The present study was executed in the Laboratory of Laser Applications in Agricultural Engineering at the National Institute of Laser Enhanced Science (NILES) at Cairo University to obtain the peak of optical properties at transmission and absorption intensities of irrigation water samples which carried out at the National Irrigation Laboratory of Agricultural Engineering Research Institute (AEnRI), ARC, Dokki, Giza. The main objectives of the present work are to create a selection of suitable wavelength to study the optical properties of suspended solids in filters and determination of concentration suspended solids in the filtration media. In the drip irrigation system, the small openings can be easily clogged by suspended solids according to the level of TSS and plugging is caused fall into three categories (<50, 50-100, >100) (Slight, Moderate, Severe) respectively. Light was measured via remote sensing reflectance (Rrs) spectra deduced from radiance and irradiance measurements that were performed using an Ocean Optics USB650 to detect suitable wavelengths from visible and invisible light (ultraviolet, visible and infrared wavelengths) to measure the peak of optical properties at reflection, transmission and absorption. It was found that using a media filter of Local basalt media increased TSS in a water sample and created filter pressure differential results. It increased from 0.2 bar to 0.6 bar and also increased absorption (0.189 to 0.447a.u.). Reflection and transmission decreased (79.285 to 49.645a.u.), (78.288 to 44.711a.u.).
