FRP Bio Septic Tank
Lightweight & Corrosion-Resistant Sewage Treatment Solutions
What is an FRP Bio Septic Tank
An FRP Bio Septic Tank is a moulded Fibreglass Reinforced Plastic tank engineered to treat domestic sewage using natural biological processes. Its seamless, one-piece construction makes it inherently corrosion and rust-free, unlike metal or RCC alternatives.
These tanks are widely used in individual houses, villas, apartments, farmhouses, resorts, schools, and campsites where a lightweight, quick-to-install, and low-maintenance sewage treatment solution is required.
FRP Bio Septic Tanks installed by Togreen Infra Private Limited are designed to break down organic waste, pathogens, and suspended solids inside the tank through anaerobic bacterial action. Using a combination of biological and filtration processes, these systems make the treated discharge safer for the environment while remaining compact, durable, and easy to transport and install.
Why FRP Bio Septic Tanks Are Essential
Protecting environment and ensuring regulatory compliance
Environmental Protection
Untreated sewage cannot be released directly into the environment because it may contain pathogens and organic contaminants harmful to people, soil, and water bodies.
Water Source Protection
If left untreated, household wastewater can pollute surface and groundwater sources, damage ecosystems, and violate statutory pollution control norms.
Regulatory Compliance
Homes, institutions, and small establishments must comply with CPCB and SPCB statutory pollution control norms for sewage disposal.
FRP Bio Septic Tank Process Sequence at Togreen Infra
The typical process train inside a Togreen Infra FRP bio septic tank
Inlet Chamber
Receives raw sewage and reduces inflow velocity
Anaerobic Digestion Chamber
Bacterial breakdown of organic waste
Bio-Media Filter Chamber
Fixed-film bacteria attach and further treat waste
Clarification Chamber
Settling of remaining suspended solids
Aerobic Treatment
Further BOD reduction where required
Settling Chamber
Final solids separation before outlet
Sludge Storage
Compact storage with minimal accumulation
Outlet & Disinfection
Optional chlorination before safe discharge
This engineered sequence ensures stable operation, consistent effluent quality, and compliance with CPCB/SPCB discharge standards for a wide range of residential and institutional applications.
FRP Bio Septic Tank Process Overview
Sewage treatment with Togreen Infra's FRP tanks is a multi-stage operation
Preliminary Stage
Large solids removal and flow reduction as sewage enters the inlet chamber.
Primary Stage
Anaerobic bacteria digest organic waste inside the digestion chamber, reducing sludge and pathogens.
Secondary Stage
Bio-media filtration and aerobic treatment further reduce organic load (BOD/COD).
Tertiary Stage
Clarification and optional disinfection ensure the discharge meets legal standards.
