Renewable energy

The potential for an autonomous wave-powered desalination system is considered and it is identified that the most promising configuration is a reverse osmosis (RO) plant utilising a pressure exchanger-intensifier for energy recovery. A numerical model of the RO plant with a pressure exchanger-intens

In electrical installation and building services engineering the power factor is a major consideration in efficient building or system operation. It is the measure of how effectively your equipment is converting electric current from power generation network to useful power output. Your industry can

A new desalination technology named Desalination Pipeline is proposed. The Desalination Pipeline system enables simultaneously desalination and efficient transport of distilled water by applying the working principle of a heat pipe without its liquid recirculation function. The energy source for the

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

Operation of an experimental RO plant connected directly to a wind system without energy storage was studied. The data obtained confirm the wide spectrum of operation of the plant with respect to the power available and the operation of the system. The development of an RO plant for variable charges

The development of small-scale stand-alone desalination systems is important to communities on islands and in isolated inland areas. In such places, electricity supplies are often expensive and unreliable, while the wind resource is abundant. The system presented here comprises a 2.2 kW wind turbine

A small-scale seawater reverse-osmosis system with excellent energy efficiency is presented. The system promises to deliver up to 460 l/h of potable water, from seawater (at 40,000 ppm), while consuming less than 1600 W of electrical power. This represents a specific energy consumption of less than

The Italian Ministry of Public Works has funded a study aimed at assessing the technical feasibility and financial viability of a disalination plant to be implemented in Agrigento, Sicily. The plant, with a design production capacity of 40,000 m3 and an estimated cost of € 120 million, will serve 19

The phenomenon referred to as waterhammer can be used to create the pressure required for reverse osmosis of seawater, this has been described in a previous paper [1]. A subsequent paper then investigated economic feasibility and concluded that it could achieve significant cost savings as well as el

This paper presents the development of a new process to desalinate seawater using solar energy. By the proposed process, the solar energy heats airflow up to a temperature between 50 and 80°C. The moderate solar heated air will be humidified by injecting seawater into the air stream. Later on, the w
