Global regulation changes demand reduction of the emissions from power plants.
Flue gas desulfurization (FGD) is a set of technologies used to remove sulfur dioxide (SO2) from exhaust flue gases of fossil-fuel power plants, as well as from the emissions of other sulfur oxide emitting processes. When using a wet FGD scrubbing process, wastewater is generated, which must be treated before disposal
FGD wastewater contains high concentrations of sulfates, calcium, magnesium, heavy metals, TSS and ammonia.
Stricter regulations in Europe, China, USA and other countries require Zero Liquid Discharge (ZLD) treatment for the wastewater.

Utilizing Available Coldness from Liquefied Natural Gas LNG Regasification Process for Seawater Desalination
In this article a case study was considered, in which an LNG regasification plant can supply 1750 ton/hr of water-glycol solution at -15°C to be utilized for seawater desalination. The main challenge in this evaluation is being able to provide a desalination solution able to compete with the commonly used RO plants.

Three Pressure Retarded Osmosis PRO Processes
Pressure retarded osmosis (PRO) can be implemented on a number of water types, using different technologies and achieving various power outcomes. This paper presents the three most practical options.
Implementation of Build Operate Transfer Schemes: Obstacles and Solutions
This paper focuses on these cases, addressing the main causes of the failure of suggested/initiated BOT scheme offerings and what prevented their successful implementation. The paper analyses the main constraints and obstacles characterizing these setbacks, and presents different solutions and alternatives to by-pass and/or overcome these obstacles that, if adopted, could enhance the possibilities of successful implementation of the projects.
Steam Driven Large Multi Effect MVC (SD MVC) Desalination Process for Lower Energy Consumption and Desalination Costs
This paper will also describe the thermodynamic advantages, the specific investment and desalination costs comparison, and the resulting desalination cost reduction potential of the steam-driven multi effect MVC process.
