01
Complex effluent
Effluent that can contain dissolved contaminants, solids and process chemicals.
Water & wastewater engineering forChemical Industry
Treatment pathways developed around complex industrial effluent.
From physico-chemical and biological treatment to membranes and recovery.
Understanding the application
Complex effluent needs a treatment path built around its chemistry.
Chemical manufacturing can produce effluent with a wide range of dissolved contaminants, solids and process chemicals.
Its characteristics may change between products, batches and campaigns — so a treatment train has to be selected from characterisation, not assumption.
We combine physico-chemical, biological and membrane stages into a pathway suited to the effluent and its discharge or reuse requirement.
The water challenge
Conditions that shape the treatment path.
Treatment starts with the actual water, wastewater and operating context. These are the typical considerations our engineers assess for chemical applications.
02
Variability
Characteristics that may change between products, batches and campaigns.
03
Treatability
Treatment stages selected through characterisation, not assumption.
04
Recovery and discharge
Meeting the discharge standard, with recovery where technically appropriate.
Our water & wastewater focus
Engineering around the requirement.
The final treatment train depends on characterisation, site constraints and the required discharge or reuse quality.

Before the first conversation
What to prepare before discussing treatment.
None of this is required to start. The more of it is available, the faster a chemical requirement can move from conversation to an engineering basis.
- 01
Which products and processes generate effluent, and whether high-strength or difficult streams are segregated.
- 02
Analysis of the key constituents — pH, dissolved solids, organic load and any specific chemicals of concern.
- 03
Whether discharge is batch or continuous, and how much it varies.
- 04
The discharge or reuse criteria applicable to the site.
- 05
Whether recovery or zero liquid discharge is required or being considered.
- 06
Existing treatment and the problems it currently has.
