Abstract

Laboratory experiments were carried out at Faculty of Agriculture,
Ain Shams University, Shoubra El-Khaima, Qalubia Governorate, Egypt
to calculate discharge of emitters and sprays, chemical and mechanical
analysis of treated wastewater and irrigation water.
Field experiments were carried out at Eastown and Lake View sites
located in the Fifth Settlement - New Cairo, Egypt. The area under
investigation was 600 m², divided into two sections: spray irrigation system
and drip irrigation system. Irrigation with two types of water: treated
wastewater and irrigation water with the use of two types of filters in the
Lake View site (a screen filter and a sandy filter) and the use of one type
of filters in the Eastown site, which is screen filter. The washing process
was carried out manually and automatically.
This study aimed to:
• Studying the effect of irrigation systems by using irrigation water and
treated wastewater on the clogging of emitters.
• Determine the best efficiency of filters, emission uniformity for drip
system and distribution uniformity for spray system, in Lake View and
Eastown sites under using irrigation water and treated wastewater.
• Comparing between irrigation water and treated wastewater on turf
quality index (color – density and ground cover %) for lawn plant
(paspalum 10).
The obtained results were follows:
• Emission uniformity for drip system was higher when using automatic
operation with treated wastewater by (5 - 6 - 2.3 - 4.9%) for on-line and
built-in emitters in Lake View site, on-line and built-in emitters in
Eastown site, respectively, than manual operation.
• Distribution uniformity for spray system was higher when using automatic operation with treated wastewater by (5 and 5.1%) in Lake View
site and Eastown site, respectively, than manual operation.
• Clogging ratio by using manual operation with treated wastewater was
(40 – 48 - 34.5 - 44.7%) for on-line and built-in emitters in Lake View
site, on-line and built-in emitters in Eastown site, respectively.
Clogging ratio using automatic operation was (20 – 25 -18.75 - 22%)
for on-line and built-in emitters in Lake View site, on-line and built-in
emitters in Eastown site, respectively.
• The turf quality index (color, density, ground cover) gave the highest
degree when using treated wastewater with automatic operation, which
is due to the nutrients found in treated wastewater.
It is recommended to:
• It is preferable to use media filters before the screen filters with treated
wastewater to reduce the ratio of clogging with impurities instead of
using only screen filters. Especially in the case of lower processing
degrees.
• It is preferable to use the automatic washing system (in the automatic
pressurized irrigation system) because it gives higher efficiency than
manual washing. Especially in the resorts, in the case of high treatment
degrees.
• In general, the quality of wastewater reused through modern
pressurized irrigation systems must be taken into consideration in
terms of all its natural, chemical and biological characteristics,
viscosity and degree of treatment when using the modern pressurized
irrigation system to choose the appropriate filters according to the
filtering capacity, the type of media and sprays or drippers.
• A good management program and scheduling of the irrigation system
should be established in case of reuse of treated wastewater in particular
and in case of reuse of any water quality in general. (Turbid water -
agricultural drainage - sewage - industrial drainage).
