New trends and future prospects for small capacity systems of Renewable Energy-driven DESalination (REDES) are reviewed assessed in this paper over a nominal desalination range 3–1000 m3/d. A thorough literature review is reported order to evaluate current research developing activities. Outstanding commercial the near identified two off-grid REDES technologies under development. First, wave en...

Solar-powered nodes employed in farmland wireless sensor network have energy advantages but at the same time have the problem of high cost. Wireless sensor network employs both solar-powered nodes and battery powered nodes which can reduce cost and prolong network lifetime. This paper presents an algorithm based on LEACH to study the clustering process of farmland environment monitoring sensor ...

This paper presents some aspects of forward osmosis coupled with reverse osmosis using a recirculating draw solution, to produce desalinated water or for dewatering/concentrating a feed stream, with some data provided from a number of operational sites. Many of these aspects are applicable to other osmotic processes and provide an insight into where they may be appropriately considered. A compa...

The chemicals and materials used to manufacture and package semiconductors and printed circuit boards are called electronic chemicals. The purity of these electronic chemicals, given by the industry association Semiconductor Equipment and Materials International (SEMI), is a very compromising concern for the semiconductor industrial sector, so very strict requirements are set to avoid microelec...

The potential for lithium-ion (Li-ion) batteries and supercapacitors (SCs) to overcome long-term (one day) short-term (a few minutes) solar irradiance fluctuations with high-temporal-resolution s) on a photovoltaic-powered reverse osmosis membrane (PV-membrane) system was investigated. Experiments were conducted using synthetic brackish water (5-g/L sodium chloride) varied battery capacities (1...

Model-based control and monitoring such as feed-forward/feedback control, fault detection and isolation (FDI), and fault-tolerant control (FTC) techniques that utilize Lyapunov-based control laws are implemented on a high recovery reverse osmosis desalination plant model. A detailed mathematical model of a high recovery reverse osmosis plant is developed. This model incorporates the large spati...

Liquid desiccant air conditioning (LDAC) is an emerging technology able to maintain optimal growing conditions in self-sustained greenhouses powered by solar energy. However, the regeneration of liquid (LD) a bottleneck LDAC. This study investigates six desalination technologies – membrane distillation (MD), reverse osmosis (RO), nanofiltration (NF), forward (FO), thermoresponsive (TR) solution...

A mathematical model of Reverse Osmosis membranes is proposed for use in the testing and comparison of control strategies in Reverse Osmosis plants. The model has been developed so that it can be used within off-the-shelf software and the parameters are simple to obtain from available plant measurements. Some simulations of the proposed model show that it correctly reproduces the expected proce...

Reverse osmosis (RO) is being increasingly utilized throughout the world for desalination due to the latest improvements in RO membrane performance and its reduced cost compared to thermal desalination. In this paper, Different media and chemicals have been used for Iron removal to prevent membrane fouling of groundwater reverse osmosis plant located in Shupramant-Giza. The objective is to pres...
