1. Influent pump

The centrifugal pump (Flygt NS 3102.160 SH-256, Figure 3) is used to deliver flows from 5 to 30 m3/h by

controlling the rotation speed of the pump rotor with a frequency controller (Parker AC30). Flows can be set to

a certain value or can be set to simulate a user-defined flow pattern. Water is pumped from the end of the

aerated sand grit, before chemicals are dosed prior to the primary clarifier.

Figure 3 : Centrifugal pump used at the pilot

2. Drumfilter HDF2001-1S

A drumfilter (HDF2001-1S, Hydrotech) with a cloth of 100 µm pores features level control, and an backwashing

system in order to prevent blockage of the cloth. Technical water (max 0,5 L/s) is used for backwashing the filter.

Drawing of the technology is available in appendix 2 of specific verification protocol.

5. Polymer preparation unit

Tomal/Prominent Polyrex 1.0 (Figure 4) is a turn-key automated system for batchwise preparation and metering

of polymer solutions, either powdered or liquid chemicals. PolyRex uses a step-by-step mixing system to

effectively hydrate and mix the polymer to a homogenous and fully activated polymer solution. Powder polymer

is dosed into a tank with tap water by a multiscrew feeder in order to achieve a concentration of 0.1% active

polymer. This solution is maturated with a mixer for one hour and later discharged in a storage tank, where it is

pumped into the main treatment line with a diaphragm dosing pump.

Figure 4 : Tomal polymer preparation unit

The polymer used is H6358: a cationic medium charge high molecular weight powder flocculant supplied by

Hydrex.

6. Polymer dosing

DME 940-4 AR-PP/V/G-S-32A2A2F is a diaphragm dosing pump supplied by Grundfos able to deliver up to 940

L/h at 4 bar (Figure 5). Pressure loading valve is installed in the dosing line to even the dosed flow. The drive

technology and microprocessor control make sure that liquids are dosed precisely and with low pulsation, even

when the pump is operating with high viscosity or degassing liquids. The capacity of the DME is regulated by

automatic adjustment of the motor speed during the discharge stroke, and by fixed suction stroke speed.

Polymer prepared in the polymer preparation unit is dosed directly in the overflow funnel of the coagulation

tank in order to achieve proper dispersion and a concentration of active polymer in the range 2-6 mg/L.

The concentrations of active metal or active polymer can be set by the user at a fixed value or adjusted by the

programmed controller, based on the signal from the turbidity probes.

7. Turbidity meters

Solitax SC ts-line immersion probes (LXV423.99.00100, Figure 6) are installed in the pumping point, flocculation

tank, and filtrate tanks in order to monitor the removal efficiencies of particulate matter. The integrated

automatic wiper allows the probe to remain clean.

8. Flow meters

Promag W 400, 5W4C80 flow meters (DN80, Figure 7) supplied by Endress and Hauser are installed in the inflow

of the Drumfilter and effluent from the Discfilter in order to monitor the water losses in the installation, if any.

The influent flow is used in order to control the rotation speed of the influent pump and the dosing rate of the

flocculant dosing pumps.

9. Measure of SS to control dosage

It is a Solitax turbidity probe (Hach Lange). Infrared Duo scattered light technique for color-independent turbidity

measurement Turbidity in accordance with DIN EN ISO 7027.

10. Backwash water treatment

Backwash water is pumped back to a sludge tank, and later digested in the plant for biogas production.

The Drumfilter is backwashed when required with technical water at max 0.5 L/s. The filter is backwashed

seldomly, so the actual consumption is below 0.5 L/s. Daily consumptions can be monitored. Tapwater is also

used for preparation of the polymer stock solution.

Intended application (matrix, purpose, technologies,

technical conditions)

Intended application

Hydrotech drumfilter HDF2001-1S is used as primary treatment stage for raw municipal wastewater (after

mechanical treatment, i.e. removal of sand, grit and grease) to enable removal of particulate matter.

The high level of carbon extraction of the technology induces high level of biogas production coming from sludge

digestion, so, a good overall environmental footprint.

Matrix

The technology is intended to treat wastewater.

The verification will be performed on a pilot line of Sjölunda Waste Water Treatment Plant. The full address is:

Sjölunda avloppsreningsverk

Spillepengsgatan 15-17

211 24 Malmö

Sweden

The water is received from the greater part of Malmö, together with Burlöv and parts of the municipalities of

Lomma, Staffanstorp and Svedala.

Purpose

The purpose of the technology is to perform a first treatment of suspended solids, BOD, P and COD of the

wastewater with a good overall environmental footprint.

The technology is implemented after sand, grit and grease removal.

Technical conditions

Performance parameters will depend on several technical conditions.

The most important one are described as operational parameters in the paragraph Verification parameters

definitionII.3.

Two scenarios were tested with varying flow conditions varying flow between 6-30m3/h (average is 15m3/h).

For technical reasons it was not possible to use the real inlet flow, so, the flow pattern was fixed by Hydrotech.

The flow pattern is presented in the Figure 8.

Calculation of verification parameters including

determination of uncertainty

Initially, it was planed to use online continuous measurement of TSS.

The online sensors that have been used during the test for turbidity measurement is a Hach Solitax SC

TS-line (for more information see test plan in Appendix 4 : Test plan). The value from the Solitax SC-

probes has been used to estimate the total suspended solids in the water (TSS). To do this a conversion

factor between TSS and turbidity has been calculated from grab samples collected on a weekly basis

during the test period. The conversion factor was then used to estimate the TSS-concentration in the

water from the online-sensors.

We can see in the Figure 9 the curves used for the calculation of TSS performance parameter.

Figure 9 : Correlation between NTU and TSS used for calculation of performance parameter

The on-line values were used to assess the real-time performance of SS-control. The lab samples were used to evaluate the overall weekly SS-reduction. Measurement technical difficulties with the SS-sensor made it infeasible to use the on-line data for evaluating the exact SS-reduction although the time trends were accepted to be valid.

Deviations

The following table shows deviations between tests implementation and specific verification protocol.

Paragraph of the specific verification

protocol

Description of the deviation Criticality Conclusion

II.1 Summary description of the technology Initially, hydrotech planed to use floculant and

coagulant but there was no use of coagulant.

Not critical The modification was accepted.

V.1 Test design

3 scenarios of tests were initially planed.

Each of these scenarios should have been

tested four three types of inflow.

During the timeframe of the program, it was only

possible to perform 2 scenarios with 2 types of

flow.

The scenario “Maintain the effluent at a

continuous 25 NTU concentration despite daily

variations using chemicals” has not been studied.

Not critical The modification was accepted because the low flow

were the most beneficial to the proposer. So, if results

are good for other types of inflow, results should be good

also for low flow.

Deletion of a scenario of test was possible because

results for other scenarios are good. And, it does not

affect the environmental added value of the technology.

V.5.2 Test report All results have been summarized and sent to

Rescoll in excel sheets but no test report has been

written.

Not critical The modification was accepted because the test plan was

very complete and all results were sent in excel sheets.

V.1 Test design

Time period of each test should be 3 weeks

The test period of the scenario « 50 NTU with a

varying flow » was of 1.5 week.

Not critical The deviation was judged as not critical because during

the period of test, there was one period of high flow

which was well controlled by the Hydrotech drumfilter

HDF2001-1S.

V.1 Test design

Continuous measurement

It was planed to use continuous sensors

measurement for TSS performance claim.

Not critical There were continuous measurements of NTU

performed with sensor Hach Solitax SC TS-line of

turbidity.



E382 22/06/2018 I

21/ 34

We checked correlation between NTU and TSS and finally

used the lab measures for the performance parameter

because they were more reliable.

V.1 Test design

Continuous measurement

Calculation of final parameters should have been

based on the whole time period of tests but we

excluded period of time with technical issue

(power failure, …)

Not critical This situation are not due to the technology itself but to

the pilot line scale.

The proposer shall ensure that the verified technology continues to conform to the published Statement of

Verification. This also follows the provisions of ISO 14034, Section 5.6.2 'Validity of the verification

report/verification statement'. If any of the following changes to the verified technology have occurred, the

proposer shall report to the Verification body with the data needed to evaluate whether the conditions for

verification have changed:

change of ownership;

design changes;

change of intended application or operational conditions;

other changes likely to modify the performance results reported in the Statement of

Verification.

Substitution of one part with another with the same documented specifications is not considered a change,

unless it affects the environmental added value or one of the parameters reported in the Statement of

Verification.

The Verification Body shall evaluate reported changes and data at the cost of the proposer. If, after evaluation,

the Verification Body concludes that the conditions for verification have changed, a new verification procedure

shall be engaged by the proposer for this technology or alternatively, the Statement of Verification shall be

withdrawn.

The Statement of Verification shall be withdrawn by the Verification Body if misused by the proposer. Misuse is

defined as violation of the conditions of EU ETV pilot programme verification.

In the case of withdrawal, the Statement of Verification and verification report shall be removed from all web

sites.

In the EU ETV pilot programme, no expiration date is established on the Statement of Verification. However, the

proposer may request that the Statement of Verification and associated report be withdrawn from the web if,

Body, committing to no future use of the Statement of Verification, reference to it or the ETV logo. The

verification Body shall communicate this request to the Commission services and the Statement of Verification

and associated report will be consequently withdrawn from the ETV website.
