Prefabricated STP or domestic wastewater treatment is the process of removing contaminants from wastewater and household sewage. It includes physical, chemical, and biological processes to remove physical, chemical and biological contaminants. Its objective is to produce a waste stream (or treated effluent) and a solid waste or sludge suitable for discharge or reuse back into the environment.

Normally
prefabricated stp requires large area for the proper
installation. Conventionally STP has been installed into the
bigger land. But nowadays industries and institution are installing
Sewage Treatment Plant for the benefit of the environment.
Land is the important part of any of the industries and institution
i.e. hospital, hotels, schools etc. and they are not able
to provide enough space for the conventional sewage treatment
plant.
Shubham INC has developed innovation and revolutionary nderground
stp and prefabricated stp(sewage treatment plant)
which consume very small area of the land and provide excellent
output quality of treated water. Underground STP and Package
Sewage Treatment Plant mainly consist of Primary clarifier
and settler, Aeration tank with bio media, tube setter, disinfection
system, Tertiary Treatment, Ultra filtration, UV system and
Ozonator.
Treatment scheme are vary upon application to usage basis.
Usually institutions want to recycle sewage treated water
for flushing and cooling tower application so they need very
efficient treatment of sewage.Shubham INC. make underground
stp and prefabricated stp type STP provides superior
quality of treated sewage which can be recycled anywhere into
different applications.
