Wastewater Engineering Laboratory ReportCircled numbers that have been written in the margin of your report correspond to the comments shown in Table 1.Table 1. List of Feedback CommentsCode Description1Do not use capital case to emphasise text. Use Larger font and/or bold.2Add page numbers at bottom of page3Aim is too long and detailed, write a general statement that summarises the purpose of this work, or it goal (what you want to achieve by doing the investigation).4Your Objectives do not describe adequately the “specific steps” in your investigation that were undertaken to achieve the goal defined by the Aim5Define the sample (s) you used, where they were from, sampling date, etc R = Raw sewage collected before primary treatment; S= Settled sewage taken just after primary treatment; F = Final effluent taken after the secondary treatment stage.6Give full details about the method, or add a reference (e.g. APHA XXX) that gives this detailed information. Currently there is insufficient information to know what was done.7Do not split a table over two pages, table title goes above table, and figure legends go below figures8Do not leave a section heading as the last line at the bottom of a page9Use Harvard referencing system for inserting references in the text (Author, date) , not the numerical Chicago style [3].10Convert concentration of NO3 and NO2 ions to the concentration of N contained within the ions as follows... (mg NO3/L) x 14/62 = NO3-N/L and (mg NO2/L) x 14/48= NO2-N/L11Convert PO4 to P as follows..... ( mg PO4 /L) x 31/95 = mg PO4-P/L12EPR 7.01 is an Environment Agency guidance document, the UWWT Regulations (1994) or UWWT Directive (1991) are the original legislation “Standards”, so better to cite one of these.13Solids 100 mg/L limit given in EPR 7.01 relates to Water treatment plant discharges, not Wastewater treatment plant effluent. Use UWWT Regulations (1991) value of 35 mg/L.14Which BOD and COD data should you use in calculations? Use the BOD sample dilutions thatgive “at least 2 mg/L DO drop” with “at least 1 mg/L DO remaining” after 5d. For COD use the sample volume that gives the most consumption of the dichromate (has smallest FAS titration), but still has detectable dichromate remaining (i.e. titration is more than zero).15Figure legend goes below the figure, Table title goes above the table. Remove all text that Excel may automatically place in the wrong position.16Label graph axes..... show units and the parameter name17Compare the removal efficiency (% removal) you observed with the typical removal that is expected from the primary treatment stage18Compare the removal efficiency (% removal) you observed with the typical removal that is expected from the secondary treatment stage19BOD incubation was for 3 or 4 days, and the BOD5 was estimated by calculation using the kinetics equation BODt = UBOD (1 – e-kt)20 Do not confuse the meaning of the word “Standard”. Use this word only when you mean a statutory (legally required) threshold level of a parameter that MUST be achieved. “Typical values” reported in text books are values or ranges that we tend to see for that parameter in
