An MBBR STP Plant is an advanced biological wastewater treatment system that uses biofilm carriers suspended in the aeration tank to efficiently treat sewage. The MBBR (Moving Bed Biofilm Reactor) technology combines the benefits of suspended growth and attached growth processes, ensuring high treatment efficiency with a compact design.

It is widely used for treating domestic sewage and light industrial wastewater with consistent and reliable performance.

In an MBBR system, specially designed plastic media (bio-carriers) move freely inside the aeration tank. Microorganisms grow on these carriers and break down organic pollutants as air is supplied through diffusers. The treated water then flows to a settling tank where sludge is separated.

• High Treatment Efficiency – Excellent removal of BOD, COD, and TSS
• Compact Design – Requires less space compared to conventional systems
• No Sludge Recycling Required – Simplified operation
• Shock Load Resistance – Handles load fluctuations effectively
• Low Maintenance – Reduced operational complexity
• Expandable System – Easy capacity upgrade

An SBR STP Plant is an advanced biological wastewater treatment system that treats sewage in batch mode using a sequence of aeration and settling processes within a single tank. It is highly efficient, space-saving, and widely used for municipal and industrial sewage treatment.

The SBR (Sequential Batch Reactor) technology performs equalization, aeration, and clarification in one reactor, eliminating the need for multiple tanks and ensuring high-quality treated water.

1. Fill Phase – Sewage enters the reactor tank
2. Aeration Phase – Air is supplied to promote biological degradation
3. Settling Phase – Biomass settles at the bottom
4. Decant Phase – Clear treated water is discharged
5. Idle Phase – Preparation for the next cycle

A STP (Sewage Treatment Plant) for a hospital is a specialized wastewater treatment system designed to treat sewage and biomedical wastewater generated from hospital facilities. It ensures safe disposal or reuse of treated water while complying with strict environmental and health regulations.

Hospital STPs are engineered to handle high organic load, pathogens, chemicals, and pharmaceutical residues, making them more advanced than conventional sewage treatment systems.

• Advanced Treatment Technology – SBR / MBBR / MBR based systems
• High Disinfection Efficiency – Removes bacteria, viruses, and pathogens
• Odor Control System – Maintains hygienic surroundings
• Compact & Modular Design – Suitable for hospital premises
• Automated Operation – PLC / SCADA-based control
• Regulatory Compliance – Meets Pollution Control Board norms

A dosing skid for a Water Treatment Plant (WTP) is a compact, pre-assembled system designed for the accurate storage, preparation, and controlled dosing of chemicals used in water treatment processes. It is mounted on a skid (base frame) for easy installation, operation, and maintenance.

This system ensures precise chemical injection for processes such as coagulation, flocculation, disinfection, pH correction, and scaling control, thereby improving overall water quality and treatment efficiency.

• Pre-Assembled Skid-Mounted Unit – Plug-and-play installation
• High Dosing Accuracy – Consistent and controlled chemical injection
• Compact & Space-Saving Design
• Corrosion-Resistant Materials – Suitable for harsh chemicals
• Automated Operation – PLC-based or manual control options
• Safe & Reliable System – Minimizes operator exposure

A compact STP plant is a space-saving, pre-engineered sewage treatment system designed to treat domestic or industrial wastewater efficiently within a minimal footprint. It integrates multiple treatment stages into a single or modular unit, making it ideal for locations where space, time, and ease of installation are critical.

These plants are factory-built and delivered in ready-to-install condition, ensuring fast commissioning and reliable performance.

• Compact & Modular Design – Ideal for limited space installations
• Pre-Fabricated Unit – Quick installation with minimal civil work
• High Treatment Efficiency – Meets pollution control standards
• Low Power Consumption – Energy-efficient operation
• Automated Operation – PLC / timer-based control systems
• Low Maintenance – Easy operation and servicing
