Electrocoagulation 101

Posted by Alex Barshai on Jun 7, 2017 11:57:07 AM

Electrocoagulation (EC) is an electrolytic process that is used mostly for wastewater and industrial process water treatment. Due to its unique ability to remove contaminants such as emulsified oils, suspended solids and dissolved metals, electrocoagulation has become one of the fastest growing technologies in this area. There are various devices and systems that comprise the basic principle of electrocoagulation which I would like to explain in this article.

10 Questions Answered About Electrowinning and Electrorefining

Posted by Alex Barshai on Apr 17, 2017 9:33:41 AM

1. What is electrowinning?

Electrowinning is a process in which metal ions present in an electrically conductive solution are separated using a direct current. This is achieved when a direct current is applied across an anode and cathode that are submerged in an electrically conductive solution causing the metal to deposit on the cathode. We say that metals like these were electrowon.

3 Methods of Nonferrous Metal Recycling

Posted by Alex Barshai on Apr 10, 2017 2:37:54 PM

In a world which is increasingly demanding sustainability, nonferrous metal recycling has become a very important practice. Opting for recycling does not only mean being responsible towards the environment and reducing the carbon footprint, it is also a very reasonable business in industries that rely on using non-renewable resources.

Copper Mined vs Copper Refined (by Country)

Posted by Alex Barshai on Dec 21, 2016 11:20:54 AM

Taking a closer look at worldwide copper production statistics we found that some of the biggest copper producing countries do not necessarily refine the copper at home. The reasons for this depend on various factors. We wanted to find out how much of copper is not actually refined in the same countries from which it was mined.

Video of emew Lab Cell Test

Posted by Alex Barshai on Dec 9, 2016 3:35:02 PM

Lab tests such as this are an ideal way to demonstrate the recovery capabilities of emew for a variety of electrolytes and feed materials. In most cases, these tests can be done right at your site so you can see the results for yourself.

This particular test is to demonstrate the recovery of copper cathode from a copper sulphate feed solution.  We can test a range of feed materials to recover not only copper, but also silver, nickel, tin and others.  This copper sulphate solution was prepared ahead of time and roughly 3L transferred to the feed tank.

5 Amazing Environmental Restorations

Posted by Alex Barshai on Oct 24, 2016 12:28:53 PM
Pollution has become a part of our daily lives. Everywhere we go we are exposed to various types of pollution such as noise, air, energy, light, and others. Pollution can be the result of natural source, as well as human-made. The leading cause of pollution is considered to be motor vehicle emissions. However, it is closely followed by chemical plants, coal-powered power plants, oil refineries, nuclear waste, farms, metal and plastic production, and other heavy industry. Today I wanted to talk about 5 amazing environmental restorations or polluted locations that were efficiently cleaned up by local governments.
