CERTIFICATE OF TYPE APPROVAL
FOR SEWAGE TREATMENT PLANTS
|
|
|
|
| This is to certify that the sewage treatment plant, type
............................................................. , having a
designed hydraulic loading of ............ cubic metres per day,
(m3/day), an organic loading of ............ kg per day biochemical
oxygen demand without nitrification (BOD5 without nitrification) and of the
design shown on drawings Nos. ...................................manufactured
by ..............................................................
|
| has been examined and satisfactorily tested in accordance with the
International Maritime Organization resolution MEPC.227(64) to meet the operational requirements
referred to in regulations 9.1.1 and 9.2.1 of MARPOL Annex IV, as
amended.
|
|
|
|
| The tests on the sewage treatment plant were carried out
|
| ashore atfootnote

|
| and completed on
................................................................................................................
|
|
|
|
| The sewage treatment plant was tested and produced an effluent which, on
analysis, produces:
|
|
.1 a geometric mean of no more than 100 thermotolerant
coliforms/100 ml;
|
|
.2 a geometric mean of total suspended solids of 35 Qi/Qe mg/l
if tested ashore or the maximum total suspended solids not exceeding (35
plus x) Qi/Qe mg/l for the ambient water used for flushing
purposes if tested on board;
|
|
.3 a geometric mean of 5-day biochemical oxygen demand without
nitrification (BOD5 without nitrification) of no more than 25
Qi/Qe mg/l;
|
|
.4 a geometric mean of chemical oxygen demand (COD) of no more
than 125 Qi/Qe mg/l;
|
|
.5 pH between 6 and 8.5;
|
|
.6 a geometric mean of total nitrogen of no more than 20 Qi/Qe
mg/l or at least 70 per cent reduction; and
|
|
.7 a geometric mean of total phosphorus of no more than 1.0
Qi/Qe mg/l or at least 80 per cent reduction.
|
|
|
|
| The Administration confirms that the sewage treatment plant can
operate at angles of inclination of 22.5° in any plane from the normal
operating position.
|
|
|
|
| Details of the tests and the results obtained are shown on the appendix to
this Certificate.
|
|
|
|
| A plate or durable label containing data of the manufacturer's name,
type and serial numbers, hydraulic loading and date of manufacture should be
fitted on each sewage treatment plant.
|
|
|
|
| A copy of this certificate should be carried on board any ship
equipped with the above described sewage treatment plant.
