Water Monitoring

• Total Kjehdahl Nitrogen

The total Kjehdahl nitrogen in the sample is 0

• Total Suspended Solid

TSS  =  (Final weight - Initial weight)

              40 ml

                        = 0.0915 g - 0.0904 g

                   40 ml

     = 0.0011g

  40 ml

                   = 0.0000275 g/ml

• Total Dissolved Solid

TDS  =  (Final weight - Initial weight)

              30 ml

                        = 55.6212 g - 55.6079 g

                   30 ml

     = 0.0133g

  30 ml

                   = 0.0004433 g/ml

Results

Discussion

For week 2, compare to week 1, the result are slightly different. For biological oxygen demand (BOD), as for week 1 for specifically in dilution 25 ml the value 0.1633 mg/L but in week 2 the value decrease to 0.0508 mg/L. For dilution 50 ml the value 0.155 mg/L but in week 2 the value decrease to 0.125 mg/L but for dilution 100 ml the value 0.33 mg/L but in week 2 the value increase to 0.84 mg/L. According to the result of colour , there is a big difference between week 1 and week 2. On week 1, the value of colour measured was 224 Pt/Co but in week 2, the colour measured was 0.1 Pt/Co. It shown that the colour of Taman Tasek Tampin is unstable. For Turbidity , it also show a big different between week 1 and week 2. The value of turbidity in week 1 is 26.6 NTU and in week 2 the value is decrease to 0.30 NTU. While the result for conductivity quite different which is the value is increase from 67.1 µS in week 1 to 84.1 µS in week 2. The pH for week 1 and week 2 did not show so much different which in 7.18 in week 1 and 8.47 in week 2. For temperature are quite similar on both week which is 23.03˚C in week 1 and 23.30˚C in week 2. For total suspended solid show  some quite big gap which is on week 1 is 0.0001255 g/ml while in week 2 is 0.0000275 g/ml . For total dissolved solid also show some large different between both week. The value for week 1 is 0.025578 g/ml and the value decrease in week 2 to 0.0004433 g/ml. And last but not least, the value of total Kjeldahl Nitrogen is constant both week . The value is 0.
