Hydranautics HYDRAcap60 Plus Membrane https://aquacomponents.sa/product/hydranautics-hydracap60-plus-membrane/ Thu, 13 Mar 2025 12:39:18 +0000 https://aquacomponents.sa/product/hydranautics-hydracap60-plus-membrane/ HYDRAcap is a technology using ultrafiltration PES hollow fibers (0.025 um pore size). The modules are suitable for a wide range of applications including ground water and pretreated surface water for potable water production. The low fouling hydrophilic structure enables to operate at high fluxes for long filtration periods.

Hydranautics has more than fifteen years of experience providing HYDRAcap modules (available with a 0.8mm ID fiber diameter or a 1.2 mm ID fiber diameter for high solids load applications).

The HYDRAcap+ range exhibits 20% higher membrane area than standard HYDRAcap range for the optimized footprint.

Regarding UF permeate quality, a 5 LRV bacteria and 4 LRV virus can be achieved thanks to tight pore size (0.025 µm).

All HYDRAcap models meet these following certifications for potable water applications: NSF61, ACS (France), DWI (UK).
