The Ultimate Guide to Wastewater Treatment

Posted by Alex Barshai on Aug 21, 2018 11:18:13 AM
Clean, fresh water is a luxury in many countries and is increasingly becoming a valuable commodity.  Our society today is faced with the challenge of harnessing the power of advanced wastewater treatment technologies to preserve our precious water resources.  Not only does this apply to municipal water treatment plants that work around the clock to make sure communities all over the world have access to clean, fresh water, but also in industrial processes to minimize usage and waste.
 
"Presently only 20% of globally produced wastewater receives proper treatment."
- United Nations Educational, Scientific, and Cultural Organization (UNESCO)
 
In the years following the industrial revolution and continuing on into the information age, industries have been challenged to develop new and innovative ways to treat wastewater and bleed streams to encourage recycling and reduce discharge towards the holy grail of so-called 'zero discharge'.  We've come a long way in the latter part of the 20th Century, but there's still work to be done as populations swell, economies grow and everyone strives to improve their quality of life and that of his or her children.

FAQ: emew VS Conventional Electrowinning

Posted by Sara Wollschlaeger on Jul 30, 2018 2:30:39 PM

In one of the previous posts I described the basic principle of conventional electrowinning. Today I would like to talk about the differences between conventional electrowinning and proprietary emew technology, which is based on fundamental electrowinning tenets but offers so many additional benefits.

Acid Mist

Posted by Sara Wollschlaeger on Jul 23, 2018 3:53:37 PM

Many industries generate acid mist as a result of their industrial processes. In most cases the acid mist will be caused by usage of inorganic acids, and in particular sulfuric acid. Sulfuric acid is mostly used in a production of fertilizers, and industries like pulp and paper, iron and steel, mining, refining and wastewater treatment.  Acid mist is formed as a condensation of acid vapour and the extent of the mist will depend on the industry, process and solution itself.

Prices of emew revealed: How much does a 600 t/a electrowinning plant cost?

Posted by Trevor Bergfeldt on May 15, 2018 8:55:04 AM

One of the most important and frequently asked questions we get is “How much does an emew plant cost”? The cost obviously depends on the size of the emew plant, so to answer this question we need to know how many electrowinning cells are required, which depends on several factors.

 

In this blog, I will discuss some of the key factors we take into consideration when sizing an emew electrowinning plant and provide some examples for three different applications.
