HECS PSTP - HECS - Packaged Sewage Treatment Plant


HECS Packaged STPs:

HECS brings to you a quality revolution in decentralized STPs in India. These state-of-the-art STPs are based on the proven MBBR technology and MBR technology, however it is optimized into a compact design which not only has unmatched merits but also meets the regulatory standards. These technologically advanced units are superior in every way to conventional sewage treatment plants and other packaged STPs available in the market.


These state of the art Packaged Sewage Treatment Plants are designed based on proven MBBR and MBR technologies respectively in an optimized compact design.

Capital cost is lower in comparison to conventional RCC Sewage Treatment Plants for Small and Mid Range Packaged Plants.

Only maintenance required is Monthly removal of plastics and desludging every six months. Operators are not required for Small and Mid Range Packaged Plants.

These Packaged Sewage Treatment Plants are designed to meet all parameters laid down by the MoEF & CC Standards

This Packaged Plant does not emit any smell except during maintenance. Sound is lower than 50db, similar to that of a mobile phone vibration.

The FRP tanks used are manufactured using state of the art machinery and are individually pre-tested to make it leak proof.

HECS Packaged STPs are available from a flow rate of 2KL/Day upto 500KL/Day

Capsule Design Suitable for 2-10KLD Sizes


Cylindrical Design Suitable for 15-100+KLD Sizes

Packaged Mitsubishi MBR STP

Plug and Play design with highest treatment capability for 20KLD – 200+KLD

  • Screening and Sedimentation Chamber collects the sewage and separates solid wastes / plastics from sewage. Sludge with higher density will settle at the bottom.
    Sewage then flows into anaerobic media chamber from screening and sedimentation chamber. Organic material which is decomposed by anaerobic microorganism alsonitrite and nitrate contained in the circulated water are converted into N2 gas by denitrification microorganisms.
    After anaerobic process partially treated sewage flows into the Aerobic Treatment Tank which is filled with MBBR media. Organic material contained waste water is decomposed by aerobic microorganism and converted to other materials such as carbon dioxide, water, and ammonia.
    This chamber has the function of settling sludge which is resulted by biological processes in the earlier chamber. Settled sludge will be transferred to the first chamber through a re-circulation line. The same air pump is used for this purpose.
    The treated water is disinfected when it comes in contact with the disinfectant chamber.
    The treated sewage is collected in the filter feed tank which can be pumped into filters for further treatment.
