Thought you all should know.

Well, I got the call today(3-23-11) All Purolite resin will have a surcharge of .94 cents a pound. Quote " Unrest in the Middle East and North Africa has driven the price of oil over $100/bbl" " In order to maintain the health and strength of our company during this inflationary period, effective immediately, Purolite is adding a raw materials surcharge to all orders" " once costs go down the surcharge will be removed. Thank you for your understanding during these unstable times"

Sincerly, Jacob Brodie, Vice president, Purolite Company- Division of Bro Tech Corp.



I think thats a bunch of crap. Oil has been high like this before and no surcharge.

Wood chips here I come.

Yep. I got the same thing on this end.
"Spike in oil prices has shot the price of Purolite up".
Uh huh...sure....and that huge stockpile of Purolite they've got sitting at the factory just "magically" jumped in price. LOL!!

Guess they're taking cues from the oil companies.

When I started 4 years ago, I employed Graham's 5% pre wash, de-meth, settle, and twin 8"X 60" PD206 towers. After 5000 gal., my PD206 is contaminated. So, I added a chip barrel, and all is well again.
I'm wondering if I should purge clean the PD206, buy new, go to Thermax, or just abandon the towers and use chips. I process about 1200-1500 gal/yr., and chips are free and plentiful. Did I just answer my own question?

I am useing DWR10 in a 12 inch tower. Lots cheaper than Purolite, A little slower feed rate though. I also have a sawdust,wood chip, planer shaving tower. ( whatever I can find) That also reduces the contamination in the DWR10. I belive a chip tower is a must have. Resin is way to expensive to load up after 1000 gallons in a 12 inch diameter tower with 125 pounds in it. I may be going to all wood shavings after my resin tower is loaded again.

Ditto what Ian said.

I'd also say to purge your PD-206 with a methanol wash.
That way you can rinse out the media and should be good to go again plus with wood chips in front of them they'll last even longer.

If you set up a chip drum in FRONT of the Purolite it will last a very long time. Of course the other parameters must also be met; proper demething of the fuel before it goes through the media. The more you ask the media to do the shorter its life span.

Thank you for the replies.
Since I already have the resin towers, I'll purge clean, and use the chip barrel in front.

lose the resin towers once you have used up whatever media you have in stock.

Move to all woodchip using three barrels in series and you will have shiny clean bio without demething or expense. Change barrels and rotate ie burn barrel one contents for heat, make barrel two barrel one, make barrel three barrel two, refill barrel one with new wood and make barrel three. Works great. lifespan of first barrel vastly shortened by not demething but works out path of least resistance and cost for me.
