Compliance in Water Salinities

IMO and USCG Approvals

Over 4,000 PureBallast systems have been sold, with hundreds installed as retrofits across a variety of shipyards. PureBallast has been selected for numerous vessel types, including container ships, tankers, bulk carriers, offshore supply vessels, and naval vessels. Alfa Laval’s PureBallast 3 enables full compliance with IMO and U.S. Coast Guard (USCG) regulations and is ready for revised G8 standards.

PureBallast 3 is type approved by IMO for use in fresh, brackish, and marine waters, optimising power management and other capabilities for cost-effective operation, ideal for most vessels. For ships discharging ballast in U.S. waters, PureBallast 3 systems with USCG type approval are available in two versions to meet specific operational needs. The standard USCG-certified systems provide the same capacities as the IMO-certified versions.

THE COMPLIANCE GUIDE

Dependable Performance from the Outset

Far-reaching performance

The broader the water access for your vessel, the greater its business potential.

While most ship owners focus on marine and brackish waters, three-water certification is required for areas like rivers, the Baltic Sea, and the Great Lakes. Many ports considered brackish are closer to fresh water. PureBallast 3 can treat fresh water without salt or chemical dosing, making entry no problem. It also operates efficiently in near-freezing temperatures and low-clarity waters, maintaining full flow even when UV transmittance drops as low as 42%.

Safeguarding efficiency

The less time and energy you devote to ballast water treatment, the more you have for doing business.

Efficient ballasting and deballasting are vital for vessels, yet many UV-based systems must reduce flow in low-clarity waters due to reduced UV transmittance and poor lamp cleaning. PureBallast 3, however, maintains full flow at UV transmittance as low as 42%, with automatic Cleaning-In-Place (CIP) to prevent buildup without crew effort. In IMO-regulated waters, it operates at half power, increasing only when needed for challenging conditions.
