Experimental Objectives:
The objective of the experiment was to determine the number of suspended solids in a given wastewater sample using the given stipulations.
Experimental Theory:
The quality of water is very essential in human’s daily life. In the determination of water quality, suspended solids are measurement and an indicator that can be used. Suspended solids are materials that do not dissolve in water and are referred to as being non-filterable in nature. The ss is the residue upon which evaporation based on the non-filterable sample on filter paper. Additionally, dissolved gases, organic constituents, and minerals can produce aesthetically displeasing odor, color, and taste. Suspended solids usually exclude light hence lowering the growth of oxygen-producing plants. In polluter waters, the determination of SS is extremely valuable. Also, the parameters for suspended solids are used while one is measuring effluent and wastewater influent quality. Increment in dish weight shows the total dissolved solids. A well-mixed sample has to be filtered through a weighed standard glass fiber filter, as well as the residue be retained on a dried filter to a constant weight at a specific temperature. Turbidity is water’s cloudiness because of suspended solids that are present. The total suspended weight is, therefore, the increase in weight of the filter. In case the suspended materials clog the filter and extend filtration. Thus, the difference between total dissolved solids and the total solids might provide an estimation of totals suspended solids.

Experimental Methods
Filtration apparatus were placed together with the weighed filter within the filter flask. The sample was mixed well as poured to a graduated cylinder to a selected volume. Suction to the filter flask was applied with a small amount of distilled water. Next, the volume selected was poured into the filtration apparatus. The next step was drawing the sample via the filter to the filter flask. Next, the graduated cylinder was rinsed to filtration apparatus with three successive ml portions of provided distilled water, allowing for full drainage between the rinsing.
Additionally, the suction was continued after the filtration of the final rinsing was completed. Lastly, the filter was dried in an oven at a temperature of 103 -105 for at least one hour. The filter was cooled within a desiccator but at room temperature. After cooling, the filter was then weighed.
Results:
GF/C filter before filtration: 0.09 g
GF/C filter after filtration and drying: 0.103g
Filtered sample: 5 ml
Weight = (0.103g – 0.09) = 0.013g
Converting the weight of residue in mg (the weight (g) is multiplied with 1000)
= w(mg) = 0.013g x 1000
= 13gmg
Total suspended solids (mg/l)
V = volume of the sample (ml) (converting ml to L, through multiplying by 1000)
= 13mg/5ml = 2.6 mg/mL
= 2.6 mg/mL x 1000 ml/L = 2600mg/L
=2600mg/L
Discussion:
In the provided sample, the total suspended solid was to 2600mg/L. Therefore, the suspended solids were the most responsible for turbidity. The objective of the experiment was to determine the amount of suspended solids using the provided wastewater sample. The sample of the water supplied contained the various number of suspended solids as it was turbid as well as brown color. The quantitative examination of suspended solids within the sample was done whereby, a well-mixed sample was then filtered via a weighed fiberglass filer paper. Moreover, the increased weight of filter paper showed suspended solids in the sample as the filter paper’s pore size was not large enough to permit anything. Water flow through the pores, and the entire suspended solids stayed on the surface of filter paper. Suspended solids will affect physical parameters, like chemical and turbidity, such as dissolved oxygen. The SS contributes to blocks of sewer pipes. They are essential as pathogens and pollutants are done based on the particle’s surface. The smaller the particle’s size, the higher the total surface area per mass unit of that particle; hence high pollutant load likely to be carried. In the experiment, I learned on how specifically to test the quality of water using chemical as well as parameters of water. Besides, water quality might not necessarily be determined using a parameter. It is not enough to ensuring that if the water is not or polluted, hence a variety of instruments should be used in stabilizing the results.
Conclusion
To conclude, I achieved the experimental objective. Theoretical total solid-based o inlet can be higher compared to the outlet from the plant’s same treatment process. Suspending large particles vi water motion might produce large values of suspended solids that are not relating to turbidity increment. Particles that are above a particular size are not necessarily measured through turbidity bench meter, although they contribute substantially to the suspended solid value.
