Featured product: PTFE-coated diffusers
------------------------------------------------------

Sometimes, engineers and plant operators have the opportunity to solve 
two problems at the same time -- but it takes an impressive product to 
make that happen. PTFE-coated membrane aeration diffusers are just such 
a product.

These diffusers start with an EPDM rubber base layer, but use a special 
process to add a non-stick PTFE coating. This makes the diffusers 
powerfully resistant to fouling; as a result, they are not only more 
effective at encouraging oxygen transfer to the water (improving the 
quality of the treated water), they also use less energy than dirty 
ceramic diffusers or even membrane diffusers without the same non-stick 
coating.

A clean diffuser is an efficient diffuser, and when you can keep the 
diffuser clean without having to scrub it (or attack it with dangerous 
doses of hazardous chlorine gas), everybody wins. Lower maintenance 
costs and better performance -- it's a double benefit.
