How It Works
Sewage treatment uses a series of physical, biological and chemical processes to progressively remove solids, organic contaminants, nutrients and pathogens from wastewater, producing effluent suitable for safe discharge or reuse.
1-Preliminary & Primary Treatment
Screens and grit removal systems capture large debris, while primary clarifiers allow heavy solids to settle and lighter oils and scum to rise for removal. This prepares the wastewater for deeper treatment and protects downstream equipment.
2-Secondary (Biological) Treatment
Microorganisms biologically degrade dissolved organic matter using processes such as activated sludge, sequencing batch reactors (SBR), trickling filters or moving-bed biofilm reactors (MBBR), reducing biochemical oxygen demand (BOD) and chemical oxygen demand (COD).
3-Tertiary Treatment & Polishing
Advanced processes remove residual suspended solids, nutrients and pathogens. These may include filtration, chemical precipitation, nutrient removal, disinfection (e.g., UV or ozone), or membrane filtration to achieve high effluent quality.
4-Sludge Handling & Dewatering
Sludge generated during treatment is thickened, dewatered and stabilised using belt presses, centrifuges or other dewatering technologies to reduce volume for safe disposal or reuse.

Core System Components
AquipTec’s sewage treatment systems integrate proven technologies selected and configured to meet site-specific wastewater profiles, effluent standards and operational goals.
Screening & Grit Removal
Mechanical screens and grit chambers protect downstream treatment equipment and remove debris, sand and grit. These components include coarse and fine screens, rakes and grit traps with automated extraction systems.
Primary Clarifiers & Oil Separation
Primary treatment units use gravity to settle solids and float oils/grease. Components include clarifier tanks, skimmer mechanisms, sludge hoppers and oil interceptors to reduce solids load for biological stages.
Biological Treatment Modules
Biological processes break down organic contaminants:
• Activated Sludge Reactors (ASR) with aeration and settling tanks
• MBBR Units with biofilm carriers
• SBR Systems with controlled fill-aerate-settle phases
• Trickling Filters with fixed media for attached growth
These systems are monitored and controlled for dissolved oxygen, solids recycling and optimal biomass activity.
Tertiary Polishing & Disinfection
Advanced polishing may use sand or membrane filters, biological nutrient removal, chemical precipitation for phosphorus capture, and disinfection via UV or ozone to achieve regulated effluent quality.
Sludge Treatment & Dewatering Modules
Sludge produced in primary and secondary stages is thickened, conditioned and dewatered using technologies such as belt filter presses, centrifuges or screw presses. Polymer dosing, conditioning tanks and sludge conveyors support efficient dewatering.
Control & Automation Systems
Integrated PLC/SCADA systems monitor pH, flow, dissolved oxygen, nutrient levels and other key parameters, providing automated control, data logging and remote access for consistent performance.

Frequently Asked Questions (FAQ)
What is sewage treatment?
Sewage treatment removes contaminants from wastewater through primary, secondary and tertiary processes to produce safe effluent.
What effluent quality can be achieved?
Treated water can meet stringent discharge limits or be suitable for reuse in non-potable applications depending on treatment configuration.
Can systems be modular or containerised?
Yes, modular and containerised options allow fast deployment and scalable capacity for remote or temporary sites.
How is sludge managed?
Sludge is thickened, dewatered and stabilised to reduce volume and facilitate safe disposal or reuse.
