WATER TREATMENT INDUSTRY IN UNITED STATES OF AMERICA
INTRODUCTION
Drinking water supplies in the United States are among the safest in the world.
However, even in the U.S., drinking water sources can become contaminated, causing
sickness and disease from waterborne germs, such asCryptosporidium, E. coli,
Hepatitis A,Giardia intestinalis, and other pathogens.
Drinking water sources are subject to contamination and require appropriate treatment
to remove disease-causing agents. Public drinking water systems use various
methods of water treatment to provide safe drinking water for their communities.
Today, the most common steps in water treatment used by community water systems
(mainly surface water treatment) include:
Coagulation and Flocculation
Coagulation and flocculation are often the first steps in water treatment.
Chemicals with a positive charge are added to the water. The positive charge of
these chemicals neutralizes the negative charge of dirt and other dissolved
particles in the water. When this occurs, the particles bind with the chemicals and
form larger particles, called floc.
Sedimentation
During sedimentation, floc settles to the bottom of the water supply, due to its
weight. This settling process is called sedimentation.
Filtration
Once the floc has settled to the bottom of the water supply, the clear water on top
will pass through filters of varying compositions (sand, gravel, and charcoal) and
pore sizes, in order to remove dissolved particles, such as dust, parasites,
bacteria, viruses, and chemicals.
Disinfection
After the water has been filtered, a disinfectant (for example, chlorine,
chloramine) may be added in order to kill any remaining parasites, bacteria, and
viruses, and to protect the water from germs when it is piped to homes and
businesses.
Water may be treated differently in different communities depending on the
quality of the water that enters the treatment plant. Typically, surface water requires
more treatment and filtration than ground water because lakes, rivers, and streams
contain more sediment and pollutants and are more likely to be contaminated than
ground water.
Demand for water treatment equipment in the US is forecast to grow 5.9 percent
per year to $13.0 billion in 2017.

Some water supplies may also contain disinfections by-products, inorganic chemicals,
organic chemicals, and radionuclides. Specialized methods for controlling formation or
removing them can also be part of water treatment.
Some common, market opportunities exist across geographic boundaries to one degree
or another. The states and nations need solutions to problems of:
• Insufficient water quantity and/or quality
• Available water resources not being where demand for water is located
• Wastewater treatment expansions and upgrades
• Energy costs playing an increasingly important role in water decisions
• Water policies not keeping up with the changing water needs
• Resistance to change, be it in policies or practices
• Insufficient monetary resources allocated to addressing water needs
Water Quality Regulations in the United States
The EPA, under the requirements of the SDWA, regulates drinking water in the United
States. The EPA additionally regulates wastewater, but under the requirements of the
Clean Water Act (CWA). Storm water and discharges into surface water are also
regulated under the CWA.
The SDWA sets maximum contaminant levels (MCLs) and treatment techniques (TTs)
that drinking water must meet to be considered safe for consumption. The list includes
microorganisms, disinfectants and disinfection by-products, inorganic chemicals,
organic chemicals, and radionuclides.

wastewater treatment. One such example is the Quadrasperse product line, which
controls calcium phosphate, calcium carbonate, magnesium silicate and iron deposits in
high-stress boiler and cooling water applications, allowing the customers to increase
their cycles of concentration, generate substantial cost savings, and increase system
performance.
RAW AND WASTEWATER TREATMENT CHEMICAL PROGRAMS
ChemTreat’s chemical programs for raw water and wastewater treatment are for the
removal of suspended and dissolved solids from both industrial influent and effluent
waters. These programs are custom-designed to help the customers protect their
systems and the environment, as well as comply with state and government discharge
regulations.
INFLUENT AND EFFLUENT TREATMENT:
The solid-liquid separation programs are needed to prevent the build-up of solids in
industrial systems. These programs are designed to maximize system efficiency, and
prevent any damage or down-time to equipment.
