Remote Monitoring Helps Growers, Water Districts Do Their Jobs

Propeller flow meters have long been an important tool for agricultural irrigation management. As water scarcity and resource management have become increasingly critical, getting the most timely, accurate readings available from those meters is becoming more important than ever. Here is how growers and water conservation districts (WCDs) are each getting the best of both worlds for their own purposes.

  • General Electrochemistry
    General Electrochemistry

    All chemical processes involve the loss, gain, or redistribution of electrons on an atom or group of atoms. Electricity is the movement of electrons along a conductor. It is no wonder then that chemical changes can be made to occur by passing an electric current through a solution containing atoms or groups of atoms which will accept or give up electrons. Processes which pass an electrical current through a solution to effect chemical changes are called electrochemical processes. By PEPCON Systems

  • Application Note: Low-Flow Sampling Of Water Quality Parameters Used In Determining Groundwater Stability
    Application Note: Low-Flow Sampling Of Water Quality Parameters Used In Determining Groundwater Stability In April 1996, the U.S. EPA developed and published a document entitled Low-Flow (Minimal Drawdown) Ground-Water Sampling Procedures. The document states that “the most common ground water purging and sampling methodology is to purge wells using bailers or high speed pumps to remove 3 to 5 casing volumes followed by sample collection.” Adverse impacts can occur through this method affecting sample quality by increasing levels of turbidity. These problems can often be mitigated by using low-flow purging and sampling to reduce sampling-induced turbidity. By YSI

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.
