Low civil work and low footprint
Easy relocation if required
Fully automated or semi-automatic operation
Suitable for 10–500 KLD apartment complexes
Attractive appearance and compact size
Odour-free and user-friendly

Package STPs are available in:

MBBR (Moving Bed Biofilm Reactor)
SBR (Sequencing Batch Reactor)
MBR (Membrane Bioreactor)
FMR/SAFF (Fixed Media Reactor)
based on treated water requirements.
