Chemical Cleaning


Chemical cleaning is a method to derive surfaces and walls of equipment, pipelines, vessels, kettles, and heat exchangers of unwanted contaminants. Chemical cleaning also means the purification, conditioning, treatment, or disinfection of water.

Here, we will provide you with an overview of all chemical cleaning methods and their applications. We will also name alternatives and environmentally friendly solutions.

  • Limestone removal and scaling prevention for heat exchangers, pipelines, and kettle walls
  • Biofilm removal for equipment that has been in touch with water
  • Legionella disinfection
  • Surface disinfection and suture activation with UV-radiation
  • Ozone disinfection and oxidation for several applications
  • Surface corrosion treatment
  • Scent removal off walls, pipelines
  • Corrosion prevention in CV-pipes, aluminum silo, and systems with various materials


Legionella control


Legionella Control
Legionella Control


In the prevention and control of legionnaires disease (legionella) causing microbes, chlorine dioxide has taken an eminent role. The specific characteristics of the disinfectant make sure ClO2 gets the job done where others fail.

Biofilm in the piping can protect legionella from most of the disinfectants. Chlorine dioxide, however, removes the biofilm and kills bacteria, spores, and viruses.


Corrosion treatment


Anti-Corrosion Treatment
Anti-Corrosion Treatment


Corrosion treatment is a kind of water treatment that serves the prevention of corrosion in plumbing systems of various materials, such as rustproof steel, carbon steel, copper, and aluminum.


Open plumbing systems


An “open system” means that the water in a plumbing system can come in contact with outside air and, as a result, with oxygen. The system is open because of a connection with an open storage barrel or a vertical pipe. Oxygen dust or contaminants may be added to the system in time through the openings.

Oxygen and contaminants that are added to the system can enhance microbial activity. Consequentially biofilm formation may occur. This may cause negative effects, such as slime formation and stuffing of pipes and heat exchangers.

The MACK Group can offer various solutions to these problems, for instance, UV-disinfection, ozonization, bio dispersant dosing, and other chemical solutions.


Sampling equipment and measurements


The MACK Group can supply companies with various test sets for the monitoring of several parameters, such as pH, conductivity, hardness, microbial contamination, and inhibitor concentrations.

If you would like us to advise you on the situation of your plumbing system and the steps you can take to remove and prevent corrosion, please send us an overview of the arrangement of your system and your water analysis.

If necessary we could perform water analyses for you.


Chemical Remediation


In situ chemical oxidation (ISCO), a form of advanced oxidation processes and advanced oxidation technology is an environmental remediation technique used for soil and/or groundwater remediation to reduce the concentrations of targeted environmental contaminants to acceptable levels.


Environmental remediation deals with the removal of pollution or contaminants from environmental media such as soil, groundwater, sediment, or surface water. Remedial action is generally subject to an array of regulatory requirements, and may also be based on assessments of human health and ecological risks where no legislative standards exist, or where standards are advisory.

Chemical Decontamination


What is chemical decontamination?

Decontamination (sometimes abbreviated as decon, dcon, or decontam) is the process of cleansing an object or substance to remove contaminants such as micro-organisms or hazardous materials, including chemicals, radioactive substances, and infectious diseases.


The purpose of decontamination is to prevent the spread of micro-organisms and other noxious contaminants that may threaten the health of human beings or animals, or damage the environment.

Relocating, downsizing, or shutting down a laboratory can feel daunting. Years of experiments lead to an accumulation of chemicals that require appropriate handling and disposal and equipment that must be decontaminated and decommissioned. Workspaces must also be decontaminated before being vacated. Opting for decontamination and decommissioning service providers with the ability to design a custom plan based on your lab’s specific needs while adhering to health and safety requirements ensures a smooth transition.

Coronavirus Biological Cleaning


The worldwide novel Coronavirus (COVID-19) outbreak has people scrambling to protect themselves, their homes, and businesses from potential contamination. The effects of this type of biohazard situation can last up to a week and the continued spread of the disease has led to a growing number of fatalities in the US.



The MACK Group, LLC is the industry leader in Environmental remediation, including coronavirus disinfection, and delivers the highest professional standards possible. We are dedicated to providing rapid emergency response 24/7 throughout the US so you can have peace of mind in the event of an outbreak.


How does The MACK Group, LLC clean Coronavirus?


Coronavirus Cleaning

Coronavirus has quickly gained a reputation for being particularly insidious. It can survive on surfaces for up to 17 days and people infected by the virus don’t show symptoms until approximately two weeks after infection, making it difficult to track and contain. This is why having a trusted professional disease and biohazard remediation company on your side is so important.

The MACK Group, LLC adheres to all OSHA regulations and strictly follows the most state-of-the-art procedures when it comes to disease cleanup and disinfection. Coronavirus (COVID-19) is still novel, so we continually consult with the Centers for Disease Control & Prevention (CDC) for up-to-date solutions on Coronavirus and utilize CDC-approved and EPA-registered disinfectants.




  • We use CDC approved and EPA registered industrial-strength disinfectants with a broad spectrum kill claim
  • All infected materials are cleaned, disinfected, and properly disposed of as biohazard waste
  • Fully encapsulated personal protective equipment (PPE) and full-face respirator masks are worn at all times by our certified cleanup technicians
  • We adhere to a stringent coronavirus demobilization process for our equipment, trucks, and waste storage areas

A disease outbreak is an extremely serious situation and we understand that the health and safety of you, your family, and your employees are on the line. Don’t take any chances; Contact The MACK Group, LLC.




The MACK Group, LLC has designed a remediation process to protect the health and safety of our customers and their property.

Steroid Decommissioning

Decommissioning (also called abandonment) is the process by which the owner-operator of an offshore oil or gas installation will plan, gain approval for, and implement the removal, disposal, or reuse of installation when it is no longer needed for its current purpose.


What Does Decommissioning Mean?


Decommissioning can be defined in different ways by different companies, but for the MACK Group, LLC it predominantly refers to our work involved in the scheduled shut-down and ceasing of operations of Industrial, Chemical, Petrochemical, Power, or Nuclear facilities.

Demolition of structures or buildings can sometimes be referred to as decommissioning, and these two elements of our business often coincide and collaborate on large-scale Industrial, Chemical, Petrochemical, Power, or Nuclear projects.


What does decommissioning consist of?


Principally though, decommissioning works for The MACK Group, LLC constitutes the following:
The works involved in decommissioning Industrial, Chemical, Petrochemical, Power, or Nuclear facilities or plants encompass a detailed process and, like the demolition works that often follow on such projects, require defined surveying, planning, and management throughout the works.


Decontamination and industrial cleaning


Decontamination and industrial cleaning of elements such as plant, machinery, equipment, and pipework within a facility is often the first phase of work. Only once this is completed and the areas signed off can the strip-out and removal phase of the decommissioning work begin.
