Sewage Treatment Systems for Municipalities, Villages and Townships

STP System Overview
STP System Details

The sequence batch reactor (SBR) process is enhanced with ESBR_prime systems where aerobic granular sludge (AGS) replaces activated sludge in treatment. Sewage treatment plants with ESBR_prime systems are capable of removing nutrients such as ammonia and phosphorous biologically without additional treatment facilities or chemicals. Additionally, AGS settle rapidly reducing the settling time to a few minutes, thus enhancing the SBR's capacity to treat higher wastewater volumes.

Key Features:

  • Biological nutrient removal (ammonia and phosphorous)
  • Rapid settling time (few minutes)
  • Lower aeration demand compared to other aerobic processes
  • Fully automated control mechanisms
  • Multiple reactor modules for parallel operation
  • Intelligent management system with multi-level communication

Process Steps:

Treatment Cycle Process

1. Filling + Clear Water Removal

Treatment commences when wastewater from the collection tank is pumped into the bottom SBR reactor in a flow-controlled manner. The anaerobic reaction starts the treatment of incoming wastewater.

2. Aeration

Within the aerobic granular sludge different zones, including anaerobic, anoxic, and oxic regions, are maintained while aerating the SBR reactor. Aeration is facilitated by measured and time-controlled fine bubble diffusion.

3. Sedimentation

Once the aeration process is completed, the air supply is discontinued, and the fast settling sludge settles at the bottom of the reactor, leaving a clear water zone at the top.
