“…It can be clearly seen from the table 2 that, rate of disinfection is increased by almost 2 times compared to that of only chlorination when it is combined with hydrodynamic cavitation. Less amount of sodium hypochlorite requirement will also result into less formation of disinfection by products which are harmful to the environment and which need to be disposed of safely [35,36] after the disinfection treatment. The per pass disinfection is also an important parameter as it tells us the number of passes through the cavitating device needed to achieve log 4 reduction.…”

“…Different alternatives to achieve these limits exist, including use of strong oxidants such as chlorine (e.g. Werschkun et al 2012;Zhang et al 2013). Chlorine may be applied to ballast water either directly or indirectly via in situ electrochlorination of sea water.…”

The International Maritime Organization (IMO) will enforce a new abundance-based performance standard for ballast water in September, 2017. Strong oxidants, like chlorine, have been proposed as a method for achieving this standard. However chlorine treatment of ballast water can produce hazardous trihalomethanes. We assessed maximum trihalomethane production from one chlorine dose for three types of ballast water (fresh, brackish and marine) and three levels of total organic carbon (TOC) concentration (natural, filtered, enhanced). While the current standard test considers a five day voyage, there is a high possibility of shorter trips and sudden change of plans that will release treated waters in the environment. Water source and TOC significantly affected trihalomethane production, with the highest amounts generated in brackish waters and enhanced TOC concentration. The concentration of brominated trihalomethanes increased from background levels and was highest in brackish water, followed by marine and fresh water.

“…According to Kim (2013) in the future BWE is no longer permitted due to the uncertainty related to ships stability and the effectiveness of the method, so D2-Standard will be the only option for shipping companies to fulfill by installing BWMS. However, thing to be concerned if D2-Standard becomes the only option is a by-product of chemicals that can have a negative effect on aquatic organisms (Zhang et al, 2013), as well as byproducts of disinfectants (halogenated) such as dibromochloromethane, four haloacetic acids, and sodium bromate. The use of the active substance as a disinfectant to kill the NIS in the ballast water will have a bad effect on the original organism in which the ballast water is removed, even though the active substance has been neutralized by a reducing agent such as sodium thiosulfate (Pelorus and Karahalios, 2017).…”

This study aims to analyze the level of compliance of the ship’s crew toward The BWM Convention. (Ballast Water Management Convetion). This research is kind of qualitative using a research design that relates the independent variables and the dependent variable at the same time. The study was conducted in the Offshore Port of Taboneo with a total sample of 54 respondents. The research data is primary data from interview by using questioner and secondary data obtained from interview and literature study. The results showed that the Compliance of the crew on the ship that has been equipped with Ballast Water Treatment System (BWTS) is 66.67 % of respondents fall into the category approach to obedient and 33.33 % of respondents approach to non-obedient category. So also the compliance of crew on board ship that has not been equipped with BWTS there are as many as 60.61 % of respondents fall into the category approach to obedient and 39.39 % of respondents approach to non-obedient category.
