Wastewater Treatment and Membrane Filtration Processes

26 Jun 2018

Water is perhaps one of the most endangered resources on our globe today and being an inhabitant of this planet, it becomes our responsibility to use and reuse it wisely. The major consumers of water are indeed the different industry sectors – be it refineries or industries producing food, chemicals, paper, etc. The water waste from these industries is very much likely to contaminate our ecosystem and the people living in it. And hence, there are laws today that demands every facility to be responsible for the proper discharge of the water waste as well as a treatment of wastewater before discharging it. However, you don’t have to stress over it too much as there are various effective membrane filtration systems available today such as Reverse Osmosis, Ultrafiltration, etc. which can help you and your facility a great deal. We will talk about them later in the blog.

 

Firstly, there are many factors that play a vital role when it comes to wastewater treatment for a production facility and it’s critical to determine that before getting on with the whole system of water filtration system. One of the major aspects of whether your facility needs to invest in an effective wastewater treatment system would be the “type” of water you are disposing of. Check whether your facility disposes of water carrying metal contaminants, or oil or grease or other inorganic sediments. If your facility does dispose of this kind of waste substances, then it is mandatory for you to venture into a powerful wastewater treatment system or you could be heavily fined for not doing so.

 

Yes, you might be wondering what to do now as you have found out about the “type” of waste your facility produces. One of the most established methods of cleaning industrial wastewater would be “Membrane Filtration”. This process was a bit expensive in the past but today it is possible for small or medium scale industries to benefit from such effective treatment systems. Based on the degree of filtration of the size of the water particles the membrane filtration system is divided into different filtration processes: reverse osmosis, nanofiltration, ultrafiltration, and microfiltration.

 

Reverse Osmosis:  Reverse Osmosis or RO is a process where a semipermeable membrane is used to filter or clean water from ions and other harmful contaminants.

 

Nanofiltration: Nanofiltration is very much similar to the Reverse Osmosis process however the difference between them is the level of filtering of nonmetallic elements.

 

Ultrafiltration: Ultrafiltration is a process where suspended solids and elements with high molecular weight can be removed from the water and it is almost similar to microfiltration. Both these processes differ basically in the degree of particle penetration.

 

Microfiltration: Microfiltration is a process which removes suspended particles and microorganisms (bacteria, sediments, algae, etc.) from liquid wastes.

 

Hence, these are the most used filtration processes in industry and if you are an industry owner than you must consider these processes for wastewater treatment as well as for water reuse. This way you will be contributing to saving our ecosystem as well as save yourself from any legal actions.
