PROJECTS
Aeration of Sewage Lagoon Systems
- VIC Water Authority
Client required increased aeration to treat the increasing BOD and also adopted the automated bacteria dosing system to ensure correct biological process. Also issues with aging mechanical surface aerators. - NSW Shire Council
Ponds 1 and 2 had significant sludge build up and Council required an environmental and more economical solution than centrifuge and landfill disposal. The For Earth system provided biological sludge reduction and long term treatment results. - VIC Water Authority
Client required increased aeration to treat the increasing BOD and also adopted the automated bacteria dosing system to ensure correct biological process. Also issues with aging mechanical surface aerator. - NSW Shire Council
Carryover nutrient from treatment plant causing sludge build up in ponds and severe algae blooms. Automated bacteria dosing and sub-surface diffusers installed at inflow and discharge points of ponds. - VIC Water Authority
Population growth and the construction of the desalination plant was impacting on influent loads. Client required increased aeration to treat the increasing BOD and also adopted the automated bacteria dosing system to ensure correct biological process. - NSW Shire Council
Treatment consists of oxidation ponds and final water is stored for reuse. Council wished to improve the final water quality before discharge to storage dam. Installed For Earth sub surface diffusers prior to discharge. - NSW Shire Council
Carryover nutrient from treatment plant causing sludge build up in pond and severe algae blooms. Sub-surface diffusers installed at inflow and discharge of pond. - NSW Shire Council
Oxidation pond 1 had significant sludge build up and overall treatment was decreasing causing water quality issues at discharge. For Earth aeration installed at inflow zone before baffle. Bacteria being auto-dosed into upstream pump station.
Aeration of Water Supply Dams
- Membrane Filtration Water Treatment
Plant
Aeration of Water to improve Dissolved Oxygen Levels - NSW Regional Council
Regional Council had an issue with their water supply dam experiencing algae blooms and stratification. Council engineer designed an aeration system using For Earth diffusers and compressed air system (200kpa) to drop the diffusers subsurface levels 2 – 8m deep.
Aeration of Landfill leachate ponds
- NSW Regional Council
The For Earth aeration system, coupled with For Earth pro-biotics are used within the leachate dam to control any odours generated from leachate management practices. Leachate can also be discharged to sewer. It has the added benefit of ongoing biological sludge reduction. The treated leachate will also aid in reducing odour when recycled through the tip face. - NSW Regional Council
The For Earth aeration system, coupled with For Earth pro-biotics are used within the leachate dam to control any odours generated from leachate management practices. It has the added benefit of ongoing biological sludge reduction. The treated leachate will also aid in reducing odour when recycled through the tip face and compost. - NSW City Council
For Earth Low energy aeration system installed to improve water quality and eliminate odour. - NSW Council
The For Earth aeration system, coupled with For Earth pro-biotics are used within the leachate dam to control any odours generated from leachate reuse and irrigation on capped cells. The process has the added benefit of ongoing biological sludge reduction.
Small Wastewater Treatment Plants
- NSW Shire Council
Effluent is collected from the truck wash in an effluent pit and large solids are screened. Screened effluent is then transferred to a holding tank which is then transferred to the Bio- Reactor. The Bio-Reactor consists of 3 poly tanks in series. Each tank has aeration and biological dosing. The system will provide ongoing biological sludge reduction and odour control. Water quality improves as it passes through each bioreactor tank until and treated effluent gravity flows to storage pond to be held for irrigation. - NSW Shire Council
Effluent is collected from the saleyard floor in an effluent pit. Then effluent is pumped to first flush tanks (tanks 1 & 2). This is then pumped to the Bio- Reactor. The Bio-Reactor consists of 3 tanks. Each has aeration and biological dosing (tanks 3, 4 & 5). The system will provide ongoing biological sludge reduction and odour control. Water quality improves as it passes through each tank until it reaches final tanks (6 & 7) where it is held for irrigation or discharge. Complies with EPA limits. - Livestock Exchange
Effluent is collected from the saleyards and truck wash. It passes through a solids trap that removes the bulk of the solids before pumping the effluent to the Bio- Reactor. The Bio-Reactor consists of 3 tanks x 2 series. Each tank has aeration and biological dosing. The system reduces odour issues. Treated effluent parameters have been below Council tradewaste levels since installation. - NSW Shire Council
Effluent is collected from the truck wash. It passes through a solids trap that removes some of the solids before gravity feeding to the effluent ponds. The aeration system has been installed into both ponds. This has provided ongoing sludge reduction and improved water quality for irrigation. - NSW Shire Council
Effluent is collected from the truck wash. It passes through a solids trap that removes some of the solids before gravity feeding to the effluent ponds. The aeration system has been installed into the first pond. This pond is manually dosed with For Earth Bio©. This has provided ongoing biological sludge reduction and improved water quality. - NSW Shire Council
Effluent is gravity fed from the truck wash to the effluent ponds. The aeration system has been installed into the first pond. This pond is manually dosed with For Earth Bio™. This has provided ongoing biological sludge reduction and improved water quality for irrigation.
Biological Sewage Sludge Removal
- NSW Shire Council
Installation of For Earth low energy aeration system and bacteria dosing system. - Snow Resort
Existing sludge holding tank requiring regular pump outs. Solution: Sludge is wasted from the sequence batch reactor tanks during the aeration phase to aerobic sludge digestor 1 which gravity flows to aerobic sludge digestor 2 and back to inlet works. Tanks are sub
surface and insulated to increase operating temps. - Regional NSW Council
IDEA treatment process, WAS transfer to storage ponds filling quickly, difficult to organise pump outs. Client installed the For Earth Aeration and bacteria dosing system to desuldge online sludge pond. Client has been able to extend sludge storage pond to 2
years instead of 9 months before mechanical removal. - NSW Regional Council
IDEA treatment process, WAS transfer to storage ponds filling quickly. Client installed the For Earth Aeration and bacteria dosing system to desuldge offline sludge pond. Change system over every 8 months. Monitored VS% and after 5 years ponds have had their first sludge removed mechanically. (very cold climate) - NSW Regional Council
SBR - Client was able to reduce sludge transfer to drying beds by 54% and over the period of 6 months obtained a buffer in the sludge storage lagoons. Client also cancelled a planned $1.5M centrifuge system. System still in operation and achieving considerable
sludge reduction within the ponds resulting in significant cost savings.
