The mathematical model to predict the performance and the exergetic efficiency in a multi-effect desalination system with thermal vapor compression (MED-TVC system) has been presented. The energy and the concentration conservation law were developed for each effect, considering the boiling point elevation and the various thermodynamic losses by developing the mathematical models. These analyses...

The escalating freshwater demand is stimulating the researchers to optimize performance of desalination technologies. current study presents exergoeconomic optimization a forward feed multi-effect (FF-MED) system under two configurations i.e., conventional MED and with energy recovery (MED-ER). A detailed numerical model concerning energy, exergy, component-based analysis employed estimate cons...

Humidification-dehumidification desalination (HDD) systems offer a feasible approach for the production of fresh water in inaccessible areas as they can be operational using renewable energy and require little maintenance. Various studies are being carried out to boost system performance. In this paper, an open air HDD is proposed that exploits enhanced evaporation condensation processes by imp...

Abstract Humidification–dehumidification desalination (HDH) is one of the suitable methods for saline and brackish water in a small scale. In this research, an HDH method with direct contact dehumidifier has been analyzed theoretically experimentally. The setup consists two similar packing towers humidification dehumidification, 10 inches diameter, which are filled up to 1 m Rushing packing. ne...

This article applies nonlinear programming techniques to optimize humidification-dehumidification (HD) desalination cycles for operating conditions that result in maximum gained output ratio (GOR). Closed air open water as well as open air open water cycles, each with either an air or a water heater, were considered in this analysis. Numerical optimization resulted in a substantial increase in ...

Gastro-oesophageal reflux (GOR) disease may cause excessive crying in infants. The role of GOR was evaluated in infant irritability and an attempt was made to define clinical predictors of pathological reflux. Seventy consecutively admitted infants with irritability and presumptive GOR were retrospectively reviewed. All had undergone prolonged oesophageal pH monitoring. Pathological GOR was def...

The scarcity of drinkable water supplies is becoming a serious and troubling challenge to long-term development. This issue emphasises the urgency implementing rapid desalination options. However, capital-intensive process that requires significant amount energy, since it now mostly powered by fossil fuels across globe, has potential leave carbon footprint. In this light, transitioning green en...

A higher frequency (25%) of gastrooesophageal reflux (GOR) has been previously reported in patients over 5 years old with cystic fibrosis compared with controls without cystic fibrosis. It was believed that GOR was caused by the complications of cystic fibrosis. We looked for GOR in all 26 children younger than 60 months who had cystic fibrosis diagnosed. They had a classical genetic profile an...

An integrated membrane distillation (MD) flowsheet, consisting of direct contact (DCMD) and vacuum (VMD) units, was proposed analysed in terms thermal performance water recovery factor, for the first time. The same lab-scale module (40 cm2) used carrying out experiments DCMD VMD at fixed feed operating conditions (deionised 230 L/h ~40 °C) while working permeate side with deionised 18 °C a 20 m...

Adsorption-based desalination (AD) is an emerging concept to co-generate distilled fresh water and cooling applications. The present study aimed provide a comprehensive review of the adsorption systems subsequent hybridization with known conventional cycles such as multiple-effect AD (MED), solar regenerable, integrated evaporator-condenser cascaded, ejector systems. are investigated for energy...
