Test results
UltraClear domestic
systems have been designed to meet the NSW Health Department
Guidelines. All systems were tested at the AWTS Manufacturers
Association Ltd test site located at the Moss Vale Sewer Plant,
with testing program monitored by JAS/ANZ accredited company
SAI Global (previously QAS). Testing in this Southern Highlands
site provided extreme temperature ranges during testing, from
less than -1° Celsius to over 30° Celsius, ensuring the
systems function in all climates, unlike other systems that have
been tested only in warm climates.
An average of over 1,600 litres per day of raw sewage,
with BOD of between 200 and 300 mg/L, was pumped through the system
during testing of Model Ultra 10. The average daily loading of
raw sewage during testing was 1,600 litres for Model ST8 and 2,000
litres for ST10. The average BOD for the single tanks was 183.3
mg/L. The minimum BOD influent required by NSWHD is 150 mg/L. All UltraClear systems
consistently achieved far in excess of the required results during
testing. UltraClear has been proven to remove
over 98% of suspended solids, with removal of harmful micro organisms. UltraClear was
able to achieve these results, whilst maintaining a low chlorine
residual, reducing the impact on your environment. This ensures
that the water irrigated onto your property is clear and safe.
UltraClear systems have been designed
by Darryl Rebbeck, a consultant in the manufacturing industry,
who has had over 16 years experience in the servicing industry
and has a full knowledge of the operation of most types of aerated
systems. The systems have been designed for efficient maintenance
and servicing by providing easy and full access to all chambers
for complete maintenance. This enables the system to function at
optimum efficiency at all times. The single tank systems have inlets
of 550mm for ST10 and 780mm for ST8, which allow for a greater
fall to the tank from the house, for easier installation and also
decreasing the need for risers. UltraClear systems
are manufactured using concrete tanks and baffles manufactured
by UltraClear AWTS Pty Ltd trading as Highland
Concrete Tanks, at 17 Drapers Road, Braemar, to comply with Australian
Standards to AS/NZS 1546.1:1998. NSW Health Department Certificate
of Accreditation No. CofA 005-20582 and StandardsMark Licence SMKB20582.

- Biochemical Oxygen Demand (BOD) BOD measures the amount of
organic matter in effluent. The lower the test result the cleaner
the water.
- Suspended solids measure solid particles
in the water.
- Free Residual Chlorine
measures the amount of free chlorine remaining in the water
prior to irrigation. The lower the reading, with a low faecal
coliform reading, the more efficient the system.
|
- Faecal coliforms measure the amount of harmful
pathogens in the water. Ultra Clear achieved almost total elimination
of harmful pathogens with an average reading of 0.1 cfu/ml.
The lower the reading, the clearer and cleaner the irrigated
water.
- Dissolved Oxygen measures the amount of
oxygen diffused into the water by the air pump. The higher
the reading, the more efficient the method of air diffusion.

BEFORE PURCHASING A SYSTEM ASK TO SEE THE TEST RESULTS
to ensure you are choosing a system that has been proven to deliver
superior results. |
