To achieve a system which is reliable, affordable
and positive for our environment, South Australian manufacturer Ri-Industries drew on its engineering
knowledge and 60 years of experience in producing
concrete tanks and related products.
RI-INDUSTRIES
examined the common type of water treatment system,
which normally uses a concrete tank into which
a separate fibre glass or concrete baffle is fitted
and then sealed.
It was found that sealing in such a design was
not always adequate, so we designed a mono cast
model. With integrally cast baffles, our design
has been extremely reliable under tests.
No untreated effluent can be inadvertently pumped
out into the environment. This of course appeals
to environmentally conscious people, who will
also be impressed by the relatively low cost brought
about by our production methods at RI-INDUSTRIES.
 
Components:
Other
physical features of interest include two aeration
chambers, 12 volt auto reset alarm, automatic sludge and skimmer returns, and a (optional) specially-designed
emergency outlet for effluent should there be
a rare pump failure
Special Features:
The emergency outlet allows liquid to run into
alternative disposal rather than flooding the
system with disinfected irrigation liquid, but
triggers an alarm to alert occupants there is
a problem which requires attention (the warning
time frame is far greater than that of most other
systems).
The feature which really sets the Ri-Industries
treatment system apart from others is the 50 mpa Mono-Cast construction, combined with
REOSHORE POLYPROPLENE STRUCTURAL FIBRE and the highest quality Bio Media Filter.
Customer Attention:
While design and engineering are hallmarks of
Ri-Industries,
so is the company’s “customer first” policy, which accommodates customer involvement
in construction and also incorporates round the
clock service.
Installation:
Ri-Industries can
provide names of master plumbers and registered drainlayers / installers in your area that
are familiar with the RI Treat Systems.
(contact Michael Lademan Aerobic Consultant)
Aspects of installation include agreement on
site drawings, excavation, placement of the system
into the ground, connection of power, setting
up an irrigation system, and landscaping.
Maintenance:
If
used in the correct manner and maintained according
to the recommended schedule, the system will be
effective for more than
30 years.
It is recommended that householders have units
serviced every three months to ensure consistent
performance. Although checks of such things as
pumps, chlorination, aeration and irrigation systems
take place at three month intervals, a full service
(including replacement of certain parts) will
usually only be required every three to five years.
Ri-Industries provides customers with a maintenance
manual which in addition to detailing maintenance
schedules, outlines the remedies whenever certain
problems arise. The Ri-Industries domestic Aerobic
System, however, will normally work continuously
without problems. Most problems of course are
encountered in extreme circumstances, like overloading
with solid wastes and intrusion of things like
rags, newspaper, oils, scraps etc.

How it works:
- All
waste water is gravity fed into primary sewage chambers where it undergoes settlement and digestion
for 24 hours.
Settled waste water then flows into aeration
chambers where air is pumped through in fine
bubbles, providing the distribution of air and
turbulence required for effective treatment.
- Turbulence causes liquids to travel in a circular
motion through bio media which encourages biomass
growth.The biomass assimilates nutrients and
oxygen from the water, leading to a gradual
reduction of impurities as the effluent passes
through the system.
- Effluent and sludge then pass into the settlement
chamber, where the sludge settles to the bottom
before being returned to the primary chambers,
along with the scum which floats in the settlement
chamber.
- Settled effluent passes through the chlorinator
into the irrigation chamber where it is held
for irrigation or other means of disposal.
- Scum and sludge are returned to the primary
chambers by a very effective return system
which keeps the system functioning for up
to three months.
- The return system enables excess sludge
to go back for storage and digestion, suppresses
odour -emitting micro-organisms, and encourages
micro-organisms to be kept at maximum population
levels.
- Problems of the treatment plant not being
used for extended period are reduced.
Specifications:
The
Treatment Tank is manufactured from 50 MPa concrete
in a mono cast process. Baffles, floor and walls
are cast in the one operation using fine tolerance
steel moulds which produce reliable wall thick nesses.
Dimensions : 3250 6 person 2.5 d -2460 h invert 1700 w approx 6.0 tonne
4250 8 person 2.5d - 2760 h invert 2150 w approx 6.3 tonne
4500 9 person 2.5 d -3060 h invert 2200 w approx 7.0 tonne
Tank capacities are:
- primary septic chambers 3,250 litres;or 4250;& 4500 litres
- aeration chambers 2,500 litres;
- settlement chamber 400 litres;
- irrigation chamber 400 litres.
The standard irrigation
pump is a 0.5 kw - 0.75hp single phase Grundfos
AP12 or Lowara Diwa 05 which give a head of some 12m -  14 mtrs and because
of the high quality of effluent being passed through
the system the normal manufacturer’s warranty of 12 months is extended to 3 years
For aeration a ( Japanese) Nitto
85 watt air pump is used. This has been found to
be a very reliable and low power usage , efficient device. (3 year warranty )
Note :
All tanks are water tested for 24hrs before despatch
All tanks come with a 10 year warranty
