    Case Study: Biological Filtration For Iron And Manganese Removal

    In an earlier paper, the author reviewed the physical and chemical processes conventionally used to remove iron and manganese from groundwater, and explained how the process most commonly used in France (aeration plus filtration) led to the discovery of coincident biological phenomena. These were subsequently applied to enhance the performance of certain existing units and, especially, to serve as a basis for a new generation of biological treatment plants offering sharply improved performance levels. These general considerations will be illustrated by a number of examples, selected from among nearly 200 existing facilities. By Pierre Mouchet, Manager of Technical Assistance and Information

  • Case Study: Water Supplier Ensures DBP Compliance With UV254 Organic Monitoring
    Case Study: Water Supplier Ensures DBP Compliance With UV254 Organic Monitoring Mohawk Valley Water Authority (MVWA) is a progressive supplier of potable water. With source water from the Adirondack Mountains, MVWA works to improve on nature and provide superior water quality, always striving to meet or exceed drinking water standards. Like many other surface water sources, MVWA’s water supply is rich with natural organic matter (NOM). Unfortunately, growing research has demonstrated that NOM in water when combined with chlorine leads to the formation of potentially harmful disinfection by-products.
  • From Well Above To Far Below MCLs: AdEdge Oxidation/Filtration Tames Arsenic And Iron

    In November 2009, AdEdge Water Technologies, LLC was contacted by Great West Engineering to provide an arsenic and iron removal system for the Gore Hill County Water Treatment Plant Wells #1 and #2 in Great Falls, Montana.

  • Meet (Or Beat) EPA Nitrate MCLs With An AdEdge Packaged Nitrate Removal System

    When a food processing plant in Lancaster County, PA was forced to supply bottled water to its employees due to high nitrate levels in its raw water, they had no choice but to investigate a nitrate removal solution. In this case study you’ll learn how the plant avoided EPA violations by reducing nitrate contamination levels to below 8 mg/L and simplified continuous monitoring by implementing a new packaged nitrate removal system from AdEdge.

ABOUT DRINKING WATER TREATMENT

Drinking Water Treatment involves the removal of pathogens and other contaminants from source water in order to make it safe for humans to consume. Treatment of public drinking water is mandated by the Environmental Protection Agency (EPA) in the U.S. Common examples of contaminants that need to be treated and removed from water before it is considered potable are microorganisms, disinfectants, disinfection byproducts, inorganic chemicals, organic chemicals and radionuclides.

There are a variety of technologies and processes that can be used to decontaminate or treat water in a drinking water treatment plant before the clean water is pumped into the water distribution system for consumption.

The first stage in treating drinking water is often called pretreatment and involves screens to remove large debris and objects from the water supply. Aeration can also be used in the pretreatment phase. By mixing air and water, unwanted gases and minerals are removed and the water improves in color, taste and odor.

The second stage in the drinking water treatment process involves coagulation and flocculation. A coagulating agent is added to the water which causes suspended particles to stick together into clumps of material called floc. In sedimentation basins, the heavier floc separates from the water supply and sinks to form sludge, allowing the less turbid water to continue through the process.

During the filtration stage, smaller particles not removed by flocculation are removed from the treated water by running the water through a series of filters. Filter media can include sand, granulated carbon or manufactured membranes. Filtration using reverse osmosis membranes is a critical component of removing salt particles where desalination is being used to treat brackish water or seawater into drinking water.

Following filtration, the water is disinfected to kill or disable any microbes or viruses that could make the consumer sick. The most traditional disinfection method for treating drinking water uses chlorine or chloramines. However, new drinking water disinfection methods are constantly coming to market. Two disinfection methods that have been gaining traction use ozone and ultra-violet (UV) light to disinfect the water supply.
