particulate emission

particulate emission

(OP)
hi guys

i'm interested in treating a washwater current containing particulate (between 15 and 500 nm)

i'm trying to understand the treatment i have to make.

i read something on marpol annex v: http://www.ukpandi.com/fileadmin/uploads/uk-pi/Doc...

i have 2 doubts:

1) for "cargo residues contained in wash water" and "offshore platforms and all ships within 500 m of such platforms", the discharge is prohibited. well, the question is: i could never ever separate 100% of particulate from washwater... in which terms the discharge is proibited? i guess there is a limit in ppm... isn't it? i don't get it

2) always talking about "cargo residues contained in wash water", but for "ships within (and outside as well) special areas", the charge is permitted... so i could throw out the whole particulate? that sounds strange to me, too...


hoping someone could give me some guidance on legislation about particulate emission in washwater on ships... thanks
