Determination of the Relationship between Water Turbidity (NTU) and Total Suspended solids (TSS) in drip irrigation

Sand filters are composed of sand-filled containers with determined granulation and specified thicknesses of pressurized sand layers that work under pressure and they are placed in the center control system after the cyclone and before the grid or disk filter. The aim of this study was to determine the relationship between water turbidity and Total suspended solids (TSS). To determine the samples turbidity, they were tested using a spectrophotometer and the percentage of light passing was obtained through each sample separately. The test of determining total suspended solids was also performed. The results of this experiment showed that there is a quadratic equation between the percentage of light passing and total suspended solids, which is presented as the main equation from figure 3, that is more correlated with the data. As can be seen, at 450 nm, there is a higher correlation between the turbidity and the light transmittance and less error.
