Conjunctive use of coffee effluent and pond water on the performance of robusta coffee and soil properties
A field experiment was conducted to study the influence of coffee effluent irrigation on performance of established robusta coffee, nutrient contribution and microbial activities in the soil. The results revealed that the field irrigated with coffee effluent from aerobic tank having COD of 1009 ppm, did not affect the yield of clean coffee (1309 kg ha-1) and it was on par with the plots irrigated ...

Utilization of artificial recharged effluent for irrigation: pollutants' removal and risk assessment
The reclaimed water from soil aquifer treatment (SAT) column was reused for irrigation as the source water, pollutants' removal and health risk assessment was analyzed via the comparison with secondary and tertiary effluents. The effect of the SAT pre-treatment on the qualities and growth of different crops (Lachca sativa – lettuce, Brasica rapa var chinensis – pak choi, Cucumis sativus – ...

Disposal of De-Icing Effluents By Irrigation
At Zurich Airport (Switzerland) alcohols, as well as urea in small quantities, are utilized for de-icing in order to maintain the air traffic during winter. To purify the accumulated de-icing effluents a new, groundbreaking, cost-effective (investment and maintenance) method was developed which has been successfully applied since winter 2000/2001. The de-icing effluents are irrigated onto the ...

Effect of irrigation with anaerobic baffled reactor effluent on Swiss chard (Beta vulgaris cicla.) yield, nutrient uptake and leaching
The disposal of treated wastewater from an anaerobic baffled reactor (ABR) effluent into water bodies can cause pollution. Treated wastewater management through irrigation of crops has the potential of increasing crop production through nutrient uptake while reducing the risks of environmental pollution. However, this study aimed to investigate the effect of irrigation with ABR effluent on ...

A strategy for sustainable livestock husbandry wastewater treatment in China
A strategy for sustainable treatment of the livestock husbandry wastewater is proposed, which is to recycle anaerobic treatment effluent as irrigation water. The existing treatment system was modified by deleting the treatment units after the anaerobic digestion. Chinese cabbage and Korean radish were selected as seeding plants in two sets of field irrigation experiments with various portions of ...

Impact assessment of pre- and post-sown irrigation with Post Methanation distillery Effluent on soil health and crop yield
Field experiments were conducted to assess the optimum dilution of Post Methanation distillery Effluent (PME) to utilise as an organic nutrient source for growing rice and wheat crops. Dilution levels of distillery effluent significantly affected the biomass production as well as grain yield of rice and wheat crops. Levels of organic carbon and NPK were significantly higher in effluent treated ...

Reuse of constructed wetland effluents for irrigation of energy crops
The aim of this study was to evaluate biomass production of promising ‘no-food’ energy crops, Vetiveria zizanoides (L.) Nash, Miscanthus × giganteus Greef et Deu. and Arundo donax (L.), irrigated with low quality water at different evapotranspiration restitutions. Two horizontal subsurface flow (H-SSF) constructed wetland (CW) beds, with different operation life (12 and 6 ...

Minimizing health risks during secondary effluent application via subsurface drip irrigation
Health risks posed on consumers due to the use of agricultural products irrigated with reclaimed wastewater were assessed by numerical simulation. The analysis is based on defining of an Exposure Model (EM) which takes into account several parameters: (i) the quality of the applied wastewater, (ii) the irrigation method, (iii) the elapsed times between irrigation, harvest, and product ...

Subsurface Drip Irrigation of Omaha Golf Course Fairways with Treated Effluent
ABSTRACT In 1999, in addition to the existing 825 lots developed in the 1970’s, a new 600-lot subdivision was commenced at Omaha Beach. Omaha Beach is a popular recreation beach community north of Auckland. In conjunction with the new residential development the existing 9-hole golf course was expanded to a full 18-hole course. The existing wastewater treatment and disposal infrastructure ...

Intake and digestibility of ‘Coastal’ bermudagrass hay from treated swine waste using subsurface drip irrigation
Waste handling systems for confined swine production in the upper South (approximately 32–37° N and 79–93° W) depend mainly on anaerobic lagoons and application of the waste effluent to cropland. The main objective of this study was to evaluate the quality of ‘Coastal’ bermudagrass [Cynodon dactylon (L.) Pers.] hay receiving effluent generated from a raw swine waste treatment system designed to ...

Biomass Production of Arundo Donax: A Country Specific Overview
With around 50-80 dry tonnes of biomass yield per hectare every year, Arundo donax (giant reed) is way ahead of its competitors. Of course, this yield depends on climate and applied agricultural technology. In this article below, the studies carried out concerning the biomass yield and economics of Arundo donax are presented. Biomass production in the Mediterranean: Italy, Spain and Sicily ...

Corn Irrigation System
From Seed to Harvest: The Role of Corn Irrigation System Today we’re going to dive deep into the world of agriculture, focusing specifically on corn irrigation system. From the moment a corn seed is planted to the time it’s ready for harvest, irrigation plays a vital role. This process ensures that the crops get the right amount of water at the right time, which can significantly ...

Effect of irrigation with secondary treated effluent on essential oil, antioxidant activity, and phenolic compounds in oregano and rosemary
Shortage of water throughout the world dictates utilization of marginal water for irrigation. Treated urban wastewater is a common alternative water source for irrigation in arid and semiarid regions. In this study we aimed to evaluate the effect of irrigation with secondary-treated effluent on plant development, essential oil yield, antioxidant activity and selected antioxidant phenolic ...

EDTA in the environment: with special reference to the dairy industry
Ethylenediaminetetraacetic (EDTA) acid has been used as an additive to caustic agents facilitating removal of Ca, Mg and trace metals in dairy processing plants for many years. Effluents from the dairy industry are either discharged to surface waters or used in land irrigation systems. In particular, the effluents from a large dairy factory discharged to a small stream have the potential to pose ...

Seasonal ammonia losses from spray-irrigation with secondary-treated recycled water
This work examines ammonia volatilization associated with agricultural irrigation employing recycled water. Effluent from a secondary wastewater treatment plant was applied using a center pivot irrigation system on a 12 ha agricultural site in Palmdale, California. Irrigation water was captured in shallow pans and ammonia concentrations were quantified in four seasonal events. The average ammonia ...

Irrigating with reclaimed water through permanent subsurface drip irrigation systems
ABSTRACT In Hawaii, reclaimed water has been used in agricultural irrigation and the irrigation of golf courses and other large landscaped areas. However, the Hawaii Department of Health's new "Guidelines for the Treatment and Use of Reclaimed Water" published in November 1993, limits uses of reclaimed water through overhead sprinkler irrigation systems. The subsurface drip irrigation concept ...
