Is greywater pasteurisation possible?
(OP)
I don't think it's possible to achieve a high quality of treated greywater from the pasteurisation process.

The ultimate answer to your question depends upon what you are really looking for as a final product. How you get to the end depends upon what you start with.

UV wouldnt work becuase the TSS would hinder the light
When I worked in a research facility for a food company we had nasty bugs that survived 140C temperatures. Not common but they are out there.
Pastuerisation is not enough. Some viruses will certtainly survive.

As far as I found from the websites (not from trust worthy articles yet) greywater pasteurisation is a process using solar energy to heat the greywater up to more than 65-85 degree Celcius for a period of time to remove the pollutants (mostly germs I think). So I agree with Jim Casey about it. I don't think Urea/ammonia is a big problem if your purpose for recycling of greywater is for irrigation.
I think Yogibear1 is right saying the quality of treated greywater you can achieve depends on what's in the greywater. But I don't think we have a choice telling people to use the products that will not pollute the wastewater heavily so that our treatment can handle it;).
Looks like greywater pasteurisation is not very feasible.
