WW filteration

[nilaypathak]

Hello,

I am working on BNR WW plant. This plant is old, built in 88. It has duel media sand gravity filter to treat TSS 10 to 0.15 mg/l. I am looking for vendor or design build company who can offer the engineered technology in this area. Please share your information.

Thank you for your time.

Thank you Bimr,

We replaced media last year. But still we have media migration issues with in filter and loosing media. Engineering firm involved during the study prior to work in 2012 and they recommended replacement of media. We did replace the medial but there is still issues. During the replace they found the media was not reusable thus they have to do disposal. in general they medial can be reuse after washing, that's what medial supplier told us. That's how medial beaten up.
I just took on this project. I realize there are other concerns which lead to cause of problems. for example hydraulic, size of medial and backwash system. I would like to involve qualified vendor.

Thanks again,

The first step would be to contact the manufacturer of the filter. A number of firms made these types of filters. If the firm is out of business, I can recommend another firm.

Not sure if this is the filter, but would expect that the firm would service the legacy brands. Have you contacted Evoqua?
