SWRO membrane joins NanoH2O’s product line

The addition of a new seawater reverse-osmosis (SWRO) membrane to NanoH2O’s high-flux high-rejection QuantumFlux product line was announced at the IDA Congress on 5 September 2011.

The Qfx SW 400 ES features 400 ft² (37 m²) of active membrane area with a permeate flow rate of 13,700 GPD (52 m³/d), which NanoH2O says is more than any other SWRO membrane on the market.

Like its predecessor, the Qfx SW 400 ES features best-in-class salt rejection and was recently awarded NSF Standard 61 Certification, once again attesting to the safety and viability of thin-film nanocomposite membranes when used for the production of potable water.

Also new to the NanoH2O product line will be an innovative anti-telescoping device (ATD) designed for durability and ease of use. By the end of the year, all of NanoH2O’s QuantumFlux 8-in SWRO elements will incorporate this new ATD that features:

  • New rib design for added durability
  • Lip feature for easier membrane removal from the pressure-vessel
  • Convenient bidirectional brine-seal that allows installation and removal of membranes from either end of the pressure vessel
  • Gutter feature under the brine-seal to equalize pressure
  • A new ATD seal-plate design to visually distinguish Qfx membranes
  • “As demonstrated by the Qfx SW 400 ES, NanoH2O is committed to pushing the envelope on technology and performance,” said Nicholas Dyner, vice president of sales and marketing for the company. “The Qfx SW 400 ES is the most productive and energy-efficient SWRO membrane on the market, designed to lower our customers’ capital expenditures and operating expenses while offering ease-of-use features to assist operators in the maintenance and care of their RO system.”
