Sewage treatment is vital for public health and environmental protection. By removing harmful pathogens and toxins from wastewater, treated water can be safely discharged or reused for non-potable purposes like irrigation and industrial processes, contributing to water conservation and sustainability.Our sewage treatment plant solutions in Pune, Mumbai, Nashik, Aurangabad, Goa, and Satara use advanced technologies to meet diverse needs:
- Activated Sludge Process (ASP): Efficient treatment in urban areas like Pune, Mumbai, and Nashik.
- Membrane Bioreactors (MBR): Ideal for high-demand applications in Mumbai and Goa.
- Sequencing Batch Reactor (SBR): Great for handling fluctuating flows in Aurangabad and Satara.
- Constructed Wetlands: Sustainable treatment for rural areas like Ahmednagar and Satara.
- Moving Bed Biofilm Reactor (MBBR): Effective for municipal and industrial sewage in Nashik and Goa.
- Fluidized Media Bio Reactor (FMBR): Advanced technology for large-scale applications in Goa and Nashik.
- Fluidized Aerated Bio Reactor (FAB): Efficient organic matter breakdown in Pune, Mumbai, and Aurangabad.
- Submerged Aerobic Fixed Film Reactor (SAFFR): High-quality effluent treatment across Maharashtra.
In a sewage treatment plant (STP), the process begins with sewage water passing through bar screens or a grit chamber to remove large solids. Following this, aeration or mixing in a tank introduces oxygen to break down organic matter. Primary sedimentation allows suspended solids to settle, while primary treatment adds coagulants to remove grit, coarse solids, oil, and grease. The effluent from primary treatment, still containing organic matter, undergoes secondary treatment where biological processes stabilize the organic material. The activated sludge method is commonly used, introducing active microorganisms into the sewage, followed by aeration and agitation. The aerobic conditions promote microbial oxidation of organic solids, resulting in coagulation, flocculation, and solid settlement, leading to a clear, odor-free liquid. After secondary treatment, the effluent undergoes tertiary treatment involving sand filtration and reverse osmosis to remove dissolved solids. The water is disinfected using UV radiation or chlorination before being discharged or reused. The specific treatment processes depend on the characteristics of the sewage and the quality of effluent after secondary treatment, ensuring effective water and wastewater management.
