Packaged Treatment

A packaged treatment system is a water or wastewater treatment unit in which all process equipment, pipework, instrumentation and electrical components are assembled, integrated and tested on a structural skid frame at IWTE's fabrication facility before delivery to the installation site. The packaged approach transfers the majority of integration and commissioning work from the construction site to the controlled factory environment, resulting in faster on-site installation, higher build quality and a more reliable commissioning process compared to field-assembled systems.

IWTE supplies packaged systems for a wide range of treatment technologies including reverse osmosis desalination for both seawater and brackish water, ultrafiltration for pre-treatment and water purification, water softening and demineralisation using ion exchange, biological wastewater treatment using MBR or MBBR, chemical dosing suites for antiscalant, pH adjustment, coagulant and disinfectant dosing, UV and chlorination disinfection systems, and complete multi-stage high-purity water treatment trains. Any treatment process that can be self-contained within a practical skid footprint is available in packaged format.

A factory acceptance test (FAT) is a structured test conducted at IWTE's facility before a packaged system is dispatched to site, with the client's engineering or operations team invited to witness the test. The FAT confirms that all equipment is installed correctly, all instrumentation is calibrated, all process and safety control sequences operate as designed and the system performs to the specified design parameters under simulated operating conditions. Any issues identified during FAT are resolved before despatch, ensuring that site commissioning is efficient and the system performs correctly from the first day of operation.

Packaged systems are designed to minimise on-site civil and installation requirements. Typically, a concrete or steel plinth or frame to support the skid weight, a hardstanding area for outdoor units, and connections to inlet and outlet pipework, power supply and communications are all that is required. For indoor installations, the skid is positioned in a plant room or building and connected to site services. IWTE provides dimensional drawings, weight loads, connection schedules and foundation loading data at the design stage to support the civil design and ensure the installation is straightforward.

Yes. Packaged systems are well suited to temporary and emergency water supply applications, including disaster relief, construction site water supply, maintenance bypass during plant upgrades, population event water supply and emergency replacement of failed treatment equipment. The compact, self-contained format allows rapid mobilisation, with connection requiring only inlet, outlet, power and communications services. IWTE maintains a programme of standard packaged system designs that can be delivered on compressed timelines for urgent applications.

Yes. The packaged format is particularly well suited to remote and off-grid sites where skilled installation contractors are scarce, access for construction equipment is limited and the project programme does not permit extended site construction. IWTE designs packaged systems for solar power, diesel generator and hybrid power supply, with insulated and weather-protected enclosures available for hot, cold or humid climates. Systems for remote deployment are designed and tested for transportation by road, sea freight and airfreight where required.

IWTE designs packaged systems with modular expansion in mind. Additional skid modules of the same design can be connected in parallel to the existing installation using pre-engineered tie-in connections, increasing total capacity proportionally without modifying the existing unit. The PLC control system is designed to accommodate additional modules from the outset, with expansion provisions built into the control software and wiring. This allows capacity to be added in increments aligned with demand growth, without the capital cost of over-sizing the initial installation.

Yes. IWTE provides comprehensive operations and maintenance support for all packaged systems we supply, including site commissioning, operator training, operations and maintenance manuals, recommended spare parts lists and stocking guidance, scheduled service visits and remote technical support. For remote sites and systems operating without dedicated on-site operators, IWTE can provide remote monitoring and fault diagnosis via the PLC telemetry system, with IWTE engineers able to access system data and adjust operating parameters remotely.
