Apart from the Environmental necessity of not wasting Water –
There are very good economical advantages
It is expensive to get rid of the dirty backwash water either to sewer or having it removed from site.
It is expensive to replace the water lost during backwash operations.

6. australian water filter Public Swimming Pool Backwash Recycling
Some indicative costs
A large Public pool can use up to 120,000 litres of water per week in backwash operations.*
The cost of replacing this water is up to $25,000.00* per annum
The portion of the discharge levy for sending this water to sewer is $12, per annum
The cost of carting the water away can also be considerable
Additional to these costs are the disposal costs of sludge removal. up to $8,000.00* per annum
Total cost for not recycling this water could be up to $50, per year
Or on a weekly basis approx. $

HOW?

10. water filter
australian
Use an AWF TRITON Recycling Plant

11. australian water filter Schematic TRITON
P.Pat No Improved Water Treatment and recycling process

12. australian water filter
Backwash water is pumped into the main settling Tank

13. australian water filter
Chlorine Dosing Pump adds the correct amount of Bactericide to prevent algae growth in the settling tank

14. australian water filter
The water in the settling tank is left for a predetermined time for the contaminants to settle
The settled water is then drawn off and pumped into the main AquaZEL media filter

15. australian water filter
The water then passes through the Ultra Filter Membranes

16. australian water filter
The next stage is Activated Carbon Filtration to remove the hidden Contaminants such as Volatile Organic Compounds

17. australian water filter
The next stage is to add chlorine to the water to enable a residual to be tested prior to returning the bulk of the Backwash Water to the pool for reuse.

18. australian water filter
The Backwash Water is then disinfected using Ultra Violet to ensure absolute bacterial control prior to returning the water to the pool for reuse

19. australian water filter
A Reverse Osmosis unit can be provided as an optional extra to allow a side stream of treated water to lower TDS in the final water returned to the pool if required.

At calculated intervals (determined for each system depending on volumes etc), the Main media tank is backwashed and the waste is pumped into the sludge pit. The water used for backwashing is taken from a clean water connection
Clean Water

At calculated intervals (determined for each system depending on volumes etc), the Ultra filters are backwashed and the waste is pumped into the sludge pit. The water used for backwashing is taken from a clean water connection, the appropriate chemical cleaner is injected as required

23. australian water filter
At calculated intervals (determined for each system depending on volumes etc.) the sludge in the bottom of the settling tank is pumped into the sludge pit via a chlorine neutraliser, aerated and then treated with microbes.

24. australian water filter Sub Soil Irrigation
The Treated sludge which after about four days is the consistency of dirty water can be pumped through sub surface irrigation for lawns or garden beds
