Water Treatment "Part 40": Wastewater.

Water does not simply disappear after use; rather, it gets increasingly contaminated; so, waste water and water supply cannot be considered separately. In order...

Water Treatment "Part 39": Precipitation.

Precipitates can be divided into two categories: - 1- The separated particles, which have a constant leaking velocity, are included in the first category. - 2- ...

Water Treatment "Part 38": Zeta potential and colloidal system stability.

The Zeta potential, or the rate of electrostatic migration, has an impact on how stable a suspended particle is. Zeta potentials for unstable suspensions are le...

Water Treatment "Part 37": Colloidal particle interaction in an electrolyte solution.

There are two main groups for colloids in water: 1- Hydrophilic colloids: Hydrophobic colloids in natural water form hydrogen bonds with the water molecules. Th...

Water Treatment "Part 36": Coagulation and Agglomeration.

Coagulation: The goal of coagulation is to make the colloidal system unstable by introducing chemicals that may eliminate the forces that are present on the sur...

Water Treatment "Part 35": Water with colloidal and suspended particles.

Among the most significant substances that pollute surface water and must be removed in order to generate drinking water are suspended particles, colloidal soli...

Water Treatment "Part 34": Elimination of fluorine and arsenic.

1- Removing fluorine from water: The majority of fluorine removal techniques used in the process of treatment of drinking water depends on precipitation or adso...

Water Treatment "Part 33": The fundamental methods for eliminating nitrates from water.

There are three fundamental techniques used to remove nitrates from drinking water: - A high affinity ion exchanger for nitrate ions. - The Bioprocess. - Nanofi...

Water Treatment "Part 32": Why activated charcoal is important for treating drinking water?

Water Treatment "Part 31": Water demineralization by ion exchange.

The field of treating drinking water does not employ this technique; rather, it is used in the industrial sector. Three fundamental steps make up the deminerali...

Water Treatment "Part 30": Water softening using ion exchange.

Ion exchangers are used very widely in the field of industrial water treatment. In recent years, following the development of polymers that are impervious to in...

Water Treatment "Part 29": Additional methods for water softening.

1- Water softening with sodium carbonate (Na2CO3): To eliminate water hardness, sodium carbonate can be used alone or in combination with quicklime. In environm...

Water Treatment "Part 28": Water softening with sodium hydroxide.

While both methods aim to soften water, sodium hydroxide has a few benefits over quicklime in this regard: - The reaction kinetics are extremely quick, resultin...
