Electrocoagulation is the in-thing for treating wastewater

Today, there is an urgent need to take care of the available natural resources, especially water. Industries are expanding at an alarming rate and populations are growing, but the same cannot be said about water, minerals and other natural resources. Recycling and treating wastewater is an efficient way of availing clean water for use in urban centres. Through electrocoagulation, you can redeem wastewater and make it usable in domestic and industrial settings.  The following is a detailed discussion about electrocoagulation to help you understand this water treatment technique:

What is Electrocoagulation?

Briefly, electrocoagulation (EC) refers to a wastewater treatment method that combines the removal of both solid and chemical contaminants in wastewater and industrial processed water. It involves discharging electrical current through wastewater to create charges and facilitate the separation of solid and chemical contaminants. Unlike many other techniques used for treating water, EC is more reliable because you don't need to put the water through various cleansing mechanisms to remove chemical and solid contaminants. The various stages involved in the process of EC will take care of that.

What are the Basics Components of the System?

For your EC system to work, it requires a few basic tools. The first one is a proprietary treatment chamber to provide space for discharging and circulating electric current through the wastewater. This chamber is necessary for getting rid of heavy metals, pesticides, bacteria, arsenic, cyanide, dissolved mineral salts and viruses among other harmful components. Secondly, the EC system also comes with a reactor comprising an anode, cathode and numerous of sets of conductive plates. Here, electrolysis occurs for further chemical purification of the wastewater, enabling you to remove metals, particles and dissolved inorganic pollutants in the wastewater.

What Reactions Take Place in the Reactor Cell?

  • Breaking Emulsions - fats and oils are a common contaminant of wastewater. They occur in form of emulsions and suspensions because fats and oils cannot dissolve in water. Emulsion breaking breaks down these fats and oils into harmless oxygen and hydrogen molecules, which are the primary components of clean water.
  • Seeding - seeding is necessary for removing dissolved metal ions from the wastewater. The process takes place at the anodes, which form precipitation centres for the metal ions. The ions accumulate at the anodes and precipitate out as large insoluble particles.

If you want to establish a wastewater recycling centre, an EC system is a reliable option compared to other systems relying on a single process like filtration. Reach out to professionals like Geoff Barton to learn more.
