DRINKING WATER PRODUCTS

Aria FAST mobile water units deliver the water you need, when and where you need it. Our mobile systems are easily installed and produce highquality water in as little as four hours after utility connections are complete.

With all the environmental challenges facing us today, doing everything we can to conserve and preserve our water is imperative. As you know, tens of thousands of leaks go undetected, equating to a staggering 6 billion gallons of water loss daily in the United States. To help combat this water loss, we have developed a program that provides you with the tools and knowledge to help find those undetected leaks. Our program is Leak Detection Pilot Program, and we want to partner with you.

Environmental protection, consistent product quality, process optimization and safety –​ just a few reasons why liquid analysis is becoming increasingly essential. Liquids such as water, beverages, dairy products, chemicals and pharmaceuticals have to be analyzed day in and day out. We support you in fulfilling all these measuring tasks with application know-how and cutting-edge technologies. Discover our comprehensive portfolio and choose the product best suited to your process needs.

This video gives an overview of the features and benefits of the YSI Professional Plus, or Pro Plus, handheld multiparameter water quality instrument.

As utilities worldwide face mounting pressure from drought, water scarcity, and tightening regulations, this webinar explores how validated, chemical-free UV solutions are reshaping disinfection across surface water, wastewater, desalination, and potable reuse.

The Eclipse i-Series model #9800i-GENESIS is the newest Intelligent Flushing & Monitoring Station Kupferle offers to maintain safe residual levels and remove DBPs from consumers' water. This permanently installed station incorporates a built-in chlorine analyzer to measure and record disinfectant residual levels based on a programmed sampling schedule.

Water and energy are inextricably linked, yet in our 20th-century water systems we use freshwater once then throw it away. With innovations designed to enhance desalination technologies, agricultural runoff, produced water from industry, and inland brackish groundwater that are now seen as untreatable could all be sources of clean, safe, and affordable water.

Lead poisoning water service lines are turning up around the globe at an alarming rate leaving millions angry. ePIPE's innovative technology creates a new pipe barrier inside the service lines eliminating water contact with the lead service lines.

ABOUT DRINKING WATER

In most developed countries, drinking water is regulated to ensure that it meets drinking water quality standards. In the U.S., the Environmental Protection Agency (EPA) administers these standards under the Safe Drinking Water Act (SDWA)

Drinking water considerations can be divided into three core areas of concern:

  1. Source water for a community’s drinking water supply
  2. Drinking water treatment of source water
  3. Distribution of treated drinking water to consumers

Drinking Water Sources

Source water access is imperative to human survival. Sources may include groundwater from aquifers, surface water from rivers and streams and seawater through a desalination process. Direct or indirect water reuse is also growing in popularity in communities with limited access to sources of traditional surface or groundwater. 

Source water scarcity is a growing concern as populations grow and move to warmer, less aqueous climates; climatic changes take place and industrial and agricultural processes compete with the public’s need for water. The scarcity of water supply and water conservation are major focuses of the American Water Works Association.

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 for contaminant removal and the removal of pathogens 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.

Drinking Water Distribution

Drinking water distribution involves the management of flow of the treated water to the consumer. By some estimates, up to 30% of treated water fails to reach the consumer. This water, often called non-revenue water, escapes from the distribution system through leaks in pipelines and joints, and in extreme cases through water main breaks.

A public water authority manages drinking water distribution through a network of pipes, pumps and valves and monitors that flow using flow, level and pressure measurement sensors and equipment.

Water meters and metering systems such as automatic meter reading (AMR) and advanced metering infrastructure (AMI) allows a water utility to assess a consumer’s water use and charge them for the correct amount of water they have consumed.
