Desalination

The paper, “Heat pumps as a source of heat energy for desalination of seawater”, was published in Desalination [Vol. 139, 2001]. In the paper, heat pumps using agent R12 or water and vapor were introduced to be used as a source of heat energy for desalination. The cyclic processes of heat pump were

A numerical study has been carried out to investigate the transient thermal performance of a naturally circulated humidifying/dehumidifiying solar still. A comparison of forced circulation performance and the influence of different environmental, design, and operational parameters on the still produ

A patented cycle for water desalination and power generation was evaluated with regard to thermal efficiency and water production. The inventor of the patent claimed that the patented cycle provides a thermal efficiency of 41%, which is higher than current combined water and power generation steam p

A project is under development at Padre Island and Mustang Island, Corpus Christi, Texas, combining desalination of brackish groundwater with ASR storage of treated drinking water, both utilizing brackish, confined sand aquifers and clay confining layers at depths of less than 250 m. The combination

The objective of this paper is to present the planned activities and future results of the ADIRA project. After a short introduction into the problem of energy and clean water supply in rural areas, a detailed project description follows in order to inform relevant stakeholders about the present act

In this work, we report about cellulose acetate nanofiltration (NF) membrane preparation according to the phase inversion process. Pore size was monitored by using dope solutions of two polymer concentrations (20 and 22 wt-%) and annealing temperatures from 60–80°C. Membrane characterization include

Horizontal-tube falling film condensers are used in many fields: chemical industries, refrigeration, desalination, cooling, etc. However, their performances cannot be predicted precisely due to the complexity of the phenomena. In this paper, heat and mass transfer in a horizontal-tube falling-film c

The present work investigated the separation properties through monovalent-ion-permselective membranes (Neosepta CMX-S, ACS) in electrodialysis. An experimental study for desalting single electrolytes, binary and ternary mixtures, was carried out. Results showed that divalent-ion rejection takes pla

Multi-stage flash (MSF) and reverse osmosis (RO) are the most common techniques for seawater desalination. A significant difference between these methodologies consists of their different energy requirements, i.e., thermal energy for MSF and mechanical energy for RO plants. The presence of both desa

a process flow sheet and a plan view are given. A preliminary study on further R&D actions and possible measures to enhance plant economy are also discussed.
