DRINKING WATER TREATMENT

New Membrane Technology Handles High Solids, Aids Water Reuse

As global conditions place more stress on water resources, a great deal of attention is being paid to water reuse technologies, particularly those that facilitate the reuse of the next level of difficult-to-treat or highly variable raw water sources.

  • Biological Filtration For Iron And Manganese Removal

    In an earlier papers, the author reviewed the physical-chemical processes conventionally used to remove iron and manganese from groundwater and explained how the process most commonly used in France (aeration + 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.

    The term wastewater can be applied to a wide range of water sources from municipal sewage to storm runoff to industrial discharge water. By Michael Sheedy, Vice President of Technology and George Di Falco, Marketing Communications, Eco-Tec Inc.

  • Membranes Deserve Multi-Stage Protection Membranes are extraordinarily effective at water purification at the sub-micron level – which is exactly why they need to be protected from particulate contamination. Membranes last longer, operate more productively, and require fewer cleaning cycles when they are shielded from the silt, sand, fibrous material, algae, bacteria, mollusk larvae, scale, and the other contaminants that can cripple millions of dollars’ worth of membranes in weeks or even days. Multi-stage filtration can be both efficient and cost-effective in protecting membranes

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.
