PARTICLE FILTRATION FOR WASTEWATER IRRIGATION

The filterability properties of secondary effluents used for irrigation was studied. It was found that filterability of wastewater effluents can effectively be evaluated using particle size distribution measurements by the following methods: calculation of removal ratios of different particle sizes for different design variables; computation of particle volume distribution according to particle size ranges; and determination of the beta factor value from the power law distribution function. This value, when larger than 3.0, suggests lower filtration efficiency. More than 90% of the particles in the reservoir effluents within the range detected were smaller than 10 mu m; these particles constituted a large part of the total solids volume. These and other study findings are discussed.
