Physical-chemical Treatments

Recommended Prerequisites

Calculus, Physics, Chemistry, Thermodynamics and Phenomena Transport.

Teaching Methods

The teaching is provided through theoretical (T), theoretical-practical (TP) and pratical (PL) lectues. In the T lectures are exposed theoretical concepts and methodologies in the study of problems, together with some application examples. In TP classes the students must solve problems for applying concepts learned in the lectures, including more complex problems related to the design of the equipments. In PL sessions are performed two laboratorial works.

Learning Outcomes

Sensitize students to the pollution of water associated with industrial activity and the problems of water use; provide students with knowledge of qualitative and quantitative characterization of physical, chemical and biological pollutants; provide knowledge on the theoretical foundations of the main physical-chemical operations for the treatment of wastewaters; provide the necessary tools for sizing and selection of equipments.

Develop the following skills: the theoretical knowledge, capacity for analysis and synthesis; ability to integrate knowledge to solve practical problems.

Syllabus

1. Introduction. Water pollution. Water use.

2. Characterization of wastewaters. Types of sampling and storage of samples. Physical characteristics (solids content, smell, temperature, turbidity, and color) and chemical characteristics: organic matter (BOD and COD, etc.) and inorganic matter  (chloride, alkalinity, nitrogen, phosphorus, sulfur, cyanide and heavy metals).

3. Legislation.

4. Introduction to treatment processes: classification, removal efficiencies, selection and evaluation of the processes.

5. Grid systems and equalization.

6. Gravitational sedimentation: interaction solid / fluid, grit chambers and decanters. Flotation. Neutralization of alkaline and acidic effluents. Chemical precipitation, coagulation and flocculation.

7. Adsorption and ion exchange: isothermal equilibrium and saturation curves. Membrane-based processes: ultrafiltration and reverse osmosis.

8. Public water supply. Methods for water disinfection.
