Peforated Baffles

[TerpsEnviron]

I'm working on the project enhancing the disinfection (chlorination) basin. and and looking for any company manufacturing custom-made plastic perforated baffles, which can be easily installed.
Any helpful information will be appreciated.

Thanks.

This company makes them, but I have purchased from them:

I just contacted the company that bimr suggested. Unfortunately, they do not make any type of baffle walls for disinfection basin.

Thanks anyway.

Thank You bimr!

I contacted Environetics inc. and they manufactures custom made baffle curtains.
I have one more question of which I want hear more objective opinion (other than the company).
How long do these baffle curtains last? (compared to the longevity of plastic baffle walls)
Do anybody know the company manufacturing plastic (solid type) baffle walls?

Thanks bimr again for your help.

I'm not sure that you still need the answer, but the baffle curtains are not real sturdy. Environetics will tell you they last forever. They even use our company in their brochure. But what I've seen of our flexible baffles is that they're poor at any place where you're changing direction of the water. This includes entrances, if the influent is perpendicular to the baffle, and ends where the water needs to turn 180 degrees. Pressures that seem negligible in any other case balloon and stretch these baffles. Eventually, this stretching finds a weak spot and things start popping loose.
Another very worrisome case is filling the basin. If the operators turn loose a slug of water into an empty basin, there's no way to avoid unbalanced forces on the baffles.
I've designed several of these systems. I armor (using block or concrete) all turns and entrances for 30 ft. or so. I run the flexible baffle material between these hardened walls. I also add a six inch concrete curb at the base to mitigate some of the filling forces. And if possible, I make sure there's gaps at the base and edges to relieve some of the pressures.
