Annual Maintenance Contract (AMC)
Planned maintenance for reliable water-treatment performance throughout the year.
Protect Your Water Treatment Investment - Maintenance Should Be Planned, Not Reactive
Successful water infrastructure requires more than selecting treatment equipment.
Water-treatment equipment operates continuously under changing water quality, pressure, chemical and environmental conditions.
Without regular inspection and maintenance, small issues such as membrane fouling, pump wear, clogged filters, dosing variation, sensor drift or valve problems can gradually affect plant performance.
Hydroxy AMC programmes provide a structured maintenance schedule designed around the equipment, operating conditions and service requirements of the plant.
Inspect regularly. Maintain proactively. Reduce unexpected failures.
What an AMC Can Include - Scheduled Support Throughout the Contract Period
Periodic inspection and servicing of treatment equipment according to an agreed maintenance schedule.
Review of pumps, motors, blowers, filters, membranes, pressure vessels, valves, dosing systems and associated equipment.
Assessment of important operating parameters to identify deterioration in treatment performance.
Checking sensors, gauges, transmitters, controllers and other monitoring equipment for correct operation.
Inspection of control panels, PLC/HMI systems, motor controls, alarms and equipment interlocks.
Technical assistance for equipment faults occurring during the AMC period, according to the agreed contract scope.
Service records documenting inspections, observations, maintenance performed and recommended corrective actions.
Preventive Maintenance - Identify Problems Before They Become Breakdowns
A structured preventive-maintenance programme can help detect early signs of:
Unusual noise, vibration, leakage or changes in operating performance.
Changes in pressure, permeate flow, recovery or treated-water quality.
Increasing differential pressure, reduced flow or ineffective backwashing.
Blocked lines, calibration changes, pump wear or inconsistent chemical delivery.
Sensors or analysers providing inaccurate process information.
Leakage, poor actuation or deterioration that can affect treatment operation.
Finding these conditions early can help reduce emergency repairs and unplanned downtime.
Equipment Covered - Maintenance Across the Complete Treatment System
Depending on the plant and AMC scope, Hydroxy can support:
Raw-water treatment, drinking-water and industrial process-water systems.
RO membranes, pumps, dosing systems, instrumentation and associated pretreatment.
Pressure sand filters, multimedia filters, activated-carbon filters and specialised filtration systems.
Water softeners, DM plants, mixed-bed systems and associated valves and regeneration equipment.
STP, ETP, MBBR, SBR, MBR and tertiary-treatment equipment.
UV, chlorination, ozonation and associated dosing or monitoring equipment.
Transfer pumps, high-pressure pumps, booster systems and chemical metering pumps.
Flow, pressure, level and water-quality instruments, control panels, PLCs and HMIs.
Maintenance Should Protect Treatment Performance
An AMC should look beyond whether equipment simply switches on and off. Depending on the system, Hydroxy can review parameters such as:
- Flow Rate
- Operating Pressure
- Differential Pressure
- RO Feed / Permeate / Reject
- Conductivity / TDS
- pH
- Turbidity
- Chemical Dosing
- Pump Performance
- Membrane Condition
- Filter Performance
- Tank Levels
- Instrument Status
- Alarm & Interlock Operation
The objective is to identify changes that may indicate equipment deterioration, fouling, inefficient operation or maintenance requirements.
