- 2. To measure the total suspended solids, volatile suspended solids & turbidity To identify the relationship between turbidity &total suspended solids To discuss the relationship between TSS & DO level released into the water To identify the effect of TSS level on living things in the water
- 3. Water quality parameter that is defined as the quantity of material suspended in a known volume of water that is trappable in a filter. TOTAL SUSPENDED SOLID VOLATILE SUSPENDED SOLID The portion of the suspended solids which are volatilized at 550℃. PHYSICAL PARAMETERS Physical characteristics of water are determined by senses of touch, sight, smell and taste. For example temperature by touch, colour, floating debris, turbidity and suspended solids by sight, and taste and odor by smell.
- 4. TOTAL SUSPENDED SOLIDS Block the light from penetrating through the water, thus slow down the photosynthesis process Less dissolved oxygen to be released into the water by plant and eventually the plant will die Dissolved oxygen levels decreases because the bacteria will used up the dissolved oxygen to decompose the plant. H I G H T S S V A L U E SLOW PHOTO -SYNTHESIS PROCESS PLANT DECOMPOSED
- 5. VOLATILE SUSPENDED SOLID Importance of VSS Great importance in water and wastewater treatment. Give rough approximation on organic matter present in water Better indicator of amount of bacteria in water
- 6. High TSS value lead to high turbidity Water appeared cloudy and murky Less light penetration Water is not safe to be consume
- 7. The microfiber filter paper was weighed. The pre-weighed filter paper was placed into the filter holder with the wrinkle surface up. The filter holder was placed assembly in the 250 ml filter flask and the filter paper was wet with deionized water to ensure adhesion to the holder. 50 ml of well mixed water sample was transferred to the filtering apparatus while applying vacuum followed by washing 10 ml deionized water. The filter paper was dried at the oven for 60 minutes at 103̊C- 105̊C. The filter was taken out of the oven and allowed to cool to room temperature. The filter was weighed using analytical balance.
- 8. The aluminium dish was weighed using analytical balance. The filter from step 7 of TSS was transferred to pre-weighed aluminium dish. The dish with filter was weighed using analytical balance. The aluminium dish was placed in muffle furnace at 550̊C for 30 minutes. The dish was taken out from the furnace and cooled in desiccators. The dish was weighed using analytical balance.
