Clients are able to purchase a full range of waste, wastewater, and water management systems from Evac to simplify coordination and integration during projects. The Evac Complete Cleantech Solution covers a variety of requirements, including vacuum collection and wastewater treatment, as well as fresh water generation, wet, dry, and food waste management, and fresh water generation. This comprehensive offering is what sets Evac apart from the competition.

Vacuum collection systems

Vacuum collection units collect condensation, sewage and food waste by pumping it into a collection tank or sewage treatment plant.

Since the 1970s, Evac has developed a wide range of vacuum collection systems, including water-saving vacuum toilets, food waste collection units, and vacuum and collection units for condensation, which are typically used in conjunction with cooling equipment both at sea and on land.

Wastewater treatment systems

Wastewater treatment systems separate and neutralize organic contaminants in wastewater in compliance with national and international legislation. Evac’s products include electrolytic and wastewater treatment plants that refine gray and black water, as well as systems for separating grease from kitchen and galley wastewater.

Our moving bed biofilm reactors (MBBRs) and advanced membrane bioreactors (MBRs) are biological sewage treatment plants. MBBRs are mainly suitable for large cruise vessels, while MBRs are suitable for a wide range of vessels. Both systems offer nutrient removal. Our electrolytic wastewater treatment plants can be used on a variety of vessel types, but are especially suitable for naval applications, offshore vessels, and platforms.

Dry and wet waste treatment

Evac’s wet and dry waste systems manage recyclable or mixed waste via safe, environmentally friendly and energy efficient methods, reducing the volume through compaction, shredding, and burning.

Our portfolio includes bio sludge treatment units, incinerators, dryers, waste briquetting systems, waste compaction equipment and food waste treatment units that offer cost-effective installation and maintenance. Fresh water generation

Fresh water generation systems convert seawater into process, service, and drinking water. The equipment also filters, disinfects and adjusts the hardness of water, as well as mineralizes fresh water . Evac provides seawater desalination units using reverse osmosis (RO), as well as potable water treatment systems that provide disinfection and mineralization. Evac offers products that suit the requirements of passenger, merchant, and naval ships and offshore facilities.

RO desalination units are economical and energy efficient, especially compared to evaporators. If energy recovery systems are used, even higher energy efficiency can be achieved, leading to a shorter amortization time.

Automated systems for waste treatment and fresh water generation

Our integrated vacuum collection, dry and wet waste treatment, wastewater treatment and fresh water generation systems feature touchscreen panels for easy control. Evac systems have a similar user interface, making operation, maintenance and supervision easy and quick to learn.

The main automation system has all the systems on one interface to allow remote programming. Supervision and diagnostics are easier, with real-time information on all systems available in one place. The systems use the same parts, reducing storage and inventory costs, and are modular, meaning that new units can be added or removed when required.
