Marine & Coastal Engineering

Seawater Intake and Outfalls

The design and selection of seawater intake and outfall systems are crucial, not only for the optimization of pretreatment and overall plant performance, but also for lowering the whole-life cost of water production.

The design challenges range from advanced hydraulic engineering to rigorous marine environmental protection. Success in delivering these projects involves deep expertise in process plant requirements, marine bathymetry, sediment transport, and environmental impact mitigation.

For common intake systems, site selection and marine assessment are essential to identify the degree and type of pretreatment required — particularly regarding suspended solids, debris, biological matters, pollutants, and residual heavy metals. Protec Pacific integrates intake structures, velocity caps, and pipeline hydraulics as one cohesive system.

Industrial Process Engineering

Sand Washing & Aggregate Processing

PROTEC is actively engaged in process integrations and provisions of specialized industrial technologies. One major sector we serve is the construction aggregate industry, where sand washing and water recovery demands have grown rapidly.

Sand washing plants are composed of multiple integrated unit operations. Typically, stone material is fed to jaw crushers to achieve target sizes, separated by vibrating screens, and conveyed to sand-making units. The suitable sand material is then processed through high-efficiency sand washing machinery to be thoroughly cleaned and desilted.

Our engineering focus centers on closed-loop wash water clarification and tailings dewatering, ensuring over 90% of process water is recycled back to the washing circuit, drastically reducing freshwater intake and pond footprint.

Pumping & Hydraulic Systems

Package Pump Stations

Package pump stations are factory-designed, pre-assembled, and rigorously tested pump systems tailored to client specifications. They offer major advantages as mechanical, piping, and electrical components are integrated in controlled factory conditions, eliminating site commissioning delays.

Applications include municipal sewage lifting, domestic pressure boosting, industrial fluid transfer, fire fighting, HVAC circuits, and agricultural irrigation. With optimized wet-well hydraulics and intelligent variable speed drives, these stations achieve peak hydraulic efficiency in a significantly smaller physical footprint.

Design advancements and smart PLC automation deliver substantial energy savings and predictive maintenance telemetry to plant operators throughout the system lifecycle.
