Appendix VII On-board sewage treatment plant

Test procedure

1 GENERAL

1.1 Basics
The test specification shall be used to verify the suitability of on-board sewage treatment plants on passenger vessels.
In this procedure, the process and treatment technology used shall be examined and approved by means of a test plant. Conformity of the test plant with the treatment plants in service later is assured by applying identical design and dimensioning criteria.

1.2. Responsibility and test location
The test plant for a range of on-board sewage treatment plant types shall be tested by a technical service. The test conditions at the test site are the responsibility of the technical service and must correspond to the conditions specified here.

1.3 Documents to be submitted
The test shall be carried out on the basis of the information document in accordance with Appendix VI, Part II.

1.4 Plant dimensioning specifications
The on-board sewage treatment plants shall be dimensioned and designed such that the limit values specified in Article 14a.02(2), Tables 1 and 2 in their outflow are not exceeded in the course of their operation.

2 MEASURES PREPARATORY TO TESTING

2.1 General
Prior to commencement of the test the manufacturer shall supply the technical service with structural and process specifications of the test plant, to include a complete set of drawings and supporting calculations in accordance with Appendix VI, Part II, and shall provide full information on the on-board sewage treatment plant’s requirements in terms of installation, operation and maintenance. The manufacturer shall supply the technical service with information on the mechanical, electrical and technical safety of the on-board sewage treatment plant to be tested.

2.2 Installation and putting into service
For the purpose of the test, the manufacturer shall install the test plant in such a way as to correspond to the intended installation conditions on board passenger vessels. Prior to testing the manufacturer must assemble the on-board sewage treatment plant and put it into service. Start-up must be in accordance with the manufacturer’s operating instructions and shall be checked by the technical service.

2.3 Run-in phase
The manufacturer shall notify the technical service of the nominal duration of the run-in phase up to normal operation in weeks. The manufacturer shall specify the point where the run-in phase is deemed to be complete and testing may commence.

2.4 Inflow characteristics
Domestic raw sewage shall be used for testing the test plant. The inflow characteristics as regards pollutant concentrations shall be obtained from the on-board sewage treatment plant manufacturer’s dimensioning documentation in accordance with Appendix VI, Part II by forming the quotient for the flow rate of organic substances in the form of a BOD5 load in kg/d and the design flow rate of sewage Qd in m3/d. The inflow characteristics shall be set accordingly by the inspection body.

Formula 1 Calculation of the inflow characteristics
CBOD5,mean = BOD5QdkgBOD5 / dm3 / d
Should application of formula 1 result in a lower average BOD5 concentration of less than CBOD5mean = 500 mg/l, at least a mean BOD5 concentration in the inflow water of CBOD5,min = 500 mg/l shall be set.
The technical service must not break up the inflowing raw sewage in a comminatory. Removal of sand (e.g. by screening out) is permissible.

3. TEST PROCEDURE

3.1 Loading phases and hydraulic feeding
The test period shall comprise 30 test days. The test plant shall be fed on the test field with domestic waste water in accordance with the loading specified in Table 1. Various loading phases shall be covered, with the test sequence taking account of normal loading phases and special loading phases such as overload, underload and stand-by operation. The duration of each loading phase (number of test days) is set out in Table 1. The mean daily hydraulic load for each loading phase shall be set in accordance with Table 1. The mean pollutant concentration, to be set in accordance with point 2.4, shall be kept constant.

Table 1
Load settings for each loading phase
Phase	Number of test days	Daily hydraulic load	Pollutant concentration
Normal load	20 days	Qd	CBOD5 in accordance with 2.4
Overload	3 days	1,25 Qd	CBOD5 in accordance with 2.4
Underload	3 days	0,5 Qd	CBOD5 in accordance with 2.4
Stand-by	4 days	Day 1 and day 2: Qd= 0 Day 3 and day 4: Qd	CBOD5 in accordance with 2.4
The special load phases overload, underload and stand-by operation shall be carried out consecutively without interruption; the normal load phase shall be divided into several part phases. The test shall start and end with a normal load phase, of at least five days’ duration in each case.
Daily hydraulic feeding hydrographs shall be set, depending on the specified operation of the on-board sewage treatment plant. The daily hydraulic feeding hydrograph shall be selected in accordance with the plant operation concept for the on-board sewage treatment plant. A distinction shall be made according to whether the on-board treatment plant is to be operated with or without an upstream sewage storage tank. The feeding hydrographs (daily hydrographs) are shown in Figure 1 and Figure 2.
Throughout the entire test period the hourly inflow must remain constant. The mean hourly volumetric flow rate of sewage Qh,mean is equivalent to 1/24 of the daily hydraulic load according to Table 1. The inflow shall be measured continuously by the technical service. The daily hydrograph must keep within a ± 5 % tolerance.

Figure 1 Daily hydrograph for feeding of on-board sewage treatment plant with upstream sewage storage tank

Figure 2 Daily hydrograph for feeding of on-board sewage treatment plant without upstream sewage storage tank

3.2 Interruption or cancellation of the test
It may be necessary to interrupt the test if the test plant can no longer be operated properly due to power failure or the malfunction of a subassembly. The test may be interrupted for the duration of the repair. In such cases it is not necessary to repeat the whole of the test, only the loading phase in which the subassembly malfunction took place.
After the test is interrupted for a second time, the technical service shall decide whether the test may be continued or must be cancelled. The grounds for the decision must be stated and documented in the test report. Should the test be cancelled it must be repeated in full.

3.3 Examinations of purification efficiency and compliance with outflow limit values
The technical service shall take samples from the inflow to the test plant and analyse them in order to confirm conformity with the inflow characteristics. Sewage samples shall be taken from the outflow of the test plant and analysed to determine the purification efficiency and compliance with the required outflow limit values. Sampling carried out shall include both simple random samples and 24h composite samples. In the case of the 24h composite samples, either time-proportional or flow-proportional sampling may be carried out. The type of 24h composite sample shall be specified by the inspection body. Sampling in the inflow and outflow shall be carried out simultaneously and to the same degree.
In addition to the control parameters BOD5, COD and TOC the following parameters for inflow and outflow shall be measured in order to describe and represent the environmental and test conditions:
(a) solids removable by filtration (SRF);
(b) pH;
(c) conductivity;
(d) temperature of liquid phases.
The number of examinations varies according to the relevant loading phase and is set out in Table 2. The number of samplings relates to the inflow or outflow of the test plant.

Table 2
Specification of the number and timing of samplings in the inflow and outflow of the test plant
Loading phase	Number of test days	Number of samplings	Specification of timing of samplings
Normal load	20 days	24h composite samples: 8 Random samples: 8	Sampling at regular intervals throughout the period
Overload	3 days	24h composite samples: 2 Random samples: 2	Sampling at regular intervals throughout the period
Underload	3 days	24h composite samples: 2 Random samples: 2	Sampling at regular intervals throughout the period
Stand-by	4 days	24h composite samples: 2 Random samples: 2	24h composite sample: Sampling after inflow switched on and 24h later. Random sample: 1 hour after inflow switched on and 24h later.

Notes on determining biochemical oxygen demand after five days (BOD5) in 24h composite samples
The International Standards ISO 5815 and 5815-2: 2003 stipulate that in order to carry out the analysis to determine biochemical oxygen demand after five days water samples should be stored immediately after sampling and up to the time of analysis in a brim-full, tightly sealed bottle at a temperature of 0–4 °C. The process of determining BOD5 should be initiated as soon as possible or at least within twenty-four hours of completion of sampling.
In order to prevent biochemical degradation processes starting in the 24h composite sample, in practice the water sample is cooled to a maximum of 4 °C while sampling continues, and is stored at this temperature once the sampling process is complete.
Suitable sampling equipment is commercially available.’
