	Objectives
	•KNOWLEDGE AND UNDERSTANDING ACQUISITION OF BASIC KNOWLEDGE OF THE OPERATING PRINCIPLES OF WASTEWATER TREATMENT PLANTS AND OF THE DIFFERENT PHYSICAL, CHEMICAL AND BIOLOGICAL PROCESSES INVOLVED IN THE WASTEWATER AND SLUDGE TREATMENT CYCLES. •APPLYING KNOWLEDGE AND UNDERSTANDING ACQUISITION OF THE KNOWLEDGES AND UNDERSTANDING REQUIRED FOR THE DESIGN AND SCALING OF THE DIFFERENT PROCESSES GENERALLY USED IN THE WASTEWATER TREATMENT PLANTS. •MAKING JUDGEMENTS TO BE ABLE TO IDENTIFY THE MOST SUITABLE PROCESSES FOR THE WASTEWATER TREATMENTS •COMMUNICATION SKILLS TO BE ABLE TO ORALLY EXPLAIN IN A SYNTHETIC WAY A SPECIFIC TOPIC TREATED WITHIN THE LECTURES •LEARNING SKILLS TO BE ABLE TO APPLY THE ACQUIRED KNOWLEDGES TO PROBLEMS BEING DIFFERENT THAN THOSE SEEN DURING THE LECTURES, AND TO IMPROVE THE ACQUIRED KNOWLEDGE USING REFERENCES DIFFERENT FROM THE ONES GIVEN BY THE LECTURER

•KNOWLEDGE AND UNDERSTANDING
ACQUISITION OF BASIC KNOWLEDGE OF THE OPERATING PRINCIPLES OF WASTEWATER TREATMENT PLANTS AND OF THE DIFFERENT PHYSICAL, CHEMICAL AND BIOLOGICAL PROCESSES INVOLVED IN THE WASTEWATER AND SLUDGE TREATMENT CYCLES.

	Verification of learning
	THE ACHIEVEMENT OF THE COURSE OBJECTIVES WILL BE CERTIFICATED THROUGH THE SUCCESSFUL COMPLETION OF AN EXAMINATION WITH A GRADE EXPRESSED IN THIRTIETHS. THE EXAMANIATION WILL INCLUDE BOTH WRITING AND ORAL TESTS. THE STUDENT IS REQUIRED TO PASS FIRST A WRITING-TEST CONTAINING MULTIPLE-CHOICE AND OPEN QUESTIONS AS WELL AS SMALL EXERCISES RELATED TO THE TEACHING PROGRAM TOPICS AND TO THE TECHNICAL VISITS OF THE DEPURATION PLANTS. A MINIMUM GRADE OF 18/30 IS REQUIRED FOR THE WRITING TEST WHICH SHOULD NORMALLY TAKE AT LEAST 60 MINUTES AND IT AIMS TO VERIFY THE ABILITY OF THE STUDENT TO CORRECTLY APPLY THE THEORICAL KNOWLEDGE AS WELL AS HIS CAPACITY TO UNDERSTAND THE PROBLEMS BEING FACED. THE ORAL TEST WILL CONSIST IN AN INTERVIEW WITH QUESTIONS AND DISCUSSION ON BOTH THE THEORETICAL AND PRACTICAL CONTENTS OF THE COURSE PROGRAM IN ORDER TO ASSESS THE LEVEL OF KNOWLEDGE AND UNDERSTANDING OF THE STUDENT, TO VERIFY HIS COMUNICATION SKILLS. THE FINAL GRADE IS OBTAINED FROM THE MEAN OF BOTH GRADE TESTS AND THE FINAL MINIMUM GRADE FOR THE SUCCESSFUL COMPLETION OF THE EXAMINATION IS 18/30. THE MINIMUM GRADE (18) IS AWARDED WHEN THE STUDENT DEMONSTRATES A LIMITED KNOWLEDGE OF THE ITALIAN LEGISLATION DEDICATED TO THE PROTECTION OF WATER, OF THE OPERATION OF URBAN WASTE WATER TREATMENT PLANTS AND OF THE PRINCIPLES OF OPERATION OF TYPICAL PROCESSES PRESENT IN THE PLANTS. THE MAXIMUM GRADE (30) IS AWARDED WHEN THE STUDENT DEMONSTRATES A COMPLETE AND IN-DEPTH KNOWLEDGE OF THE ITALIAN LEGISLATION ON WATER PROTECTION, THE OPERATION OF URBAN WASTE WATER TREATMENT PLANTS, OF THE TYPICAL PROCESSES PRESENT ON THE WATER LINE AND ON THE SLUDGE LINE OF THE PLANTS AND A KNOWLEDGE OF THE CRITERIA USED FOR THE SIZING/DESIGN OF THE SINGLE PROCESSES. HONOURS (LODE) MAY BE AWARDED TO STUDENTS WHO REACH A MAXIMUM MARK OF 30/30 AND WHO DEMONSTRATE THAT THEY ARE ABLE TO APPLY INDEPENDENTLY KNOWLEDGE AND SKILLS ACQUIRED IN CONTEXTS OTHER THAN THOSE PROPOSED IN CLASS.
