ENVIRONMENTAL LAB;WATER CONSTITUENTS
1. PURPOSE
The purpose of this experiment is to clarify and categorize the separation techniques used to
identify and denote the different types of solids in waste water and water in general. The
techniques include evaporation, filtration, combustion and weighing. The experiment wuill
also appreciate the fact that various solids are defined by the materials and the methodologies
applied in their determination.
2. PROCEDURE
Total Solids
The evaporating dish was ignited and cooled in the desiccators until a constant weight was
attained. 50 ML of the original solution was put in the dish and allowed to evaporate to
dryness. The residue was dried at 103C for 1 hour. The desiccators were then cooled and
reweighed again.
Suspended Solids
A filter paper was put and 50 ml was spilled. The filter paper was then removed along
with tweezers and dried at 103 C for 1 hour. The desiccators were cooled and reweighed
again.
Dissolved Solids
We treated the filtrate of suspended solids determination as for total solids determination.
