Yes, the level of total dissolved solids in water can affect chlorine disinfection. Higher levels of total dissolved solids can interfere with the effectiveness of chlorine disinfection, as the solids can react with chlorine and reduce its ability to kill pathogens. It is important to monitor and manage total dissolved solids levels to ensure adequate disinfection.

total dissolved solids is how much of the solid is dissolved in the liquid, while suspended total suspended solids is the amount of the solid floating in the liquid. e.g. if you had a solution with both and you filtered the solution then evaporated out the liquid, the solids that you filtered out would be the suspended solids, and the the solids remaining after evaporating the liquid out would be the disolved solids.

The Fixed Solids is the term applied to the residue of any one of the following Total Solids, Total Suspended Solids, or Total Dissolved Solids after igniting at 500 ± 50ºC

The meaning of TDS is total dissolved solids.
