DRINKING WATER

The Benefits Of Reusing Wastewater

Since water is an essential element in food or beverage operations, reusing it can reduce a business’s water usage ratios, help meet sustainability goals, lower supply risk and contribute to cost savings, making it a top priority for many companies today.

    White Paper: The Leopold® Clari-DAF™ System For Membrane Pretreatment The idea that membranes could be used for solids removal and concentration in potable water treatment schemes has been known for hundreds of years. It has only been in the past 50 years or so that reverse osmosis membranes for treating brackish waters or sea water have been considered a cost-effective viable alternative. More recently, the membrane suppliers have produced low-pressure membranes that are applied in current treatment process schemes to enhance the water quality effluent required to meet additional regulatory guidelines

    The Roche Harbor Water Treatment Plant is located on the northwest side of San Juan Island in San Juan County, Washington state. Although a significant part of the land in the county is privately owned, the watersheds there provide a public benefit for both residents and visitors.  San Juan Island’s economy is tourist-driven; the island was voted #2 on the New York Times list of “41 Places to go in 2011.” Its marina has been a top boating destination for more than fifty years. Incorporated in 1886, the community has seen slow but steady population growth in recent decades. Roche Harbor Water System Inc. has been in operation since 1968 when PVC piping replaced the island’s existing wooden pipe system.

    Concrete Manufacturing Operation Meets Permit Requirements With PH Control System

    In order to meet its discharge permit limits, a ready-mix concrete manufacturing operation needed to neutralize its high pH process water. Staff installed a control system that automatically detects a rise in pH and treats the water with a modular in-line carbon dioxide feed system. The operation can now recycle treated water for rinsing trucks, supply recycled water into the concrete batching operation, and safely discharge the water into the environment.

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.
