Fit-for-purpose wastewater solutions
We assist our clients in dealing with difficult wastewaters. We select and utilise the most most appropriate technologies.
We specialize in helping customers with difficult wastewater problems. Our customers work in several industries:
Oil and gas
Sometimes getting rid of wastewater is as simple as transporting it to a municipal treatment facility. However most industrial wastewater often requires more complex solutions. The choices are limited by both technical and regulatory constraints.
We strive to understand these constraints before devising a solution.
All solutions must:
Meet regulatory requirements
Be technically feasible
Be fiscally sound
Present no harm to the environment
Wastewater discharge regulations are normally designed to protect surface waters and in some cases groundwater. There are even situations where air quality regulations impact wastewater treatment methods.
Environmental regulations vary to some degree from country to country and from state to state. Our staff works hard to understand the regulatory constraints so that appropriate and technically compatible solutions may be found. Whether the wastewater solution entails the eventual discharge into a stream, application to land or evapoconcentration there will be a mosaic of environmental regulations governing it.
For example, wastewater applied to land can be governed by several governmental agencies or legislative acts. These can be related to wastewater treatment levels, nutrient loading rates to land and the effects of aerosol mist from sprinkler irrigation. Evaporation of wastewater requires compliance with air quality regulations and where landfill gas is utilised, regulations require that all of the flammable gases are consumed in the process.
Industrial wastewater quality varies considerably depending upon the source. These waters can be derived as part of a process as in ethanol production, or as a by-product as in oil production, or as a result of cooling, or leachate from a landfill cell.
These waters are often complex, carrying organic compounds, salts and metals. Our science and engineering team analyzes the contents of these waters. They are capable of modelling various treatment methods to estimate their effectiveness.
Once we have an understanding of the various treatment options, they are analyzed from several perspectives. Often there are physical or logistical limitations that may limit treatment outcomes. Issues like limited power supply or proximity to environmentally sensitive areas may affect the choice of wastewater treatment.
The BeneTerra team looks for the best combination of technologies and management techniques to effectively deal with wastewater. These must meet be practical, meeting regulatory and budgetary requirements.
Our team has developed and implemented a variety of wastewater solutions. Some examples include:
- Amendment of coal water and distribution through drip irrigation
- Separation solids from drilling fluids so that water can be reused
- Evaporation of an ion exchange brine pond
- Reduction of landfill leachate volume
- Treatment of gas exploration pond water for road dust suppression
- Removal of fluoride from coal seam water to make it suitable for livestock consumption
