Operation & Maintenance (O&M)
Keeping water and wastewater treatment plants operating reliably, efficiently and consistently.
Reliable Treatment Requires Reliable Operation - Installed Plant to Sustained Performance
A well-designed treatment plant can only deliver consistent results when it is operated and maintained correctly.
Changes in feed-water quality, wastewater load, equipment condition, membrane performance, chemical dosing and operating practices can gradually affect treatment efficiency.
Hydroxy's O&M approach focuses on maintaining the complete plant—not simply repairing equipment when something fails. Operate correctly. Maintain proactively. Monitor continuously. Improve consistently.
Complete O&M Support - One Coordinated Approach to Plant Performance
Routine operation of treatment equipment according to defined process requirements and operating procedures.
Planned inspection and maintenance of pumps, blowers, membranes, filters, dosing systems, valves, instruments and electrical equipment.
Identification and rectification of equipment or process issues when abnormal conditions occur.
Monitoring important operating parameters and treated-water quality to identify changes before they become larger problems.
Monitoring chemical usage, filter media, cartridges, membrane requirements and other treatment consumables according to plant needs.
Recording operational data, maintenance activities, water-quality results and significant plant observations.
What Hydroxy Monitors - Know What Is Happening Inside the Plant
Depending on the treatment system, operational monitoring can include:
- Feed & Treated-Water Flow
- Pressure & Differential Pressure
- Tank Levels
- pH / ORP
- Conductivity / TDS
- Turbidity
- Dissolved Oxygen
- Residual Chlorine
- RO Permeate & Reject Flow
- Membrane Pressure
- Chemical Consumption
- Pump & Blower Operation
- Equipment Running Hours
- Sludge Generation
- Treated-Water Quality
Preventive Maintenance - Maintain Before Failure Interrupts Treatment
Preventive maintenance helps identify wear, fouling, abnormal vibration, leakage, pressure changes and other early indications of equipment deterioration. Typical O&M activities can include:
Inspection, alignment, seals, bearings and operating-condition checks.
Backwashing, pressure monitoring and media-condition assessment.
Performance monitoring, membrane cleaning and evaluation of fouling or scaling trends.
Operating checks, air-delivery assessment and routine maintenance.
Pump calibration, dosing-line inspection and chemical-consumption monitoring.
Sensor inspection, cleaning and calibration where required.
Control-panel inspection, alarms, interlocks, PLC/HMI operation and electrical connections.
O&M Is More Than Equipment Maintenance
A pump may be running correctly while the treatment process itself is performing poorly. Hydroxy therefore evaluates both equipment condition and process performance. Operational optimisation can include:
Reviewing feed, permeate and reject conditions to maintain appropriate membrane-system performance.
Optimising filtration and backwash cycles according to actual operating conditions.
Adjusting chemical addition according to water quality and treatment requirements.
Monitoring aeration, biological loading, sludge condition and relevant process parameters.
Identifying unnecessary pump, blower or equipment operation where practical.
Reviewing trends to help maintain the required treated-water performance.
Plants We Support

Ion-exchange and high-purity water-treatment systems.
Tertiary treatment and recovered-water systems.
Operational Visibility - From Daily Operation to Meaningful Information
Depending on the agreed O&M scope, Hydroxy can maintain operational records covering:
Clear operational reporting helps plant owners understand not only whether the plant is running—but how well it is performing over time.
Extending the Useful Life of the Plant - Protect the Investment After Commissioning
Poor operation can shorten the life of membranes, pumps, blowers, instrumentation and other treatment equipment. A structured O&M programme helps create a more disciplined approach to:
Routine inspection and upkeep of pumps, motors, blowers, valves, membranes, filters and other treatment equipment to maintain reliable operation.
Planned servicing and condition checks to identify wear, fouling or performance issues before they lead to equipment failure.
Tracking and planning requirements for chemicals, filter cartridges, membranes, resins and other consumables to avoid operational interruptions.
Early identification of equipment and process abnormalities to minimise unexpected failures, downtime and emergency repairs.
Regular monitoring of key water-quality parameters to verify that treated water continues to meet the required performance standards.
Reviewing operating conditions, chemical dosing, filtration cycles, membrane recovery and equipment performance to improve overall plant efficiency.
Hydroxy's Operation & Maintenance Approach
Keep the Plant Performing as a System. Hydroxy treats O&M as an ongoing combination of:
Controls and operating sequences that are practical for plant personnel.
The objective is not simply to keep machines running. It is to help maintain the treatment performance those machines were installed to deliver.
Reliable Plants Need Consistent Attention.
Water and wastewater treatment conditions change over time. Effective O&M helps identify those changes, maintain equipment condition and keep the treatment process aligned with operational requirements.
Hydroxy provides structured Operation & Maintenance support designed around the plant technology, capacity, operating conditions and required water quality.
