Q What is an Ozzi Kleen SC20?
Answer An Ozzi Kleen SC20 is a containerized domestic wastewater treatment plant with a standard capacity of 100 people or 20,000 liters per day.

Q What does it do?
Answer It treats all your wastewater/sewage, i.e. kitchen, bathrooms, toilets, laundry, etc

Q How does it work?
Answer The Ozzi Kleen SC20 works on an aerated cyclic process (extended aeration - activated sludge).  When the air blower is in the on mode diffused air is worked into the sewage breaking down the matter.  When the air blower is in the off mode the biomass settles to the bottom and the decanter slowly sinks into the water and draws the clear water off the top.  This decanted water then passes over the chlorine tablets in the chlorine dispenser and goes into an effluent holding compartment.  When this compartment is full, a float switch turns the effluent pump on and then pumps the treated water out through the irrigation line onto landscaped gardens.

Q Do you install?
Answer The price quoted for SC20 is generally including supply, installation and commissioning of the system.

Q Does the Treatment Plant smell?
Answer Due to the oxygenated active biomass there is no odorous processes involved.

Q Can you get infections from the irrigated water?
Answer The treated water quality has to conform with the Australian Standards AS1547.  Chlorine is used for disinfection which is an accepted practice in both small and municipal treatment plants.  A sign is provided with each plant to place in the irrigated area, warning "Do Not Drink".

Q What type of chlorine is used?
Answer Calcium hypo chlorite in tablet form.

Q What sort of warranty is given?
Answer Normal twelve months defects liability, from date of purchase.

Q How often does the Treatment Plant have to be serviced?
Answer The Local Government requirement asks for a service every 90 days with a full report of water quality to be submitted to them.

Q What do you do when servicing?
Answer Various tests are taken for the water quality.  Chlorine is replaced in the dispenser.  Any adjustments are made to have the plant performing correctly.  Reports are submitted to the council.

Q What sort of things can or cannot be put into the system?
Answer The use of bio-degradable and phosphate free products are more friendly to the environment but you can use your favourite brand of cleaning products.  Do not put any foreign matter in the system that is non-bio-degradable.

Q What is activated sludge?
Answer Activated Sludge is floctuated organic matter which contains the active biomass that performs the treatment of incoming sewage in an oxygenated environment.

Q Does the Treatment Plant need pumping out or desludging?
Answer Under normal circumstances the Treatment Plant should never be pumped out as desludging is not necessary.  Our authorised Treatment Plant Operator who performs the service will check for sludge levels, which is one of the tests that is carried out during servicing.

Q What is a cyclic process?
Answer The cyclic process consists of three stages:
1. Digestion of the organic waste.
2. Settling of the active biomass.
3. Decanting of the clarified effluent through a chlorinator providing disinfection of the final treated water before irrigation.

Q Does the irrigation water smell?
Answer No.  An oxygenated treatment process does not allow for any septic process to take place which can produce dissolved sulphides and other odours.

Q What are the nutrients that get released in the irrigation water?
Answer There is a low level of nitrates because of the denitrification within the process.  Phosphates can exist because the household is using products that contain phosphates.  Phosphates also come from vegetable matter.

Q What happens to phosphates?
Answer Plants and trees use phosphate during the process of growth converting it to plant tissue.

Q What is grey water?
Answer Grey water is all your household waste water not containing the toilet connection.  Grey water when stored for 12 hours is equal in bacterial content of normal raw sewage.  Grey water consists of half of the biochemical and bacterial loading of sewage and according to the Environment Protection Authority is considered the same as black water or sewage because it has similar high levels of bacteria.
