Sludge Monitoring & Management

We collect, treat and recover hundreds of thousands of tonnes of wastewater treatment sludges each year. We also manage the sludge generated from the treatment of over a billion litres of drinking water annually. Our sludge services include the compliant transport to our licensed facilities where it is processed, treated and recovered.

Optimal Performance and Energy Efficiency for Activated Sludge Processes

Our water services team work with our customers to tailor solutions for the optimal performance of activated sludge processes. Our process involves evaluating representative sludge and influent samples in our INAB accredited (reg. scope 185T) laboratory. The evaluations can range from standard analytical review to extended laboratory scale.

By interpretation of the reported results, Enva develops tailored solutions ranging from biological augmentations and bespoke chemical products to consultative advice on operational efficiencies.

Our experienced team continue to follow up with regular monitoring to ensure optimal performance and reduced costs.

Our range of tests for analysing activated sludge include but are not limited to:

  • COD & BOD
  • Nitrogen
  • Phosphorous
  • pH & conductivity values
  • Metals content
  • Biomass DNA Testing
  • Toxicity
  • Dissolved Oxygen
  • Solvent Screening of Influent
  • MLSS, MLVSS & SVI

Alum Sludge

Enva manages the alum sludge generated from the treatment of over a billion litres of water annually.  Our sludge collection services include the compliant transport of alum sludge to our licensed facilities where it is processed, treated and recovered.

Organic Sludge

Our sludge recovery solutions are fully traceable and compliant. We transfer, treat and recover thousands of tonnes of organic material each year. Employing the latest technologies in composting, lime stabilisation, digestion and thermal treatment for the beneficial re-use of organic material, our recovered fertilizer is fully compliant.
