Treatment of mixed (fresh and salt) wastewater
conference contribution
posted on 2018-02-12, 15:11 authored by S.L. Tang, T.H. LeeHong Kong has the geographical advantage of being situated
on the coast and therefore it is possible to use dual
water supply systems (fresh + sea water systems in two
separate distribution networks) for potable and non-potable
uses. From the sea water supply system, about three
quarters of the population in Hong Kong is supplied with
salt water for toilet flushing. The seawater is extracted from
the sea directly and pumped by pumping stations located
near the shore and supplied to the households. The used
toilet flushing water (saline wastewater) is discharged into
the sewerage system which conducts the mixed (fresh + salt)
wastewater into the STW (sewage treatment works). The
salt concentration of the mixed wastewater is between
5,000 mg/l to 6,000 mg/l, about one-fifth of seawater salt
concentration, in Hong Kong.
