Various aeration blenders

Various aeration diffusers used for sewage treatment in sewage treatment plants are divided into two types of porous keyfilters and non-porous diffusers. The most common type of diffusers is doppler, dome, disk and tube.

Types of aeration blowers

Aero blower types
Aeration blower or air blower for blowing air into the pipes then into the diffusers of the wastewater treatment plants. The air blower is also used for air blowing in pools and fish huts and jacuzzis. In sewage treatment plants, in the activated sludge activated sludge unit, EAAS, MBBR, or IFAS or other aerobic processes are used.

Types of ion exchange resins

Types of ion exchange resins include strong acid cationic resins, weak acid cationic, strong anion, weak anionic play, and Chelatin resins. Cationic and anionic resins are widely used in water treatment.

Septic tanks

Septic tanks are the simplest and most commonly used unit for sewage treatment, especially human health sewage. Septic tanks have different applications. Septic can be used for storing the sewage tank to pump it into the main purification package. The septic tank can be pre-treated by flotation processes, such as sedimentation. These septic tanks are widely used in residential and residential complexes, residential and office complexes, construction and construction workshops, manufacturing and industrial factories, hotels, restaurants, and recreational and sports complexes.

Suggested treatment methods

The proposed sewage treatment methods, depending on the industry, require that the sewage be treated with biological or chemical processes during different purification processes, such as pre-treatment and refinement. During the purification process, those chemical and hazardous compounds for biological processes are reduced to the desired extent. Due to the high concentrations of organic materials, the wastewater industry is more similar to human wastewater and can be treated with biological methods. As can be seen below, the proposed purification methods are varied and different with respect to the type of industry and quality of sewage.
