Hiraya Water offers both Water and Wastewater Treatment from planning, design, implementation, until commissioning and operation.

Areas of expertise in Wastewater:

  • Municipal Sewage and Septage
  • Agricultural Waste
  • Industrial Waste
  • Water Reuse

Areas of expertise in Water Treatment:

  • Surface Water
  • Groundwater

Hiraya boasts a long list of technologies within our expertise. We understand that no two projects are alike, and this long list assures that we provide our clients with options that are most appropriate for a diverse set of water and wastewater treatment challenges.

We believe in tried and tested technologies including the following:

  • Conventional Activated Sludge (CAS)
  • Sequencing Batch Reactor (SBR)
  • Moving Bed Bioreactor (MBBR)
  • Membrane Bioreactor (MBR)
  • Rotating Biological Contactor (RBC)

With primary consideration of cost (both capital and operational expenses), ease of use, and sustainability, Hiraya also generally designs using DEWATS for wastewater treatment. When sufficient land area is available, using DEWATS becomes the most advantageous option.

DEWATS is a collection of different treatment technologies, usually a combination thereof, to address wastewater challenges from both domestic and industrial sources. DEWATS promise a low cost (both capital and operational), easy to use, and fluctuation-resistant system.

DEWATS include the following technologies:

  • Grease Trap and Grit Chamber
  • Septic Tank
  • Imhoff Tank
  • Anaerobic Filter
  • Upflow Anaerobic Sludge Blanket (UASB)
  • Baffled Septic Tank
  • Fully Mixed Digester
  • Trickling Filter
  • Constructed Wetlands
  • Horizontal Gravel Filter
  • Vertical Sand Filter Ponds
  • Hybrid and Combined Systems
