Many people do not spend a lot of time thinking about wastewater. After all, it is not exactly a pleasant topic. People like to think of water as a clean and clear liquid that they can drink and use to bathe themselves. However, once the water goes down the drain, it is no longer of the quality that can be used for these purposes. Of course, water is eventually going to be recycled, but this involves a cleaning process before it can be used for drinking and cleaning again.

If you do not have a lot of knowledge about wastewater, it is possible that you have a lot of questions. For example, you might wonder, can industrial water treatment be a good solution to preserve wastewater? How can I figure out how to filter wastewater? Where can I find reliable wastewater disposal? What is the best sewage wastewater treatment? Is there a sewage water treatment plant in my area? You can probably find the answers to some of these questions by doing your own research online, but it would also be a good idea to talk to someone who works in the field, who has the experience to be able to help you.

Industrial wastewater treatment systems are essential for maintaining the health of the environment as well as human populations. However, for these important processes to be carried out correctly, the right type of water treatment products and systems should be used. There are four major types of water treatment systems, which use different processes. Choosing the right system will help to meet the needs of each situation, whether it is to maximizing solids recovery or sludge dewatering.

Understanding wastewater treatment
Waste water, whether it originates from industrial and petrochemical plants or municipal usage, must be treated to remove all contaminants before it can be released back into the natural environment. This is essential to maintaining the health of the environment and to prevent pollutants from entering the water cycle. All wastewater streams have two kinds of contaminants, liquid and solid.
Both must be removed through a series of steps that will maximize solids recovery and also remove other contaminants like oil and dissolved chemicals. Current industrial waste water treatment systems use primary and secondary waste treatments which succeed in removing between 85% to 95% of all pollutants. As a final step, the wastewater is disinfected and then returned the natural local waterways.

Types of standalone wastewater treatment systems
Given the importance of removing contaminants from the wastewater, it is important to pick the right type of wastewater treatment system for each installation. These are the four main types of waste water treatment systems used for different purposes.

  • DAF or Dissolved Air Flotation systems
    DAF water treatment systems use compressed air under pressure to create bubbles on the water to be treated. This method is used to maximize solids recovery as the solid particles adhere to the bubbles and float to the surface, where they can be skimmed off.


  • Water oil separation system
    This type of water treatment plant is used when the waste water originates from oil and petrochemical facilities. The wastewater is passed through a separator where the oil fly oats upwards and a sludge with contaminants settles at the bottom.


  • Aerobic Treatment System
    This system has multiple stages, including pretreatment, aeration, settling, and disinfection and is used where the wastewater has a high proposition of organic waste. It differs from DAF systems because here the purpose of aeration is to speed up the digestion of wastes by the biomass.


  • Induced Gas Flotation System
    This system uses bubbles created by an impeller or other mechanical device to attract solid particles which them float to the surface and can be skimmed off.

Choosing the right wastewater treatment system is important on order to remove the maximum amount of contaminants. The treatment consists of several stages to maximize solids recovery and remove both organic and chemical contaminants. These processes are essential to maintaining human and environmental health.
