PTFE Membranes

SSI Aeration’s patented multi-layer PTFE Membranes reduce fouling, scaling and need for cleaning.

High performance PTFE belongs to a category of synthetic rubbers called Fluoroelastomers that is valued the world over for their exceptionally broad spectrum of resistance to chemicals, solvents, fats, greases, etc., which can damage conventional elastomers and shorten the life of traditional membranes.

Since 2004, SSI’s PTFE membranes have demonstrated an improved fouling resistance and reduced need for cleanings in most cases by a factor of 5 to 10 compared with standard EPDM membranes from the industry’s leading manufacturers.

Industries served:

  • Municipal wastewater plants
  • Oil and gas refineries
  • Meat processing plants
  • Carbonated beverage factories
  • Food production facilities
  • Pulp and paper mills
  • Dairy Plants

SSI PTFE Membrane Features and Benefits:

  • Resistance to fouling and calcium scaling
  • Outstanding chemical resistance
  • Outstanding resistance to fats, oils and greases
  • Outstanding resistance to hydrocarbons, fuels, and solvents


Intelligent Upgrade Options

Patented PTFE membranes prolong efficiency and reduce whole-life costs

SSl’s patented PTFE membrane barrier properties not only reduce plasticizer extraction, shrinking, and membrane hardening but also limit dynamic changes that can result from swell, such as creep. Compared with uncoated products that are more susceptible to increases in DWP due to more aggressive fouling and changes in physical properties and weight, the PTFE coated mem­ brane improves the consistency of DWP (Headloss) values over the product life. This directly impacts long-term power costs and the ability of the system to distribute air uniformly across the tank floor.

SSI Telemetry -the inside story solves maintenance problems
At the click of a mouse, you will know the DWP of your diffuser membranes, airflow rate to those monitored diffusers, and air temperature in the submerged piping system. You can sense vibra­tion, pipe roll over, and water in the grid. Automatic moisture purging and automatic acid dosing systems are available. Through multiple cameras, you can see both inside the grids, and surface bubble patterns. Wet probes are also available for DO and WW temperature.

Tracking all this data on a user-friendly online dashboard facilitates communication between consultant and client, manufacturer and rep. This smart technology lets you locate problem areas and allocate resources more efficiently. SSI Telemetry is your preventive maintenance hub in the heart of the plant
