What Is a Biocide Chemical for a Cooling Tower?

What Is a Biocide Chemical for a Cooling Tower?

Cooling towers are used industrially to release heat generated during a mechanical process. Often the water used in cooling comes from a natural source and is not highly filtered. This means it can contain natural sediments, minerals, and biological content.  

All these additional materials can lead to a build-up of organic material on the membranes of the cooling tower. Controlling the bacteria and other microorganisms is often done using biocide chemicals, and is essential if you wish to keep your cooling tower operating efficiently. 

Types of Biocides Used in Cooling Towers  

By far, the most common type of biocide chemicals used is chlorine and chlorine derivatives. This is most common because of its relative cheapness, and effectiveness at oxidizing many types of bacteria.  

Oxidizing biocides, such as chlorine, work by reacting with organic molecules in the microorganisms and causing them to become unstable, thus killing the organisms. In addition to gaseous chlorine, the following are used commonly as oxidizing biocides: 

  • Chlorine dioxide 
  • Chloramines 
  • Potassium Ferrate 
  • Ozone 
  • Hydrogen Peroxide 
  • Iodine 

While all of these chemicals are effective at oxidizing organic materials, it is important to understand the material of the cooling tower you are treating. For example, certain membrane materials may be sensitive to chlorine. Additionally, iodine and hydrogen peroxide can have similar negative effects on certain polymers which may be present. 

You may also find that a blend of chemicals works best at controlling the organisms present in a certain system. Many biocide chemical blends are currently available for purchase in bulk.  

Why Do You Need Biocide Chemicals? 

Biocides are important for controlling the growth of organisms in cooling towers. Often referred to as “biofouling,” when bacteria, fungi, or other creatures accumulate on the membranes of an industrial system, they can have a distinct influence on the efficiency of heat transfer. This is because the layer of soft organic material acts as an insulator between the membranes and the cooler water, sort of like a rubber handle on a frying pan.  

While there are other approaches to handling biofouling, such as physically cleaning the membranes, often biocides are more effective. This is in part because the organisms that are causing a problem will multiply exponentially, so it is necessary to remove all of them to prevent regrowth.

What Is Fouling? 

What Is Fouling?

Fouling refers to the buildup of solid matter in a water system, like scum on the surface of a pond, or rust on the hull of a boat. This buildup can take on many forms, both living and non-living, and in industrial settings, it can be a real headache to alleviate.  

Read on to see more examples of fouling, and to learn about the negative effects it can have on an industrial system. 

Types of Fouling: Biological   

Material buildup can be distinguished simply as biological (aka “biofouling”) or non-biological.  

Biofouling can refer to the build-up of… 

  • Bacteria 
  • Algae 
  • Fungus 
  • Mussels 
  • Barnacles 
  • Other microorganisms 

Typically, biofouling is more common in warmer water and slower-moving water. Biofouling is a particular issue in ocean-based systems, because of the microscopic biodiversity of seawater. 

Types of Fouling: Non-Biological 

Non-biological fouling can occur simultaneously with biofouling, but is dependent on the make-up of the water, and material the system is made of. Here are a few examples: 


This refers to the building up of particles, maybe through pollution or natural particles like silt or leaves. 


Precipitation occurs when chemicals in the water lose their solubility (through temperature change or change in the water movement), and collect in solid form. 


Just like rust, certain materials will react with the water and may start to release solid material which can collect and affect the efficiency of the system. 


Sometimes if the water is cold enough, it will freeze in slower-moving areas. More commonly, oils or waxes will freeze in membranes and slow the flow of water. 

Chemical Reaction 

If a new chemical is introduced to the system, maybe as a biocide or cleaning agent, it may react with existing chemicals and form solids, similar to precipitation. 

Why Is Fouling Bad? 

Fouling can cause real problems for the efficiency of industrial water systems. Sometimes it can clog pumps and smaller pipes that are important for the flow of water. This can slow the efficiency of water movement but also lead to the dangerous building up of pressure in delicate areas. 

If the system is being used for heat exchange (water is often used as a large-scale coolant), then buildup on the membranes meant to release heat into the water will hurt the transfer of heat.  

Certain types of buildup can also contain dangerous chemicals and bacteria that make the water hazardous to human consumption. It is important to understand the type of buildup affecting your system and try to mitigate it.

What Are Cured Epoxy Resin Removers?  

What Are Cured Epoxy Resin Removers?

Epoxy resins are extremely versatile epoxide polymers used in several industries. But while these resins are frequently applied for various reasons, they also need to be removed for various reasons. In this blog post, we’ll take a closer look at epoxy resins and what chemicals it takes to remove this durable substance. 

Epoxy Resins Explained 

Epoxy resins are reliable due to their durability and strong adhesive qualities. They are generally blended with a hardener or curing agent to cure the epoxy, solidifying it into a stronger substance. Here are only some of the industries this substance is found: 

  • Vehicle manufacturing 
  • Boat manufacturing 
  • Aircraft manufacturing 
  • Bicycle manufacturing  
  • Paints and coatings 
  • Adhesive for various materials such as wood, glass, or metals 

Unfortunately, epoxy can wear down or need to be replaced, but once the epoxy resin is cured, it can be very difficult to remove. Physical removal of cured epoxy is tedious and can even damage the surface bonded to the resin. There is however another option: chemical removal.   

What Does Chemical Removal Mean?   

Chemical removal of epoxy resin involves using a specialized aggressive chemical solution, or cured epoxy resin removers, to penetrate the resin and break it down, weakening its adhesion to the surface. One of the most common chemicals used for cured resin removal is methylene chloride, which is an effective yet controversial solvent due to its toxicity and negative environmental effects.  

Methylene chloride poses multiple risks to both human health and the environment:  

  • Highly flammable 
  • Can cause severe eye irritation and damage 
  • Can cause skin irritation 
  • Potentially carcinogenic 
  • Can cause coughing, wheezing, dizziness, or respiratory irritation if inhaled 
  • Contributes to ozone depletion as an air pollutant 

Are there any Safer Options for Cured Epoxy Resin Removers?   

Fortunately, there are specially formulated products that effectively replace hazardous solvents like methylene chloride and ensure both safety and quality. One example of the ideal epoxy resin remover is Safe Strip, an environmentally preferred resin and paint solvent that possesses many benefits:   

  • Biodegradable 
  • Nonflammable 
  • Recyclable 
  • Low VOC emissions 
  • Removes coatings in only one step 
  • Effective on cured and uncured coatings 
  • Effective on all coatings, even two-step high solids polyurethane and epoxy resins 
  • Recyclable  
  • Lower Inhalation Hazard Index than methylene chloride, making it significantly safer for industrial and commercial use.

What Is an Epoxy Resin Remover?

What Is an Epoxy Resin Remover?

Epoxy resins are generally used in various industries for their strong adhesive properties, chemical resistance, heat resistance, and versatility. These types of resins are used for dozens of applications, including: 

  • Vehicle manufacturing 
  • Aircraft manufacturing 
  • Paints and coatings 
  • Bicycle manufacturing  
  • Boat manufacturing 
  • Wood, metal, or glass adhesive 

These polymers are usually mixed with a curing agent or hardener in order to harden and “cure” into a stronger substance.  

Though these polymers are extremely durable and strong, they can sometimes wear down and need to be removed. It can be very tricky to remove cured epoxy resin, as physical removal can be tedious and damaging to the surface bonded to the resin. Luckily, specific chemicals can be used to make the epoxy removal process much easier.  

What Chemicals Can Be Used as Epoxy Resin Remover? 

A good epoxy resin remover will be an aggressive solvent that effectively breaks down the epoxy and successfully removes it. Unfortunately, most of these aggressive solvents contain highly toxic compounds that pose various health risks to industrial workers and can be damaging to the environment as air pollutants. For example, methylene chloride has been used for epoxy removal, but is carcinogenic and contributes to ozone depletion.  

A safer chemical for epoxy removal can be acetone, which is a strong cleaning agent that effectively removes various epoxy resins. Those searching for a highly effective and specifically formulated product may be more interested in Safe Strip, an environmentally preferred epoxy resin and paint remover which offers numerous benefits over hazardous chemicals:

What Is the Most Commonly Used Paint Remover Chemical?

What Is the Most Commonly Used Paint Remover Chemical?

The most utilized paint remover chemical is methylene chloride, also known as dichloromethane. Though effective and relied on by many industries, this chemical is controversial due to its toxicity.  

In this blog post, we’ll take a look at the dangers associated with dichloromethane exposure and alternative chemicals for paint removers that aren’t only safer, but greener. 

Dangers of Dichloromethane 

Some of the main concerns of using paint removers that contain dichloromethane are worker safety and environmental health. Dichloromethane is classified as an air pollutant and has several hazards associated with exposure to this chemical: 

  • Flammable 
  • Contributes to ozone depletion 
  • Potentially carcinogenic, as high concentrations can cause liver and lung cancer 
  • Can cause severe eye irritation and damage 
  • Can cause skin irritation 
  • If inhaled, it can cause coughing, wheezing, and respiratory irritation 
  • High levels of exposure can cause nausea, dizziness, or even unconsciousness 

Methylene chloride has even been banned in U.S. consumer paint removers and in the EU. It’s no surprise that many companies are beginning to make the switch from traditional hazardous paint remover chemicals to modern products that are much safer, not only for workers but for the environment as well.  

One example of such a product is Safe Strip, an environmentally conscious paint and resin solvent that has been formulated to replace hazardous solvents like methylene chloride, benzene, and toluene.
