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.

Can I recover copper from this? Copper recovery from the ground up

Posted by Trevor Bergfeldt on Oct 19, 2017 9:45:13 AM

A question that we hear from Clients every day is "Can I recover (copper - or other metals) from this?"  The material in question can be concentrated wastes, dilute effluents, ores, concentrates, residues, plating baths, bleed streams and so on.  It seems like a very easy and straightforward question to answer, and in some cases that is true.  In other cases, however, the answer is a bit more complicated requiring some additional information.  Let's take a closer look at the good, the bad, and the ugly when it comes to the common question "Can I recover (copper - or other metals) from this?"

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.

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.

3 Ways Wastewater Treatment Plants Can Make You Rich

Posted by Alex Barshai on Jul 18, 2016 4:41:31 PM

 

Billions of litres of wastewater are treated every year in wastewater treatment plants around the world. This wastewater, both industrial and municipal, can contain various pollutants depending on the source. Wastewater may contain soap, waste products, food scraps, human waste, oils and in some cases, metals. The main goal of wastewater treatment is to preserve the environment and keep the pollutants out of rivers and oceans.

Metal Finishing: What's Electrowinning got to do with it?

Posted by Dora Ip on May 18, 2016 10:00:00 AM

What is Metal Finishing?

Metal finishing is a type of surface finishing that can be defined as the deposition of a metallic coating onto a product either to enhance performance, function or aesthetic qualities while providing overall added value. While it's not obvious on a daily basis, many objects have been subjected to metal finishing for use in our normal lives. These include parts in a car, aircraft, fencing, medical and dental devices, industrial machinery or even beautiful pieces of art. The term finishing is based on the fact that it's normally the last step of the manufacturing process (save for any heat treatment).
