Triton - Model Type 306 SSVI - Reader Brochure

The SSVIr Reader determines sludge settling rate and gives an indication of turbidity and also mixed liquor suspended solids (MLSS). It is made to fit with the standard SSVI measuring equipment – Type 305. The SSVIr operates by passing an infra red beam through the settlement column. The amount of infra red light absorbed by the sludge is related to the solid content. Hence, the settled sludge will absorb significantly more light than the clear supernatant showing the sludge height. The sludge height is plotted against time, from this data it is possible to determine the settling rate as well as SSVI.
