Product Description

Product Description:

The production is made with one-piece die to save costs. The ECD series aeration disk uses a new type of ethylene propylene diene rubber membrane (EPDM). When compression molded, each cavity is equipped with a separate thermocouple. This process gives manufacturers complete control over the quality of each diffusion film. SSI also ensures that each membrane's perforations are of uniform depth for even air release. The unique mechanical hole cutting technology greatly increases the number of membrane holes per unit area, ensuring that the perforations of each membrane have a uniform depth to achieve uniform air release, and ensure good opening and closing performance for one million times. The EPDM membrane we use has low plasticizer content to reduce hardening and shrinkage, while avoiding creep to achieve better aeration effects.
QCICK CONNECTTM saddle design is fast and convenient. It only needs to be rotated a quarter turn to instantly connect to the pipe. It has an integral seal to ensure a leak-free connection and reduce labor.

PTFE (polytetrafluoroethylene) E and VITON are synthetic rubbers commonly known as air rubber. They are recognized as a high-performance  material due to their broad resistance to chemicals, solvents, oils, greases, etc. that can damage traditional rubber. However, the disadvantage is that it is expensive. Therefore, SI has developed the application of fluoro rubber coating, which is permanently bonded to the surface of EPDM or other base materials through patented technology. Practice has proved that this is an effective method. SSI's new technology allows the diaphragm to not only maintain the excellent physical properties of traditional rubber materials, but also have the resistance to chemicals, solvents and fats found only in the world's most advanced rubber materials, and you can afford it. Many sewage treatment plants that have experienced diaphragm damage due to calcium deposits and solvent corrosion have proven that SSI's new fluoroelastomer-coated EPDM diaphragms will neither produce scaling nor cause any changes in material properties during use.

Intelligent Upgrade Options Patented PTFE membranes prolong the efficiency and reduce whole-life costs. SSI’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 membrane 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, the airflow rate to that monitored diffuser, and the air temperature in the submerged piping system. You can sense vibration, pipe rollover, 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 temperatures. 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.
