t Operating &Support (O&S) = Net Present Value (estimated using 20-year Service Life at 5% Discount Rate) of all prescribed maintenance, parts, component replacement and consumables.
Real Time Effluent Monitoring
Effluent quality is continuously monitored through automatic measurement of effluent quality if, as in the case of system upset, effluent is outside of prescribed parameters, the system continues to process until effluent of acceptable quality is produced. Treated water is then either pumped directly overboard, or pumped to onboard ship storage tanks for eventual discharge ( i.e. ship operations in no discharge zones).
Fully Programmable Automation
All Navalis Poseidon® Systems are fully automated using an Allen-Bradley Programmable Logic Controller (PLC). The PLC is equipped with modem or ethernet internet connectivity for reach-back monitoring of off ship system performance. This enables Navalis specialists to ensure continued reliable service of the system and predict and trouble shoot operational issues.
Quality Craftsmanship & Simple Installation
Navalis adheres to an ease of installation philosophy resulting in each component fitting through standard ship door and hatch sizes for ease of rigging to the designated system compartment. The arrangement allows for easy access to areas requiring routine maintenance. Navalis has designed the Poseidon System for continuous operation with a minimum number of moving parts to minimize maintenance costs. The Navalis Poseidon® Systems are crafted of the finest materials by the finest craftsmen and are ready for long service. Most components are constructed from 316L Stainless Steel, affording long life to system components.
The Navalis Modular Design
Inherent in the Navalis Poseidon® System design is modularity. The expandable building block nature of the system enables assembly of many system treatment sizes from a standard family of 24-inch and 36-inch diameter tanks. System treatment capacity is a function of the number of modular system components selected. The modular design of the Navalis Poseidon® System has the added advantage of creating various configurations to optimize available space. The Navalis Poseidon® System is designed for growth. The modular nature of its components enables ease of expansion. For example, the capacity of the 25-gpm graywater system could easily be increased by adding a filter module, and if necessary an additional reactor. Navalis Poseidon® System components are mounted on standard sized stainless steel squares that facilitate ease of mounting on ships foundations and create the possibility for variable configurations; from a very compact square to open linear. The 10-gpm blackwater and 25-gpm graywater systems share reactor and tank designs. Components are mounted on 28-inch stainless steel squares affording access through 40-inch (1 meter) openings. The 20-gpm blackwater and 100-gpm graywater systems share reactor and tank designs and are mounted on 40-inch stainless steel squares, allowing access through 57-inch (1.5 meter) openings.
