Re: Filter bags - bulk offer

I have not had any enquiries from this listing for some time and I no longer carry 5 micron bag filters.
To save me from needing to update prices here, please visit my Gumtree listings for purchase.
Please use your biofuels forum Login name and I will give you a $2 discount on each filter bag.
Please ask for the $5 per bag discount and write "my biofuels forum login name is ........."
Here are my Gumtree Listings:

Hi Tony, are you still supplying the 1-5micron filter bag? If so could you send the price list and payment details please. Cheers Brenden

Re: Filter bags - bulk offer

I need to pass on another price increase from my supplier.
The following prices and filter ratings are available.

Including 500g flat rate tracked Satchel
1 short filter bag (1 micron only) including 500g tracked delivery $23.00
2 short filter bags (1 micron only) including 500g tracked delivery $35.00
1 long filter bag (1 or 5 micron) including 500g tracked delivery $26.50

Including 3kg flat rate tracked Satchel
5 short filter bags (1 micron) including 3Kg tracked delivery $82.00
3 long filter bag (1 or 5 micron) including 3Kg tracked delivery $65.00

This price increase was passed to me in August last year, but I cannot continue to absorb this additional cost.

Re: Filter bags - bulk offer

Is there a articular reason for the 10 micron bag?
If you are doing "staged filtering" then just pre-filter thru tee shirt material. I use a Tee shirt material "Sock" inside the 1 micron filter bags to collect any fats and larger particles. This can be removed and emptied, or simply replaced with another Tee shirt sock.

Tony

Re: Filter bags - bulk offer

Tony, Are you just doing the 1 micron bags as need a 10 micron too.. (the short length bags).

Re: Filter bags - bulk offer

Hey Tony, Those bags have worked well. 1 bag I cut up and made a smaller bag to go around a Baldwin filter, this worked well I could see the fuel being filtered as it passesd from the wash tank to the storage tank, It did block quickly initially as the pump was too far down into the tank. A quick wash of the filter and reposition of the pump and all travelling well now. The second filter I have put in the top of a drum to drain into another drum for all the old fuel around to place, this works well also. Could you tell me how long it would take to filter 20L of WVO through these filter socks? It seems that it would be a time expensive project. Cheers Brenden

Brenden,
That is like asking "how long is a piece of string"?
There are too many variables for me to answer you with any chance of accuracy.
some of these are:
# Oil temperature
# Presence of HMP oils
# Presence of contaminants to be filtered out (Lots of contaminants slows filtering)
# How many litres of oil have passed thru filter already
Etc

I have 3 old filter bags on the go and oil temperature is around 15°C. I can easily filter 20 litres per day using these old filters, but I do need to scrape out HMP oils on a regular basis (every 2nd day) - This means every day, I change out one 20 litre clean oil drum . The next day I change out another drum, and the next day, the 3rd drum gets changed. This oil has been up-flow settled for at least 30 days before filtering.
With warmer oil, with no HMP oils, with new filters you should be able to filter more than 20 Litres per day per filter. Performance will degrade with throughput and with dirty oils.
With relatively clean oil, at 40°C, I can filter 20 litres per hour.
When filtering petrol, I can't pour it in faster than it drains out.

I hope this helps,
Tony

Hi Tony. Just wondering if you still have these filter bags?
THanks

Re: Filter bags - bulk offer

Hey Tony, just a note to let you know the bags arrived yesterday. Now to shape them for the filter and hopefully I'll be filtering the fuel this weekend.
Thank you. Cheers Brenden

Re: Filter bags - bulk offer

Good thinking.
Just be sure to support the bag do that it cannot stretch or rupture due to the pressure involved (probably not much as you are not using a gear pump)
Let us know how it goes.

Tony

Re: Filter bags - bulk offer

Hi Tony, Will follow up the email this week thanks.
To answer your questions re use of the filter bags, firstly its for filtering bio, not oil.
I plan to remove the filter cartridge from a Baldwin tank filter, replace with a stand pipe (downpipe) and loosley fill the bowl with the sock filter. So the fuel is pumped to the bottom of the bowl and is forced through the filter material to the outlet. Hopefully the sump pump that we use will be strong enough to push the fuel through.. Advantages ...replace and wash the filter as required as oposed to replacing the filter each time @$20 a cartridge. thoughts... Cheers Brenden

Re: Filter bags - bulk offer

Brendan,
Thanks for the email. I will reply with my contact and bank details.
How do you plan to use the filter bags? Are you considering pumping thru the bags? If so, you will need a vessel which can support the filter and take the pressure provided by the pump you choose.
Is your oil settled for long before filtering?
Do you cold filter, or heat your oil before filtering?
How much oil do you need per week?

I make 'liners' for the filter bags I use and these will collect any fats which accumulate in the filter. I like to leave at least 2 - 5 mm of fat inside the liner because the fats filter out any flour and other fine particulates from the oil, which otherwise pass thru the filter.
These filters are washable, but the rating will not be as specified after washing (probably one of the reasons Tilly uses a washed bag inside a newer unwashed bag)
If your oil gets a fair bit of high melting point oils, you would be advised to decant the liquid oil from the containers and combine the remaining oils into fewer containers for further settling. In Summer, any remaining HMP oils will make good fuel.

My fuel processing system uses 2 200L drums in an 'Up-flow' configuration and the output from these drums goes to a 3rd 200L drum. from which I pump into the filter bags. Like Tilly, I use home brew fermenters to support the filter bags and the filtered oil flows into 20 or 25 Litre cubies for storage and later, refueling.

I hope this helps,
Tony

Re: Filter bags - bulk offer

Thanks Tilly, Thinking of using the bags as a replacement for the Filter canisters. So hopefully I can clean these easily ! Cheers Brenden

Re: Filter bags - bulk offer

Hi Brendon,
I have a "new" (about 1 years use) 1 micron bag inside an "old" washed 5 micron bag. Both bags are hanging inside an old homebrew black plastic fermenting carboy.
I pour the biodiesel into the top of the filters and collect the filtered biodiesel out of the bottom carboy tap into the 20 litre containers ready for decanting into the Musso.
This spring I will probably remove both filters, turn them inside out and wash them, there is getting to be a lot of debris inside where I pour the biodiesel.
I expect to get another year or three out of them both before replacing one of them with a new 1 micron bag.

I imagine it is warmer here in Paradise because I have not had any problem with filters clogging. Also, if the biodiesel is not clear I do not pour it through the filter.
