in an arid country like kuwait with harsh and hot climate conditions, the scarcity of fresh water supplies presents a serious threat to sustainable socio-economic development and growth. kuwait is an oil rich country with capital abundance and coastal locations enabled it to build desalination plants for fresh water production that is sold to the customers at highly subsidized prices. however, ...

The purpose of the research was to study the effect of microwave power inpretreatment of fresh waterhyacinth on biogas production. The variations of microwave power levels are 240; 400; 560 and 800 W. The variations of microwave heating time are 5; 7 and 9 min. The unpretreated fresh water hyacinth are used as control. The result of research showed that the microwave pretreatment of fresh water...

This paper presents sizing, energy management strategy, and cost analysis for a configuration consisting of solar photovoltaic (PV) panels, fuel cell (FC) storage system, and reverse osmosis (RO) desalination technology for combined power and fresh water production. In this system, PV is the main power supply source; fuel cell is a storage system accompanied by Hydrogen production and storage d...

• A new hybrid humidification–dehumidification and air conditioning system is proposed and investigated. • The proposed system keeps the function of the air conditioning system and uses it in water desalination. • The effects of system operating parameters on system performance were evaluated and correlated. a b s t r a c t a r t i c l e i n f o An experimental study of the performance of a hyb...

Microalgae are simple chlorophyll containing organisms, they have high photosynthetic efficiency and can synthesize and accumulate large quantities of carbohydrate biomass. They can be cultivated in fresh water, seawater and wastewater. They have been used as feedstock for producing biodiesel, bioethanol and biogas. The production of these biofuels can be integrated with CO2 mitigation, wastewa...

Water is a prerequisite for life on our planet. Due to climate change and pollution, water availability for agricultural production, industry and households is increasingly put at risk. With agriculture being the largest water user as well as polluter worldwide, we estimate anthropogenic nitrogen and phosphorus emissions to fresh water related to global crop production at a spatial resolution l...

abstract the irrigation water quality is not suitable for crop production in most regions of iran. it is estimated that almost six bcm/year of saline water enter to the rivers, in iran. the saline water can potentially use for growing of tolerant crops with a specific management on the agriculture practice. one of the management methods is the conjunction use of fresh and saline water. in this ...
