AEROBIC BIOCULTURE

AEROBIC ETP/CETP MICROBIAL CULTURE/BIOCULTURE FOR TEXTILE & DYE INDUSTRIES (CETP)

The effluents generated from textile dyeing units create significant environmental challenges for both the public and textile industries. Industrial wastewater treatment is one of the major problems in the present world. Generally, synthetic dyes can be categorised as anionic (direct, acid, and reactive dyes), cationic (basic), and non-ionic (dispersed dyes). Anionic dyes account for 20–30% of commercial dyes used in the industry. Among these, azo dyes represent the largest chemical class, comprising a wide variety of structures and colours, and they make up approximately 70% of the annual dye production.

Synthetic dyes are released into the environment through textile industrial effluents. While the quantity of dyes contributes only a small portion to overall water pollution, their vibrant colours make them noticeably problematic, even in minimal amounts. Tightening government legislation is forcing textile industries to treat their waste effluent to an increasingly high standard. The main pollutants found in textile effluents include recalcitrant organic compounds, colourants, toxic substances, inhibitory compounds, surfactants, and chlorinated compounds. During the dyeing process, 5–20% of the used dyestuffs are released into the process water. In addition to their visual impact and their contribution to chemical oxygen demand, many synthetic dyes are toxic, mutagenic, and carcinogenic.

Aerobic microbial culture plays a vital role in breaking down complex organic compounds found in textile wastewater. The application of aerobic bacterial culture treatment enhances the degradation process, leading to effective sludge reduction techniques. This wastewater treatment bacterial bioculture process aids in reducing biological oxygen demand (BOD) in textile effluents, ensuring control of wastewater odour and compliance with environmental regulations.
