There are three main types of volcano-composite or strato, shield and dome. Composite Volcanoes. Composite volcanoes, sometimes known as strato volcanoes, are steep sided cones formed from layers of ash and [lava] flows.The eruptions from these volcanoes may be a pyroclastic flow rather than a flow of lava.A pyroclastic flow is a superheated mixture of hot steam, ash, rock and dust.omposite volcanoes, sometimes known as strato volcanoes, are steep sided cones formed from layers of ash and [lava] flows.

Desalination plants typically use reverse osmosis, a process that pushes saltwater through a membrane to create purified, drinking water. But in addition to being costly, and energy-intensive, reverse osmosis can negatively impact the environment.
Refrigerant Dehumidifier / Desiccant with Pre-Cooling. Desiccant Dehumidifier A desiccant dehumidifier operates on a totally different principle to a refrigerant type. The main benefit of a desiccant dehumidifier is that it performs exceptionally well when used in cooler climates, or when a low dewpoint is required.s air passes through these channels, moisture is transferred between the air and the desiccant in its vapour form. The rotor is generally divided into two air zones which are separated by seals, the process sector (typically 75%), and the reactivation sector (typically 25%).
