Plankton and watermakers

curious to know how others handle plankton up north during the summer. We had a watermaker installed before heading north in the spring (900gpd sea recovery) which has been almost useless as the prefilters clog up after only a couple of hours.

The installed did include a plankton filter before the pre filters but it clogs too fast. The pre filters are the standard type, not the commercial sized models for which space would have been too tight.

The installer is in south florida and not very experienced with plankton issues, the dealer up in Newport said not much can be done.

Looking at the Sea Recovery site, i see they have a media filter, similar to a pool filter that can be backflushed. it looks like it would trap plankton and other solids, hopefully lasting longer (and back flushing is easier than replacing/cleaning 3 cartirdges)

Is this the best option?

Plankton is a big problem in the northeast; we have heard this from many of the boats that cruise in the New England area.

 

The best option that you have is the media filter. That is assuming you have the space, the dimensions are 10 ½ wide 14 ¾ deep and 21 1/8 high. The media filter will filter out any particulate 50 micron and larger, so that should greatly extend the life of your pre-filters. This should take care of the issue that you are having with the pre-filters clogging.

 

Best regards,

Don't know about the NE, but here in the Northwest, we ran one season with the standard filters on our Village Marine 800gpd watermaker and during plankton blooms we couldn't get more than about an hour before plugging the filter. Installed a media filter and haven't had a stop due to a filter plug since. We backflush only every week or so of operation. Highly reccommend them!
