Introduction:
Solid matter present in potable, natural, and industrial waters may harm existence of organisms. Material, apart
from the water contained in liquid portion, is classified as solid matter. Waters with high dissolved solids usually
are of lesser palatability and may provoke an adverse physiological reaction in the transient consumer. Water high
in suspended solids may be aesthetically unacceptable for such purposes as bathing. So, Solids analyses are vital in
the control of biological and physical wastewater treatment processes and for assessing fulfillment with regulatory
organization in wastewater effluent limits.
Gravimetric analysis is a method of determining sample mass, involving three general analytical operations in
addition to weighing, namely filtration, evaporation, and combustion. Filtration is process of taking apart
“suspended” and “particulate” fractions from “dissolved” and “soluble” fractions. Filters can be divided into two
categories – pore filters and depth filers. Evaporation separates water from material dissolved or suspended in it.
The methodical purpose of combustion in solids determinations is to differentiate between organic and inorganic
matter. Organic matter will be destroyed completely by burning at 550°C for 30 minutes (David & Vernon).
The typical definition of solids refers to the matter that remains as residue upon evaporation and drying at 103 to
105°C. There are different types of solids in the water, such as - dissolved solids, suspended, volatile, settleable
and fixed. Solids can be classified in the following (APHA, 1995):
Total Solids: It is material residue left in the vessel after evaporation of a sample solution and its consequent drying
in an oven at 103 – 105 °C. Total Solids includes total suspended solids [total solids retained by a filter], and total
dissolved solids [total solids passes through the filter of 2.0 μm (or smaller) nominal pore size under specified
conditions.]
Fixed solids: Residue of total, suspended, or dissolved solids after heating to dryness for a specific time at a
particular temperature. The weight loss on ignition is called volatile...
