About

• Site preparation and layout:The site is prepared, and the layout of tanks, pumps, and piping is determined based on the plant's design and capacity.
• Underground and structural work:Foundation work, excavation for tanks, and the construction of concrete and steel structures are completed.
• Installation of equipment:Pipes, screens, pumps, and other equipment are installed according to the design specifications.
• System integration:All components are connected, and the control and automation systems are integrated to ensure the plant operates efficiently.

• Preliminary treatment:
  • Bar screens:Remove large floating debris like plastic and paper.
  • Grit chambers:Remove heavy inorganic materials like sand and gravel.
• Primary treatment:
  • Primary sedimentation tanks:Allow sewage to settle, separating solids (sludge) from liquids (effluent).
• Secondary treatment:
  • Aeration tanks/Biological reactors:Use aerobic microorganisms to break down dissolved and suspended organic matter.
  • Secondary clarifiers:Separate the activated sludge (microorganisms) from the treated water.
• Tertiary treatment:
  • Filtration and disinfection units:Final stage to further purify the water and kill pathogens before discharge or reuse.
• Sludge handling:
  • Sludge treatment and disposal:Manage the byproducts from the primary and secondary stages, which can involve dewatering and other processes.

• Worker safety:Personal protective equipment (PPE) such as helmets, gloves, and safety shoes are mandatory. Masks and goggles are required during sandblasting.
• Site management:Proper storage of materials, regular removal of waste, and the use of scaffolds for elevated work are essential.
• Hazard control:Barricades are used around trenches, and safe means of access and egress are provided for all elevated work areas.
