TITLE

VOLATILE SUSPENDED SOLIDS

INTRODUCTION Volatile solids are the material lost after ignition at 550oC and those that remain as residue is called Fixed solids. The determination of VSS is useful in control operation of wastewater treatment plant operation because it offers a general rough approximation of the amount of organic matter present in the wastewater, activated sludge, and industrial wastes.

PREAMBLE

OBJECTIVES 1. To determine the concentration of volatile solids and fixed solids in water samples. 2. To analyze the data and interpret the results of VSS experiment. LEARNING OUTCOMES At the end of the laboratory activities, students would be able: 1. To acquire and develop sublime psychomotor skills in conducting laboratory experiments. 2. To work as a team, demonstrate leadership and enhance communication skills through discussion.

PROBLEM STATEMENT

PROBLEM STATEMENT The quality of surface waters is easily deteriorated by various human activities. A water sample taken from Sg. Klang is to be examined. You are required to conduct Volatile Suspended Solid test and identify both organic and inorganic matters in the water sample by using the appropriate apparatus in environmental laboratory. APPARATUS Analytical balance, desiccators, aluminium dishes, muffle furnace

WAYS AND MEANS

PROCEDURES 1. Weight the aluminium dish to the nearest 0.1g. 2. Mix the sample and add the sample to the aluminium dish. 3. Place the sample in a preheated oven and evaporate at 103105 °C for approximately 6 hours. 4. Take the dish out of the oven and allow it to cool to room

Weight the dish to the nearest 0.1g using the analytical balance . 6. Transfer the dish into preheated muffle furnace at 550 °C for 30 minutes then take the dish out with thongs and let it cool to room temperature in desiccator. 7. Weight the dish to the nearest 0.1g and repeat ignition until 2 successive samples weighing do not differ by more than 4% or 0.05g, which ever less. 8. The loss of weight is the total volatile solids. Weighted residue is total fixed solids. 9. Calculation:

A = weight (mg) of solids + dish before igni tion B = weight (mg) of solids + dish after ignition C = weight (mg) of dish

DATA ANALYSIS All data collected and observed during the test must be tabulated in proper format for easy verification and presentation of the technical report

RESULTS

RESULTS, ANALYSIS AND CONCLUSION Each group is required to submit a technical report of the laboratory results highlighting the apparatus used, the procedures undertaken for the test, data acquisition process, analysis carried out and the relevancy of the set-out output to address the given problem. The format of the technical report can be done according to the creativity and the discretion of the group members. The report must be submitted within SEVEN (7) days after the completion of the test....
