Drinking Water Treatment Applications

Arsenic Removal from Drinking Water

Arsenic water filtration takes place in many communities where arsenic has been detected at dangerous levels in public drinking water supplies.

Desalination Pretreatment

Desalination is a viable option for coastal communities. Evoqua is dedicated to research and development of energy-savings, chemical free technologies and the reduction of waste discharges that result for this process.


Disinfecting public water supplies is nothing new. However, with various disinfection technologies, emerging contaminants, and new regulations to consider, choosing the right drinking water disinfection method can be an overwhelming task.

Disinfection By-Products Removal

DBPs are present in most drinking water supplies that have been subject to chlorination, chloramination or ozonation. Exposure to DBPs in drinking water has been associated with human cancers and some adverse birth defects.

Dissolved Metals Removal from Drinking Water

Many dissolved metals have been found in harmful concentrations in groundwaters destined for potable drinking water due to both naturally occurring contamination as well as contamination introduced from industrial pollution.

Drinking Water Clarification and Filtration

Water filtration is central to the treatment of source water for drinking water applications. We have filtration products to help engineers and operators create successful solutions for drinking water systems.

Drinking Water Fluoridation

Fluoridation is the process by which fluoride is added to drinking water for the purpose of preventing tooth decay. At the extremely low levels of fluoride being dosed and measured, precision and reliability of the dosing system are required.

Hexavalent Chrome Removal From Drinking Water

Though widely distributed in soil, chromium is not common in natural waters. Rather, it’s presence occurs in surface waters destined for potable drinking water use as a result of improper wastewater treatment from industrial pollution.


Hydrogen sulfide removal in drinking water is not carried out due to a health hazard but because hydrogen sulfide is a common nuisance contaminant whose distinctive "rotten egg" odor makes water treatment desirable.


The EPA has publicly expressed concern over the current and future mercury concentration levels in lakes and rivers resulting from industrial water emissions and land disposal and the net impact of human exposure.

Perchlorate Removal from Drinking Water

Perchlorate salts are man-made compounds used as combustion accelerants, in some munitions, fireworks, road flares. Manufacturing waste and improper disposal are increasingly being found in groundwater and local drinking water wells.

System Automation and Control

As water and wastewater treatment and process technologies continue to improve it takes complex integrated controls and telemetry systems to take advantage of their full potential.

Taste and Odor Control

Many municipalities seek to control taste and odor issues to minimize consumer complaints and for aesthetic reasons versus health-based regulations.

Drinking Water TOC Reduction

Drinking Water TOC Reduction is required when disinfection byproducts such as Trihalomethane (THM) exceed federal and state regulations.

Drinking Water Treatment VOC Removal

Drinking water containing high levels of volatile organic compounds (VOCs) may be harmful to human health. At high levels of exposure, many VOCs can cause central nervous system depression (drowsiness, stupor).

Drinking Water Treatment Water Quality Analyzers and Process Control

Keep up with increased regulatory and quality control drivers that require better analytical and control techniques to stay within regulated, permitted and/or control limits. See how...


Water softening is employed to reduce hardness, suspended solids, silica and other potential foulants in water supplies.
