Upgrade Your Existing ETP Instead of Starting From Zero
Industrial wastewater flow and pollution load can change over time. Production expansion, additional shifts, new manufacturing processes or stricter treated water requirements can make an existing ETP insufficient.
In such situations, complete replacement of the plant may not always be necessary. The existing tanks, equipment and infrastructure can be technically assessed to determine what can be retained, modified, upgraded or replaced.
RRR ENVIRO SYSTEMS provides ETP capacity enhancement, process modification and technology conversion based on site conditions, wastewater characteristics, design requirements and technical feasibility.
What We Evaluate Before Upgrade
- ✓ Existing wastewater flow
- ✓ Peak hydraulic flow
- ✓ pH, BOD, COD & TSS
- ✓ Oil & Grease / specific pollutants
- ✓ Existing tank volumes
- ✓ Hydraulic Retention Time (HRT)
- ✓ Existing MLSS / biological loading
- ✓ Blower & oxygen requirement
- ✓ Pump capacity & head
- ✓ Clarifier loading
- ✓ Sludge handling capacity
- ✓ Electrical & automation system
Example: Existing 10 KLD ETP → 30 KLD
A capacity upgrade is not simply a matter of increasing the nameplate capacity. Existing hydraulic, biological, mechanical, electrical and civil components must be checked before deciding the upgrade configuration.

How We Upgrade Existing ETP Capacity
The final upgrade design is determined after reviewing actual wastewater flow, characteristics, existing equipment and site conditions.
Flow Assessment
Review average flow, peak flow, operating hours and future production requirements.
Wastewater Analysis
Review parameters such as pH, BOD, COD, TSS, oil & grease and process-specific pollutants.
Hydraulic Review
Check tank volume, HRT, hydraulic loading, pipe sizes, pumps and overflow arrangements.
Biological Review
Review organic loading, MLSS, F/M ratio, oxygen demand and aeration capacity.
Equipment Review
Check blowers, pumps, mixers, agitators, diffusers, filters and other equipment.
Clarifier Review
Check surface overflow rate, solids loading, sludge withdrawal and settling performance.
Electrical Review
Check connected load, MCC panels, cables, starters, VFDs and automation requirements.
Final Upgrade Design
Prepare the suitable modification, equipment replacement and commissioning plan.
ASP → MBBR Conversion
Existing Activated Sludge Process systems can be evaluated for conversion to Moving Bed Biofilm Reactor technology where technically suitable.
Existing ASP System
- Suspended growth biological process
- Aeration tank
- MLSS-based biological treatment
- Return Activated Sludge arrangement
- Secondary clarification
- Existing blower & diffuser system
MBBR Upgrade
- Attached-growth biological process
- MBBR carrier media
- Media filling percentage calculation
- Media retention screens
- Aeration & mixing requirement
- Secondary clarification review
MBBR Media Selection
Media type, protected surface area, filling percentage and required biological capacity are evaluated.
Aeration Requirement
Existing blower capacity, oxygen requirement, air distribution and diffuser condition are reviewed.
Media Retention
Suitable outlet screens or media retention arrangements are required to prevent carrier loss from the reactor.
MBBR → MBR Conversion
For applications requiring higher treated water quality and compact biological treatment, an existing biological system may be evaluated for MBR conversion.
Existing MBBR System
- MBBR biological reactor
- Carrier media
- Aeration system
- Secondary clarification
- Sludge handling
- Treated water outlet
MBR System
- Biological reactor
- Membrane separation
- Fine screening requirement
- Membrane air scour
- Permeate pumping
- CIP / membrane cleaning
Membrane Area Calculation
Membrane area is selected based on design flow, peak flow, membrane flux and required operating conditions.
Air Scour System
Membrane air scour requirement and blower capacity must be considered during MBR design.
Membrane Protection
Fine screening and suitable pretreatment are important to protect membrane modules from unwanted solids.
Permeate System
Permeate pump, suction arrangement, pressure monitoring and treated water transfer are evaluated.
CIP System
Chemical cleaning arrangement is considered according to membrane manufacturer requirements.
TMP Monitoring
Transmembrane pressure and membrane performance monitoring can be incorporated into the upgraded system.
Other ETP Technology Conversion & Improvement
Existing treatment systems can be evaluated for process improvement according to wastewater characteristics and required treated water quality.
Chemical Treatment Upgrade
Coagulation, flocculation, chemical dosing and clarification systems can be reviewed and improved.
Aeration System Upgrade
Blower, diffuser, air header and oxygen transfer requirements can be evaluated.
Tertiary Treatment Upgrade
Filtration and polishing systems can be added or modified according to treated water requirements.
Water Reuse Upgrade
Existing treated water systems can be evaluated for suitable reuse applications.
Sludge Management Upgrade
Sludge withdrawal, holding, dewatering and handling systems can be improved where required.
Automation Upgrade
Electrical panels, VFDs, instrumentation and control systems can be upgraded.
Complete ETP Upgrade – Civil, MSEP & Turnkey Works
RRR ENVIRO SYSTEMS can undertake suitable complete ETP upgrade and revamping scopes including civil work, MSEP/MS tank fabrication or modification, mechanical equipment, piping, electrical work and commissioning, based on project requirements.
When Should an Existing ETP Be Upgraded?
Production Expansion
Production has increased and the existing ETP is unable to handle the additional wastewater flow.
Higher Wastewater Flow
Existing plant capacity is lower than current or future wastewater generation.
Changed Wastewater Characteristics
New production processes have changed the pollution load or wastewater characteristics.
Poor Treatment Performance
The existing plant is not consistently achieving required treated water parameters.
Old Equipment
Ageing pumps, blowers, panels, diffusers or other equipment require replacement.
Water Reuse Requirement
Higher quality treated water is required for suitable reuse applications.

ETP Upgrade & Revamping – Frequently Asked Questions
Can an existing 10 KLD ETP be upgraded to 30 KLD?
Yes, an existing 10 KLD ETP can be evaluated for upgrade towards 30 KLD. However, the existing tanks, hydraulic capacity, biological treatment, blowers, pumps, clarifier, filters, piping and electrical systems must be assessed before finalizing the upgrade design.
Can you convert an existing ASP plant to MBBR?
An existing ASP system can be evaluated for conversion to MBBR where technically suitable. The evaluation may include MBBR media loading, reactor volume, aeration requirement, diffuser arrangement, media retention screens, biological loading and clarification system.
Can an existing MBBR plant be converted to MBR?
Yes, an existing MBBR plant can be evaluated for MBR conversion. The upgraded system may require membrane modules, fine screening, membrane tank arrangement, air scour, permeate pumping, membrane cleaning and suitable instrumentation.
Will all existing ETP equipment be reused after upgrading?
Not necessarily. Each existing component is assessed for capacity, condition and compatibility. Suitable equipment may be retained, modified, upgraded or replaced depending on the final design.
Do you undertake civil work during ETP revamping?
Suitable civil modification, repair and construction work can be included in ETP upgrade and revamping projects depending on site requirements.
Do you modify or fabricate MSEP / MS ETP tanks?
Suitable MSEP/MS tank fabrication, modification, replacement and related work can be included based on the project requirement and site condition.
