At Mueller Water, we specialize in marine-grade water purification solutions, including reverse osmosis desalination, ultrafiltration, and water conditioning technologies. Our systems deliver high-quality freshwater while reducing scaling, corrosion, and biofouling, ensuring operational efficiency and regulatory compliance in maritime applications.

Importance of Water Treatment in Marine Applications

Freshwater is a limited and valuable resource at sea. Without proper treatment, ships and offshore facilities face:

• Reliance on expensive freshwater resupply from port facilities.
• Corrosion and scaling in engines, boilers, and cooling systems due to high salt content.
• Biofouling and bacterial growth in potable water storage tanks.
• Regulatory challenges for wastewater discharge and environmental protection.

With advanced water treatment technologies, marine vessels and offshore operations can produce high-quality freshwater, reduce maintenance costs, and comply with maritime regulations.

Water Treatment Technologies for Marine Applications

Mueller Water offers cutting-edge water treatment systems tailored for ships, offshore rigs, and marine operations:

1. Reverse Osmosis (RO) Seawater Desalination

• Converts seawater into potable water using high-pressure membranes.
• Removes salt, bacteria, and contaminants, ensuring compliance with drinking water standards.
• Example: A commercial fishing vessel in the Gulf of Mexico installed an RO desalination system, reducing freshwater resupply costs by 50% and increasing operational autonomy.

2. Ultrafiltration (UF) & Media Filtration

• Removes sediments, silt, and biological contaminants from seawater and onboard freshwater storage.
• Enhances pre-treatment for reverse osmosis systems, extending membrane lifespan.
• Example: A luxury cruise ship implemented ultrafiltration pre-treatment, reducing RO membrane replacement costs by 40%.

3. UV Water Sterilization & Disinfection

• Uses ultraviolet light to neutralize bacteria, viruses, and pathogens in potable water.
• Provides chemical-free disinfection, preventing biofouling in storage tanks and distribution lines.
• Example: A naval vessel installed UV disinfection, ensuring pathogen-free water supply for crew members.

4. Water Softening & Anti-Scaling Solutions

• Prevents hard water scale buildup in boilers, heat exchangers, and cooling systems.
• Extends the lifespan of marine engines, desalination units, and onboard piping.
• Example: An offshore oil rig used a water softening system, reducing heat exchanger scaling by 70%, minimizing downtime.

5. Wastewater & Bilge Water Treatment Systems

• Treats greywater and bilge water to meet IMO and MARPOL discharge regulations.
• Prevents pollution and ensures compliance with environmental laws.
• Example: A cargo vessel installed a bilge water treatment system, achieving full compliance with MARPOL Annex I regulations.

Benefits of Water Treatment in Marine Environments

1. Reduced Dependence on Shore-Based Freshwater Supplies

• Onboard desalination systems eliminate the need for costly freshwater resupply.
• Ensures continuous water availability for drinking, cooking, and operations.

2. Corrosion & Scaling Prevention in Ship Systems

• High-quality water reduces damage to boilers, cooling towers, and onboard plumbing.
• Extends the lifespan of ship equipment, lowering maintenance costs.

3. Compliance with Maritime Regulations

• Ensures adherence to IMO, USCG, and MARPOL water discharge and purification standards.
• Prevents environmental violations and costly fines.

4. Improved Crew & Passenger Health

• Provides safe, contaminant-free drinking water for ship personnel and guests.
• Reduces the risk of waterborne diseases and bacterial outbreaks.

The Risks of Untreated Water in Marine Applications

Without proper water treatment, marine vessels and offshore operations face:

• Saltwater Corrosion – Seawater contaminants accelerate metal degradation, rust, and equipment failure.
• Biofouling in Water Tanks – Bacteria and algae growth contaminate drinking water supplies and distribution lines.
• High Maintenance Costs – Scale buildup and sediment deposits reduce efficiency in engines, boilers, and RO membranes.
• Regulatory Non-Compliance – Untreated wastewater discharge violates environmental laws, leading to fines and operational restrictions.

Case Study: Reverse Osmosis Desalination on a Cruise Ship

The Problem:

A cruise liner operating in the Caribbean faced high freshwater resupply costs and frequent corrosion issues in its cooling systems due to poor water quality.

The Solution:

The vessel installed a custom-designed reverse osmosis (RO) desalination system with:

• Pre-treatment filtration to remove silt and organic debris.
• High-pressure RO membranes to convert seawater into potable water.
• Post-treatment remineralization to optimize water quality for drinking and cooking.

The Results:

• Eliminated dependency on freshwater resupply, reducing operational costs.
• Improved cooling system efficiency, preventing scale and corrosion damage.
• Ensured high-quality potable water for passengers and crew, enhancing onboard safety.
