Industrial wastewater treatment method
The working method of the industrial wastewater treatment package is selected based on the needs of industrial units and according to the type of wastewater of these centers. In general, due to the heavy nature of this type of wastewater and the presence of harmful substances and dangerous pollutants in it, special industrial wastewater treatment packages with special features are prepared and used.
Industrial wastewater is transferred to the industrial wastewater treatment package through piping. In the pre-treatment stage, suspended solids, grease and oil and other pollutants that may stick to the treatment equipment and damage them are separated from the wastewater solution.
In the physical treatment stage, easily separable pollutants are removed from the wastewater. Among the physical purification methods, we can mention coagulation and flocculation, filtration and ion exchange.
In the chemical treatment stage, pollutants that cannot be removed by physical methods are removed from the wastewater using chemicals.
In the stage of biological treatment, pollutants that are capable of biological decomposition are removed from wastewater by microorganisms, and then the treated wastewater is discharged into the environment through piping.
Based on this, the industrial wastewater treatment package is an efficient tool for industrial wastewater treatment that, by using different treatment methods, is able to remove pollutants in industrial wastewater and turn it into water with a suitable quality for discharge into the environment.
Due to the water crisis, today the industrial wastewater treatment package is considered an important and vital item in supplying water needed for various uses and is very valuable.
Design of industrial wastewater treatment device
Designing an industrial wastewater treatment device is a complex process that must be done with care and attention, and several parameters must be taken into account in order to do it correctly and completely. After checking these parameters, you can choose the appropriate purification methods.
Industrial wastewater refers to wastewater that is produced from industrial, production and service units and contains dangerous pollutants that can cause serious and extensive damage to the environment and human health. For this reason, industrial wastewater treatment is one of the most important measures to reduce environmental pollution and preserve human health, and has received a lot of attention in recent years. Accordingly, the design of equipment related to this industry is very complex and must be completed and set up by expert users.
Industrial wastewater treatment methods
Industrial wastewater treatment methods are generally divided into two categories:
Physical methods: In physical methods, pollutants that can be easily separated are removed from wastewater. Among the physical methods of industrial wastewater treatment, the following can be mentioned:
Coagulation and flocculation: Coagulation and flocculation is a physical method for removing suspended solids, heavy metals and other pollutants from wastewater. In this method, certain chemicals are added to the wastewater that cause coagulation of pollutants. Coagulating materials are usually aluminum chloride, aluminum sulfate or polyelectrolytes.
After coagulation, pollutants are suspended in water in the form of small clots. These clots are then deposited in sedimentation tanks and separated from the wastewater.
Filtration: Filtration is a physical method for removing suspended solids, chemicals, and microorganisms from wastewater. In this method, the wastewater passes through a filter bed. The filter bed can be composed of different materials such as sand, gravel, activated carbon or ion exchange resins.
Suspended solids and other pollutants are trapped in the filter bed and separated from the wastewater. The treated wastewater is then discharged through the filter.
Chemical methods: In these methods, chemicals are used to break down and separate the materials in the wastewater. Among the chemical methods for industrial wastewater treatment are chlorination, ozonation, advanced oxidation and ion exchange.
Chlorination: In this method, wastewater enters a tank along with chlorine. Chlorine reacts with organic substances in wastewater and oxidizes them. This reaction causes the destruction of organic matter and the reduction of BOD and COD of wastewater. Also, chlorine disinfects wastewater and destroys harmful microorganisms.
Ozonation: Wastewater enters a tank with ozone. Ozone reacts with organic substances in wastewater and oxidizes them. This reaction causes the destruction of organic matter and the reduction of BOD and COD of wastewater. Also, ozone disinfects wastewater and destroys harmful microorganisms.
Advanced oxidation: Wastewater enters a tank with a strong oxidizing agent such as hydrogen peroxide, potassium permanganate or hydrogen peroxide. The oxidizing agent reacts with the organic substances in the wastewater and oxidizes them. This reaction causes the destruction of organic, mineral and micro-organisms in the wastewater.
Ion exchange: Ion exchange is a chemical method for removing harmful ions from wastewater. In this method, ion exchange resins are used. Ion exchange resins contain specific ions that can be exchanged with harmful ions in wastewater. For example, ion exchange resins containing sodium ions can exchange chloride, sulfate, and other harmful ions in wastewater.
Wastewater is purified from harmful ions after passing through ion exchange resins. Harmful ions that have been transferred to ion exchange resins can be removed from the resins using special chemicals.
The difference between coagulation and flocculation, filtration and ion exchange methods
Industrial wastewater treatment is one of the most important measures to reduce environmental pollution and protect human health. In industrial wastewater treatment, various methods are used to remove pollutants in wastewater.
Physical methods of wastewater treatment separate pollutants from wastewater based on their physical properties. These methods are relatively simple and cheap, but may not be enough to remove some pollutants in one step and require several steps to perform optimally.
In chemical methods, pollutants that cannot be removed by physical methods are removed from wastewater using chemicals.
In biological methods, pollutants that are capable of biological decomposition are removed from wastewater by microorganisms. Among the biological methods of industrial wastewater treatment, the following can be mentioned:
After choosing the purification methods, the equipment needed for each of the purification steps can be determined.

The price of the industrial wastewater treatment package
The price of the industrial wastewater treatment package depends on various factors, including the following:
Type of treatment process: Industrial wastewater treatment processes are divided into two main categories: physical, chemical and biological, each of which has its own costs.
The amount of produced wastewater: the higher the amount of produced wastewater, the higher the treatment costs.
Quality of incoming wastewater: The quality of incoming wastewater affects the type of treatment process and its costs. The heavier the amount of imported industrial waste water and the higher its pollution level, the higher the price of the desired industrial waste water treatment package.
The quality of treated wastewater: this factor depends on the amount of pollutants in it. The higher the quality of treated wastewater, that is, the lower the amount of pollutants in it, the higher the treatment costs. The reason is that more complex and expensive purification processes are used to remove more pollutants.
For example, biological treatment processes are used to treat wastewater that contains large amounts of pollutants. These processes have more time and cost than physical and chemical purification processes.
Therefore, in order to reduce the costs of industrial wastewater treatment, efforts should be made to increase the quality of wastewater entering the treatment package as much as possible. This can be done by taking steps such as separating solids and oil from the wastewater before it enters the treatment package.
Used equipment: The price of the equipment used in the industrial wastewater treatment package, including pipes, tanks and other equipment, affects the treatment costs.
