FREMONT, CA: Lord Howe Island, a World Heritage site that is barely 11 kilometers long and two kilometers broad, is implementing not only current wastewater, green energy, and island-wide clean-up and insect eradication projects but also hopes to reintroduce flora and wildlife that have been missing for decades. The island is 400 miles off the coast of New South Wales, Australia, and is controlled by the Lord Howe Island Board, which is a statutory body. It is located in the Tasman Sea region of the South Pacific Ocean, with a population of about 400 people and a limit of the same number of tourists on the island at any given time.
Residents on the island have launched an environmental movement in recent years. The movement goals include removing all invasive or undesired species, using solar power to meet two-thirds of the community's annual energy demands, and obtaining EPA certification to compost solids from the island's environmentally sensitive, low-energy wastewater treatment plant. The plant is part of a larger project to update the island's sewerage management system, including roughly 220 septic tank systems, 25 of which are tied to commercial operations. To dewater the sludge from the tanks, it was previously collected and put on drying beds. The process was stinky, required a lot of handling, and may take a long time to finish, especially if the weather was terrible.
CST Wastewater Solutions (CST), an Australian and Asia-Pacific wastewater treatment company, has built a new solid-liquid separation system from Kendensha Co. (KDS) as part of a more extensive wastewater treatment system. The system employs long-lasting, low-maintenance liquid-solid separators that provide output that is light, clean, and easy to handle. A 1,800-liter wastewater tanker transports sludge from septic tank pump-outs to the new waste treatment facility. After passing through coarse and fine screens, the effluent is piped to a polymer dosing tank. A spreadsheet assists in determining the polymer dose and forecasting the amount of liquid and biosolids produced. These forecasts enable better planning of final product reuse.
