Sewage and Effluent Testing

Sidebar Image

With our company origins in the effluent industry we remain a leading provider of influent and effluent analysis for a wide range of treatment plants

We provide assistance to effluent treatment plant operators and owners, and because all consents are different, we have developed a wide range of test types to cover them. This ranges from the characterisation of influent, through the process to the final effluent quality, and also includes sludge and air quality tests.

Please also see our Trade Waste Testing page.

Process control including Influent & Final Effluent Characterisation

Eurofins-ELS offers assistance to treatment plant operators by analysing process samples for a range of different parameters. This may be

  • Biochemical Oxygen Demand (BOD)
  • Chemical Oxygen Demand (COD)
  • Dissolved Oxygen
  • Metals
  • Nitrate
  • Nutrients to check the efficiency of a nutrient removal plant
  • Oil and Grease to check for saponification
  • Sludge Volume Index
  • Suspended solids
  • Volatile Solids

Biofilters

Biofilters are organic odour reduction beds, but require maintenance to perform at their best. This usually requires regular addition of water, pH buffers, and nutrients.

Sludge

Tests that Eurofins-ELS can offer include:

  • Arsenic
  • Cadmium
  • Chromium
  • Copper
  • Cryptosporidium
  • Enteric viruses
  • Faecal coliforms
  • Giardia
  • Helminth ova
  • Iron
  • Lead
  • Mercury
  • Nickel
  • Nitrogen
  • Organo-Chlorine Pesticides
  • pH
  • Phosphorus
  • Potassium
  • Salmonella
  • Zinc

Landfill Disposal

Please see our Landfill Testing page.

Land Disposal

Eurofins-ELS offers a nutrients analyses service to monitor the effect of the discharge on ground and surface waterways.

Receiving Waters

There are a number of disease-causing pathogens that once discharged into the marine and freshwater ecosystems can survive for some time. Testing from both a freshwater and marine environment is performed as part of a regular monitoring program designed to minimise the risk associated with recreational and fishing activities.

Shellfish

Mussels are filter feeders and are known to concentrate contaminants such as metals and viruses. Even though virus infection is specific to the species it came from, they can live long enough inside a mussel to return back to a human host. Eurofins-ELS can provide a testing service to monitor the health of a receiving water environment.

Data Reporting

Often our work requires us to present our data in very specific formats. This includes spreadsheet or csv formats designed to integrate with our customers own systems. Automation of this process allows for simplification and minimisation of transcription errors.

These spreadsheets are used on a daily basis to ensure compliance to a range of consent conditions including:

  • Geometric mean of 90 consecutive values
  • Compliance against rolling month values
  • Individual maximum allowable values
