alt-wateranalysis was carried out as a preliminary investigation in designing a drinking water
treatmentplant. Operating conditions such as pressure and flow rate of the plant were selected
accordingto the daily water requirement.
Polypiperazinamide(PA), an aromatic type polyamide used with polysulfone (PS) in 3: 1 ratio
(byweight)to prepare a composite type spiral wound membrane to be used in Reverse Osmosis
(RO) Systemin the plant.
Pretreatmentprocesses reduced Total Suspended Solids and Hardness in water. Electrical
Conductivity,Total Dissolved Solids and Chloride ion were removed using the made RO
membrane.The percentage of rejection of PAIPS RO membrane was 99.9 %. Therefore this
typeof polymeric composite membrane could be used as RO membrane to produce good quality
drinkingwater by desalination of salt water.
