Frequently Asked Questions
What is the main principle of the operation?
Bawat’s main method of treatment is a one-pass pasteurization technology.
Bawat BWMS is based on unique patented technology, which represents maybe the simplest solution to an ecological and regulatory issue within the international shipping industry.
Is treatment required on both ballasting and de-ballasting operations?
No, the Bawat BWMS is a one-pass treatment system.
What is the operational temperature range?
The Bawat BWMS can operate in all water temperatures.
Is there a holding time for treated ballast water?
No. The Bawat BWMS one-pass system has no limitations or requirements for after treatment holding time.
Are there any chemicals used?
The Bawat BWMS does not require addition of ‘active substances’ in any form.
Are there any restrictions for ships transporting dangerous goods?
No, there are no restrictions for the Bawat BWMS for ships transporting dangerous goods.
Are any additional measures required when operating in fresh or brackish water?
The Bawat BWMS is independent of water qualities and efficient in all turbidities, salinities and temperatures.
Is a mobile BWMS solution for deck installation available?
Yes, for deck site placement, the system can be delivered in a container size 10’, 20’ to 40’ depending on system specifications.
Is a non-skidded solution possible?
The Bawat BWMS only consists of standard marine components.
What is ballast water?
Cruise ships, large tankers, and bulk cargo carriers handle vast amounts of ballast water, typically taken from coastal waters after unloading cargo and later discharged at their next port of call, wherever more cargo is loaded. This ballast water often contains biological materials, including plants, animals, viruses, and bacteria, many of which are invasive species. Such discharges can harm aquatic ecosystems and disrupt local economies.
Definition of ballast water
Ballast water is water carried in ships' ballast tanks to improve stability.
What is the cost of a Ballast Water Management System (BWMS)?
The cost of a Ballast Water Management System (BWMS) varies according to ship type, solution wanted, service needed and so forth.
What is the minimum time required to treat all tanks?
The Bawat system is a one-pass system which means that the ballast water is treated when it has passed through the BWMS.
Are there restrictions on the water types for the commissioning test?
No, not with a Bawat ballast water treatment system!
When is the commissioning test required?
The commissioning test is required after installing a ballast water treatment system (BWTS) as of 1st June 2022.
What is BaaS (Ballast as a Service)
BaaS stands for Ballast as a Service.
Bawat BaaS offers a reception facility for yards and ports (port reception facility - prf) to ensure that vessels with inoperable or non-compliant systems can treat their ballast water effectively and discharge it safely in ports and yards.
