• Generate purified water that fulfills the more strict needs for industrial use; and

• Treat polluted industrial and municipal wastewater and sewage to make them fit for discharge to public waterways or reuse.

Treating water

Modern-day raw water sources or contaminated wastewater treatment employ various physical, chemical, and biological techniques.

Chemical engineers relate to parting harmful materials from good water as a treatment train. At diverse stages in the multistage treatment procedure, unwanted constituents are separated using the:

• Vacuum or pressure filtration,

• Centrifugation,

• Membrane-based separation,

• Distillation,

• Carbon-based and zeolite-based adsorption, and

• Advanced oxidation treatments.

Activated carbon is a more adsorbent form of carbon generated when heated charcoal. Its intricate internal-pore structure gives an exceptionally high internal surface area. Activated carbon eradicates impurities via adsorption from both aqueous and gaseous waste.

Nowadays, membranes made from cellulose acetate, ceramics, and polymers are used more. The applications come in different innovative designs, comprising tubular, hollow-fiber, plate-and-frame, and spiral-wound configurations. The target of membrane design is to:

• Increase the accessible surface area,

• Smaller membrane pore size (to enable the more precise removal of smaller pollutants),

• Lessen the pressure drop the fluid will arise when flowing through the unit, and

• Recognize more cost-effective system designs.
