Ballast water filters are a preferred way of filtering ballast water due to a couple of reasons including:

  • The ballast water filter is cost-effective implying that you spend less purchasing, installing and maintaining it.
  • The use of ballast water filter is effective in removing contaminants from the water thereby making the water safe for consumption.
  • We are reducing environmental pollution. Through filtration, contamination of the environment reduces since we can filter unwanted contaminants.

Ballast water filters are a common feature in many applications as we shall see later in this guide.

Applications of Ballast Water Filter

Different applications utilize ballast water filter. Among the common ones include:

· In the shipping industry

One of the main applications of ballast water filter is in the shipping industry.

Here, the use of ballast water filter is for filtering the ballast water removing unwanted particles as well as organisms.

Ballast water treatment system in shipping industry

Ballast water treatment in shipping industry

The benefit of ballast water filtration is that the marine organisms can continue surviving in their natural habitat.

To the ship, filtration is critical in the treatment of ballast water since there is adequate removal of the unwanted particles.

The other advantage you have is you can reduce the filter element pore sizes which allows you to filter different particles from the water.

· Industrial application

Different industries utilize ballast water filters in the treatment of ballast water.

For instance, water treatment plants use ballast water filters in the filtering of ballast water before its treatment.

Manufacturing industry

Manufacturing industry

In salt manufacturing industries, ballast water filters are relevant in the filtering of the ballast water before salt extraction takes place.

Key Features of Ballast Water Filter

For a ballast water filter to function properly, there are some features that you need to consider.

Such features may include the type of material, the point of connection and the size of the ballast water filter.

Let’s have a look at these features.

· Type of material

There are three types of materials available for a ballast water filter.

They include stainless steel 304L, 316l and carbon steel.

i. Stainless steel

There are two types of stainless-steel material available for manufacturing ballast water filter, that is, SS 316 & SS 304.

The difference is in the element composition with ss 304 having 8% nickel and 18% chromium.

On the other hand, SS 316 has 16% chromium, 10% nickel and 2% molybdenum.

Each of these two has its advantages.

SS304 is a suitable material if you will use your ballast water filter in the filtration of high-temperature water.

On the other hand, SS 316 is ideal if you are constructing corrosion free ballast water free.

The molybdenum present is responsible for the filter not being corrosive.

ii. Carbon steel

Carbon steel material is one that has a high carbon content.

The advantage you have with this material is it is cheaper than the other materials.

You also have the option of hardening the carbon steel through heat treatment meaning that your ballast water filter can withstand pressure.

However, there are a couple of factors that hinder the use of this material in the manufacture of ballast water filter.

This includes weldability in cases where the carbon content is higher than that of steel.

Weldability has an impact on the joints meaning that quite often, you will have to replace them.

Carbon steel comes in three different variants, that is low or mild carbon steel, high tensile steel, and higher carbon steel.

These variants have different carbon contents with higher carbon steel containing a higher content of carbon.

A high carbon content implies that heat treatment of the material has taken place.

iii. UNS S32760 Filter Housing for Seawater

This kind of material is ideal for filtering salty water such as sea water.

This is due to the chemical composition that makes it corrosion free.

It is chemical composition includes Tungsten, chromium, nickel, copper, and molybdenum.

Another benefit you have with this material is its strength which can endure a considerable amount of pressure.

· Size of the ballast water filter

The size of the ballast water filter will differ depending on the application that you are going to use.

A large application will need a large ballast water filter to filter the ballast water effectively.

Section of ballast water filter

Section of ballast water filter

Likewise, if you have a moderate application, you will need a small ballast water filter that will effectively filter your ballast water.

· Point of connection

There are different points of connection to a different ballast water filter.

Each one is supposed to fit in a particular position on your application.

It is imperative that as a feature, the point of connection needs to be compatible with your application for proper functioning.

Types of Ballast Water Treatment Systems

There are different ballast water treatment systems available for selection depending on several factors which include:

  • Environment friendliness of the treatment system
  • Crew safety
  • Cost-effectiveness
  • Availability of space on the ship.
  • How easy it is to install and operate
  • The effectiveness of the system is on ballast water organisms.

So, which are these types of ballast water treatment systems?

They include:

Ballast water treatment system

Ballast water treatment

· Electric pulse system

Electric pulse system utilizes short energy bursts to kill organisms which are present in the ballast water.

Electric pulse system features two metal electrodes which generate an electric pulse for treating ballast water.

There are two forms of electric pulse systems available for treatment of ballast water.

That is electric field technology and electric plasma technology.

In electric field technology, there is a generation of high energy pulse that results in the formation of the plasma arc.

It is this plasma arc that is responsible for killing the organisms present in the ballast water.

In electric plasma technology, there is a supply of high energy pulse to a mechanism available in the ballast water.

This generates a plasma arc which is responsible for killing the organisms in the ballast water.

It is important to note however that this type of technology is still developing.

· Heat treatment system

The use of heat treatment in the ballast water treatment system involves heating the ballast water till it reaches the boiling point.

Boiling point kills all the organisms present in the ballast water thereby making it safe for consumption.

Heating of the ballast water can utilize a separate heat system or utilize the engine’s heat.

Heat treatment system renders the organisms inactive by killing them.

The limitation of using this type of treatment is that it takes time for the organisms to be inactive.

Also, continuous use of the system causes corrosion of the tanks.

In the long run, you will have to purchase another tank to avoid leakage of the ballast water.

· Ultraviolet treatment

This method consists of UV lamps surrounding a chamber that allows the ballast water to flow through.

The lamps (Amalgam lamps) creates ultraviolet rays that act on the organism’s DNA rendering them harmless.

Once they are harmless, they are not in a position to reproduce.

The method is effective in destroying a wide range organism thus making it useful in ballast water treatment.

· Chemical disinfection

Chemical disinfectant refers to the treatment of ballast water using biocides disinfectant.

The biocides disinfectant removes unwanted particles and other invasive organisms.

There are two types of biocide disinfectant available for use in the treatment of ballast water.

That is, oxidizing and non- oxidizing.

Oxidizing biocides refers to disinfectant whose purpose is to inactivate organisms present in the ballast water.

Such types of disinfectants include bromine, chlorine, oxidizing agents and iodine.

Oxidizing biocide destroys the organism by destroying its structure including the cell membrane.

Non- oxidizing biocide destroys the organisms by interfering with its reproductive structure.

Such biocides include menadione and vitamin K.

However, the use of chemical treatment in some instances may prove to be inappropriate due to the effect it has on the environment.

You need to take care when using this method in treating ballast water so that it does not have an adverse impact on the marine ecosystem.

· Cavitation treatment

Cavitation treatment system refers to the treatment of ballast water using ultrasonic energy.

What happens is that this energy produces ultrasound of high energy which is responsible for the treatment of the ballast water.

Treatment of the ballast water system, in this case, occurs by killing the organism’s cells.

However, you will have to combine this technology with other treatment systems when treating ballast water.

· Magnetic field treatment

Magnetic field treatment utilizes coagulation technology in the treatment of ballast water.

In this ballast water treatment system, the coagulants mixed with magnetic powder and poured into the ballast water.

This results in magnetic floc formation constituting of the marine organisms due to attachment of various species to the mixture.

Once this happens, the system uses magnetic discs to remove the magnetic floc from the water.

· Filtration system

The filtration system is the typical type of ballast water treatment available for use.

This is due to its efficiency and relatively low cost.

Also, the use of this system does not hurt the marine ecosystem.

This implies that the system will not hurt the microorganisms.

Filtration system uses filter discs, a powerful hydro cyclone, coagulation or screens to filter unwanted particles from ballast water.

The use of screens or discs in the filtration of ballast water is to remove unwanted particles from the water. Automatic backwashing helps in achieving this.

Adjusting the screen pores allows you to filter different sizes of unwanted particles from the ballast water.

However, you need to note that the use of screen alone is not effective in ballast water treatment.

Ballast water filter element

Ballast water filter element

As such, you need to use it together with other ballast water treatment systems.

On the other hand, a hydro clone is an efficient option of filtration.

The hydro clone equipment uses high centrifugal force which rotates the water thereby separating solids from it.

The ease of installing this equipment and operating it makes it ideal for filtration of ballast water.

Coagulation aids in the filtration of tiny particles from the ballast water.

In this process, small particles stick together which increases their size.

Once the coagulation reaches a particular size, filtration takes place.

The coagulation of the particles is called flocculation.

The limitation of using coagulation for filtration is that you will need an additional tank to treat the ballast water.

You will, therefore, need enough space to accommodate the tank.

The other option is the use of media filters.

In this case, compressible media filters are ideal at filtering lower density particles which are small in size.

How do Ballast Water Filter Works

Understanding how a ballast water filter works is right in ensuring the efficiency of the filter.

Let me illustrate to you how it works.

Ballast water filter system - Gloen Patrol

Ballast water filter system – Gloen Patrol

Most ballast water filters usually are at the inlet of a ballast water treatment system.

As water flows into the system, it has to pass through the ballast water filter.

As it passes through the filter, it flows through the filter element.

It is the filter element that is responsible for filtering the ballast water.

As filtration takes place, clogging takes place on the filter element.

At this point, the filter element cleans itself through backwashing.

It is important to note that for effective filtration of your ballast water, you need to consider several factors such as the pressure drop and the flow of the ballast water.

The advantage you have with ballast water filter is you can control the size of the filter element.

This helps you when it comes to determining the degree of filtration of the ballast water.

Control the size of the filter element is crucial when you want to maintain the marine ecosystem.

You can return marine organisms captured during the filtration process back to their natural habitat.

As such, ballast water filters are a useful and eco-friendly way of filtering ballast water since it conserves the marine ecosystem.

Requirements for Ballast Water Filtration and Separation

There are several requirements that ballast water filtration and separation have to meet for it to be effective.

Among these requirements includes:

· The precise degree of filtration

For the ballast water filter to work effectively, it needs to filter all the unwanted particles and organisms from the ballast water.

This entails making sure that the pore size of the filter element is correct.

· Installation

The ballast water filter needs to be an easy to install gadget.

This will ensure that you can install and remove during maintenance.

Given the area of application, the installation needs to consume less time.

· Cost

Having a low-cost ballast water filter is essential in reducing the overall cost of ballast water treatment.

You need to ensure in as much as the cost is low, it does not compromise the quality of operation.

· Filter material

Ensure that the filter material you select does not react with its environment.

For instance, in seawater, ensure that the filter does not react with the water.

· Clogging

Another requirement for a ballast water filter is that you need to ensure it can clean itself during clogging.

The advantage of this is it allows maximum operation during ballast water treatment.

· Compatibility

Lastly, ensure that the ballast water filter is compatible with other types of ballast water treatment systems.

Compatibility is necessary to provide maximum treatment of ballast water.
