  • Membrane Treatment Of Groundwater

    The groundwater that a southern Louisiana water utility supplies to local residents has traditionally carried a high amount of organic material and color. In the past, the organics were oxidized and broken down by chlorination, but this practice had gone out of favor due to production of disinfection by-products (DBPs) such as Trihalomethanes (THMs) and Haloacidic Acids (HAAs).

    Arsenic Removal Pilot Study Meets California Standards

    Well water from several locations in Ridgecrest, California area is high in arsenic, carbonates and pH. Due to the high levels of arsenic, some wells are not being used to supply municipal water to the city of Ridgecrest and were shutdown. Due to local demand, the feasibility of treating these wells to remove most of the arsenic before blending with water from other wells is being investigated.

  • Making Turbidity Readings Consistent, Reliable, And Compatible

    When water treatment plant (WTP) instrument readings impact regulatory compliance, any discrepancy between laboratory and inline instrument readings can be disconcerting. Fortunately, improved sensor technologies and Mobile Sensor Management capabilities can enhance operator confidence in managing the significance of those readings throughout WTP processes.

  • How To Turn Data Into A Difference-Maker
    How To Turn Data Into A Difference-Maker

    With the proliferation of sensors, data collection, and cloud storage, there is the potential for operational insight heretofore never available, and the opportunity will only expand as the technology evolves and the Internet of Things becomes, well, more of a thing. But data is only truly useful if it informs decision-making that results in positive impact — for an organization's bottom line, its personnel, its customers, or even the world at large (i.e., the environment).

  • How To Use ATP And DNA In A Wastewater Nitrification Monitoring Plan
    How To Use ATP And DNA In A Wastewater Nitrification Monitoring Plan

    Ammonia removal is a key metric for assessing wastewater treatment facility performance. This is because ammonia contributes to aquatic life toxicity. Furthermore, nitrogen, along with phosphorus, is a driver of receiving water eutrophication. Eutrophication, which simply is an over-enrichment of nutrients, can be detrimental to environmental and public health. It can result in harmful algae blooms, dissolved oxygen depletion, fish kills, and other damaging impacts.

    What Are The Environmental Considerations Of A Seawater Treatment Plant?

    A seawater treatment plant was designed as one of the solutions to the recent water scarcity problems. Fresh and drinkable water isn’t easy to find in some places. As the world’s population grows and industrial production increases, even the largest of the world’s freshwater sources can eventually become strained. Therefore, desalination is meant to expand our sources of water across the world.

    Analyzing Water Quality Parameters When Choosing AOP Systems For Water Treatment

    In water and wastewater treatment, chemistry is king. Treatment options are evaluated depending on the quality of water to be treated and the treatment application. Treatment systems including AOP systems, are designed to specifically target certain contaminants and remove or reduce them from the water. This takes places through the power of chemical reactions. Even biological treatments involve chemistry at their core.

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.
