What is ASTM D5907-13 and Why is it Important for Water Quality?
Water quality is a crucial factor for human health, environmental protection, and industrial applications. Water quality can be affected by various substances, such as dissolved solids, suspended solids, organic matter, metals, nutrients, pathogens, and more. To measure and monitor these substances, standardized test methods are needed.
One of the most widely used test methods for water quality is ASTM D5907-13, which covers the determination of filterable matter (total dissolved solids or TDS) and nonfilterable matter (total suspended solids or TSS) in drinking, surface, and saline waters, domestic and industrial wastes. These test methods are based on the principle of filtering a known volume of water sample through a pre-weighed filter, drying the filter and the residue, and weighing them again to calculate the mass of filterable and nonfilterable matter.

How to Perform ASTM D5907-13 Test Methods?
To perform ASTM D5907-13 test methods, you will need some equipment and materials, such as:
A balance with a sensitivity of 0.1 mg or better
A drying oven capable of maintaining a temperature of 103 2C
A desiccator with silica gel or other suitable desiccant
A filtration apparatus with a vacuum pump or aspirator
Filter holders that can accommodate filters with a diameter of 47 mm or larger Glass fiber filters with a pore size of 0.7 -|m or smaller
A graduated cylinder or volumetric flask with a capacity of at least 1 L
A stirring rod or magnetic stirrer
Reagent-grade water
Water samples to be tested
The test methods consist of two parts: Test Method A for filterable matter (TDS) and nonfilterable matter (TSS), mg/L; and Test Method B for total dissolved solids high precision method, -|g/g. The main steps for each test method are as follows:
Test Method A: Filterable Matter (TDS) and Nonfilterable Matter (TSS), mg/L Label and weigh a filter for each water sample to be tested.
Place the filter in a filter holder and connect it to the filtration apparatus. Measure a known volume of water sample (usually 1 L) using a graduated cylinder or volumetric flask.
Pour the water sample into the filter holder and apply vacuum to draw the sample through the filter.
Rinse the filter holder with three portions of reagent-grade water (10 mL each) to remove any remaining sample.
Transfer the filter with the residue to a labeled aluminum dish or petri dish. Dry the filter and the residue in an oven at 103 2C for at least one hour. Cool the filter and the residue in a desiccator for at least 30 minutes.
Weigh the filter and the residue and record the mass.
Calculate the mass of nonfilterable matter (TSS) by subtracting the mass of the filter from the mass of the filter and the residue.
Calculate the concentration of nonfilterable matter (TSS) in mg/L by dividing the mass of nonfilterable matter by the volume of water sample.
To determine the mass of filterable matter (TDS), place another labeled and weighed filter in a filter holder and connect it to the filtration apparatus.
Pour a known volume of water sample (usually 100 mL) into the filter holder and apply vacuum to draw the sample through the filter.
Rinse the filter with three portions of reagent-grade water (10 mL each) to remove any remaining sample.
Transfer the filtrate to a labeled aluminum dish or petri dish.
Evaporate the filtrate to dryness in an oven at 180 2C for at least one hour. Cool the dish and the residue in a desiccator for at least 30 minutes.
Weigh the dish and the residue and record the mass.
Calculate the mass of filterable matter (TDS) by subtracting
Test Method B: Total Dissolved Solids High Precision Method, -|g/g
Label and weigh a filter for each water sample to be tested.
Place the filter in a filter holder and connect it to the filtration apparatus. Measure a known volume of water sample (usually 100 mL) using a volumetric flask.
Pour the water sample into the filter holder and apply vacuum to draw the sample through the filter.
Rinse the filter with three portions of reagent-grade water (10 mL each) to remove any remaining sample.
Transfer the filtrate to a labeled aluminum dish or petri dish.
Evaporate the filtrate to dryness in an oven at 180 2C for at least one hour. Cool the dish and the residue in a desiccator for at least 30 minutes.
Weigh the dish and the residue and record the mass.
Calculate the mass of total dissolved solids (TDS) by subtracting the mass of the dish from the mass of the dish and the residue.
Calculate the concentration of total dissolved solids (TDS) in -|g/g by dividing the mass of total dissolved solids by the volume of water sample.
