Hello Julia, Congratulations on your work. If you could share your contact details to me at ben.ohlmeyer@envirofluid.com I would like to discuss some oppurtunities including https://www.envirofluid.com/eco-friendly-chemicals-solve-sewage-systems-issues-aboard-lhds/ . With NATO regular IMO standards dont always need to be adhered to and we could possibly fix this problem together. Kind Regards, Ben
