Water Droplet System by Ingeenium
The water recovery product related to the incoming water flow ranges from 15% to 50% for most osmosis systems, while for the Modutech WDS system, it is 100%. In other words, for every 100 liters of seawater, from 15 to 50 liters of pure water would be produced with saltwater containing dissolved solids, or 100 liters in the case of WDS systems.
The WDS system reduces the overall energy consumption to 2300 kWh/AF, improving by around 30% the best available process. In addition to the electricity requirements, MSF, MED, and some VC plants also use thermal energy for heating the feedwater. (Due to the inefficiency of converting thermal energy into electricity, there is a high energy "penalty" if electric energy is used to heat the feedwater.) Comparison between distillation and reverse osmosis technologies An advantage of distillation plants is that there is a greater possibility of economies of scale. Distillation plants also do not shut down a portion of their operations for cleaning or replacing equipment as often as RO plants, although distillation plants can and have shut down for bundle replacement and cleaning. Pre-treatment requirements are higher for RO plants because coagulants are needed to settle particles before the water passes through the membranes. Unlike RO plants, distillation plants do not generate pre-treatment filter backwash wastes. Advantages of RO plants over distillation include: RO plant feedwater generally does not require heating, so the impact of thermal discharges is lower; RO plants have fewer corrosion problems; RO plants usually have lower energy requirements; RO plants tend to have higher recovery rates-about 45% for seawater; the RO process can remove unwanted contaminants such as trihalomethane precursors, pesticides, and bacteria; and RO plants occupy less space than distillation plants for the same amount of water production.
The "Water Droplet System" desalination system designed and built by Modutech is an innovative system that integrates the latest technologies to eliminate bacteria with a low enthalpy purification system for physically splitting sodium chloride from the water molecule. The system is designed to work in tandem with a photovoltaic field that allows the purification and disinfection of water with zero CO2 emissions while ensuring the use of sodium and chlorine valley of the process in order to eliminate the problem of releasing salts into seawater, creating high concentrations of salt and consequently generating a series of problems of closed and open water chemical composition.
The system then allows working virtually without electricity and is perfectly suited to create the structural bases to start building urbanization in areas with scarce availability of water and energy resources, typical of islands without springs or desert areas near the sea. The cycle can realize an integrated process that transforms into nitrogenous bases fertilizer without recovery of nitrates and the integration with human and animal waste and is therefore perfectly suited to the principle of "terraforming" desert areas in the presence of livestock even with high impact.
