1. Overview
The Biolan Greywater Filter 125 is a purifying unit for washing
waters,especiallydesignedforweekendresidences.Thelter
purieswashingwatersandwatersfromsaunaaswellasdish-
washingandlaundrywatersintheproperty.Thepuriermeets
the requirements of the State Council's decree (542/2003) on
treatment of domestic wastewater outside the sewer systems of
the waterworks.
Wastewater from a WC or dry toilet in the property must be con-
ducted into a closed tank or treated otherwise in a due manner.
Rain- or stormwater or drainage water from foundations must
notbeconductedintothelter. If installed in accordance with
theinstructions,thetreatmentcapacityofthelterisabout500
litres per day, which in practice meets the need of washing water
for1–5 people.The treatment capacity ofthe lter material is
good for about 100 days, after which it needs to be replaced in
accordance with the maintenance instructions.
Theoperationofthelterisbasedonmechanicalandbiologi-
calltrationofwastewater.Thedirtinthewastewatersticksto
theorganicltermaterialinthelter.Themicro-organismsliving
onthe surface of the ltermaterial use the impurities astheir
nutrition.
TheGreywaterFilter125comprisestenlterboxesplacedoneon
top of the other. The wastewater is conducted into the uppermost
lterbox.Insidethelter,wastewaterowsbygravitationfromone
lterlayertotheotherthroughtheopeningsintheendofthebox.
In Finland, building a wastewater system or chang-
ing it always requires a building or action permission
from the municipal building authority or a submission
of notication of action. The building permission is
applied by submitting a relevant plan.
2. Planning and selecting the
location
2.1 Technical specications
• dimensions of one module: (width x height x depth) 600 x
1230 x 1000 mm
• pipe connectors for Ø 75 mm sewer pipes
• height difference of inlet and outlet connectors (height of fall):
1040 mm
• capacity: about 500 litres a day
• weightwithoutltermaterial:about75kg
2.2 To be located above the ground
The Biolan Greywater Filter 125 shall be installed above the
ground.Placethelterinalocationwherewaterwillnotgather,
evenwhen there is ooding.The ltercan be installed out of
doors without a cover. The unit is thermally insulated, which
means it tolerates slight frost. If the lter is used in winter, it
must, however, be equipped with the Biolan Heating Cable,
whichisavailableasanoption,ortheltermustbeplacedin
a space, where the temperature stays above zero at all times.
The space required for use and maintenance must be taken
into account when selecting the location. A free space, at least
one metre deep, must be provided in front of the unit for chang-
ingtheltermaterial.Asufcientspacemustalsobeprovided
at the sides and the rear of the unit to enable maintenance of
the outlet connector for the sewer and the adjustment of the air
valves in the rear wall. To ensure the supply of oxygen to the
micro-organisms, the air exchange valves must not be covered
or the air exchange must be arranged in some other way.
2.3 Location inside a residential
building
Biolan Greywater Filters are primarily intended for installation
outofdoors.Ifyouareplanningtoinstallthelterindoorsorin
close proximity to a residential building (for example, under the
terrace), then some maintenance space with its own entrance
should be provided. This space must also be provided with a
oorwelloranearthenoorforpossiblemalfunctions.
Thereplacementairforthe lter is taken from the end of the
discharge pipe and the outlet air is conducted as sewer ventila-
tion to the roof of the building. To avoid odour problems, the air
valves of the unit must be kept closed. The outlet air can also
be conducted through the upper air valve in the rear wall of the
lterintoaseparateoutletairchannel.Iftheunitisinstalledin-
doors,theoutletairchannelshallbettedwithanaspiratorthat
maintainsaslightnegativepressureinsidethelter.
Whenever the Greywater Filter is located in a warm
space in a residential building, or in close proximity
to a residential building, the correct installation must
alwaysbeveriedwiththeexpertinchargeofplan-
ning the HVAC system for the building.

2.4 Conducting wastewater to the
lter
Thewastewaterisconducteddirectlytothelteralternativelyby
gravity,byowdrainageorbyapumpwell.Toensureaneven
distribution, the inlet pipe should be provided with a straight
80cm-long part before the branch sleeve (part 7), that reduces
turbulenceoftheincomingwaterow.
If you intend to utilise existing septic tanks during pumping,
these should be in good condition and hermetically sealed. The
operation of the pump must be sequenced using a timer so that
during one sequence the pump will feed at maximum 20 litres
ofwastewatertothelter.Theintervalbetweenthesequences
must be at least 10 minutes. The Biolan Timer, the Submersible
Pump and the Pump Well are available as an option.
2.5 Discharge point for the
wastewater
Conduct the treated wastewater to a suitable discharge point,
for example a stone pocket or an open ditch. When planning,
bear in mind that the discharge of wastewater should be unob-
structed even when the level of the surface water or groundwa-
ter is high. If you route the water to an open ditch, provide the
endofthepipewithaaporanettopreventrodentsorother
small animals from gaining access.

3. Installation
Placethelteronarmandevensurfacethatisnotsusceptible
to frost, such as, for example, a bed of gravel or crushed stone
oracastconcreteslab.Theltermustbeinahorizontalposi-
tionbothlengthwiseandlaterallytoallowthewastewatertoow
smoothlyovertheentirecleaningareaoftheltermaterial.
3.1Connecting the inlet and outlet
sewer pipes
Whileinstallinggravityow sewers,asufcientgradient(of at
least 1-1,5 %) needs to be provided to allow the wastewater to
owwithoutobstructionfromtheseweroutlet ofthehouse all
the way to the discharge point.
There are inlet and outlet connectors for 75 mm sewer pipes on
both sides of the lter. Depending on the requirements of the
location, the pipes can be installed on either side. Connect the
sewer pipe coming from the building to the inlet connector at
upperedgeofthelter.Connectthedischargesewerpipetothe
outlet connector at its lower edge. Close the unused openings
using plugs (product number 571513).
Ifthelterwillbeusedinwinter,theinletsewermustbeinsu-
lated. Whether also the outlet sewer needs to be insulated, shall
be considered case by case.
3.2 Putting the lter material in place
The lter material is packed in plastic bags for transportation.
Removetheplasticbags.Riptheltermateriallooseandspread
it evenly across the boxes by tapping it gently. Resulting from
the packaging method, the bags may contain excessive amount
ofltermaterial.Thellinggradeoftheboxissuitablewhenthe
surfaceoftheltermaterialliesabout2cmlowerthanthebrim
ofthebox.Finally,drawtheltermaterialabout5cmtotherear
from the V-openings in the discharge end of the box.
Theltermaterialboxesareidentical,buttheirdirectionshould
be observed – in the uppermost box water ows towards the
rearwall,inthenextboxitowstowardstheservicedooretc.In
thelowermostboxwaterowstowardstherearwall,fromwhere
it falls along the shaped bottom into the discharge sewer.
4. Use and maintenance
The unit must be used and maintained in accordance with the in-
structions, and its operation must be monitored regularly. Main-
tenance of the wastewater system also involves maintenance of
the pump well and the septic tanks, if provided.
Intotheltercanbeconductedwashingwatersandwatersfrom
saunaaswellasdishwashingandlaundrywaters.Theltertol-
erates a small amount of anti-bacterial or chlorine-based agents
that are commonly used for cleaning. Follow the dosing instruc-
tions issued by the manufacturer of the detergent.
Wastewater from a WC or a dry toilet, rain water or stormwater,
or drain water from foundations must not be conducted into the
lter. Toxic chemicals or substances that contain such chemi-
cals, which can kill the micro-organisms that clean the waste-
water, such as drain openers, paints, oils or solvents, must not
beconductedintothelter.Harmfulchemicalscanbeidentied
from the markings on their packaging:
3.3 Opening the air valves
Theoperation of the lter isbasedonactivityof the micro-or-
ganisms. These micro-organisms need oxygen to survive, and
therefore, it is vital  to provide the lter with sufcient air ex-
change. There are two adjustable disk valves for air exchange in
the rear wall of the modules. Set both disk valves of the module
about 10–20 mm ajar for the summer. In winter keep the valves
only slightly ajar (about 5–10 mm). If you have realised the air
exchange by means of sewer ventilation, keep the air valves
completely closed to avoid odour problems (see point 2.3).

4.1 Follow-up of the operation
Checktheoperationofthelteratleasttwiceduringeveryoper-
atingseason.Awell-functioninglterdoesnotgiveoffastrong
smell,theltermaterialinitremainsmoistandtheexitingwater
isclearandodourlessanddoesnotcontainasignicantamount
of solid matter.
Check that
1. wastewaterisowingsmoothlyinbothmodulesthroughall
the openings of the box
2. theltermaterialhasbeendrawntoadistanceofabout5
cm from the openings in the discharge end of the box
3. the air exchange valves are in the correct position and the
airisowingwithoutobstruction
4. the visible connections of the sewers are in order
5. thepuriedwastewaterisowingfreelyoutofthelter
4.2 Changing the lter material
Normally,theltermaterialoftheltermustbereplacedevery
100 days of operation. Only material, specially intended for use
intheBiolanlters,shallbeusedasltermaterial..BiolanOy
does not guarantee the purication capacity of the unit if any
otherltermaterialisused.
1. Changetheltermaterialofallboxesatthesametime.
2. Open the service door of the lter and draw out the lter
material boxes keeping them in a level position.
3. Emptytheltermaterialintothecompostoruseitascover
soil for ornamental plants.
4. Relltheboxeswithnewltermaterial.Riptheltermate-
rial loose and spread it evenly across the box by tapping it
gently.Finally,drawtheltermaterialabout5cmtotherear
from the V-openings.
5. Check the inlet and outlet connectors for wastewater and
clean them.
6. Returntheboxeslledwithltermaterialtothelterunit.he
ltermaterialboxesareidentical,buttheirdirectionshould
be observed – in the uppermost box water ows towards
the rear wall, in the next box it ows towards the service
dooretc.Inthelowermostboxwaterowstowardstherear
wall, from where it falls along the shaped bottom into the
discharge sewer.
7. Make sure that the unit is on a level both lengthwise and
laterally so that wastewater will be evenly divided into both
modulesandowssmoothlyfromonelterboxtotheother.
8. Closetheservicedoorsoftheltercarefully.
9. Write down the service measures that were taken.
4.3 Storing the lter over winter
Leavetheltermaterialboxesinsidethelter.Freezingofthe
ltermaterialdoesnotdamagetheunit.Iftheltermaterialis
still frozen when the operation starts in spring, thaw it by pouring
warm,clearwaterthroughthelter.
5. Possible malfunctions
The lter material box remains lled with water
Theltermaterialboxshalldrainoffbetweenthetimesofop-
eration.Ifthisisnotthecase,theltermaterialmaybeclogged.
1. Makesurethattheltermaterialhasbeendrawntoadis-
tance of about 5 cm from the openings in the discharge end
ofthebox.Asnecessary,pushtheltermaterialslightlyto
the rear.
2. Checktheageoftheltermaterial.Inheavyandcontinu-
oususe,theltermaterialmaygetcloggedalreadyduring
therst100daysofoperation.Replacetheltermaterial,
if necessary.
Flies in the lter
TheairopeningsoftheGreywaterFilterarettedwithynets
ofsmallmeshsize.Despitethenets,smalliesorgnatsmay
sometimesestablishthemselvesinthelter.Ifiesareinterfer-
ingwiththelter,youcandoawaywiththemusingapyrethrin-
