batteries and rechargeable batteries are also included in the delivery of
products from our range, we would like to point out the following:
Used batteries and rechargeable batteries do not belong in the
household waste, but can be handed in free of charge at the public
collection points of your municipality and everywhere where batteries
and rechargeable batteries of the respective type are sold.
Furthermore, the end user has the option of returning batteries and
accumulators to the retailer from whom they were purchased (statutory
take-back obligation).
Disposal of electronic equipment
Due to the European Regulation 2012/19/EU, your electronic device
must not be disposed of with normal household waste! We will dispose
of your electrical equipment in a professional and environmentally
responsible manner. This service is free of charge, not including
transport costs. This service only applies to electrical appliances
purchased after 13.08.2005. Send the appliance you want to dispose

Dear customer,
at this point we would like to thank you for the trust which you have shown with the purchase of this
product.
On the following pages you will find everything necessary about the installation, operation and the
maintenance requirements of your PUROO® small wastewater treatment plant.
The general information and installation conditions are presented on the first pages with
representations of the PUROO® components in the concrete tank. The details for the installation
can be identified using an example of an installation in a plastic container (Type: Graf).
Please observe that the careful installation of the wastewater treatment plant is very important for a

Brief description of the plant
The water arrives in the pre-treatment stage [1] of the plant for mechanical preliminary purification.
The pre-treated wastewater is conducted via the overflow baffler [2] in to the bottom area of the SB
reactor [3] . In order to avoid possible turbulence of the activated sludge, during the settling phase
or of the clarified water removal, the outlet of the overflow baffler [4] is directed towards the tank
outer wall.
On reaching HWmax the float valve [5] switches over and the settling phase/return sludge feed is
initiated. Short lifting strokes transport the excess sludge into the pre-treatment stage [1] or
subsequently flush the air lift pump [6] using treated wastewater.
With the clarified water removal the outlet of the buffer tank in the direction of the pre-treatment
stage [1] is closed and the treated wastewater is transported via the purged sampling section of the
buffer tank [7] into the outlet.
The overflow baffler is turned in the opposite direction in the intake area [8] of the air lift pump [6],
thus avoiding the influencing of the quality of the discharged clarified water through overflowing
untreated wastewater.
On reaching HWmin the float valve switches over to aeration and a new cycle starts.

General information on installation (using the example of a
concrete tank)
- Partition wall between primary treatment /biology stage must be sealed.
- Tank must be checked for watertightness.
- Cover with ventilation openings or alternative aeration of the plant must be available.
- Empty DN 100 pipe for the control system is laid (max. separation 10 m).
- Max. separation lower edge of discharge pipe to upper edge of partition wall 0.35 m.
(With larger separation the delivery rate of the air lift pump is possibly insufficient.
For queries please call by phone).
- Maximal thickness dividing wall 10 cm
- The opening for the charging of the SB reactor (Ø > 50 mm) must be attached 25-30 cm below
the discharge pipe (below HWmin).

Further prerequisites for the secure operation of the plant
- Empty pipes are to be at least DN 100.
- Cables and hoses in the chambers are to be so mounted that they do not hinder the sludge
disposal.
- Freely moving cables and hoses should not be capable of being damaged by fixed objects.
- A fully functioning ventilation and aeration must be ensured. Normally this is effected by the roof
ventilation and the cover with ventilation openings in the (last) tank or air ventilation in the outlet
pipe. The operational capability is to be documented and verified.
- With underground pipes DIN EN 752 is to be observed and their watertightness is to be verified
in accordance with DIN EN 1610. All pipes (also empty pipes) are to be laid with a minimum
incline > 1% to and from the wastewater treatment plant.
- The pipes are to be sealed at all connections of the wastewater treatment plant. Hoses must be
laid free of kinks and, as for the openly laid pipes, so fixed using clips and und supports that, with
correctly executed work on the plant, they cannot be damaged.
- Inlet and outlet pipelines / openings are to be designed in such a way that blockages and/or
constriction of the free cross-section are not possible.
- With single chamber primary treatment the inlet must be fed through an attached bend opposed
to the overflow baffler in order to prevent a transfer of fibrous materials.
- The discharging of inflammable or other substances which can lead to the formation of an
explosive atmosphere is prohibited (see also Notes on Disposal in the Operating Manual).
- The empty pipe for the control system is to be sealed gastight.
- With the laying of electrical lines the DIN VDE Instructions are to be observed.
- The commissioning of the plant is to take place promptly following the installation or after the first
discharge of wastewater.
- With longer or final decommissioning the plant is to be emptied completely and is to be cleaned.

Installation of the plant components – overflow baffler
The overflow baffler is delivered pre-assembled and is to be pieced together in the tank.
The T-piece [a] with a 90° (2x45 °) bend, attached to the small end, is pushed from the primary
treatment stage through the opening of the partition wall. The bends must be turned into the far
side from the inlet.
With concrete tanks, push the connection [b] from the SB reactor onto the pushed-through pipe
end and secure the connection to the partition wall using a screw. If the plate of the connection sits
flush on the partition wall it is not necessary to seal the opening.
With poly-tanks, the baffler is fed through a lip-seal in the partition wall and does not require to be
attached using the connection.
Attach the T-piece [c] in the SB reactor to the fixed pipe and feed the baffler with the extension to
the bottom of the tank towards a tank wall (separations see diag. below).
The connections must be secured against turning using screws!

Installation of the plant components – preparation of the pipe set
The pipe set incl. buffer tank, is supplied as prepared, flexible plug-in set, which is put together with
little effort before installation.
With the pipe set, as a rule, all standard septic tanks according to DIN 4261 Part 1 with partition
wall can be equipped up to 16 PT. The appropriate technical wastewater calculation is to be
followed.
The pipe set is supplied for partition wall heights > 1.67 m.
With smaller partition wall heights, the pipe set must be shortened at two positions (see marking
diag. left) and the flexi-hose shortened by the difference between 1.67 m and the actual partition
wall height. The suction pipe is to be shortened by a max. of 31 cm (see table below)!
Before assembly remove the transport retaining band on the outlet of the buffer tank!
The pipe set is to be plugged together before installation as shown in the diag. and the pipe
connections are to be secured with a screw.

Installation of the plant components – Installation of the plant
After installing the overflow baffler secure the assembled pipe set to the partition wall using the
5x70 mm screws. The height of the outlet is relevant for the position of the float valve bracket.
The bracket must be so adjusted and secured that the upper edge of the bracket (HWmax) is 5 cm
below the outlet pipe or inlet into the attached bend. (Tip: 5 cm = height of spirit level)
After securing the float valve, check that the flexi-hose moves freely and the float valve moves
freely between lower and upper switching point!
Connect the buffer tank to the outlet of the tank. Arrange the outlet so that, with pumping out, no
water can run back (e.g. attach a 30° bend).
Connect the hose from the air lift pump and the pipe aerators together with the quadruple hose
distributor (diag. above) and lead the air hose together with the float switch lead to the control
system.
The suction pipe can also be turned depending on the position of the overflow baffler (see diag.).
