There are three steps in the BWMS treatment process of ballast water. The first is filtration, followed by "electrolysis of seawater to produce sodium hypochlorite for sterilization" and finally "neutralization."
The first step is to create a plan.
Use an automatic backwash filter with a filtration accuracy of 50um when filling water to ensure that all ballast water is properly filtered before use. This step is capable of filtering out the majority of marine organisms as well as solid particles larger than 50 microns in size.
Step 2: Make a list of all of the things you want to do.
In order to sterilize water, electrolysis of seawater is used to produce sodium hypochlorite.
Take a small flow of seawater from the ballast water mainline and pass it through the electrolysis device, where it will be electrolyzed to produce a sodium hypochlorite solution with a high concentration of sodium. It is then injected back into the ballast water main pipe Road, where it is mixed with the ballast water in the main pipe and diluted to a specific concentration before being discharged into the sea. It is possible to achieve the desired sterilization effect with this concentration of sodium hypochlorite after filtration while also effectively killing the remaining plankton, pathogens, larvae, and spores after filtration (D-2 and other standards). The concentration of active substances in the ballast water pipeline is determined by the TRO (TRO Automatic Control of Analyzer and Control System), which is an automated control system.
Step 3: Make a list of all of the things you want to do.
"Neutralization"-When the concentration of residual chlorine in the ballast water is less than the IMO specified value during ballast water discharge, the neutralization system will not start, and the ballast water will be directly discharged to the destination sea area; when the concentration of residual chlorine in the ballast water is greater than the IMO specified value during ballast water discharge, the neutralization system will start, and the ballast water will be directly discharged to the destination sea area. When the specified value is reached, the neutralization system is automatically activated, and neutralizer is injected into the drainage pipe in order to neutralize any residual oxidant present. It is automatically controlled by the control system in response to information returned by the TRO detector about the concentration of neutralizer to be used in the process.
An actuator and a butterfly valve are both included in the 4 inch Pneumatic Actuator Wafer Butterfly Valve Supplier. The 4 inch Pneumatic Actuator Wafer Butterfly Valve Supplier is opened and closed by a circular disc that rotates with the valve stem in order to realize the action of the pneumatic actuator wafer butterfly valve supplier. This valve is primarily used as a shut-off valve, but it can also be designed to perform additional functions such as adjusting, stepping valve, and adjusting. There is a low pressure in the 4 inch Pneumatic Actuator Wafer Butterfly Valve Supplier at the moment. Large and medium-diameter pipes are becoming increasingly popular. It is a rotary regulator, as the name implies. This device has the advantages of having a small volume, being lightweight, and having a high rated flow coefficient.
It is particularly well suited for large diameter, high flow applications such as concentrated muddy slurry or boiler kiln flue gas control, among others.
