TECHCROSS

Introduction

Since its establishment in May 2000, Techcross has been growing into a leading company in electrolytic water management through continuous research and development. The Electro Cleen System (ECS) by Techcross integrates the environmental paradigm with the shipping industry by obtaining the world’s first in-principal Basic Approval from the International Maritime Organization (IMO) in 2006. Final and Type Approvals were obtained in 2008. Techcross has established various records including: delivering the industry’s first explosion-proof type ballast water management system and the world’s first installation on a VLCC (very large crude carrier); emerging as a leader in the marine environmental industry.

Product Description 

Electro Cleen System

• Treats all incoming water and sediment passing through the electrolysis chamber unit with ‘Techcross’ innovative technology
• Eco-friendly with low power consumption requirements because a fine mesh filter is not required
• ECS differs from typical electro-chlorination systems. The electro-chlorination treatment process of many other systems involves the electrochemical generation of biocide solution on board from the treatment of a small fraction of incoming water and then the injection of the highly concentrated hypochlorite solution directly into the ballast pipeline. However, in the case of ECS, all the ballast water is treated directly as it passes through the Electro Chamber Unit then this fully treated water flows into the ballast tanks.
• After treatment, the treated sea water containing residual hypochlorous acid flows into the ballast water tanks. The residual hypochlorous acid in the water maintains disinfection efficacy in the ballast tank and prohibits re-growth of microorganisms. Any remaining TRO will undergo a natural degradation process or will need to go through a neutralization process before being discharged. This neutralization process minimizes any negative impact to the marine environment.
• ECS (Electro Cleen™ System) is a Ballast Water Management System (BWMS) using the principle of electrolysis to effectively disinfect ballast water. With the application of electric currents to the titanium electrodes, the electric potential produced increases disinfection efficacy by destroying cell membranes of microorganisms as a result of generating voltage. In addition, OH- radicals generated during the electrolysis procedure by the electrodes also disinfect microorganisms. Through electrolysis, sufficient amount of TRO is generated, preventing the re-growth of micro-organisms and maintaining disinfection efficacy.

Supporting Equipment

• Power Distribution Equipment (PDE): Supplies and monitors power to all the components of ECS. The proper model is selected based upon the capacity of the ballast tank on a ship.
• Auto Neutralization Unit (ANU): Responsible for neutralizing residual TRO levels during discharge of treated ballast water. The hypochlorous acid degrades over a period of 8-10 days. If the hypochlorous acid is not degraded to concentrations to not affect the environment, then the ANY will neutralize the ballast water with Sodium Thiosulfate during de-ballastingas monitored by the TSU.
• TRO Sensor Unit (TSU): Monitors the concentration levels of TRO during ballasting and de-ballasting. Hypochlorous acid is produced at a level of 10ppm for maximum disinfection efficacy. The TSU constantly monitors this naturally degrading level so that if neutralization is needed before discharge, the CPC will send a signal to the ANU to begin the neutralization process.

Control System

• CPC (Control PC &SW): The CPC is composed of Windows-based software focusing on user convenience and ease of use. The control system allows the operation of ECS through both manual and automatic modes. The CPC is operated using a touch screen for simple operation.

Sensors

• FMU (Flow Meter Unit): Measures the flow of water to facilitate the operation of ECS according to measurement results .
• CSU (Conductivity Sensor Unit): Measures the conductivity of seawater to transfer measurement results to CPC.
• FTS (Freshwater Temperature Sensor): Measures the temperature of freshwater that is used to cool the heat produced by the rectifiers

Other

• T-Strainer: 3mm mesh T-strainer aids in protecting the high quality electrodes in the ECU
