Alfa Laval PureBallast 3 Ultra

Introduction

Alfa Laval PureBallast 3 Ultra is the latest ballast water

management system built on proven PureBallast 3

technology. Offering increased performance in challenging

waters and even easier installation, it can be configured for

ballast water flows of 42–3000 m3/h, as well as Ex

requirements.

PureBallast 3 Ultra treats ballast water without chemicals,

combining high-performance filtration with enhanced UV

treatment. In the UV reactor(s), specially designed synthetic

quartz lamp sleeves transmit an extended wavelength

spectrum that provides more UV light. Together with the

internal reactor design, this ensures optimal UV dosage with

very low energy consumption. An expanded range of reactor

sizes further reduces power needs in specific configurations.

Application

PureBallast 3 Ultra is a modular, inline system for the

biological disinfection of ballast water. Using PureBallast 3

technology that has been type approved by IMO and the U.S.

Coast Guard (USCG), it removes organisms in accordance

with set limits.

PureBallast 3 Ultra can be used in all water types – fresh,

brackish or marine. With its enhanced UV treatment, it also

provides unmatched disinfection performance in low-clarity

water. Moreover, its upgraded filter design provides greater

protection against clogging.

PureBallast 3 Ultra uses the same treatment technology as

type-approved PureBallast 3 systems. Updated type

approvals are in progress due to the new configurations.

Benefits

• Superior Performance in any waters and challenging

conditions

• Minimized power consumption

• Easy installation with minimized footprint

• Delivered Connectivity-ready

• Designed and supported for the whole vessel lifetime

Superior Performance in any waters and challenging

conditions

PureBallast 3 Ultra offers unmatched biological disinfection

performance in any type of water: fresh, brackish or marine.

This includes liquid water at sub-zero temperatures. When

operating in IMO-regulated areas with brackish or marine

water, it maintains full flow where the UV transmittance is as

low as 42%.

In addition, PureBallast 3 Ultra is prepared for challenging

water with high sediment levels. An upgraded filter design with

a faster gear motor improves the backflushing efficiency,

which significantly reduces the risk of filter clogging.

Minimized power consumption

An expanded range of UV reactor sizes ensures a close

match between PureBallast 3 Ultra and the ballast pump

capacity. For certain flows, this reduces power needs by up to

19% over previous systems.

In all configurations, automatic power management minimizes

the energy consumption. With this feature, PureBallast 3 Ultra

runs at just 50% of its potential operating power in many

situations. Yet it can ramp up to full power to maintain flow in

challenging waters. By supporting higher flow rates,

PureBallast 3 Ultra uses less energy than competing systems

in relation to the ballast water volume.

Easy installation with minimized footprint

The major components of PureBallast 3 Ultra are installed

inline, with the filter and UV reactor(s) incorporated into the

ballast water piping. System layout is simplified by the smaller

design of the upgraded filter, as well by the integration of the

Cleaning-In-Place (CIP) unit and pressure monitoring device

into the UV reactor module. These factors minimize system

footprint, reduce piping work and maximize installation

flexibility for the shipyard.

Delivered Connectivity-ready

To simplify connectivity, the PureBallast 3 Ultra scope of

supply includes a built-in field gateway. The system is

delivered ready to take advantage of Alfa Laval PureBallast

Connect, a secure digital service portal that provides remote

access to system information – anytime, anywhere. Available

on a subscription basis, PureBallast Connect offers ways to

maximize uptime, reduce workload and optimize fleet-wide.

Designed and supported for the whole vessel lifetime

PureBallast 3 Ultra is designed for enduring performance. The

filter and UV reactor(s) are made with best-in-class materials

and built to last the whole vessel lifetime. Features such as

electric actuators on the main valves, which minimize the risk
