Filtering waste vegetable oil

An inline filtration system can be used to filter wax free waste vegetable oil using a series of cartridges progressing from 20 micron to 1 micron. Regulation of the pressure over each cartridge is important as the cheaper, melt blown polyester ones are only rated to 0.8 bar and may leak dirty oil if over pressurised. The differential pressure on each cartridge is calculated by subtracting the downstream guage reading from the upstream (wrong way round on the video!) The machine demonstrated has various devices to help regulate and monitor the pressure, including 2 bypass valves and some clever electronics to protect the final cartridge. A better option may be to use 'probond' cartridges that are compatible with the pressures commonly generated by centrifugal pumps. More info at: www.vegetableoildiesel.co.uk

The probond cartridges are brown, if that's any help?

The only improvement I would like to see is what I don't.

Why in the world are the stage cartridges white??

what a load of bollox ya dont need to get into all this nonsense to filter wvo

[siteperfect]

Are the elements cleanable, or do you have to replace them?

can you please illustrate the complete flow diagram of this type.thank you.

I liked the setup. Could you go into more detail about the bypass valve? I understand the rough valve but how does the fine valve automatically adjust. Do you have the supplier or are you in the business of selling the machine. I live in the US so I would have to make it up here. Thanks for the video a very good setup.

To complex mate. Looks impressive just as well.
