About STP
What Is a Sewage Treatment Plant?
A Sewage Treatment Plant (STP) collects domestic wastewater from households, commercial establishments, and institutional buildings and treats it through a series of physical, biological, and chemical processes to produce treated effluent that meets CPCB or KSPCB discharge standards — safe for release to drains, water bodies, or reuse for irrigation and flushing.
In India, STPs are mandated by pollution control boards for townships above a certain population, all new industrial estates, and government housing projects. Municipal bodies require STPs to meet AMRUT and Smart Cities programme targets for 100% sewage treatment. Decentralised STPs serve residential complexes and campuses where connecting to a municipal system is not feasible.
RevoNext Waters specialises in MBBR-based and SBR-based STP designs — the most compact, reliable, and low-maintenance technologies for South Indian conditions. We also execute conventional activated sludge process (ASP) STPs for larger municipal schemes.
Who Needs an STP?
- Municipal bodies managing urban sewage networks
- Residential townships above 20,000 sq.m. (RERA)
- Hotels, resorts, and hospitality projects
- Hospitals and healthcare campuses
- IT parks and commercial complexes
- Educational institutions and campuses
Key STP Parameters We Design For
BOD: <10 mg/L
TSS: <10 mg/L
COD: <50 mg/L
pH: 6.5 to 8.5
Technology Choice
MBBR vs SBR — Which Technology Fits Your Project?
Both technologies achieve excellent BOD and TSS reduction. The right choice depends on your flow patterns, available footprint, and operational preference.
Most Common Choice
MBBR Technology
Moving Bed Biofilm Reactor uses suspended plastic carrier media to grow a biofilm that breaks down organic matter continuously. It is compact, robust, and handles flow variations well — making it ideal for most residential and commercial STPs.
Smaller Footprint
MBBR tanks are significantly more compact than conventional activated sludge systems
Handles Flow Variation
Continuous operation means it manages peak morning and evening sewage flows without performance drops
Lower Operating Complexity
Fewer mechanical components and a relatively simple process makes daily operation manageable
Larger Scale Projects
SBR Technology
Sequential Batch Reactor uses a fill-react-settle-decant cycle in a single tank. It offers higher flexibility in nutrient removal — particularly for nitrogen and phosphorus — and is well suited to larger municipal and industrial sewage treatment requirements.
Single Reactor Tank
Fewer civil structures required — the same tank handles aeration, settling, and decanting in cycles
Excellent Nutrient Removal
SBR cycles can be tuned for nitrogen and phosphorus removal when effluent limits are stringent
Suitable for Municipal Scale
Proven technology for large municipal STPs from 1 MLD upwards
Treatment Process
How an MBBR STP Works
A conventional WTP moves water through five main treatment stages. RevoNext Waters designs each stage with equipment matched to your raw water quality and output requirements.
1
Inlet Screening
Bar screen removes rags and solids at inlet
2
Equalization
Flow balancing tank smooths peak flows
3
MBBR Aeration
Biofilm on MBBR media degrades BOD and COD
4
Clarification
Tube settler or lamella clarifier removes sludge
5
Disinfection
UV or chlorination before treated water reuse or discharge

Equipment
STP Components We Manufacture
Grit Removal System
Grit chamber and detritor mechanisms that separate sand and inorganic grit at the inlet to protect downstream pumps and reactors.
Oil and Grease Skimmer
Surface skimming mechanism that removes floating oil, grease, and scum from primary and equalisation tanks.
Aerators
Surface and diffused aeration systems that supply dissolved oxygen to the biological reactor.
Clarifier Bridge Mechanism
Rotating bridge assemblies for continuous sludge and scum removal in circular clarifiers.
Sludge Scraper Mechanism
Bottom scraper arms that move settled sludge toward the central hopper for withdrawal.
Sludge Thickener
Gravity thickener mechanism that concentrates sludge before dewatering and reduces downstream load.
Sludge Dewatering
Filter press, screw press, or centrifuge dewatering equipment that cuts sludge volume for economical disposal, chosen to suit the plant.
Agitators and Mixers
Tank agitators and flash mixers for chemical dispersion and homogenisation.
MBBR Media
HDPE K3 and K5 carrier media for moving bed biofilm reactors, available for standalone supply to contractors.
Bar Screen
Manual and mechanically raked bar screens for STP inlet channel screening. Coarse and fine screen options.
UV Disinfection
Ultraviolet disinfection chambers for STP treated water. Chemical-free pathogen kill before reuse or discharge.
Frequently Asked Questions
Common questions about MBBR and SBR sewage treatment plant design and compliance.
MBBR (Moving Bed Biofilm Reactor) uses suspended plastic carrier media to grow a continuous biofilm that breaks down organic matter. It is compact, handles flow variation well, and is suitable for most residential and commercial STPs. SBR (Sequential Batch Reactor) uses a single tank operating in timed cycles: fill, react, settle, decant. SBR offers greater flexibility in nutrient removal (nitrogen and phosphorus) and is better suited to larger municipal schemes above 1 MLD.
