Summary of Method
This method of determining suspended solids is a simple, direct
measurement which does not require the filtration or ignition and
weighing steps that gravimetric procedures do. The USEPA
specifies the gravimetric method for solids determinations, while
this method is often used for checking in-plant processes.
