Abstract
The performance of four filtration systems (sand, screen, disc and a combination
of screen and disc) and six emitter types (four pressure compensated and two
non-pressure compensated), using secondary and tertiary effluents from a
wastewater treatment plant, was studied for 1000 h. Only sand filtration
significantly reduced turbidity and suspended solids. The best emission
uniformity was obtained by the emitters placed after the sand filter and the
screen filter with the secondary and tertiary effluent, respectively. On the other
hand, emitters that operated with disc filters showed the worst emission
uniformity for both effluents. Emitter type P2 was the only one achieving values
of emission uniformity higher than 90% with all filtration systems and effluents
except the screen filter and the tertiary effluent.
Keywords: wastewater, drip irrigation, filtration, clogging.
1 Introduction
The use of effluents in agriculture is a viable alternative in areas where water is
scarce or there is strong competition for its use. The best way to apply effluents,
from public health and environmental points of view, is micro-irrigation [1]. The
main problem when using effluents in drip irrigation systems is emitter clogging
[2] because the reduction of emitted flow affects water distribution and,
