Super Natural™
How it Works
The waste water enters the system and is separated into two streams.
Solids and a fraction of the liquid drop into the solids composting chamber, which that houses worms and other living organisms. Decomposed solids and some liquid leave the decomposition chamber and collect in the solids pump well. Once the material in the solids pump well has built up to a set level it is pumped out to a subsoil vegetation cell outside the tank, where it can be utilised by a growing plant or plants.
The separator, decomposition chamber and vegetation cell are identical to those used in the Simply Natural System
The bulk of the liquid from the separator flows to a feed tank and then to a bioreactor. The bioreactor consists of a liquid chamber underneath a trickle bed. Liquid is periodically pumped from the liquid chamber and distributed on top of the trickle bed. The relatively large surface area within the trickle bed provides surface area for the growth of bacteria and the treatment of the waste. Oxygen levels are varied by changes in the recirculation on/off times to reduce the level of nitrogen.
Solids building up chamber under the bed are periodically pumped to the decomposition chamber.
A small portion of the recirculating liquid flows to small header tank and then through a booster pump UF membranes a UV unit and a back flush pump submerged in a water transfer tank. The liquid normally gravitates through the system but this flow is aided on occasions by the booster pump. The pressure drop across the membranes is adjusted to ensure there is sufficient flow out of the system at normal loads The membranes are backwashed when the level in the water tank reaches a set level . At the same time liquid is pumped out of the system.
The system alarms if the treatment tank or solids pump well reaches high level or the UV light fails. In this case the system will not pump out. An audiovisual alarm is triggered, as is a signal through the phone line to a remote monitoring site. The audio alarm is fitted with a mute switch that can be operated by the owner. The system continues to send an alarm signal to a remote monitoring site. The Super Natural system is fitted with a battery backup power supply for the operation of alarms in the event of a power loss. High solids and high-level liquid alarm functions remain active during mains power loss, although no pumps are operated.
Benefits
- No Unpleasant Smells: The unique system design ensures no unpleasant odours are released in its process.
- Relatively Low Power Consumption: Approximately 2.1KWhr/day.
- Low Chemical Impact: The system doesn’t use harmful chemicals such as chlorine.
- No Pump-out No de-sludging requirements: Solids are separated and disposed of naturally on site. Ideal for Difficult Sites. The system can be installed under a house or deck.
- Lightweight: Approximately 400kg when empty for easy transportation and installation.
The Super Natural produces treated effluent of high quality that can be surface irrigated and because of the quality used in applications where very high quality water is required.
- BOD5 – less than 10 mg/l
- Suspended solids – less than 2 mg/l
- Faecal Coliforms _ less than 2 per 100 ml
- TKN – less than 10mg · Total N – average less than 20mg/l
- Total P _ average less than 10mg/l
The Super Natural does not use any harmful chemicals such as chlorine. The high quality of the effluent produced from the system and the subsequent low levels of pollutants such as BOD5, suspended solids and no chlorine, means that there is only a positive effect on plants and soil.
The aerobically treated liquid and Vermicast (worm manure) produced from the Super Natural enhances the soil structure. The Super Natural is robust and efficient and consequently only requires two services per year, unlike conventional Aerated Wastewater Systems that require four services
Installation
The Super Natural standard treatment system is housed inside a 3000 litre approved plastic tank ready for connection to the sewer inlet and to mains power. The tank is approximately 1.8 metres in diameter and 1.8 metres high and weighs approximately 400kg.
Aqua Clarus will provide general information on the layout and available options for the vegetation cell and land application area. The exact sizing and location of the vegetation cell and land application area is site specific and should be determined by consultation between the installer (or an Aqua Clarus representative), the local Environmental Health Officer and the client. The land application area must be sub-soil and meet Local Authority requirements.
The Super Natural treatment tank can be installed above ground such as under a house, below ground or partially buried. In the majority of installations, the tank will be installed in the ground as close to the house as possible.
For in ground installation, a hole needs to be excavated prior to installation and suitable bedding material provided. For above ground installation the sewer entry pipe from the house needs to be at least 1.6 metres above the ground and a minimum of 1 metre head height is required above the tank to allow for servicing. The land application area can be some distance from the house.
A licensed plumber is required to connect the system to the sewage outlet from the house and a licensed electrician to run an in ground power supply to the system. (The plumber must be an Aqua Clarus accredited plumber or under the supervision of an Aqua Clarus representative).
Council Approval is required for the installation of the system.
Maintenance
Servicing: Under government legislation, a service agreement is required for all on-site sewerage treatment systems. This ensures that the system is periodically checked for correct operation. For the Super Natural, the inspection period is every six months.
Warranty: The Aqua Clarus Super Natural Wastewater Treatment System is engineered from quality components and installed by qualified people. The system has an expected service life of more than twenty-five (25) years, excluding electrical and mechanical components. The Simply Natural system is covered by a Comprehensive Manufacturers Warranty of two (2) years on all parts and labour.
Accreditation
- Domestic system fully accredited in NSW, ACT, QLD, VIC and SA. Local council approval is required prior to installation of any on-site waste treatment system
