Tubular Micro Filtration (TMF) • Microfiltration (MF) is a low pressure (0. 7 – Tubular Micro Filtration (TMF) • Microfiltration (MF) is a low pressure (0. 7 – 7 bar, 10 -100 psig) separation process for separation of solids from aqueous solutions by means of a membrane. • This “crossflow” process is carried out by having a process solution flow along a membrane surface under pressure. • Retained particulate matter leaves with the flowing process stream and does not accumulate on the membrane surface What is TMF

Why the Porex TMF Membrane is Better • Unique abrasion resistant topography • PVDF Why the Porex TMF Membrane is Better • Unique abrasion resistant topography • PVDF membrane with PE or PVDF sintered substrate • Membrane is in the pores of the substrate • Anchored into substrate by full depth entanglement • Also chemically bonded in the PVDF/PVDF option

Porex TMF Features Benefits Superior Filtrate Quality – MF/UF barrier filtration - < 1. Porex TMF Features Benefits Superior Filtrate Quality – MF/UF barrier filtration - < 1. 0 ppm SS and 0. 1 ppm metals are typical Can meet strict discharge regulations or feed directly to RO without additional treatment (reuse/recycle wastewater) Can feed directly to RO without additional treatment Reduces overall system capital cost and space requirements No need for Polymer addition Saves money and time. Reduces overall sludge volume Operates at broad temperature range No system upsets with temperature variations – saves operator time and reduces system downtime Can easily handle 2 -5% solids Produces less slurry and better filter press performance Most durable membranes on the market Best investment – holds up to abrasives, strong chemical cleaning, backpulse
