At SSI Aeration, Inc. we understand that different customers have unique water treatment needs. We engineer our diffuser systems to suit a variety of projects. You can see how we build this philosophy into our systems through the features listed below.

A Complete Product Line Available for Your Aeration System

Create the system that fits your needs. We engineer fine bubble disc diffusers and mount them on a wide range of piping materials, including:

  • PVC
  • CPVC
  • PP
  • Stainless steel

Your choice of connector materials also impacts the final system’s performance. When we attach your diffusers to your pipe, we can use components such as:

  • Saddles
  • Grommets
  • Pre-assembled PODs™

Wondering how to assemble your system? Let us provide a retrievable system or a fixed grid. Our systems can also come in the form of a kit or with most of the parts pre-assembled. We will discuss your needs so we can offer recommendations that fit your situation.

Piping System Integrity

We use double anchors and a thicker wall pipe for fewer breakages. Compared to the average diffuser system, we use 38% thicker piping. Our diffusers’ double rod support stands to provide twice the resistance to thermal and hydraulic loads. This design reduces the risk of failure due to temperature or water velocity. During the design process, we locate where the pipe needs the most support and attach the supports to these areas. By completing these steps, we can increase the product’s longevity.

Comprehensive Design Services and After-Sales Support

SSI Aeration, Inc. engineers can assist with every step of the design process. Let us help with process simulations, hydraulic studies and biological and mixing calculation. We staff a full drafting department who can create 3D drawings and animations to bring your ideas to life. Our specialists can also offer support for specifications and CAD drawings. The service and installation crew at SSI Aeration, Inc. can support you throughout the early stages of your project. Since we operate worldwide, we also have a global, multilingual staff dedicated to your satisfaction.fine bubble disc diffusers

Intelligent Upgrade Options for a Superior Diffuser

Our team understands the importance of efficient wastewater treatment systems. To further increase your system’s performance, we offer innovative upgrades you can add to your purchase. Read more about our upgrade options below.

Patented PTFE Membranes

Patented PTFE membranes from SSI Aeration, Inc. prolong your system’s efficiency and reduce its whole-life costs. Our membranes reduce plasticizer extraction, membrane hardening, and shrinking. Since they protect your diffuser from these issues, they also reduce the risk of dynamic changes such as creep that result from the swell. Coating your membrane in PTFE makes your headloss values more consistent throughout the product’s life. Compared to an uncoated membrane, our PTFE membranes improve long-term power costs and air distribution. PTFE membranes from SSI also resist:

  • Fuels
  • Solvents
  • Hydrocarbons
  • Chemicals
  • Fats, oils and greases

Our PTFE membrane’s resistance to these materials makes it suitable for food processing and oil and gas refineries in addition to wastewater treatment plants.

When you use our PTFE membrane in your aeration system, your system also stays cleaner. Compared to leading EPDM membranes in the industry, they feature a reduced need for cleanings and improved fouling resistance. Our PTFE membrane demonstrates this improvement over its competitors by a factor of five to 10.

SSI Aeration, Inc. Web Portal Telemetry Technology

When you have maintenance problems, you can view the inside story with telemetry. View your system’s qualities in the click of a mouse to understand how to resolve aeration issues. Our telemetry software can track diffuser membrane DWP, airflow rate to the diffusers, and air temperature in the piping system. It detects pipe rollover, vibration, and water in the grid. You can also add automatic acid dosing and moisture purging systems to increase your diffuser’s effectiveness. We have wet probes available for recording DO and WW temperatures.

Your SSI Aeration, Inc. telemetry software can track all of these metrics and more. It features multiple cameras that let you observe surface bubble patterns and the inside of the grids. A user-friendly online dashboard shows you the information you need to take action. SSI telemetrics improve communication among all parties involved, including the customer, consultant, manufacturer and representative. Consider SSI telemetry to be your preventive maintenance hub in the heart of your plant.
