    As an engineer, your day-to-day responsibilities often include staying up to date on best-in-class applications and specifications. But whether you’re charged with designing a water treatment facility or pump station, or simply supervising an existing system, the equipment you select must be vetted. This is generally a challenge for engineers because many companies are vying to have their products deemed as the best solution, yet visibility into those claims is often limited.

    Zero Liquid Waste: A Desalination Solution For Chloride, Sulfate Limits

    Mining operations and other energy producers face a multitude of clean-water regulations that can seriously impact their businesses. Strict standards governing discharge into waterways can increase costs and inhibit production. Veolia Water Technologies is addressing these issues through advanced treatment processes that allow companies to generate clean water for reuse or environmental discharge with no substantial liquid waste. Called the Zero Liquid Waste (ZLW) approach, the industrial water desalination technology benefits the mining industry, which must contend with stringent new regulatory requirements that limit the discharge of chlorides and sulfates into streams, rivers, lakes and other bodies of water.

  • Organics Monitoring (TOC)

    Total organic carbon (TOC) testing is the traditional method for determining organic matter in water. However there is a far more practical, affordable and often more useful way to measure organic matter. UV absorbance testing (UVA) is rapidly becoming the preferred method of measuring organics even when the levels of organics being measured are very small.

    Hydrogen Sulfide Removal From Water Using AquaSorb® CX-MCA

    The “rotten egg” odor in some water supplies is caused by sulfide in water. Sulfide can be treated using oxidation techniques, the goal being to convert the sulfide to high oxidation state species such as sulfate to eliminate the taste and odor concerns. Traditional oxidation techniques such as ozone and chlorine can be used, but can be expensive due to the equipment required to add and monitor the oxidant, and can lead to by-products such as trihalomethanes (THMs), which are regulated in drinking water supplies.

  • Dissolved Oxygen Measurement
    Dissolved Oxygen Measurement

    One of the most important measurements in the determination of the health of a body of water is its dissolved oxygen content. The quantity of dissolved oxygen in water is normally expressed in parts per million (ppm) by weight and is due to the solubility of oxygen from the atmosphere around us.

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.
