Water Filtration - Bag Vs. self-cleaning

Water Filtration - Bag Vs. self-cleaning

Water Filtration - Bag Vs. self-cleaning

(OP)
We are shortly going to be injecting some cruddy bore water (20,000 bbl/day) into our oil reservoir for pressure support.

At the moment the big debate is whether to go for bag/cartridge water filters or a filtration system that has some degree of self-cleaning ability (self-flush or vibrate).

I can see that self-cleaners don't create environmental waste (no consummables, low OPEX) but on the other hand have more mechanical parts, may be more difficult to operate and have greater maintenance requirements. Bag filters seem simple and reliable but we end up spending time and money using and disposing of filter media.

We are a small operation and don't have an advanced maintenance capability.

A reasonable case can be made for each.

Has anyone had experience with self-cleaning filter systems and found them to be a reliable alternative, or have other opinions, prejuduces with regards to water filtration?

regards
Ant

Hello Antman,

I am working for Twin Filter. We are specialised in automatic selfcleaning filters for water inejection/waterflood. Most of the systems are running on seawater but we have also system on produced water and lakewater.

NOWATA is another manufacturer of pre-packaged backwashable screens/filters. www.nowata.com

If you're onshore and weight and space are not issues, you could consider multi-media filters, which are commonly used if you need smaller than 10 micron filtration.
