Pengolahan Limbah Cair Pada Industri Tekstil - Manajemen Limbah

Textile Wastewater Treatment Process
💧 The process begins with screening to remove large debris like plastic and fabric, preventing clogs in subsequent equipment.
📏 Equalization involves storing and balancing wastewater flow and pollutant concentration in tanks typically 3 to 5 meters deep, using mixers to maintain homogeneity.
🦠 Biological aeration utilizes microorganisms with the aid of blowers to supply continuous oxygen, aimed at decomposing organic matter such as BOD and COD in aeration units usually 4 to 6 meters deep.
🧪 Coagulation and flocculation use chemicals like alum to neutralize particle charges, followed by slow mixing to form larger flocs that settle easily.

Sedimentation and Final Checks
⬇️ Primary sedimentation separates suspended solids via gravity, allowing active sludge to settle at the bottom of tanks generally 3 to 4 meters deep.
✨ Chemical sedimentation occurs after coagulation/flocculation, where large flocs settle, yielding clearer water before final discharge.
🐠 Fish pond testing serves as the final indicator; if fish thrive, the treated water quality meets regulatory standards and is safe for the environment.

Key Points & Insights
➡️ Each stage—screening, equalization, aeration, sedimentation, and chemical treatment—is critical for pollutant reduction.
➡️ Homogeneity in the equalization tank is maintained via mixers to ensure the effectiveness of downstream biological treatment processes.
➡️ The visible transformation from highly turbid initial water to clear outlet water demonstrates the cumulative success of the multi-stage treatment system.
