In the current market, many so-called capsule systems are FRP/ Syntex tank-based units, which primarily function like modified septic tanks rather than complete treatment plants.
Not Just a Tank – Complete Engineered STP: Typical systems only provide a tank with MBBR media, without proper process design. They generally lack aeration, filtration, sludge handling, and disinfection systems, resulting in incomplete treatment.
Missing Critical Treatment Stages:
Such systems do not include essential components like:
✔ Proper aeration system
✔ Tertiary filtration (PSF/ACF)
✔ Sludge handling mechanism
✔ Disinfection & dosing system
Due to this, they only perform partial settling, similar to a septic tank.
• Performance Issues Over Time:
After a certain period:
✔ Tanks get filled and choked
✔ No significant improvement in water quality
✔ Efficiency drops drastically
✔ Frequent cleaning and operational issues arise
