Sewage Treatment Plants (STP)

Our sewage treatment plants are customized based on client requirements. While Activated Sludge systems are nearly obsolete, we recommend modern technologies like MBBR (Moving Bed Biofilm Reactor), SBR (Sequential Batch Reactor), or MBR (Membrane Bio Reactor) based on your specific needs.

MBBR Technology

MBBR Technology STP

The Moving Bed Biofilm Reactor (MBBR) process uses thousands of polyethylene biofilm carriers operating in mixed motion within an aerated wastewater treatment basin. Each carrier increases surface area for beneficial bacteria to grow, creating an efficient and compact treatment system.

Standard Components:

  • Stainless steel or epoxy-coated MS tanks
  • High-density polyethylene (HDPE) biofilm carriers
  • Fine bubble diffuser aeration system
  • Stainless steel or FRP reactor tanks
  • Clarifier unit with sludge return
  • Energy efficient blowers
  • Automated control panel

SBR Technology

SBR Technology STP

Sequential Batch Reactor (SBR) technology performs all treatment processes in a single reactor basin through timed sequences of filling, aerating, settling and decanting. This compact system provides excellent nutrient removal and operational flexibility.

Standard Components:

  • Stainless steel or epoxy-coated MS tanks
  • Submerged aerators with fine bubble diffusers
  • Programmable logic controller (PLC) system
  • Decanter mechanism for clear water extraction
  • Sludge dewatering system
  • Advanced oxidation process (optional)

MBR Technology

MBR Technology STP

Membrane Bio Reactor (MBR) systems combine biological treatment with ultrafiltration membranes, producing exceptionally high-quality effluent suitable for reuse. The membranes completely retain biomass, allowing for higher MLSS concentrations and smaller footprint.

Standard Components:

  • Stainless steel or epoxy-coated MS tanks
  • Hollow fiber or flat sheet ultrafiltration membranes
  • Fine bubble aeration system for membranes
  • Backwash and cleaning system
  • Automated permeate pump system
  • Advanced SCADA control system
  • Chemical dosing system for membrane maintenance
