Desalination of historic mansonry: Pre-investigation, treatment and follow-up care

Salt crystallization constitutes one of the most widespread decay mechanisms affecting historic buildings. Desalination is a conservation treatment of growing importance in the case of historic masonry. Salts present in porous materials cause damage through their interaction with moisture. Consequently, in certain situations the prevention of...

Design of an Energy Recovery Concept for a Small-scale Renewable-driven Reverse Osmosis Desalination System

The desalination industry has grown exponentially the last four decades as countries seek solutions to water scarcity caused by population growth, climate change, pollution and industrial development. All source water types included, reverse osmosis is the prevalent desalination process, accounting for more than half of the global capacity. The...

Evaluation of the potential of renewable driven desalination systems in Greece: A functional analysis and a financial feasibility study in the case of Sifnos Island

Water shortage is a major problem affecting certain areas of the planet. Almost 15% of the world’s population has not access to clean water and water demand is expected to double in the next twenty years. Over the past few years, a shift towards renewable energy technologies is observed. Rising energy prices, fossil fuel scarcity and increasing...

A PV Powered BWRO Desalination Installation with Energy Recovery and Hydro-Pneumatic Energy Storage

This MSc. Thesis project was performed at the Sanitary Engineering Department of the TU Delft as part of the Sustainable Energy Technology program. It is one of the unique research projects performed in the field of renewable driven Reverse Osmosis desalination, producing fresh water with only renewable energy sources as driving force. With the...

Mild desalination of cooling tower blowdown water with electrodialysis and membrane capacitive deionization: A comparative study

Study towards the feasibility of desalination of cooling tower blowdown water with electrodialysis and membrane capacitive deionization.

Upflow limestone contactor for soft and desalinated water

Desalinated or demineralised water or even soft water is characteristically low in hardness, alkalinity and pH. Thus, these kinds of water need to be re-conditioned (re-mineralized) before distributing for usage as drinking water. The produced water is expected to satisfy the following requirements: safe quality for human health, no quality...

Design and Characterization of a single-effect Electrohydrodynamic Desalinator

World water scarcity has forced the public and private initiative to consider the sea as a possible source of drinking water over the last decades. The pressure was felt by the scientific community which started investigations for cheap and efficient ways to treat sea water. Nowadays, a number of well proven technologies exist with advantages...

Fine tuning of desalination poultices: Try-outs in practice

Towards a design for an improved drinking water supply system on Bonaire, St Eustatius and Saba

In 2008, the author has conducted a research study on behalf of the Caribbean Water Association on the consequences of the constitutional change of the Netherlands Antilles for the drinking water supply on Bonaire, St Eustatius and Saba (BES). This research study formed the basis for further research in the form of this MSc. thesis. Being the...

Development of an environmental impact assessment and decision support system for seawater desalination plants

Seawater desalination is a rapidly growing coastal-based industry. The combined production capacity of all seawater desalination plants worldwide has increased by 30% over the last two years: from 28 million cubic meters per day in 2007—which is the equivalent of the average discharge of the River Seine at Paris—to more than 36 million cubic...

Reuse of softening pellet for remineralizing desalinated water

Desalinated water produced by reverse osmosis can generally be characterized as aggressive and corrosive water due to its low pH, low bicarbonate concentration and low hardness. Post treatment is required to remineralize desalinated water to comply with the Drinking Water Guidelines. Softening pellets, a “waste” product from the pellet softening...

Menging bij een twee-lagen-systeem veroorzaakt door wind

Electrokinetic salt removal from porous building materials using ion exchange membranes

The removal of salt from porous building materials under the influence of an applied voltage gradient normally results in high pH gradients due to the formation of protons and hydroxyl ions at the electrodes. The formed acidic and alkaline regions not only lead to disintegration of the porous material, but also affect the salt transport. In this...
