چکیده

In order to assessment of SDI system application in the condition of wastewater reuse, three treatments with three replications were design. These treatments included check treatment with drinking water (CH), surface drip irrigation with wastewater (DI) and subsurface drip irrigation with wastewater (SDI). In addition, before pipeline, a SDI filtration designed to improve biological index of wastewater. The results of this research showed that the BOD5, TSS and nitrogen component decreased during filtration acceptably. But the microbiological factors didn’t improve completely. In this condition, injection of wastewater below the soil surface (SDI system) could decrease the surface microbiological pollution significantly as compare to CH. In concluded the SDI system recommended in the wastewater reuse condition and application of new system of drilling considered for installing, monitoring and maintenance of SDI.

Design Considerations for Subsurface Drip Irrigation (SDI) Systems

Gary A. Clark Research Irrigation Engineer Quick Facts Subsurface drip irrigation (SDI) is a low-pressure irrigation system that uses polyethylene driplines that are permanently buried below the soil surface. Water drips to the surrounding soil through built-in emitters (specialized small openings). SDI places water directly into the root zone of the crop. It may improve yield due to high appli...

Bioenergy from Coastal bermudagrass receiving subsurface drip irrigation with advance-treated swine wastewater.

Coastal bermudagrass (Cynodon dactylon L.) may be a potentially important source of bio-based energy in the southern US due to its vast acreage. It is often produced as part of a waste management plan with varying nutrient composition and energy characteristics on fields irrigated with livestock wastewater. The objective of this study was to determine the effect of subsurface drip irrigation wi...
