Membrane water treatment is a process that removes unwanted constituents from water. A membrane is a barrier that allows certain substances to pass through while blocking others. Water treatment facilities use various types of membranes and processes to clean surface water, groundwater, and wastewater to produce water for industry and for drinking.
Water is one of the most important commodities that supports life on earth but very few understand how hard it is to get clean, potable freshwater. Water, in all its forms, covers three quarters of the Earth's surface. The water levels on Earth remain relatively the same each year. Every day, water goes through a cycle that sees it flow from land, to the seas and then evaporates into the atmosphere through the processes of evaporation and precipitation.

In conventional construction projects there are three main parties: the water treatment plant owner, the engineer, and the contractor. In specialized process projects a system supplier with particular expertise on the process is also usually involved. This party is also called an Original Equipment Manufacturer (OEM). For membrane treatment projects this entity is commonly called the Reverse Osmosis Equipment Manufacturer (ROEM) or the Membrane System Supplier (MSS). The ROEM or MSS may have a separate contract with the water treatment plant owner, or they may be a subcontractor to either the engineer or the main general contractor.
It has always been the Holy Grail of automobiles – the car that will run on water. What would it take to build such a car? Innovation, skill, experience, and an immense amount of knowledge about water systems. It will also take a very good hydrogen generator.
Membrane filtration can be explained as a method of allowing certain materials to permeate a surface while blocking others. For water, this means allowing clean water to flow through the membrane while eliminating sediments and other materials or pathogens. Membrane filtration is a multiple-step process which is considered to be one of the most cost-effective water treatments available.
Whether commercial or residential, the modern world is currently seeing an increase in water reclamation practices. Reclaimed water, perhaps better described as "recycled water," is wastewater that has been filtered and treated for reuse, thereby limiting the need for fresh water use. This practice has increased in popularity over recent years. GAO reported 36 states as using reclaimed water in 2013, compared to just 23 states in 2003.
