Table 1 lists the common ions and organic compound that might exist in the water sample, also it includes the Dissolved Oxygen test to show the health of the water sample. Table 2 shows the secondary data of the pool water that after the treatments which contains Distillation and Filtration. By comparing the primary data and secondary data to analysis the water sample.
As shown in Table 1, for the common cations, except for the Lead ion that all the others common cations are unpresented. For the common anions, only Chloride is presented which is caused by disinfectant (HClO). The concentration of Nitrate Nitrogen is 9.99 mg/L in the test water, and there are no Nitrite Nitrogen and Ammonia presented. Testing the dissolved water contains DO test and BOD5 test. The difference between DO test and BOD5 test is 2 mg/L is less than 4 mg/L. Generally, if …show more content…
By using hardness titration to find out the concentration of calcium ions in the water sample is 10.02 mg/L and magnesium ions is 6.08 mg/L (Refer to Table 1). Hard water have values of over 100 mg/L, thus it can be inferred that the water sample is soft water which is below 100 mg/L.
After doing the basic testing on the water sample, the water sample was treated by distillation and filtration. Through the treatments on the water sample, distilled water and titrated water were produced and both of the products was compared to the primary data.
As shown in Table 1, the total chloride and bromine content has decreased from 2.0 to 0.2 and 4.5 to 0.4 after being treated via distillation and filtration. From the change of the data, it can be seemed that two ways of treatments can remove chloride and bromine ions effectively. During the process of distillation, the chloride and bromine ions would be remained in the water sample. Likewise, during the process of filtration, the activated carbon can absorb the chloride and bromine ions in the water
