CONDUCTIVITY α TDS
highest value: GT as it due to hand-soap; toothpaste; oil-grease and ect
The level of this graph dropped progressively in C-shaped tank, reaching tap water values similar to Cs4 indicating that the treatment system namely the subsurface flow and the C-shaped tanks are effective in removing TDS. However it increases the level in pond as due to excess waste and food from fish and also air pollution such as SO2,CO2NO can contribute to TDS increase.
