SunRui presented more than twenty-five National Standard, Military Standard and Industry Standard or Corrosion Control technology, the industry standard of sodium hypochlorite generator technology for electrolysing seawater, the first industry standard for design and installation of ballast water treatment system for vessels with electrolytic method applied to BWMS technology . SunRui BalClor® ballast water management system is a major auxiliary equipment on vessels with fully independent ownership, Sunrui was the first IMO manufacturer to give final approval in China and with DNV, CCS, LR, NK, BV, ABS type approval certified and AMS approval certificate from USCG.

SunRui BalClor® Ballast water management system occupies the top three in the world, especially the first order of installation quantity on large vessels. SunRui is also the only qualified manufacturer of the Electrolytic Sodium Hypochlorite system applied to the Nuclear Power Station in China, shares 90% of the market in Nuclear Power Station, 70% market in Thermal Power Station. Corrosion Control products share 30% of the market in China.

How does this system work?

The BalClorTMS system is based on the so-called "Sidestream Electrolysis" principle. When taking the ballast water, it is first filtered with a backwashing filter. This filter removes all organisms with a size larger than 50 μm. Subsequently, by means of the Electrolysis Unit, a small part of the ballast water is converted into a solution with, inter alia, a high sodium hypochlorite concentration. The solution generated by the electrolysis unit is then injected into the ballast water main flow in order to effectively disinfect the ballast water. This solution kills all micro-organisms in the ballast water in order to meet the D-2 standard. Neutralization: After the filtration and disinfection of the ballast water, the ballast water can be discharged into the surface water without any problems.
