Seawater Intake Systems & Sea Outfalls

Elmosa
USA

Sseawater intake & Sea Outfall systems (CWIS) to supply clean water to electric power plants, desalination plants, seawater reverse osmosis plants, petroleum refineries, pulp & paper mills, fish and aquaculture farms, municipal water plants, and to discharge RO brine, cooling water, and wastewater.

Our Systems are designed for:
- Proaction rather than reaction
- Preservation rather than eradication of marine life,
- Prevention rather than curing

We also include anti biofouling injection system in the InvisiHead

The genuin InvisiHead and NaTsep technologies reside here


Seawater Intake & marine outfall System - the philosophy behind the design

The Elmosa offshore seawater intake and marine outfall systems - the InvisiHead velocity cap technology

We are seawater intake system consultants as well as InvisiHead designers and fabricators.

outfall

For the proper design of the seawater intake and outfall, the InvisiHead system has been developed to be the system that naturally handles the flows in both directions. The InvisiHead seawater intake velocity cap is selected by the US Environmental Protection Agency consultants as the best technology available (BTA or BAT). It is in full compliance with the requirements of Section 316(b) of the US EPA Clean Water Act. It meets and exceeds the requirements by 40%. The Act requires the entrance velocity not to exceed 0.15 m/s, The InvisiHead's is 0.09 m/s. The InvisiHead is for the preservation of biodiversity and for the protection of the ecosystem, the variety of life on Earth.

The InvisiHead system works as a superb marine outfall. The dispersion process of effluents is unmatched by any other technology including the widely-used linear riser - diffuser systems. Dilution occurs within a short distance from the pointsource.

Flow velocities into the InvisiHead intake head and out of the InvisiHead outfall:

0.0025 m/s max. (0.009 fps) <5 meters (15 ft) away from entrance, approaching or exit leaving,
0.03 m/s max. (0.1 fps) 1.0 meter (3 ft) away from entrance, approaching or exit leaving,
0.09 m/s max. (0.3 fps) at entrance, entering or releasing.

Headloss at the InvisiHead approaches zero. It is engineered to control and drastically reduce the inflow of debris, the ingress of fish, and the impingement of mussels and other marine life and entrained air.
