One of the great challenges facing humanity is the availability of water in sufficient quantity and quality to meet needs. In addition, such availability must be environmentally and economically sustainable. Continued population growth, pollution, and climate change make it even more difficult to achieve this challenge.
Thus, if the goal is to develop and implement sustainable, environmental, and economic methods to provide water with the necessary quality for all people, it will be imperative to make use of all tools available. There are many measures of different natures that must be considered and include, not only technological, but also educational and political ones. Some of them are:
- Water demand control: Implementation of saving systems/devices in homes, agriculture, industries, new industrial production methods with reduced water consumption, control of water leaks in distribution systems, etc.
- Water production: Desalinization and desalination methods, rain and fog harvest, potabilization, etc.
- Wastewater treatment and reuse: Grey water segregation, wastewater treatment methods such as membrane methods and advanced oxidation techniques, natural treatment systems such as ponds and constructed wetlands, evaluation of benefits and threats of using treated wastewater in agriculture, sludge reuse alternatives, etc.
The objective of this Special Issue is to give an idea of the state-of-the-art of development and implementation of the different technological, educational, and political methods, and initiatives aimed at achieving sustainable water management around the world.

Title: Performance of Flocculation Titanium Salts for Seawater Reverse Osmosis Pre-Treatment

Abstract: Membrane founding is one of the biggest issues in seawater reverse osmosis (RO) desalination which leads to major decline in the flux as well as increase overall operation and maintenance cost. As such suitable pre-treatment is required to reduce membrane fouling. In this regards, this study evaluated the performance of titanium tetrachloride (TiCl4) and titanium sulphate (Ti(SO4)2) as coagulant in actual seawater to remove organic matters and solids. The performance was studied in terms of turbidity, dissolved organic carbon (DOC), humics rin terms of UV-254 and zeta potential at different coagulant doses and solution pH. The two Ti based coagulants were compared with commonly used ferric chloride (FeCl3) coagulant in desalination plants. The results showed that at pH of 8.0 (similar to seawater pH), TiCl4 had advantages over FeCl3 and Ti(SO4)2 at the same coagulant dose of 20 mg/L. Under this condition, TiCl4 achieved ~70% DOC and UV-254 removal. This was approximately two times higher than FeCl3 and Ti(SO4)2. Nevertheless, FeCl3 and Ti(SO4)2 showed better turbidity removal. The differences in the performance of the coagulants were associated with the coagulant mechanisms based on the floc zeta potential evaluation. The coagulant mechanisms of Ti-salts could be associated to charge neutralization while FeCl3was inclined towards adsorption mechanism.
