Growing Flow
The facility now produces more wastewater than the original plant was designed to treat.

CAPACITY WITHOUT STARTING OVERYour existing plant
Your existing plant
may still have
something to give.
An overloaded plant does not automatically mean a completely new plant.
Existing tanks, structures, pipelines and equipment may still be useful. The real question is where the treatment bottleneck sits and how much of the current infrastructure can continue to work.
Nitaneer approaches capacity upgrades by first understanding the existing system, then adding or modifying only the treatment stages that actually need it.
Plants change.
Loads change.
Treatment systems are often asked to handle conditions very different from those they were originally designed for.
Poor Performance
The existing treatment process struggles to consistently achieve the required treated-water quality.
Ageing Equipment
Pumps, aeration systems, mechanical equipment or treatment stages have become inefficient or unreliable.
Limited Space
There is insufficient land for a completely new conventional treatment plant.
Reuse Requirement
The project needs improved polishing or tertiary treatment so more treated water can be reused.
Changing Compliance
Operational or discharge requirements have changed since the original system was commissioned.
Improve what exists.
Add only what is needed.
The correct strategy depends on the physical condition of the existing plant, available space, wastewater characteristics and additional capacity required.
Parallel Module
A separate treatment module can be installed alongside the existing plant to handle additional wastewater without making the new capacity completely dependent on the old process.
BEST FITPlants that are operating but need additional treatment capacity.
Plant Rehabilitation
Existing tanks, equipment and process stages are assessed for reuse while ageing or underperforming components are rehabilitated, replaced or supplemented with new treatment capacity.
BEST FITOlder, inefficient or non-performing STP and ETP installations.
Process Integration
New treatment stages can be integrated into usable existing infrastructure to improve biological performance, solids handling, polishing or hydraulic capacity with targeted modifications.
BEST FITStructurally usable plants that need better performance or additional capacity.
PARALLEL CAPACITYAdd capacity
Add capacity
beside the plant.
A new treatment module can operate alongside the existing plant.
Incoming wastewater can be divided between the existing system and an additional packaged treatment module. This approach can be useful where the current plant remains operational but no longer has enough hydraulic or biological capacity.

Keep the structure.
Upgrade the process.
Older treatment plants can suffer from worn equipment, poor aeration, inefficient biological performance, inadequate solids separation or outdated polishing systems.
Where existing infrastructure remains usable, rehabilitation can combine repairs with new process equipment to restore performance and increase practical capacity.

Fix the bottleneck.
Sometimes the entire treatment plant is not the problem.
A structurally sound system may be limited by one stage — aeration, biomass retention, solids separation, filtration, hydraulic transfer or disinfection.
Targeted integration allows the upgrade to focus on that limiting process instead of replacing usable infrastructure.

EXISTING PLANT REVIEW
Existing Plant Review
We review the current process, treatment stages, tanks, equipment and operating condition.
FLOW & LOAD ASSESSMENT
Flow & Load Assessment
Actual and expected wastewater flow, organic load and operating patterns are studied.
PERFORMANCE DIAGNOSIS
Performance Diagnosis
The bottleneck is identified — biological capacity, aeration, clarification, hydraulics, filtration, disinfection or equipment.
UPGRADE STRATEGY
Upgrade Strategy
The practical route is selected: parallel capacity, rehabilitation, targeted integration or a combination.
IMPLEMENTATION
Implementation
New equipment and process modifications are integrated around the existing plant with disruption considered during engineering.

Upgrade the plant.
Not the problem.
Capacity expansion should not simply add more equipment to an already inefficient system.
The objective is to understand what can remain, what must change and where new treatment capacity creates the greatest practical improvement.
