1. Overview
ThepuriermeetstherequirementsoftheStateCouncil'sde-
cree (209/2011) 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70comprisestwopurierunits,a.k.a.mod-
ules. The incoming wastewater is divided into the modules by
meansofthebranchsleeve(part7)locatedbetweenthemod-
ules.Bothmodulescontainvelterboxesplacedoneontop
of the other. The wastewater is conducted into the uppermost
lterboxes.Insidethelter,the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
700x1010mm
• two modules side by side: width about 135 cm
• pipe connectors for Ø 75 mm sewer pipes
• heightdifferenceofinletandoutletconnectors(heightoffall):
530 mm
• capacity: about 500 litres a day
• weightwithoutltermaterial:2xabout38kg
2.2 To be located above the ground
The Biolan Greywater Filter 70 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.
3.1 Connecting 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 con-
nectors for 75 mm sewer pipes on both sides of the modules.
The inlet connectors are located at the upper edge and the out-
let connectors at the lower edge. Join the inlet connectors of the
modules together using the connecting pipes (part 6) and the
branchsleeve(part7).Connectthesewerpipecomingfromthe
building to the branch sleeve that joins the modules together.
Thebranchsleevedividestheincomingwastewateroweven-
ly into both modules. To ensure an even distribution, the inlet
pipe can be provided with a straight 80cm-long part before the
branch sleeve, that reduces turbulence of the incoming water
ow.Theoutletconnectorsfortreatedwaterarelocatedatthe
loweredgeofthelter,oneithersideofthemodules.
The treated wastewater can be conducted to the discharge point
either separately from each module or by joining together the
outlet connectors of the modules using an intermediate pipe,
and conducting the water out through the outlet connector of
one of the modules. The outlet connectors of the modules can
also be joined together using a similar branch sleeve that was
used in the inlet pipe. The discharge point for treated wasterwa-
ter can then be located between the modules. The unused inlet
andoutletconnectorsshallbeclosedusingtheplugs(part11)
includedinthedelivery.Ifthelterwillbeusedinwinter,theinlet
sewer must be insulated. Whether also the outlet sewer needs
to be insulated, shall be considered case by case.
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:
3.2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boxbytappingitgently.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.
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.
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, and from there 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-
based insecticide. Consult your local garden centre to select a
suitable product.
