Aerated Waste Water Treatment System
What is a BioCycle?
BioCycle is a 4 stage miniaturised waste water system in 1 tank. It
accepts all the waste water from your dwelling, processes the effluent
to a high standard then automatically disposes of it into the ornamental
garden. It is designed to cater for 6-8 people in permanent residence
though larger systems can be custom designed to suit your needs.
While the system removes a percentage of nutrients (nitrogen and
phosphate) it is still rich in these elements and therefore of great value to
flower and ornamental gardens. The garden is regularly watered several
times each day with a small amount of nutrient rich water.
Normally the demand for our system is from people who are unable to
obtain septic tank approval or are not on mainline sewerage. If in the
future, mainline sewerage becomes available then the system can be
removed and re-sold.

Aerated Waste Water Treatment System
How Does It Work?
The reinforced concrete tank is divided into 2 large compartments and 2
small ones.
1. The first compartment is in effect the first chamber of a septic
tank and uses anaerobic bacteria to break down the solids.
The effluent enters the second chamber via a controlled flow
device. This evens out the flow to some extent, e.g.: when a
bath is discharged.
2. The second large compartment has air forced into the
bottom of the tank by the blower. This operation converts the
bacteria to aerobic. There is a quantity of ‘media’ installed
for the bacteria to grow on. The aerobic bacteria chew up
the remaining solids the septic bacteria can’t remove. The
effluent is discharged into the first small chamber (clarification
chamber).
3. Before the now clean effluent enters the pump chamber, it
passes around special chlorine tablets (if the effluent is to be
disposed of in ground then chlorine is not needed). The pump
is operated via a float switch to pump the effluent through
piping then out through sprays and drippers.
Note: 200m2 of irrigation line with sprays are supplied as standard
equipment but we design sophisticated irrigation systems to suit your
application. Alternatives are ‘in ground’ irrigation; above ground dripper
lines or automatic line change either at each pump start or after about 4
minutes of pumping.

Approvals:
Whether the installation is for a new or an existing home, it is necessary
to make an application to your local Council’s Environmental Officer to
install an Aerated Waste Waster Treatment System and obtain a Special
Plumbing Permit.
This approval process may take several weeks depending on various
factors so please keep this in mind when you are planning your waste
water disposal.
Note: It is necessary for us to sight the Council approval prior to installing
our system.
We will provide you with all possible assistance in making your
application.
It is a Council requirement that the system is serviced quarterly. This
cost will either be met by the Customer or the Council, depending on the
Council’s requirements. During this service all aspects of the system are
inspected.

Installation of the BioCycle
Your builder or plumber will advise you of the Council’s requirements
regarding the “fall” from the furthest water outlet of your home to the inlet
of the BioCycle, usually 1-60.
According to the lay of your land you will have a choice for your BioCycle
to be installed in ground, partially out of the ground or standing on a
concrete slab as long as you have sufficient fall.
If the site is so flat that the BioCycle has to be placed deeper in order
that the minimum fall is achieved then ‘risers’ may be required, which will
be an additional cost.
The excavated hole should be 3m x 3m and 2.1m deep. The excavation
needs to be perfectly level in the bottom with 100mm of gravel.

Access To Install The Tank
The tank will be delivered on a large truck approximately 9 metres long
with a Hyab Crane to lift the tank off the truck and lower it into the hole.
The tank weighs 4.25 Tonne with the lid on.
Enough access will be needed for the truck to offload along side the hole
or directly from the rear of the truck tray.
Preparation of a road may be required in wet areas if this is not possible.
Please advise if there are any obstacles or the incline is too steep. We
can then co-ordinate with a large excavator or crane.
Filling the Biocycle Tank with Water
It is most important that immediately after installation of the tank in
the ground that it be filled with approximately 3000 litres of water to
prevent floating.
The water should be inserted on both sides of the baffle in equal
amounts to prevent the baffle shifting sideways!

Irrigation Requirements
The clean effluent is discharged from the irrigation chamber via a 25mm
poly pipe to feed a series of spray heads. These are placed at strategic
positions to suit your requirements. A standard layout can be varied but
will be an additional cost to the customer.
The minimum area to be set aside for irrigation purposes at present
(called the dedicated area) is 200m2. The area maybe any confiquration
provided it adds up to the minimum area in total. This allows for some
innovative landscaping and ensures any new plantings make staggering
growth in the early years. The 2 nutrients Nitrogen and Phosphorus, are
taken up by the soil and plants.
In some situations such as steep, rocky areas, the Health Officer may
require you to terrace the garden and add friable soil and/or pine bark.
Irrigation of recreational areas or vegetable gardens is not allowed.
Under certain circumstances, fruit trees may be irrigated. Discharge to
storm water drains is not allowed, unless by agreement with the Council.
Ideally the dedicated area should have a vegetative cover so that
effluent can be taken up by the plants and evaporated.
Note: The irrigation design is very flexible. We can provide automatic
switching equipment, variable output drippers or combinations or subsoil
(in ground) drippers. These are provided at an additional cost.
Standard Irrigation Kit
BioCycle will install the irrigation
line(s) in a pattern negotiated
with the customer and the
Environmental Officer. If any of
the line is to be buried then this is
the responsibility of the customer
(the customer may have this done
on a ‘do and charge’ basis).
The Final Effluent Quality
BOD (biological demand)
less than 20ppm
SS (suspended solids)
less than 30ppm
ECOLI (bacteria)
less than 10 per 100ml
Free Chlorine
greater than .05ppm
The above specifications are
required under the Act.

Standard Equipment
50m of 25mm poly irrigation line
• 20 short brass spray heads flush with the pipe of 10-20 Dan sprays
sitting in stakes (or a combination, plus drippers)
• Pump head to 5m total (alternative pumps available for greater heights)
• Power Consumption (standard pump) approximately 3 amps (750 watts)
Note: This pump only runs for a short period each day.
The pump is equipped with a float. This starts when the water has risen
to a set level. The pump stops when the water level is low. Higher head
pumps are extra.
Blower Specifications
Blower 70-80litres/min (domestic)
Power Consumption 70-80watts (0.07kw)
The BioCycle Chlorinator
Within the chlorinators a weir has been set and calibrated to enable the
required amount of chlorine to be taken up.
Normally water usage in an average household is 600 litres/day. The
chlorinator canisters hold up to 30 tablets each, which is sufficient tor
6 months use. Normally we only load the canisters for a 4 month period.
This allows a safety margin as we service regularly every 3 months.
Aerated Waste Water Treatment System
Periods of Vacancy
While the BioCycle design allows the system to perform for many months
without any input of waste provided the power is left on, we would like
to be advised if the system will be out of use for longer than 3 months. It
may be advisable to place the system into “sleep” mode.
Alarm and Fail Safe Operation
The customer is supplied with a small alarm plate, which looks similar
to a double light switch. This must be installed by the electrician in a
prominent position within the house preferably in the kitchen where it can
be both seen and heard.
This alarm has 2 red lights and a buzzer. The lights are marked “Water”
and “Air”.
If the water level becomes too high (possible pump failure) or the blower
stops then the buzzer will sound and the appropriate light is activated.
The tank has approximately one days extra capacity if the pump fails
before the system will overflow. Action however needs to be taken
immediately a problem is discerned.
Electrical Circuit Specifications
This aerobic treatment system
requires two circuits, both of
which may be run in the same
24mm conduit.
The conduit must be
run to the terminal box mounted
on the side of
the electrical control box
on the treatment tank.
The terminal box has a
25mm conduit entry.
The circuits required are as
follows:
• A dedicated circuit of 2.5mm
conductor size. Active, neutral
and earth
• The circuit is to connect the
switchboard to the terminal box
on the system
• This circuit must be protected by
a 16amp MAXIMUM re-wirable
fuse or a 20amp MAXIMUM
circuit breaker or H.R.C fuse
• A 1.0mm twin cable connects
the 240 volt alarm plate in the
house to the terminal box
