Using magnetism to separate the magnetic functional powder from the suspended solids achieves reductions in both the chemical-derived sludge and the cost of waste disposal, and also allows valuable substances in the suspended solids to be recovered with a high level of purity. Running costs are also substantially reduced, because the separated and recovered functional powder can be circulated and reused within the system.
The Toshiba system is already being used at Fujitsu Ltd’s printed circuit board plant in Nagano, Japan.
“Toshiba’s non-chemical feed filtration offers high performance water treatment without the use of coagulants. It has already met the stringent requirements of Fujitsu, and we now plan to introduce it throughout Asia, where it can contribute to cost efficient operation and to environmental protection,” said Toshiba’s Naohiro Noro.
Toshiba will introduce the new non-chemical feed filtration system at the Singapore International Water Week 2012.
