Discover KBAL. Ballast Water Treatment System

Ballast as per normal

KBAL systems designed purely for marine use, utilizing a 2-step process of Pressure Drop and UV disinfection. Technology is highly effective, enabling vessels to operate in all kinds of water, independent from temperature, salinity, and turbidity and without operational restrictions.

Seamless integration into existing ballast systems. KBAL also offers a unique solution for AFT peak treatment since does not require an additional system. Ideal for vessels having submerged pumps.

A sampling pipe is always to be provided both on the BWMS intake, and discharge.

The major components of the KBAL system are
the pressure vacuum reactor and the UV lamps.

The Pressure Vaccum Reactor

Innovation on your ship

The pressure vacuum reactor working in combination with a vertical ballast water drop line, ensures a low temperature boiling condition that eliminates the majority of the organisms. Any remaining bacteria are effectively eliminated by the UV Chamber mounted downstream on the pressure vacuum reactor.

The KBAL system requires a minimum pressure of 2.0 bar on the inlet of the reactor. This pressure is ensured typically from the vessel’s ballast pump although, in specific cases, a booster pump will be required. Type and size of this pump will vary, depending on the specific ships application.
The same applies for the so called ballast water lifting pump, B.L.P: For some ship’s applications, there may be a need to install such a pump to ensure sufficient lifting capacity during topping up the ballast tanks.

Working Principles

!

Pressure Vaccum Reactor

Working Principles

The pressure drop in combination with a vertical ballast water drop line, ensures a low temperature boiling condition (at ambient temperature) that eliminates the majority of the organisms.

Even very small particles of mud are still biologically treated in KBAL system, which is impossible for other technologies.

Any remaining bacteria are effectively eliminated by the UV chamber, mounted downstream on the pressure vacuum reactor.

Operation Pattern

The system operates both during ballasting and during discharge, preventing any regrowth of microorganisms that may have occurred and ensuring safe compliance with the D-2 standard and the discharge standard (USCG) under most demanding operational scenarios

Monitoring

The KBAL system is controlled and monitored by a specially designed control system named, e-SEA ®KBAL monitoring system. The monitoring system includes remote control of valves and the UV, set points for flow and pressure regulators, and logging of various data.

KBAL models range

A BWTS is obligatory

The ratified IMO BWM Convention mandates ships from September 2017 and onwards to treat ballast water and ensure compliance with the D-2 standard (IMO) and the discharge standard (USCG).

Ship owners should select and install a ballast water system in any new build delivered while, retrofit one at next renewal survey to existing vessels.

However which is the best system to choose, what are the main criteria to consider?

8 main factors to consider before choosing a BTWS

1. Treatment methods

There are two generic types of process technologies used in ballast water treatment such as solid-liquid separation and disinfection which in turn, divided into physical and chemical methods.
UV-radiation, cavitation, pressure vacuum, heat, chlorination, electro chlorination and ozonation are some of them. Knutsen’s KBAL systems utilize a physical disinfection process which is based on pressure/vacuum, being highly effective, risk-free and low cost process. KBAL using no filters nor chemicals, just pressure vacuum and UV, is an effective system and the best alternative to choose for your fleet.

2. To be IMO and USCG type approved

A Type Approval demonstrates that a prouct conforms to recognized industry quality standards, international conventions, demanding verifications of production controls, reviews, tests and more. So, a system approved by IMO and USCG not only is a credible system but it is a system evaluated in detail by top experts. This means that it is a system you can trust for your vessels. KBAL ballast water treatments system is approved by IMO while it is in process to get the USCG type approved within the next months. Moreover the system has already obtained the ABS Type Approval, Lloyds Register Type Approval, DNV-GL Type Approval and, has USCG AMS Certification.

3. Operational Costs
