australian water filter Slide 2 australian Public Swimming Pool Backwash Recycling The Average Olympic size swimming pool can use 100,000 litres of water per week in Backwash operations Slide 3 water filter australian There are approximately 2000 Olympic size swimming pools in Australia which would use 200,000,000 litres of water per week in Backwash operations Slide 4 water filter australian Therefore in one year these 2000 Olympic size swimming pools would use 10,400,000,000 ltrs 10.4 Gigalitres Slide 5 water filter australian 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. Slide 6 water filter australian Public Swimming Pool Backwash Recycling Some indicative costs 1.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 annum 3.The portion of the discharge levy for sending this water to sewer is $12,000.00 per annum 4.The cost of carting the water away can also be considerable 5.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 *Figures from Leichhardt Aquatic Centre Slide 7 water filter australian $50,000.00 Per Year Recycling could eliminate these costs $0.00 Slide 8 water filter australian Reuse The Waste Water Slide 9 water filter australian HOW? Slide 10 Use an AWF TRITON Recycling Plant water filter australian Slide 11 water filter australian Schematic TRITONTRITON P.Pat No. 2005903241 Improved Water Treatment and recycling process Slide 12 water filter australian Backwash water is pumped into the main settling Tank Slide 13 water filter australian Chlorine Dosing Pump adds the correct amount of Bactericide to prevent algae growth in the settling tank Slide 14 water filter australian 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 Slide 15 water filter australian The water then passes through the Ultra Filter Membranes Slide 16 water filter australian The next stage is Activated Carbon Filtration to remove the hidden Contaminants such as Volatile Organic Compounds Slide 17 water filter australian 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. Slide 18 water filter australian The Backwash Water is then disinfected using Ultra Violet to ensure absolute bacterial control prior to returning the water to the pool for reuse Slide 19 water filter australian 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. Slide 20 water filter australian 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 RO Flow Control Valve Flow Meter By Pass Inlet Normal Flow Slide 21 water filter australian 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 Slide 22 water filter australian 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 Slide 23 water filter australian 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. Slide 24 water filter australian 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 Slide 25 water filter australian AWFs Commitment to you We Guarantee the performance of the Triton Plant (Up to 98% Reuse of water has been measured) There is a 12month warranty on all equipment supplied by us.
