Industrial Wastewater Treatment describes the processes that eliminate the pathogens from water produced by the industries.

Quite simply, industrial wastewater is water that has to be used in industrial manufacturing processes or commercial activities for making products. It is referred to as “wastewater,” industrial wastewater differs from municipal wastewater (also known as sewage) and domestic wastewater.
 
Let’s see how industrial wastewater is different from domestic wastewater and municipal wastewater.
 
Domestic Wastewater: This type of wastewater is generated from households that are been affected by human use. It is the wastewater produced from toilets, kitchen sink and bathtub drains.
 
Municipal Wastewater: Municipal wastewater or sewage is type wastewater that is released from the community of people such as mall and restaurants, and institutional and commercial facilities in the urban area. The wastewater usually travels from a building’s plumbing.
 
Industrial Wastewater:
Industrial wastewater treatment covers the mechanisms and processes used to treat water that removes dissolved toxic organic substances and hazardous chemicals and released to the environment. After water treatment process the treated water can be reused for a variety of purpose within the industry. Before
Most manufacturing industries release some wet waste to recycle and reuse it but recently the world has been minimizing such production or recycle such waste within the production process. 
 
Types of Industrial Wastewater:
Based on different industry and the contaminants; Industry wastewater types are listed below: 
 
Sectors Pollutant
Iron & Steel BOD, COD, acids, oil, phenols, cyanide, metals
Petrochemicals and refineries BOD, COD, acids, oil, phenols, cyanide, metals
Chemicals COD,  heavy metals, SS, organic chemicals, and cyanide
Mining SS, metals, acids, and salts
Microelectronics  COD and organic chemicals
Textiles and leather BOD, solids, sulfates, and chromium
Pulp and paper BOD, COD, SS, AOX, solids, chlorinated organic compound

Types of Industrial Wastewater Treatment Methods:

The treatment methods in which, the application of physical forces predominates. Some of the physical unit operations used for wastewater treatment is:
  • Screening
  • Mixing and flocculation
  • Sedimentation
  • Flotation and filtration
  • Gas transfer
are typical physical unit operations.
 
2. Chemical Unit Processes:
A treatment method in which, waste is treated by adding chemical reaction in order to remove waste.
  • Precipitation
  • Adsorption
  • Disinfection
These are the most common examples used in wastewater treatment.
3. Biological Unit Processes: This treatment method is brought by biological activity for removal of contaminants.
Primarily this kind of treatment is used to remove the dissolved and colloidal organic matter in a waste.
 
Top Industrial Wastewater Treatment Equipments:
 
The following list includes the most common types of industrial wastewater treatment equipment, how equipment operates, and its use affects the business profitability.  
  1. Ultrafiltration Systems: Ultrafiltration(UF) is a variety of membrane filtration which is used to remove emulsified oils, metal hydroxides, emulsions, suspended solids, dispersed material, and other molecular weight materials from wastewater. It is also used to remove small fines in deburring and tumbling from wastewater, coolant, and other solutions.

 

        2. Vacuum Evaporation and Distillation: Vacuum evaporation and distillation is a technique in which it removes the water from the contaminants, rather than filtering the contaminants from the water.
Three primary vacuum evaporation are:
  • Heat pumps
  • Hot water/cold water
  • Mechanical vapor recompression

    3. Paper bed filters: These types of equipment utilize disposable paper media or permanent filter media to produce a positive barrier by gravity. This technique removes solids from all free-flowing industrial process liquid.

4. Reverse Osmosis System: by using a semipermeable membrane, this type of equipment removes dissolved solids and impurities from water t allows the passage of water without any impurities in it. The filtered water that passes through the RO membrane is called permeate, and the eliminated dissolved salt is called as a concentrate.
5. Tramp oil separators: In this wastewater treatment solution, contaminated fluid flows through a series of baffles and a porous media bed, during which free and mechanically dispersed oils are separated from the fluid.
The objective of Industrial wastewater treatment equipment is to remove as much as suspended solids as possible before it discharged in the environment. 
 
The process of Industrial Wastewater Treatment: 
 
For industrial water treatment, the water passes through a series of five major steps:
  1. Preliminary treatment
  2. Primary treatment
  3. Secondary treatment
  4. Tertiary treatment
  5. Disinfection
1. Preliminary Treatment of Wastewater: The preliminary treatment is a series in which the wastewater entering a treatment plant called as influent to remove suspended solids that could clog pipes. This process involves screening operation to remove large objects, such as sticks, rags, leaves, sanitary products, rocks, toys, and rocks. Treatment plants are made up of steel or iron bars set in parallel about one-half inch apart.

2. Primary Treatment of Wastewater: This process use settling tank, also called a sedimentation tank or clarifier. In this process, a series of operations removes up to 50% of pollutant solids that will flow settle. These sedimentation tanks are designed to hold wastewater for several hours. During this time, the suspended solids can drift to the bottom of the tank, and floating material can be skimmed off.

3. Secondary Treatment of Wastewater: In the secondary treatment process is a highly controlled artificial environment, where the solid material flowing out of primary treatment is again treated in this series. This process removes solid materials, either flowing on the source, dissolved in the water, or both. This substance could be food particles, fungi, algae and varies of bacteria and microorganisms. 

4. Tertiary Treatment of Wastewater: The next stage improves the quality of water even more. This water treatment is designed to remove specific toxic substances that may be dissolved in the water stream.
 
5. Disinfection: Disinfection is the final stop in the treatment process before water is released to the environment. This water significantly reduces any remaining bacteria and virus and help protect the public from exposure of any pathogenic microorganisms.
