Modular desalting for specialized applications

In this paper, we consider the uses of modular containerized desalination f acilities in both emergency and temporary applications in remote and popula ted areas. These types of systems, while not new to the marketplace, are ra pidly gaining prominence for numerous system designs by those wishing rapid deployment of complete units. With the considerations of the military and emergency management organizations forming some paramount reasons for this section of the industry, these sea or land transportable system designs are also highly useful for the temporary needs of the construction industry. T he need for purified water for construction personnel as well as building m aterial support may seem unrealistic, but the rise in projects in remote ar eas or areas without existing water supplies has given credence to these de signs. These all-inclusive self-contained units can be quickly and economic ally erected on various types of sites, with only a water source and availa ble power necessary for their function. Various designs and their implement ation will be discussed, with modular pre-treatment and post-treatment opti ons examined. Also, the modular approach to larger scale facilities will be addressed. Storage and transfer modules to contain and distribute the prod uct of these systems will be featured as well. The usage of sophisticated c ontrol systems with modem capability, both cellular and land based, will be referred to in systems designed for use in remote areas. These systems mig ht include a modular power generation unit as well as the water treatment m odules to allow for a complete, stand alone system. Also, a design proposal for systems capable of handling many different qualities of feed water wil l be presented as a "universal" modular system. This type of system could b e installed in any location, regardless of the feed water quality, and func tion to provide potable water for a shortterm situation.
