Aerobic biological
Used where biodegradable organics can be treated with aeration and a stable biomass.
Effluent Treatment Plants
Industrial ETP solutions begin with the effluent
Industrial wastewater changes with raw materials, processes, production schedules and cleaning practices. Hitech Fluid Systems engineers ETPs around the actual effluent and the required outcome.
Site-specific effluent
Different effluent, different treatment
Industrial wastewater contains chemicals and toxins in varying forms and must be treated before discharge or reuse. Hitech Fluid Systems specialises in effluent treatment — different processes for different streams. The train may combine mechanical, biological and physio-chemical steps.
For biological treatment we may use conventional processes or high-performance reactors, including anaerobic UASB where it fits. Activated sludge, lamella clarification and membrane processes can be considered for reuse or tighter discharge. The design is based on analysis, not a generic industry label.
What an ETP must account for
- Effluent sources and variability across shifts
- Flow, peak loads and existing collection systems
- Inlet characteristics from appropriate testing
- Required treated-water quality and any reuse
- Sludge handling, footprint and operating capability
- Current plant constraints and future production changes
- Cleaning chemicals and campaign production
- Energy, chemicals and operator skill available on site
Process options
Aerobic, anaerobic and physio-chemical stages
Anaerobic biological
Considered for higher-strength streams, including space-saving high-performance reactors such as UASB where suitable.
Physio-chemical
Coagulation, flocculation, clarification and related stages for suspended solids, colour, oil or other constituents that biology alone will not remove.
A practical engineering process
- Assess the facility, production process and wastewater streams
- Arrange analysis through external laboratory partners where needed
- Define the treatment objective and capacity
- Engineer the sequence, equipment and sludge route
- Install, integrate and commission the agreed scope
- Support through AMC, O&M, troubleshooting or revamping
Project experience includes an ETP solution for The Sanmar Group. Fuller case notes are published as capacity, process and outcomes are confirmed.

Existing ETP underperforming?
A plant may struggle because the effluent changed, loading increased, equipment aged or the process is not being operated as intended. Hitech Fluid Systems can investigate ETPs installed by other companies before recommending replacement or an upgrade.
Frequently asked questions
How is an ETP different from an STP?
An ETP treats industrial process effluent, while an STP generally treats domestic sewage. Their designs follow the characteristics of the wastewater and the intended outcome.
Can treated effluent be reused?
Potentially, after a suitable process is designed and the resulting water is shown to meet the intended reuse requirement.
Can an existing ETP be upgraded?
Often it can be assessed for process, capacity or equipment improvements. The technically appropriate route depends on the existing plant.
