What is the correct temperature range for drying total suspended solids (TSS) samples?

The correct temperature range for drying total suspended solids (TSS) samples is 103-105°C. This specific range is used to ensure that the total suspended solids are dried sufficiently without overheating, which could lead to loss of volatile components or changes in the chemical composition of the solids, affecting the accuracy of the results.

Maintaining this temperature range allows for consistent drying conditions, which is crucial for achieving reproducible results in laboratory analyses. At temperatures below 103°C, there may be insufficient drying, leading to residual moisture that inaccurately increases the weight measurement of the suspended solids. In contrast, temperatures above 105°C could result in decomposition of some of the solids, particularly organic materials, which could skew the results in terms of the mass measured.

Understanding the importance of this temperature range is vital for ensuring that the TSS measurements are both accurate and reliable for wastewater treatment assessments.
