STP problems usually happen due to wrong capacity, poor aeration, flow variation, sludge issues, or weak process design. These can lead to odour, unstable treated water quality, high BOD/TSS, and compliance problems.
❌ Odour near STP area
❌ Poor treated water quality
❌ Sludge and breakdown issues
❌ Reuse water not suitable for flushing or gardening
Plizma Technology designs STP systems based on actual sewage flow, occupancy, space, peak load, reuse need, and compliance norms using suitable processes like MBBR, SBR, MBR, filtration, and disinfection.

How Does a Sewage Treatment Plant (STP) Work?
A sewage treatment plant treats domestic wastewater from apartments, hotels, hospitals, commercial buildings, and industrial facilities so it meets discharge norms or can be reused safely.
The process starts with screening and grit removal to remove solid waste, floating matter, and heavy particles. After this, equalization balances the flow and pollution load, helping the STP handle peak usage without sudden performance issues.
Biological treatment is the core stage of an STP. Technologies like
MBBR, SBR, or MBR help reduce BOD, COD, and organic load under controlled treatment conditions.
After biological treatment, clarification separates sludge from treated water. The treated water then passes through filtration and disinfection for final polishing, making it suitable for discharge or reuse depending on site requirements.
If your existing STP is giving odour, overflow, poor treated water quality, or compliance issues, it is better to review the system before the problem becomes costly. You can speak with Plizma Technology’s STP team for guidance on new STP installation, STP upgradation, or performance correction.

Advantages Of Sewage Treatment Plant
The advantages of a Sewage Treatment Plant are listed below:
Urban & Decentralized STP Installations
MBR plants are applied in space-constrained urban locations to meet CPCB discharge and reuse norms without conventional clarifiers.
Industrial Campus & Facility Sewage Management
MBR systems are used for treating domestic sewage from industrial premises where compact design and consistent effluent quality are required for internal reuse.
Domestic Sewage Treatment & Reuse
MBR sewage treatment plants treat residential and commercial sewage to produce low-BOD, low-TSS water suitable for flushing, landscaping, and utility reuse.
