Checklist 4: Membrane Systems

 

1. Pretreatment

☐ Pretreatment provided
Raw water is conditioned to reduce solids, organics, and fouling load (e.g. filtration, coagulation, carbon treatment), protecting the membranes and extending lifespan.

2. Cleaning Strategy

☐ Cleaning strategy defined
Regular cleaning intervals, chemicals, and performance targets are defined to prevent fouling and maintain capacity.

3. Energy Demand

☐ Energy demand calculated
Operating pressure, pumping needs, and total energy consumption (especially for NF/RO) are assessed for long-term feasibility.

4. Membrane Replacement

☐ Replacement membranes available
Service life, spare membranes, and replacement planning are defined to avoid downtime and ensure continuity.

5. Concentrate Management

☐ Concentrate disposal addressed
Disposal or reuse of reject water (NF/RO) is planned during design (e.g. wastewater, discharge, reuse options).

6. Operator Training

☐ Operators trained
Staff are trained in operation, cleaning, monitoring, and troubleshooting to ensure stable system performance.

7. Monitoring

☐ Monitoring system installed
Key parameters such as pressure, flow, permeability, recovery, and water quality are continuously monitored.

8. Maintenance Plan

☐ Maintenance plan available
Preventive maintenance includes inspections, cleaning, calibration, and spare parts management.
