Public Swimming Pool Backwash Recycling

The Average Olympic size swimming pool can use 100,000

litres of water per week in Backwash operations


There are approximately 2000 Olympic size swimming pools in Australia which would use 200,000,000 litres of water

per week in Backwash operations


Therefore in one year these 2000 Olympic size

swimming pools would use 10,400,000,000 ltrs

10.4 Gigalitres


Apart from the Environmental necessity of not wasting Water –

There are very good economical advantages

1. It is expensive to get rid of the dirty backwash water either to sewer or having it removed from site.

2. It is expensive to replace the water lost during backwash operations.


• Public Swimming Pool Backwash Recycling• Some indicative costs1. A large Public pool can use up to 120,000 litres of water per week

in backwash operations.*2. The cost of replacing this water is up to $25,000.00* per annum3. The portion of the discharge levy for sending this water to sewer

is $12,000.00 per annum4. The cost of carting the water away can also be considerable5. 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 $50,000.00

per year • Or on a weekly basis approx. $1000.00

HOW?

Use an AWF TRITON Recycling Plant

TRITON

P.Pat No. 2005903241 Improved Water Treatment and recycling process


Backwash water is pumped into the main settling Tank


Chlorine Dosing Pump adds the correct amount of Bactericide to prevent algae

growth in the settling tank


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


The water then passes through the Ultra Filter Membranes


The next stage is Activated Carbon Filtration to remove the hidden Contaminants such as Volatile Organic Compounds


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.


The Backwash Water is then disinfected using Ultra Violet to ensure absolute bacterial control prior to returning the water to

the pool for reuse


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.


The Flow control valve can be adjusted to control the amount of water sent through the RO Unit as a side stream.

The flow meter gives the indicated rate through the RO

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

Clean Water


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.


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
