to meet the unique needs of each of our clients.

Spesialising in optimising waste water treatment plant design, including process and structural optimisation

In-house geotechnical as well as structural capabilities

We develop Sludge Centres for our clients where sludge treatment can be optimised to be more economical and cost-effective

Specialist plant, process, and
equipment reviews, including
refurbishment assessments

Some of our recent successes in converting existing infrastructure, increasing the plant capacity and effluent quality:

INTEGRATION OF TRICKLING FILTERS
AS A SIDE STREAM INTO A BNR TREATMENT PLANT

BENEFITS

  • Load reduction to themain treatment system
  • Utilising existing infrastructure
  • Capex and energy saving by utilising existing infrastructure while maintaining BNR effluent quality
  • Recent side stream application has reduced aeration requirements to be less than 15kWh per Ml

TPET® – THAROLLO POND ENHANCEMENT TREATMENT PROCESS

Pre-treatment Process ideal for clients with existing ponds. Can be combined with Trickling Filters or Activated Sludge.

BENEFITS

  • 30 to 70% loadreduction
  • Settling of Algae
  • Utilising existing infrastructure
  • Capex and energy saving by utilising sunlight

Domestic and International partnerships offer cutting edge technologies into the African market

Advanced BNR systems

▇ SND (SIMULTANEOUS NITRIFICATION AND DENITRIFICATION)

Technology Partner in USA with more than 30 years of experience and more than 700 Orbal applications.
Designed to provide majority of Oxygen at a deficit. This allows more nitrification while converting simultaneously the nitrate to nitrite to Nitrogen gas.

BENEFITS

  • Less Carbon and energy required for Aeration and nitrogen conversion, allowing pre-treatment to divert more carbon and generate more electricity
  • Smaller Footprint
  • Only use the energy required
ANAEROBIC DIGESTION AND GAS TO ENERGY

HIGH SOLIDS LOADING DIGESTION

BENEFITS

  • Utilise existing infrastructure
  • 300% Capacity increase
  • Low power and heat demand
  • Low polymer demand
  • Customisable capacity
▇ OPTIMISED WASTE WATER TREATMENT PLANT DESIGN INLCUDING PROCESS AND STRUCTURAL OPTIMISATION

BENEFITS

  • Circular design with combined reactor
    walls
  • Optimised structural design
  • Compact geometric layout
