UTVÄRDERING AV HUSHÅLLSMIKROVÅGSUGN FÖR TORKNING AV PROVER VID BESTÄMNING AV SUSPENDERADE ÄMNEN OCH TORRSUBSTANS, Evaluation of a Household Microwave Oven for Drying Suspended Solids and Total Solids Samples
Drying of suspended solids and total solids samples using a household microwave oven is satisfactory for experimental work as well as a standby method for normal operational sample analysis. Results agree with analysis made using a conventional oven for influent and effluent waters, mixed liquor suspended solids, recycle solids and primary, thickened and dewatered sludges. More samples can be analyzed quicker when experimenting. Microwave drying of solids samples should be used with caution when the sample deviates from normal conditions.
