Ion Exchange Articles

Essentials of Ion Exchange; Natural water supplies contain dissolved salts, which dissociate in water to form charged particles called ions. These ions are usually present in relatively low concentrations and permit the water to conduct electricity. They are sometimes referred to as electrolytes. These ionic impurities can lead to problems in cooling and heating systems, steam generation, and manufacturing. The common ions that are encountered in most waters include the positively charged cations; calcium and magnesium (hardness forming cations, which make a water "hard") and sodium. The negatively charged anions include alkalinity, sulfate, chloride, and silica. Ion exchange resins are particularly well suited for the removal of these ionic impurities... .

Removing Organics with Ion Exchange Resin; Organic materials can cause unwanted tastes, colors or odors in potable water supplies, and can stain clothes washed in water containing these compounds. Chemically these substances are iodized by chlorine or ozone, after which the water is passed through granular activated carbon. However, chlorine or ozone systems may not be the most convenient choice for small home units... .

Common Pitfalls of Ion Exchange for Organic Traps; Organic traps are used primarily in two applications—color removal from drinking water and as protection for demineralizers to reduce fouling. The following article is not so much a "how to" piece on how to design such traps but rather a discussion of common problems and how to avoid them, with respect primarily to color removal. Fouling with organics is a separate issue not discussed here.

Ozone Articles

Air Treatment With Ozone; Much has been said about the sick building syndrome and this usually refers to institutional buildings. But they have basically the same problems as the private home. People exposed to such conditions suffer from symptoms of environmental toxicity. 

EPA Safety Guidelines; Recommended Exposure Limits, Ambient Ozone Concentration Monitors

Flood Damage Restoration; Ozone is the perfect solution for flood damage restoration.

Milestone Event - Ozone for Food Processing; EPRI Files Food Additive Petition for Ozone as An Antimicrobial Agent

Opportunities and Uses for Ozone; Explore some of the many uses for ozone.

Ozone Defined; A Definition of how Ozone is created and more interesting facts about Ozone.

Ozone Gets OK For Use In US Food Industry; Ozone, one of the most effective disinfectants used in food processing in other countries, has received "Generally Recognized As Safe" (GRAS) status in the United States from a panel of experts in the food science, ozone technology, and other related fields.

Ozone Pilot Plant Design; This article addresses practical design considerations for building an Ozonation Pilot Plant.

Successful Treatment Using Ozone in Potable Water; Information Gathering, Determining the Ozone Demand, Determine Equipment and Chemical Needs, System Designs.

Waste Water Treatment Systems; Full scale waste water treatment systems for water recovery in fish hatcheries and farms, domestic, municipal and commercial sewer systems, liquid waste from food processing, and industrial toxic waste.

Reverse Osmosis Articles

Reverse Osmosis Theory; Reverse Osmosis is a process in which a semipermeable membrane is used to separate fluids of various qualities into a highly saturated concentrate (brine) and a high quality permeated fluid low in dissolved solids. The separation is accomplished by passing the fluid across the membrane at a specified pressure and velocity.

Technical Articles

Chemical Oxygen Demand (COD); Biochemical Oxygen Demand (BOD) is a definitive indicator of required treatment in wastewater, and estimating BOD is an important part of wastewater treatment process control. The U.S. Environmental Protection Agency (USEPA) requires wastewater treatment plants to bring BOD within limits before discharging treated wastewater, and accurate test results must be recorded for regulatory reporting. Thus, measuring BOD in treated water is an important part of the monitoring process. Many wastewater treatment facilities use a faster Chemical Oxygen Demand (COD) test to estimate BOD levels... .

General pH Theory; pH is a unit of measure which describes the degree of acidity or alkalinity of a solution. It is measured on a scale from 0 to 14. The term pH is derived from “p”, the mathematical symbol of the negative logarithm, and “H”, the chemical symbol of Hydrogen.

General Conductivity Theory; Conductivity is defined as the ability of a substance to conduct electric current, which is the reciprocal of resistivity. All substances posses conductivity to some degree, but the amount varies widely, ranging from extremely low (insulators such as glass or benzene) to very high (silver, copper, and metals in general).
