The purified recycled water is then pumped to Wivenhoe Dam, where it blends with rainwater runoff stored in the dam. Water is then treated again at water treatment plants downstream at Mt Crosby, before being delivered to homes and businesses. The advanced water treatment plants can produce about 180 million litres a day or about 20% of current ...
Some water treatment plants employ pressure filters. These work on the same principle as rapid gravity filters, differing in that the filter medium is enclosed in a steel vessel and the water is forced through it under pressure.
The water obtained after primary treatment of wastewater is called clarified water. Purified water usually refers to potable water. Sludge refers to solid waste that settles down at the bottom of tanks in a wastewater treatment plant. Sewage is a complex mixture containing suspended solids, organic and inorganic impurities.
