Sludge Thermal Drying and Cogeneration

The need to seek how to finally dispose of the bio-solids generated in the sewage treatment plants has led to a process of thermal drying consisting of heat application for evaporation of a major part of the interstitial water content of these bio-solids from sewage plants.Through this process, by reducing the volume, a better final disposal of sludge generated is obtained, moreover, in many cases, it may be used as fertilizer to improve ground ...

Drinking Water

Drinking Water Plants turn natural or raw water into drinking water. These installations are located among the water collection installations (reservoirs and wells) and the tanks and pipes networks delivering water to households. Their mission is to eliminate the three main types of undesirable substances in the water intended for human consumption: mineral material, organic material (phenols, hydrocarbons, detergents, pesticide waste ...) and ...

Desalination

Desalination is a process that separates most of the salts dissolved in a saline solution. There are several different techniques used to this aim, however the most extended one is Reverse Osmosis desalination. High pressure water is pumped through semi-permeable membranes that separate water and salts. The energetic efficiency in the desalination process has developed significantly in the last years rendering Reverser Osmosis the best alternative. ...
