T he method of 'aeratio n by circulation ' with the LRPM is a simple formula that enables natural aquatic life cycle co become a reality in chis new age of high technology. Using a renewable energy source, the LRPM is a cost-effective alternative for water remed iation.
The LRPM is a a wind-operated liquid aerator and circulator (solar and electric available) which req ui res very liccle maintenance. The LRPM has been seen to remediate agricultural, in d ustrial and municipal wastewater, liquid sewage and manure and potable water supplies, and is also used in aquacultu re and the restoration of lakes and rivers.
Another product new on the Australian market is the PTH Water Improver and as che name suggests ic is an improver not a water softener o r fi lter. Used for che prevention of scale and rust, the PTH allows for higher water press ure and supply, greater effi ciency of solar energy systems, and a saving of electricity, gas, maintenance time and money.
In a 24km / h wind, the submerged impeller on the unit has a water circulation rate of up to 9m 3/s. Water fro m as deep as 12 metres is bough t to the surface, helping co eli minate and/o r reduce stratification and allowing a better exchange between atmosphere and sediment. T he LRPM also has a circulating diameter of up to 300 metres.
T he PT H Water Im p rover has also been shown co:
By creating a vertical movement of water, the LRPM allows for a more uniform transfer and distribution of dissolved
The LRPM has been seen to eliminate and/or reduce problems such as: • eutrophicacion; • algal blooms; • odou rs; • fish kills; • mosquitoes; • aquatic weeds; • sludge and silt build-up.
• improve wetting capacity and cleaning potential; • prolo ng the life of pipes; • provide higher water p ressure/flow; • prevent unnecessary oxidatio n; • gradually dissolve and remove existing scale and ruse and prevent reformation. Used extensively for agriculture, domestic and industrial applications, the PTH device can treat water fro m as litcle as 2
