Product Description

STP plant treats the sewage to make it fit for safe disposal, agricultural use or domestic use in toilets etc. Sewage usually contains a high quantity of organic and inorganic wastes. It is essential to treat sewage before it enters into any water body.

There are three main stages of the wastewater treatment process, aptly known as primary, secondary and tertiary water treatment.

How STP Plant works?

Wastewater and sewage, usually from a number of properties, are fed into the primary settlement tank where solids and liquids separate and the liquor flows into the biozone chamber. In the chamber, a pump aerates the waste and encourages good bacteria to digest the organic matter, breaking it down and purifying it.

What is MBBR process?

The MBBR process utilizes floating plastic carriers (media) within the aeration tank to increase the amount of microorganisms available to treat the wastewater. The media provides increased surface area for the biological microorganisms to attach to and grow in the aeration tanks.

What is MBR STP?

Membrane Bioreactor or MBR Sewage Treatment Plant is an innovative wastewater treatment method. As the name suggests, it combines two technologies, membrane filtration and the biological treatment.

What is difference between MBR and MBBR?

MBR stands for Membrane Bio Reactor and is a combination of a membrane process like ultra filtration and the activated sludge process.

MBBR is the short form for Moving bed bio reactor which uses free floating plastic fill media for attached Biofilm growth

Key Features & Technical Highlights

What Sets Our STP Plants Apart

Every sewage treatment plant manufacturer claims quality. Here is what actually comes with a Unitech-built system:

  • Modular & Scalable Design — Plants are available from 10 KLD to 500 KLD. Need to expand? Add modules without rebuilding the entire system.
  • PLC-Automated Operation — Fully automated controls reduce manual intervention and maintain consistent treated water quality around the clock. Our Water Treatment Plants follow the same automation-first philosophy across all product lines.
  • Stainless Steel & FRP Construction — Corrosion-resistant materials extend plant life and reduce long-term maintenance costs significantly.
  • Advanced Biological Treatment — Our MBBR sewage treatment plant units use high-surface-area plastic biofilm carriers that maximise microorganism activity, delivering superior BOD and COD reduction.
  • CPCB-Compliant Output — Treated water meets Central Pollution Control Board discharge standards for safe environmental release or reuse.
  • Low Footprint Installation — Compact design fits within tight site constraints. Underground installation options are available on request.
  • Energy-Efficient Configuration — Optimised aeration systems reduce power consumption without compromising treatment efficiency.

For projects requiring pre-treatment before the STP stage, our Filtration System effectively removes suspended solids and turbidity from incoming feed water.

Applications — Industries We Serve

Who Needs a Sewage Treatment Plant?

A packaged sewage treatment plant from Unitech Water Solution is actively deployed across a wide range of sectors:

  • Residential & Commercial — Housing societies, apartment complexes, gated communities, and commercial office parks use our compact STP units to treat domestic wastewater for toilet flushing and landscaping reuse.
  • Hospitality & Healthcare — Hotels, hospitals, and resorts generate high-volume sewage daily. Our systems handle fluctuating loads reliably while meeting stringent hygiene and discharge standards. Many of these facilities also pair our STP systems with our Ultra Filtration Plant for higher-quality treated water output.
  • Industrial Facilities — Factories, manufacturing units, and food processing plants require robust industrial sewage treatment capacity. Where process water hardness is a concern, our Water Softening Plant is often integrated upstream of the STP system for better overall performance.
  • Institutional & Educational — Schools, colleges, and government campuses across Gujarat and India rely on our MBBR sewage treatment plant systems for decentralised, low-maintenance wastewater management.
  • Real Estate & Infrastructure — Builders and township developers integrate our turnkey STP systems during the construction phase for seamless, compliant operations from day one. Projects that require pure water alongside wastewater management often combine our STP with an Industrial RO Plant for a complete closed-loop water solution.

Why Choose Unitech Water Solution?

16+ Years. Hundreds of Projects. Zero Compromise.

Choosing the right sewage treatment plant manufacturer is a long-term decision. Here is why industrial buyers and project developers across India choose Unitech Water Solution:

We manufacture everything in-house at our Vatva GIDC facility in Ahmedabad — no middlemen, no quality shortcuts. Our plants carry ISO 9001:2015 certification and are built in compliance with BIS, FSSAI, and CPCB norms. We have successfully exported systems to Africa, the Gulf, and the Middle East, which means our engineering standards are tested globally, not just locally.

Every project comes with complete turnkey support — from initial site assessment and system design to installation, commissioning, and after-sales service. Our engineers stay involved after handover, not just before the sale. We offer custom capacity configurations, so you pay only for what your project actually needs.

FAQs


We manufacture sewage treatment plants ranging from 10 KLD to 500 KLD. Custom capacities beyond this range are also available based on your project's site conditions and daily sewage load requirements.

Yes. Every sewage treatment plant we build is designed to meet CPCB discharge norms. Treated water output meets the required BOD, COD, and TSS parameters for safe environmental discharge or reuse.

A packaged sewage treatment plant is a pre-engineered, factory-built STP unit that is compact, ready to install, and ideal for sites with space constraints. It combines all treatment stages in one integrated, low-maintenance system.

Our plants use MBBR, and SBR technologies depending on your capacity, space, and treated water reuse requirements. Our Water Treatment Plants page covers all available technology options in detail.

Yes. Treated water from a properly designed sewage treatment plant meets standards for reuse in toilet flushing, garden irrigation, cooling towers, and industrial process applications — reducing freshwater dependency significantly.
