1h2o3 Skid mounted filtration system for salt water recirculating aquaculture RAS


Hi it’s Nicolas from 1h2o3! today I’m
gonna show you a system that did Paul in the US combining a bead filter with a
skimmer for seafood purpose, for example saltwater recirculated system
for seafood holding system. Just listen to him He explains much better than me without the French accent! Ciao Just want to go over the
anatomy of this whole thing we could talk about where the valves need to be
placed for optimal operation of this skid system okay so water is being
pulled from a sump pump, here, this, return water from the bead filter is coming back here return water from the protein skimmer is right here okay! So let’s
go around to the other side and take a look at how this plumbing is set up okay all right so we’ve got a half horsepower
water pump. Here we are restricting the flow into the bead filter so that we can send
a portion of the flow through the protein skimmer. Now we open this
valve up and keep this valve open all the time. We restrict this flow here to
have a portion of the water going through the bead filter and then another
portion of the water going into the protein skimmer. Water is then
split here at the bottom, there’s a T. 70% of the water goes here
30% of the water goes here We leave this valve open all the time.
This water is running downward through what we call a venturi and that’s
exactly the point at which air is injected. Air is being sucked in through
this port that creates bubbles that are then injected into this column here. The
30% of the water that’s coming through this way is adding dirty water where the
bubbles are going to be catching that dirty water and then flowing upwards. You
see here that bubbling is happening right now This is a clean water
situation but the more proteins you have in the water, the more feed, the more poop, you’re gonna have a lot of foaming out of the top. A cool setup with
this particular protein skimmer is we’ve got a drain right here, we’ve also got a spray bar at the top that will wash all of the foam that collects up in that
column and then that will drain downward into here. So it’s simply opening this valve here, and then allowing that spray bar to spray all the
solids and then having them drain out to a 4 L bucket!
