Equivalent, equivalence, replacement, alternative, analog, retrofit, analogue, derivative, substitution: Pentair X-Flow 8 INCH 8.0 MM Compact 27, Compact27, ARTICLE CODE: 7821KPC99R, 7821KPJ99R

General Information

TFTP8-27 is manufactured as an equivalent, replacement, alternative, retrofit, analogue and derivative to Pentair X-Flow Compact 27 tubular membrane module.
Tubular membrane is made of tube-like membrane with porous walls, which has super high anti-fouling properties and are widely used in highly polluted wastewater.

Tubular membranes are pressurized modules, which are designed and manufactured for the filtration in industrial wastewater, landfill leachate and other critical applications. These UF tubular membranes are made of upgraded new generation tubular membrane with extra permeability and service life.
Pentair X-Flow Compact 27 equivalent tubular membrane modules are applied in new systems, as well as directly connected to existing UF systems as replacements, providing high-quality permeate by removing suspended solids and other impurities to protect downstream processes or discharge.
