chemical treatment of wastewater

Process of Chemical Treatment of Wastewater

Wastewater chemical treatment is a necessary process that is done to remove contaminants and solids from the water, in order to ensure purification so that it is deemed safe for humans and the environment.

water treatment chemicals

Though there are different types of treatments for wastewater, chemical treatment is usually an additional process involving addition of specific chemicals for various purposes, including: 

  • Neutralization 
  • Precipitation (Coagulation and Flocculation) 
  • Oxidation 
  • Ion exchange 
  • Disinfection 

Neutralization: 

This step involves the addition of either an acid (for lowering pH) or an alkali (for raising pH), depending on the pH of the wastewater. Sodium hydroxide and sulfuric acid are chemicals that are commonly utilized for this step.  

Precipitation (Coagulation and Flocculation): 

This part of the treatment is extremely important and involves adding coagulants and flocculants to create a floc, or large clusters of solid particles, that can later be removed from the water by filtration. Coagulation is the process of destabilizing negatively charged particles by introducing positively charged chemicals, which will allow for the solid particles to form into large groups. After this step, flocculation is performed in order to further ensure the growth and accumulation of the floc. Commonly used coagulants are iron (III) sulfate and aluminum sulfate, which can also simultaneously act as a flocculant.  

Oxidation: 

This step involves the addition of an oxidizing agent to reduce the chemical oxygen demand levels of the water and remove organic and oxidizable inorganic particles. Hydrogen peroxide and ozone are commonly used oxidizing agents.  

Ion Exchange:  

This important step is done to soften hard water, which can result in scale formation or residue. Positively charged sodium ions, usually from sodium chloride, are added to the water to exchange spots with calcium and magnesium, which are the ions responsible for water hardening.  

Disinfection: 

This step is meant to purify the water by killing any bacteria or pathogens. Chlorine is commonly added to kill bacteria and viruses, ensuring complete disinfection of the water.

Practicing Green Chemistry – Eco Friendly Cleaning Solutions

The push for companies to use eco-friendly products has reached manufacturers of industrial cleaning solutions and the businesses that use them, as it has been revealed that many industrial cleaning and degreasing solvents are harmful to both people and to the environment. Carbon footprint-conscious companies, such as Ecolink, are aiding industrial companies practice the art of green chemistry, which involves transitioning to eco-friendly cleaning solutions.  

Eco-Friendly Cleaning Solutions in Green Chemistry 

Why is using eco-friendly chemicals part of green chemistry? As it turns out, several of the 12 principles of green chemistry are related to the specific types of chemicals that are utilized to perform chemical reactions. A few of these principles are:  

  • Designing Safer Chemicals 

Designing safer chemicals emphasizes the use of chemical solutions that are as nontoxic as possible while still being efficacious. Nontoxic or low-toxicity chemicals generally do not pose a large threat to wildlife, and thus are eco-friendly.   

  • Safer Solvents and Auxiliaries 

According to this principle, the use of auxiliary chemicals such as solvents should be avoided. However, when they must be used, they should be as safe as possible. This is an important principle because solvents account for 50-80% of the mass of a standard batch chemical process; thus, their potential impact on the environment is significant. Therefore, when a large amount of solvent must be utilized, choosing environmentally friendly options will certainly benefit the planet.  

  • Use of Renewable Feedstocks 

Finally, principle #7 of the 12 principles of green chemistry is the use of renewable feedstocks, which states that renewable feedstocks should be prioritized over non-renewable ones. “Feedstocks” can encompass a number of chemistry aspects, including the type of energy that is used, the material that storage containers are made out of, and- of course- the chemicals themselves. Renewable chemicals reduce the amount of chemical waste, which has the potential to harm the environment depending on how the waste is disposed of. Hence, this is another principle for which using eco-friendly chemicals is vital.

Understanding the History of Green Chemistry

Are you curious about how the branch of chemistry known as green chemistry originated? This blog post will provide insight into the history of green chemistry, allowing you to learn about its inception and follow its progression to the present day.  

Green Chemistry: The 1960s-1980s 

The initiation of green chemistry can be tracked all the way back to the 1960s when Rachel Carson wrote Silent Spring, a book that discussed the impact of chemicals on the ecosystem. This book was an inspiration to both scientists and the public and served as a forewarning about chemistry’s potential to harm the planet.   

In 1970, the U.S. Environmental Protection Agency (EPA)- a federal regulatory agency dedicated to protecting the health of both humans and the environment- was established by President Richard Nixon. The EPA’s first major mandate banned the use of DDT and other chemical pesticides deemed hazardous.  

In the 1980s, members of the EPA and the chemical industry began to focus less on chemical clean-up and more on preventing chemical pollution from occurring in the first place. This led to the creation of the Office of Pollution Prevention and Toxics in 1988.  

Green Chemistry: The 1990s 

The 1990s was a significant decade for green chemistry. A few of the important events that occurred during these years were: 

  • 1990: The Pollution Prevention Act, which stated that national policies in the United States should focus on preventing pollution rather than mitigating existing pollution, was passed.  
  • 1995: President Bill Clinton aided the EPA in creating an annual awards ceremony, the Presidential Green Chemistry Challenge Awards, which honored scientific advances that bolstered the green chemistry movement.  
  • 1997: The nonprofit Green Chemistry Institute (GCI) was co-founded by Dr. Joe Breen and Dr. Dennis Hjeresen.  
  • 1998: Green Chemistry: Theory and Practice, which outlined the now well-known 12 Principles of Green Chemistry, was published. 

Green Chemistry: Today 

Today, many successful companies whose products are based on the application of green chemistry and engineering have been established. Consumers can now find numerous eco-friendly chemicals, materials, and other industrial products on the market. Essentially every type of business now has a means to significantly reduce its carbon footprint. 

However, the green chemistry movement is still in its beginnings. One way that companies can help to support green chemistry is by purchasing their materials, whatever they may be, from manufacturers that emphasize environmental protection in their products and practices.

water treatment chemicals

Basic Water Treatment Chemicals

Treating water with chemicals is a necessary process for drinking and industrial purposes, that helps to protect the water from contamination, whether from disease-causing germs or hazardous substances. There are many basic water treatment chemicals that are used in treatment processes.

water treatment chemicals

Water treatment methods can use four different processes, which are: 

  • Boiler water treatment 
  • Cooling water treatment 
  • Purification of water 
  • Treatment of wastewater 

Some examples of types or qualities of water treatment chemicals include: 

  • Corrosion and scale inhibitors: 
    • These chemicals are added for the purpose of preventing scale formation, such as calcium carbonate, and corrosion in boilers, washing machines, or any equipment that involves water and has the potential of forming scale deposits.  
    • Some examples of corrosion inhibitor chemicals include phosphate esters or organic phosphonates.  
  • Oxidants: 
    • Oxidants are added to reduce chemical oxygen demand (COD) levels and to remove oxidizable organic/inorganic substances.  
    • Some examples of oxidants used are hydrogen peroxide and ozone.  
  • Oxygen scavengers:  
    • These scavengers are added for the purpose of absorbing oxygen molecules to prevent oxidation reactions from occurring, which can lead to the formation of toxic or undesired byproducts. 
    • Some examples of oxygen scavengers include carbohydrazide or hydroquinone.  
  • Coagulants: 
    • These chemicals are added to wastewater to collect slurry or particles that are not settling into large masses, forming a floc. This process is done to remove the solid particles from the water.  
    • Commonly used coagulants include aluminum sulfate, iron (III) chloride, or iron (III) sulfate 
  • Flocculants: 
    • Flocculation is the process that involves slow mixing of the wastewater to ensure the growth of the floc, improve the filtration and efficiently clean the water.  
    • Common flocculants added for water treatment include activated silica and polyacrylamide.  
  • Anti-microbial: 
    • These types of chemicals are added because of their ability to eliminate bacteria and parasites, to ensure that water is disinfected and safe to drink.  
    • Examples of anti-microbial chemicals added are chlorine, chlorine dioxide, and hypochlorite.
