The ballast water management standards will be phased in over a period of time. As an intermediate solution, ships should exchange ballast water mid-ocean. However, eventually most ships will need to install an on-board ballast water treatment system. [4] A number of guidelines have been developed to help implement the convention.
The International Convention for the Control and Management of Ships' Ballast Water and Sediments (Ballast Water Management Convention or BWM Convention) is a 2004 international maritime treaty which requires signatory flag states to ensure that ships flagged by them comply with standards and procedures for the management and control of ships' ballast water and sediments.

Diagram showing the water pollution of the seas from untreated ballast water discharges Ballast water discharges by ships can have a negative impact on the marine environment . The discharge of ballast water and sediments by ships is governed globally under the Ballast Water Management Convention , since its entry into force in September 2017.
Hyde GUARDIAN ® Ballast Water Treatment System Earns Alternate Management System Approval from United States Coast Guard PITTSBURGH--(BUSINESS WIRE)-- Calgon Carbon Corporation (NYS: CCC ...
Ballast water discharges are believed to be the leading source of invasive species in U.S. marine waters, thus posing public health and environmental risks, as well as significant economic cost to industries such as water and power utilities, commercial and recreational fisheries, agriculture, and tourism.

Also established by this ruling was the approval process of Ballast Water Management Systems. Independent laboratories vetted by USCG test the equipment, incorporating EPA Environmental Technology Verification Program land-based protocols. For foreign-type approved systems installed before the compliance dates, a 5-year grandfather period was ...
Ballast, other than cargo, may be placed in a vehicle, often a ship or the gondola of a balloon or airship, to provide stability. A compartment within a boat, ship, submarine, or other floating structure that holds water is called a ballast tank. Water should be moved in and out from the ballast tank to balance the ship.
The carriages maintain approximately balance, so propelling the wagon requires only applying the force to unbalance the system. This is done by artificially increasing the mass of the car standing in the mountain station with water, so that the gravity acting on this additional mass can move the train. Both cars therefore have a ballast water ...
