  • Filter bag container

    A couple of people have asked me about the container I use to support my filter bags during the filtering process.

    Here are a couple of pix of the Home Brew Fermenter which I use.

    One photo shows the unit with the lid on and the other, off.
    I don't bother about the lid, but someone traveling may wish to use it to keep things neat and limit the oil to inside the filter container while traveling.

    Re: Filter bag container

    Hi Tony,

    I also use a Sock Filter for my BD process, only I pump through mine. My sock filter is considerably smaller in diameter (actually it is 90mm across) and it fits beuatifully in 90 PVC fittings. I made up a canister with screw on ends and plastic welded a fitting the right size to both ends for the inlet and outlet. pump is upstream from the sock, so it is under negative pressure thereby reducing possibility for leaks etc.

    sock filters I think are great as you can easily wash them in warm water and hang them to dry. I have just replaced my first filter which although it is still functioning, I am suspect of it's micron rating. I got over 200 batches out of it. I think they represent excellent value for money when it comes to filters.

      Thanks Cade.
      As you can see, the container is ideal for gravity feed filtering and with the tap, you can replace full clean fuel containers during full flow filtering by turning off the tap, changing container the turning back on again.

      With around 10mm of solid oil built up on the liner, the flow rate drops to around 1 L per day (X2 because I have 2 filters running) but if I scrape the solid fats to the bottom of the liner, I can restore fairly rapid filtering.

      If you are hot filtering, please ensyure that the oil is around 40 - 60°C as the bags can be damaged by excessive heat - they melt at temperatures in excess of around 110°C

      A WARFA member also suggested having a continuous feed to ensure the filter bag remained full of oil while filtering.
      This required a header tank, just above the top of the filter and a rigid plastic plate, just larger then the steel ring in the fiter opening. He bought a hose fitting to suit a tap, one which suits 2 tap thread sizes by providing a reducing bush. He drilled a hole in the plate to suit the reducer thread and screwed the hose fitting together with the plate in between and the hose connection on the top. He connected a short hose from his header tank to the fitting on the plate. Filled the header tank and checked for leaks from the hose and plate/fittings. It worked well from all reports.
      Using a low level header tank was just to ensure maximum filter material area as the oil level drops, and also allows longer intervals between topping up the filter.

      I hope this helps,
      Tony

        A friend put the filter in a length of 150mm pipe and used hose clamps to hold it on/ seal it, with one end of the pipe blocked. Which I suspect is better than what I use.

          I've got a few of these and carry one with a fine kitchen sieve when we travel, so we can refuel where ever we are, they are great for beer and fruit wines as well.

          We are on the look out for a bus to convert and will build a filtering system into it plus carry at least 1000lt. At the moment along with Tim's help, I'm converting a HJ61 12H-T we've picked up with a rebuild motor. It's mechanically in great condition, but the suspension is a mess needing complete re-bushing. So once again the 2H won't get a rebuild, but will continue on it's merry way.

            For the 150mm filter bags I have used a screw on end cap and fitting for 150mm pipe with the filter bag held on with a few hose clamps to make a large loop. A hose barb drilled through the end cap allows it to be constantly gravity fed oil without overflowing.

              I do the same but with 100mm pipe. I gravity feed and keep the bags submerged in my 200l drums in my upflow system. By keeping them submerged in oil no dried up oil can form on the bags inside or out.

                Have you considered the stectch in the bag when you are filtering under pressure ?

                It would be easy for a 5 micron filter bag to filter a low viscosity liquid under low pressure without causing much fibre distortion.

                But Given that clean unburnt oil is around 60x more viscos than water, coupled with the manufactures psi rating on the bags, surley it would be easy to assume that pressure filtering with a bag / sock would inevitably give you a higher micron filtration. And if your oil is sticky , thick and fatty, most likley an even higher one.

                Just a though...

                  Yes that is why I pump to a 25 litre drum up the wall on the shed wall and it gravity feeds from there through the filter.

                    Hi All,
                    I only gravity feed through 5mic filters for the reason outlined above.

                    For a bag holder I use the clear plastic home/office water cooler bottles that sit inverted in the cooler stand. The base neatly cuts out at slightly less than the diameter of the hoop in the filter bag and is retained there well.. The bag neatly hangs inside the bottle and largely doesnt make contact with the inside of the bottle.

                    I have two of these sitting inverted in the top of an IBC. I pump straight from a course filtering/settling drum into the bags with a rotary hand pump....my little bit of exercise every few days.

                      Are you still selling filter bags, If so what size are you using in the fermenter, I am after 1,5 & 10 micron bags and thought you might be the man to speak to. I will be using the same (fermenter) setup as yourself.

                            Pentek increases the pressure capacity of their bag filters by placing it into a screened basket. It means the pressure across the bag can be 15 PSI (1bar) which is not likely to be sustainable without the basket. I have reduced the expenses of my process by back-flushing me bag filters in situ with the gasoline (petrol) that I use to thin my waste oil. This meant I had to reverse the flow of the fluid stream, which meant I had to build an internal basket to keep the bag filter form collapsing inside and/or being pushed backward into the plumbing. See pics below:

                              I have a blue 200 litre drum with 2 holes cut in the top that hold the filter bags just nice. Then a tap on the bottom of the drum for getting the oil out.

                              But sadly I do not use it any more. So if anyone in Adelaide wants it, PM me and you can have it. I think I have 4 unused filter bags to go with it too. You can have them as well.

                              If your feeling keen I have some other 200 litre drums as well.

                              PM me and they are yours free. Other than that they will end up in the skip at work.
