Dear Sir/Madam,

We are delighted that you have chosen to buy a modern EPro SBR system. Below you will find

some important information for the safe operation of your system, and for the long term durabil-

ity.

The SBR system is designed to receive all domestic wastewater. Other wastewater, e.g.

from restaurants and / or commercial premises etc., may only be received if this was

specified and taken into account in the system's design.

Biocides, toxic substances or substances which are not biocompatible must not enter

this system because they hinder bacteria important to wastewater cleaning and cause

problems in the biological process (detailed information is provided on the following pag-

es).

To achieve maximum cleaning performance, it is essential that the system is operated in

accordance with our operating and maintenance instructions. You will find these instruc-

tions on the following pages.

We also ask you to read the following information carefully:

The External control cabinets should be located as much in the shade as possible to

prevent them from overheating in the summer.

At all times ensure that the cabinet, especially its ventilation vent, are not covered and

are freely accessible for maintenance work.

External control cabinet: Ventilation vents are situated on the rear of cabinet.

The power supply must be ensured at all times. Please ensure that a dedicated (16

amp) power supplied to the control cabinet. Additional electrical fixtures on the same

fuse / CB may disrupt operation.

2. Safety notices

7 / 46

5. Safety precautions must never be removed or bypassed during normal operation of the ma-

chine. Safety precautions may only be temporarily bypassed or deactivated by an approved

maintenance technician during repairs and maintenance.

6. When working with chemical substances, contact with the chemicals should be avoided as

far as possible. Before these substances may be used, the instructions for use on the pack-

aging or MSDS must be read and followed.

7. If the use of personal protective equipment (safety shoes, protective glasses, gloves, ear

defenders, etc.) is prescribed, ensure that they are used. Defective or damaged protective

equipment must be immediately replaced with fully functional equipment.

8. Work on electrical equipment must only be undertaken by licenced electricians.

9. All safety and danger notices on the machine should always be kept fully legible.

10. Hot parts must not come into contact with explosive or highly flammable chemicals.

11. Do not put vessels containing liquids on electric switch cabinets; short circuits may occur if

the liquid is spilled.

12. The system must not be operated by anyone under the influence of alcohol (remember that

alcohol may still remain in the body the day after consumption!) or medication which limits

cognitive ability or ability to react.

13. The system must be turned off / isolated before any maintenance or cleaning work.

14. Other than for maintenance purposes, the system should always be left switched on, other-

wise efficient wastewater cleaning cannot be guaranteed.

5. Function of the SBR system

13 / 46

Step 3: Settling phase

This step is a rest phase in which no aeration takes place. The activated sludge settles with

gravity (sedimentation phase). A clear water zone forms at the top and a sludge layer at the

bottom. Any floating sludge is on top of the clear water zone.

Step 4: Clear water extraction

In this phase, the biologically cleaned waste water (clear water) is drawn out of the SBR

chamber. It is pumped out by air lift (or mammoth) pump, which uses compressed air. The

air lift pump is designed such that any floating sludge present at the layer of clear water is

not pumped out and a minimum water level is retained in the SBR stage without further

components.

Step 5: Removal of excess sludge

In this phase, excess activated sludge is pumped by an air lift pump from the SBR reactor

chamber to the sludge reservoir chamber, where it is stored. This excess sludge is pumped

out of the base of the SBR chamber.

Once the 5th step is complete, the cleaning process starts again with step 1.

The cycle described above is usually undertaken four times a day. The switching times and

number of cycles can be adapted following discussion with the manufacturer. They may only be

adapted by an authorised maintenance specialist.

The system can also be manually switched to holiday mode.

When in holiday mode, system operation is greatly reduced during long periods without any

supply of wastewater.

Please Note: No waste water is transferred through system in holiday mode.

Feed the suction hose into the precipitant container far enough to ensure suction from

the base.

Connect the suction and pressure hoses to the hose nozzles of the pump and fix them

with the cap nuts.

Switch the phosphate pump on via the menu item ‘Manual Operation’ and check that

the precipitant is sucked in correctly. Swap the hose connections if necessary.

The suction hose can optionally be equipped with a suction lance.

10. Operation and maintenance

33 / 46

approx. 4/6 months). The intervals and work defined by the local water authority in the licence

issued under local government law also apply. The system owner must take out a maintenance

contract with a qualified specialist for this work.

Maintenance should include the following:

Inspection of the operating log to check for correct operation (nominal/actual compari-

son)

Check the air filter on the air compressor and the supply/exhaust air vents on the control

cabinet

Air compressor maintenance according to details provided by manufacturer (see

Annexes)

Function check on mechanical, electro-technical and other system parts key to opera-

tion, such as aerator, lifts, control unit, valves, alarm equipment, ventilation fan, power

cut detector

Check level of sludge in the sludge reservoir. If necessary, the operator / maintenance

provider must arrange for the sludge to be removed (see Item 10.1),

Carry out general cleaning work, e.g. remove deposits

Check the structural condition of the system

Check sufficient aeration and ventilation

Analysis of the aeration basin:

– oxygen concentration (O2/l > 2 mg), if necessary adjust the compressor operating

times

– sludge as proportion of volume (< 400 ml/l) MLSS

If the sludge makes up more than 400 ml/l, the excess sludge return duration

should be increased, in agreement with the manufacturer;

Sampling of final effluent and analysis of the following values when required:

– temperature of wastewater

– substances that can settle TSS

– pH

– odour

– colour

– depth of visibility

– BOD5 (every other maintenance)

10. Operation and maintenance

34 / 46

– COD value

– NH4-N (if required)

– nanorg (if required)

– P (if required)

When maintenance work undertaken, any damage found, repairs undertaken and other infor-

mation should be summarised in the maintenance report by the maintenance company. A suita-

ble template is provided in the Annex. Anything found during the analyses should also be doc-

umented in this report. The system owner / operator should be given the maintenance report so

that it can be passed to the responsible authorities if demanded. The maintenance report should

be attached to the operating manual. Please keep the operating log in a place where it can be

easily accessed.

12. Operating instructions

Basically only substances with the characteristics of domestic wastewater may enter the sys-

tem.

Biocides, toxic substances or substances which are not biocompatible or biodegradable must

not enter the system because they cause biological process problems. The following are not

permitted:

rainwater from roofs and yards

infiltration water (e.g. drainage water)

liquid or solid residue from keeping animals

commercial or agricultural wastewater, unless it is comparable to domestic wastewater

chemicals, pharmaceuticals, mineral oils, solvents

cooling water

solids in the form of food waste, plastics and hygiene articles, coffee filters, bottle tops

and other domestic items

milk and milk products

water discharged from swimming pools

large volumes of blood

If discharging larger volumes of grease or plant-based oils, we would recommend pre-cleaning

the wastewater containing the greases/oils in a grease separator upstream of the wastewater

treatment system (caution: faeces must not be allowed to enter the grease separator!).
