WAST07005 2013 WASTEWATER TREATMENT LABORATORY
This practical Module covers methods used for analysis and monitoring chemical, physical and microbiological parameters of wastewater treatment processes. Students work in teams and each team is responsible for the maintenance, operation and monitoring the efficiency of treatment of a laboratory-scale wastewater treatment system based on the activated sludge process.
On completion of this module the learner will/should be able to;
Understand the operation of a secondary wastewater treatment process and be able to list the various parts of the treatment plant and their functions
Work independently and in groups, safely, to carry out a range of analytical laboratory procedures related to the wastewater treatment process to include microbiological and chemical/physical methods as appropriate.
Conduct the various analytical methods for monitoring the operation of a secondary wastewater treatment plant in a competent manner
Complete calculations regarding the design and operation of a wastewater treatment plant
Maintain detailed records of laboratory activities.
Collate, summarise and present overall results on a data base and in a report
Check compliance with the relevant regulations covering wastewater treatment.
Module Assessment Strategies
Laboratory skills and report-writing ability are assessed as part of the practical work performed during the module. Use of electronic spreadsheet in a timely manner and maintaining Labatory Record Book in order to assess thier record keepnig ability. Presentation of laboratory acquired data in groups to assess their team work and presentaion skills.
Maintenance and operation of wastewater treatment process. Conduct the following analyses: BOD, COD, Suspended Solids, MLSS, MLVSS, SV, SVI, ammonia, nitrate, orthophosphate, coagulation, floccuation, microbiological examination of activated sludges, denitrification, sludge respiration rate, sludge solids content.
