In this piece, you’ll learn about different sewage treatment systems and SUSBIO ECOTREAT – India’s most advanced modular STP. This future-ready solution tackles sewage treatment plant problems while keeping service costs in check.
How Modular STPs Work in 2025
Modern modular sewage treatment plants transform wastewater into reusable water through multiple stages. These systems in 2025 deliver exceptional performance from a smaller footprint by combining advanced technology with compact design.
Screening and Grit Removal Process
The treatment starts when large debris gets filtered out to protect downstream equipment. Current 2025 systems feature two screening phases: coarse screens (6mm or larger openings) catch bulky materials like rags and plastics, while fine screens (1.5-6mm openings) capture smaller particles that could affect later treatment stages. Wastewater then moves to grit chambers where the flow slows down. Heavy materials like sand, gravel, and coffee grounds settle at the bottom. This crucial step helps prevent equipment wear and abrasion. Mechanical screening paired with grit removal gives pumps and downstream components the protection they need.
Biological Treatment Using MBBR Technology
Most modular STPs in 2025 use Moving Bed Biofilm Reactor (MBBR) technology at their core. This innovative method combines activated sludge and biofilm processes to achieve superior results. MBBR systems use special plastic carriers with density close to water (0.9g/cm³) that float freely in the aeration tank. These carriers create an extensive surface area where microbes can grow and break down organic pollutants efficiently. Fine bubble aeration systems feed oxygen to the biofilm and support aerobic microbial activity. The continuous movement stops biomass from building up and spreads microorganisms evenly, which streamlines processes. MBBR systems are nowhere near as space-hungry as conventional ones, needing 30-40% less room – perfect for modular applications with limited space.
Tertiary Treatment: UV and Membrane Filtration
The water goes through additional purification after biological treatment:
- UV Disinfection: Low-pressure UV systems work at wavelengths between 250-270 nm to damage microbial DNA and stop reproduction. A dose of 164 mWs/cm² reduces Total Coliform Count by 3 logs while completely eliminating Fecal Coliform, Pseudomonas, and Staphylococcus.
- Membrane Filtration: Microfiltration (MF) with 0.1-10 μm pores removes bacteria and turbidity. Ultrafiltration (UF) with smaller 0.001-0.1 μm pores catches viruses, endotoxins, and proteins. These advanced filtration technologies ensure water quality meets strict standards.
Effluent Reuse for Irrigation and Flushing
Modular STPs produce high-quality treated water that becomes a valuable resource. The 2025 treated wastewater supports many reuse applications – mainly irrigation, toilet flushing, cooling towers, and construction activities. Real estate sector just needed 101.9 MLD of water in 2019, which treated effluent could largely supply. Ready-mix concrete plants used 6,740 million liters of water for estimated concrete production of 22,46,262 cum/month—another way to use treated wastewater. SUSBIO ECOTREAT, India’s most advanced modular STP in 2025, makes this circular approach possible with its zero-sludge generation system and advanced water quality standards, which ended up reducing dependence on freshwater sources.
Smart Design Features That Define Modern Modular STPs
Modern modular STPs showcase remarkable design innovations that solve traditional sewage treatment challenges. Smart features have revolutionized wastewater management approaches in 2025.
Plug-and-Play Setup with Containerized Units
Pre-engineered and factory-assembled modular STPs cut installation time compared to conventional systems.

Containerized STPs work perfectly for emergency situations, construction sites, and remote locations. Modular units become operational within weeks after delivery – a huge advantage for businesses that face urgent wastewater management challenges.
Wireless Monitoring and Remote Access Panels
Smart monitoring systems in modern STPs have changed maintenance protocols:
- Live monitoring of parameters like flow rate, pH levels, and pollutant concentrations
- Microprocessor-based controllers with HMI, PLC, and VFD capabilities
- Remote access via SCADA systems for off-site oversight
- AI algorithms detect system faults and generate timely alerts
Operators can access live data and control system parameters from anywhere through wireless integration. This enables centralized management without constant on-site presence.
Low Power Consumption and Auto-Controlled Systems
Systems use up to 30% less power than traditional STPs, making energy efficiency one of their best features. SUSBIO ECOTREAT, India’s most advanced modular STP, uses 90% less electricity than conventional systems.

Compact Footprint for Urban and Remote Installations
Space-efficient design needs 40-60% less area than conventional systems. These units fit perfectly in constrained locations like urban environments or industrial facilities. Easy transportation and placement within existing infrastructure happens through containerized or skid-mounted configurations without major land clearance.
Advanced Microfiltration and Disinfection Units
State-of-the-art filtration technologies, including membrane filtration and UV disinfection, raise water quality standards. Chemical-free treatment options reduce environmental impact and operational costs. Integration with predictive maintenance stops 90% of potential failures. This ensures consistent performance throughout the system’s lifespan.
Comparing STP Plant Types and Modular Configurations
The right sewage treatment solution depends on knowing the differences between available setups. Each type comes with its own advantages that match specific project needs.
Containerized vs Skid-Mounted Modular STPs
Standard shipping containers house treatment equipment in containerized units, which makes transportation and installation easier on simple foundations. These self-contained systems work best for smaller projects and temporary setups where mobility matters. Skid-mounted modules rest on frames that forklifts or cranes can move, which makes them perfect for sites that just need periodic upgrades or changes. Teams can switch individual modules to add treatment steps while operations continue. SUSBIO ECOTREAT provides both options with features that are a big deal as it means that standard modular capabilities.
Modular Type STP vs Traditional ASP Systems
Traditional Activated Sludge Process (ASP) systems are common but take 8-12 hours for treatment, while MBBR-based modular systems only take 4-6 hours. ASP plants use more energy and create more sludge. MBBR systems handle shock loads better because of their stable biofilm formation. It also manages variable effluent conditions more effectively, which makes it perfect for decentralized applications. Yes, it is these modular treatment systems that deal with centralized facilities’ limitations through eco-friendly, decentralized methods.
Scalability and Upgrade Paths in Modular Designs
You can expand modular designs without major redesign work. Projects can start with minimal modules and add units as they just need more capacity. Communities can adapt to changing requirements this way without wasting resources. Modules work in other projects during relocation, which extends their investment value. This flexibility creates custom solutions that match specific capacity needs, space limits, and discharge requirements.
Cost of New Sewage Treatment Plant vs Retrofit Options
Modernizing existing infrastructure saves money significantly. A case study shows modernizing a 20-inch water main cost INR 84.38 million compared to INR 210.95 million for new construction. Notwithstanding that, modernization involves complex permits and operational challenges. Aging facilities with limited space or budget constraints can improve efficiency and compliance without complete replacement.
