    Oily Water Separation

    By the way...the other thread I mentioned is about half way down page 2 in this section.

    Oily Water Separation

    Hi there Chief, There's been a lot of discussion on this topic in the last year under an older thread that I started when I was researching new separation methods (under 'Oily Water Separation') where a lot of people came forward with useful info and contact details. Ultrafiltration seems to...

    Oily Water Separation On Board Ships.

    Hi rlz, Thanks for the reply. The project is in its advanced stages now and I have already used your company in my research...come across some really quite interesting ideas so far and hopefully there will soon be a major breakthrough!!! Thanks again for replying though, Lis. :-)

    Oily Water Separation On Board Ships.

    Thanks both of you for all this info! I have also come across a lot of info about this ceramic membrane system that the RN and USN trialled...it looks pretty good but I am wondering if they found any shipboard vibration problems with the inherent fragility of the ceramics..I read that they were...

    rbcoulter...re biotreatments

    Hi there! Just another quick question regarding bio treatment of wastewater: What sort of residence times do you think would be needed for a specified throughput? Do you have any figures or sources for this kind of data? Cheers, Lisa.

    Coding System

    I am not sure if I am in the right place to be posting this message, so I apologise if I'm not! I have completed an apprenticeship in marine engineering and have further experience in welding in a manufacturing environment. I have been told by my senior officers that we carry no 'coded welders'...

    Oily Water Separation On Board Ships.

    rbcoulter - thanks for that it is most useful and has really set things into motion this end now!! DeltaCascade - thanks for your ideas too. I don't know what your specialisation is but just in case you are interested in what we do...The reason we don't use centrifugal separation is really a...

    Oily Water Separation On Board Ships.

    Almost forgot... You mentioned that you have knowledge/experience with bio-treatments: I have been reading up a lot about this today and what I have managed to ascertain so far is that some treatments work in 2 stages - initially breaking down oil into smaller globules and then dispersing the...

    Oily Water Separation On Board Ships.

    The problem we seem to have with current separating techniques is that they cannot process all the different types of contaminant and also the fact that the blige water often forms a stable suspension. The sort of contaminant we usually find are monocyclic hydrocarbons, low and high MW...

    Oily Water Separation On Board Ships.

    I am carrying out a research project into new methods for separating oil and water, as found in machinery space bilges on board ships. I am currently researching technologies used shore-side and evaluating their potential for use at sea. I am particularly interested in ozonation, UV exposure...
