish normal operating cross-flow velocity. Discard all permeate produced during the first hour of operation to thoroughly purge packaging agents. Elements must remain constantly moist once wetted, and static backpressure on the permeate side must never be permitted. During prolonged outages exceeding 72 hours, preserve the membrane array in an approved chemical preservative solution to inhibit microbial contamination and biofouling.
