Most industrial and manufacturing processes, whatever the industry sector, tend to use good quality or even purified water in one or more of their stages. Despite it being such a commonly used resource, there are a lot of misconceptions about how we reuse water which could have a major impact on how effective our processes are, both from a cost and environmental perspective. Read on to find out about the most common misconceptions surrounding the use and reuse of water in manufacturing processes, and what we can do about them.
The term membrane technology is used to describe a variety of liquid filtration and separation processes that includes micro-filtration, ultra-filtration, nano-filtration and reverse osmosis. All these filtration processes have one thing in common – the use of a membrane as a major component in the separation process itself.
Typically speaking you will find a membrane used in technologies that filter water from various sources to get rid of any particulates (contaminants) in that water.
The purification of seawater can be achieved in a number of ways. Desalination is one of them and it involves extracting salts and minerals from saline, salt or seawater. It is a water treatment purification process that is used extensively around the World and its use is increasing as population growth, industrialisation and climate change impact the demands for clean water suitable for drinking purposes.
Salt water is commonly desalinated in order to produce purified water that is suitable for humans to drink (potable water) or use for the irrigation of crops. When salt water is desalinated it produces fresh water with salt as a by-product.
Reverse osmosis, often abbreviated to RO is a purification procedure that uses membrane technologies to filter and purify liquids. Reverse osmosis is now commonly used around the world for the treatment and purification of water used for drinking (potable water) and industrial processes.
Reverse osmosis makes use of a semipermeable membrane to separate unwanted materials found in the raw water (solute). These materials can include salts and minerals, bacteria and other contaminants.
