We are Manufacturer, Supplier, Exporter of Sewage Treatment Plants (STP) from Pune, Maharashtra, India.

A Sewage Treatment Plant (STP) based on Submerged Aerobic Fixed Film (SAFF) technology utilizes a fixed-film process where microorganisms grow on submerged media to degrade organic matter in the wastewater. This method offers several advantages in terms of efficiency, space utilization, and operational simplicity. Here’s an overview of its applications and benefits


Municipal Wastewater Treatment:
  • Urban and Suburban Areas: Treating sewage from residential communities to meet discharge standards.
  • New Developments: Suitable for new housing projects and urban expansions.
Industrial Wastewater Treatment:
  • Food and Beverage Industry: Treating wastewater with high organic content.
  • Textile and Dyeing Industry: Managing effluents with organic and dye pollutants.
  • Small and Medium Enterprises: Industries needing compact and efficient treatment solutions.
Commercial and Institutional Facilities:
  • Hotels and Resorts: Ensuring effective wastewater treatment in hospitality settings.
  • Hospitals and Medical Centers: Managing wastewater containing organic and microbial pollutants
  • Schools and Universities: Treating sewage from educational institutions.
Remote and Decentralized Locations:
  • Rural Areas: Providing treatment solutions for small communities without centralized sewage systems.
  • Tourist Resorts: Ensuring minimal environmental impact in remote locations.


Efficient Treatment:
  • Effective Organic Removal: High efficiency in breaking down organic matter and reducing biochemical oxygen demand (BOD) and chemical oxygen demand (COD).
  • Stable Process: Offers consistent performance with high tolerance to load variations.
Compact Design :
  • Space-Efficient: Requires less space compared to traditional activated sludge systems, making it ideal for urban and space-constrained areas.
  • Modular Configuration: Can be designed in a modular format, allowing for easy expansion as treatment needs grow.
Low Maintenance:
  • Simple Operation: Less complex than some other advanced treatment methods, leading to easier operation and maintenance.
  • Durable Media: Fixed film media is robust and requires minimal maintenance.
Cost-Effective:
  • Lower Operational Costs: Reduced energy consumption compared to systems requiring high levels of aeration.
  • Reduced Sludge Production: Generates less sludge, lowering sludge handling and disposal costs.
Environmental Sustainability:
  • Water Reuse Potential: Produces effluent suitable for reuse in irrigation, toilet flushing, and other non-potable applications.
  • Reduced Environmental Impact: High-quality effluent helps protect natural water bodies and ecosystems.


Pre-Treatment Units:
  • Screens and Grit Chambers: Remove large solids and grit to protect downstream equipment.
  • Oil and Grease Separation: Removes fats, oils, and grease from the wastewater.
Primary Treatment:
  • Sedimentation Tanks: Allows settleable solids to precipitate out of the wastewater.
Biological Treatment (SAFF):
  • SAFF Reactors: Tanks with submerged media (plastic or other materials) where biofilm develops. The biofilm breaks down organic matter as wastewater flows over it.
  • Aeration System: Provides oxygen to support the aerobic microorganisms in the biofilm.
Secondary Clarification:
  • Secondary Settling Tanks: Allow the separation of treated effluent from the biological solids.
Post-Treatment (Optional):
  • Disinfection: UV treatment, chlorination, or ozonation to eliminate remaining pathogens if required.
  • Advanced Filtration: Polishing filters to further enhance effluent quality if needed.
Sludge Handling:
  • Thickening and Dewatering: Equipment to reduce the volume of sludge for easier disposal or further treatment.
  • Safe Disposal: Ensures sludge is treated and disposed of in an environmentally friendly manner.
Control and Monitoring Systems:
  • Automated Controls: Sensors and control systems for monitoring and optimizing the treatment process.
  • Remote Monitoring: Capability for remote supervision and management.


SAFF technology-based Sewage Treatment Plants offer an efficient and compact solution for wastewater treatment, providing high-quality effluent suitable for various reuse applications. The system's robust performance, low maintenance requirements, and cost-effectiveness make it ideal for municipal, industrial, and commercial settings, as well as for remote and decentralized locations. The environmental benefits, combined with its operational simplicity, make SAFF STPs a practical and sustainable choice for modern wastewater management needs.
