Underground Sewage Treatment Plant (STP) for Hotels, Restaurants

Underground STP Manufacturers in Hyderabad, Mumbai, Pune, Kolkata, Bangalore, Chennai, Delhi, India.

undergrnd_stpThere are areas among the cities, cities and villages that are impossible to hide beneath centralized wastewater treatment system, to offer excellent answer for the identical, SD Enviro Engineers steps during this field.

SD Enviro Engineers package sewage treatment plant type wastewater treatment system is compact, effective and economical for wastewater treatment in decentralized manner.

SD Enviro Engineers provide a broad spectrum of packaged sewage treatment systems to handle domestic and industrial sewage originating from industrial residences, giant commercial complexes, small and medium industries. Standard modules facilitate a shorter delivery period.

The utterly pre designed units require terribly less civil works and will be erected and commissioned in a short time span. The pre fabricated units are independent of web site location (i.e.) in places where there’s space constraint or price of house is very high, these units can be located either on the high of the building, structures or in the basement.

Working Principle /Process/operation:

The packaged units work on a media based biological degradation. The specifically developed media created from UV stabilized and chemically resistant propylene offers an ideal condition for growth of micro organisms to degrade the incoming organic contaminants.

The use of media conjointly reduces the aeration tank sizes substantially thereby reducing the footprint of Sewage Treatment plant. The process air needed is provided by means of dual lobe kind air blower which transfers air through rugged EPDM diffusers. The media conjointly substantially reduces the sludge generation from these units.


Moving Bed Biofilm Reactor (MBBR) processes improve reliability, simplify operation, and need less house than ancient wastewater treatment systems.

MBBR technology employs thousands of polyethylene biofilm carriers operating in mixed motion inside an aerated wastewater treatment basin. Each individual biocarrier increases productivity through providing protected surface area to support the expansion of heterotrophic and autotrophic bacteria inside its cells. It is this high-density population of bacteria that achieves high-rate biodegradation within the system, while conjointly providing process reliability and ease of operation.

This technology provides price-effective treatment with minimal maintenance since MBBR processes self-maintain an optimum level of productive biofilm. Additionally, the biofilm connected to the mobile biocarriers at intervals the system automatically responds to load fluctuations.

Advantages of Package Sewage Treatment Plant :

  • Small Footprint
