PTFE test report

SSI PTFE and PEEK coated diffusion films do not contain PFAS or PFOA. 

When SSI worked with suppliers to develop coatings in the 2000s, SSI insisted on coating packages that did not contain heavy metals or by-products that could theoretically be used in potable water service, even if our products were used in wastewater.

Applications

COMPANY STRENGTH

In a wastewater treatment plant, the Coarse Bubble Diffuser is installed in the aeration tank, where it releases a constant stream of small air bubbles. These bubbles rise to the surface, creating turbulence and increasing the contact between air and water. This allows for the transfer of oxygen from the air into the water, promoting the growth of beneficial bacteria that break down organic matter.

COMPANY STRENGTH

In an aquaculture facility, the Coarse Bubble Diffuser is used to provide oxygen to fish and other aquatic animals. The small bubbles created by the diffuser help to increase the dissolved oxygen levels in the water, creating a healthier environment for the aquatic life to thrive in.

D-1

In industrial processes, the Coarse Bubble Diffuser is used to aerate and mix liquids, such as in fermentation tanks or chemical reactors. It helps to improve the efficiency of the process by providing a constant supply of oxygen and promoting mixing and circulation.

COMPANY STRENGTH

Overall, the Coarse Bubble Diffuser is a versatile and essential product that plays a crucial role in various applications. Its high-quality design and efficient performance make it a popular choice for aeration systems around the world.
