Technologies for Water Extraction and Use in Agroindustry
Objectives
At the end of the curricular unit the student will be able to:
- Identify and characterize alternative sources of water supply for agroindustry.
- Use methods for the determination of capitation, consumption and discharge.
- Know the laws of general hydraulic applied to flow in open channels and in porous media.
- Identify the components of water adduction, abstraction and distribution systems.
- Quantify water and irrigation requirements.
- Know the main irrigation and drainage systems.
Know the physical, chemical, and biological processes applied in the treatment and reuse of clean effluents.

Teaching method
Lectures. Oral presentations and resolution of exercises. Work field. Observation of water well construction.
Technical visits to irrigation, drainage, water reuse and wastewater treatment systems.
Evaluation method
Continuous evaluation: 3 tests (exams to do during the course) with an overall average result of 9.5 values.
Final exam: In case of failure in the continuous evaluation, the student can take the final exam after classes, during the exam period.
