As part of US Coast Guard (USCG) protocols, BWMS are designed to safely protect the environment and economies from invasive aquatic species damage.
Testing for Evoqua’s SeaCURE system for BWMS was completed at the Marine Environmental Resource Center in Baltimore, Maryland under conditions that replicate the environment in which the system will be operating. Evoqua is the first to complete this phase of testing with a US Independent Laboratory. The low salinity (brackish) trials are the first of three phases required for full USCG approval. The SeaCURE system will now move on to fresh water testing and sea trials planned for later in the year.
The SeaCURE system has already attained alternate management systems (AMS) acceptance for fresh, brackish and full saline water and was the first electrochlorination system to receive AMS acceptance for all three salinities. AMS approval is a temporary designation granted to a system that has already been approved by an international administration. Evoqua says it believes its SeaCURE system is the only side-stream electrochlorination system on the market to be AMS approved for all three types of water. The USCG protocol BWMS testing for the brackish water phase was completed on July 30.
The company sites a 2005 paper by Pimentel et al. on invasive species hat estimates the economic impact to the US alone is more than $120 billion in damages every year.
Designed for gas carriers, tankers, bulk carriers and container vessels, SeaCURE systems for BWMS are suitable for vessels with higher ballast water flow rates ranging from 500 to 4,000 cubic meters per hour. Higher flow rates can be accommodated by using multiple units. SeaCURE systems for BWMS are equally suitable for retrofitting on existing vessels as well as for installation and use on new-build ships.
SeaCURE systems for BWMS are based on the technology used in Evoqua’s Chloropac system, which has been used for more than 40 years in the maritime industry. The SeaCURE system is similarly designed to save energy and reduce operating costs for the ship owner. Variations in demand are taken into account to deliver biocide only at the dosage necessary for successful ballast water treatment.
