Abstract

The secondary effluent of municipal wastewater was treated with a reverse osmosis pilot plant. The regenerated water was applied to feed water of a low-pressure boiler and its feasibility and economics for reuse were investigated.
Pilot plant tests were conducted for about 14 000 hours, using a tubular module and two kinds of spiral-wound modules. The effect of operating conditions on water flux and water quality through the reverse osmosis membranes and the deposition of scale and/or corrosion in the boiler, etc. were studied.
It was found that the quality of water obtained by the reverse osmosis process was suitable for boiler feed water and the operating cost of a spiral-wound module would be competitive with the use of tap water.
