Combination filtration systems
Quite often it is possible to combine pressurised filtration with low pressure or open filtration systems. These hybrid systems can offer the best of both worlds and are quite common.
More often than not the pressurised aspect of filtration takes place on the mechanical filtration side of the filter equation. It makes sense - if you have an old sand filter lying around from your swimming pool system you can have that converted easily into a bead filter.
From this pressurised mechanical filter you can feed an open/low pressure filtration system. So you can combine and make effective use of perfectly serviceable equipment that you already have.
Further options are available to you using pumps - there are situations in which your old swimming pool pump can be called in to do duty in pumping away waster water for instance.
The point is that there are many options available to you. If you are not sure or just need to bounce some ideas around, talk to us and we'll be only too happy to help point you in the right direction.
