The Mechanics of Filtration

The Mechanics of Filtration Commercial and industrial filtration systems fall into two broad categories: surface filters and depth filters. Essentially, filtration is accomplished by either surface and depth filters or by electrostatic attraction of undissolved particles in water to certain types of filter media. Figure 1-2 Surface (screen) Filtration Surface filtration can be described as [...]

Understanding Different Types of Filter Elements

Understanding Different Types of Filter Elements While the spectrum of available cartridge elements is very broad, going from coarse grit removal types at 100 micron rating to very fine filter elements of the 1.0 micron rating used for reverse osmosis pretreatment, the bulk of units fall into two major categories: (1) sediment removal and (2) [...]

The Troublesome Trio & Water Purity: Part 2

The Troublesome Trio & Water Purity: Part 2 Part 2: Manganese & Hydrogen Sulfide Three undesirable water characteristics-iron, manganese, and hydrogen sulfide--can he called the "Bermuda Triangle" of the water processing business. Singularly or in combination, this trio can present a very complex challenge to the water treatment specialist. The same processing method used for [...]

Singularly or in combination, this trio can present a very complex challenge to the water treatment specialist. The same processing method used for removal of one species [...]

Understanding Boiler Operation

Understanding Boiler Operation One of the most common water softener applications is for softening the supply water to steam boilers. Most industrial and many commercial establishments require steam. Steam is used in textile mills to produce, form, and dye fabrics. The dry cleaner uses steam to iron linens. Canneries and meat packers cook or process [...]

Water – The Problem of Purity

Water – The Problem of Purity In its pure state, water is one of the most aggressive solvents known. Called the “universal solvent,” water, to a certain degree, will dissolve virtually everything to which it is exposed. Pure water has a very high energy state and, like everything else in nature, seems to achieve energy [...]

Identifying Specific Water Impurities

Identifying Specific Water Impurities Specific Impurities Many individual impurities can be quantified through water analysis techniques. Below is a discussion of most ionic individual contaminants. Water Hardness The presence of calcium (Ca2+) and magnesium (Mg2+) ions in a water supply is commonly known as “hardness.” It is usually expressed as grains per gallon (gpg). Hardness [...]

Identifying Water Impurities

Identifying Water Impurities The impact of the various impurities generated during the hydrologic cycle and/or bacterial colonization depends upon the water user’s particular requirements. In order to assess the need for treatment and the appropriate technology, the specific contaminants must be identified and measured. Qualitative Identification Qualitative identification is usually used to describe the visible [...]

Pharmaceutical Water Treatment Experts

Pharmaceutical Water Treatment Experts The pharmaceutical industry requires the purest of water to ensure that regulations are met and products are produced without the risk of introducing contaminants that could potentially result in illness and/or product recalls. Are you willing to risk the expense of that situation, or are you ready to speak to the [...]

Selecting the Perfect Filter Cartridge

Selecting the Perfect Filter Cartridge As a distributor of water treatment supplies, we are often asked to provide filter cartridges. Most of the time, these requests consist of the client saying: "Hey, I need a 5 micron 20" long cartridge." Sounds simple enough; however, there's more to a filter cartridge than the just these two  [...]

The Advantages of RO Water in Finishing Systems

The Advantages of RO Water in Finishing Systems The powder coating industry demands quality water to clean and rinse parts. By using reverse osmosis (RO) technology, finishers have found ways to help reduce water consumption and the overall volume of wastewater in their plants. In addition, purified RO water leads to better finish quality, huge [...]

RO Membrane Scaling: What to Do?

RO Membrane Scaling: What to Do? Click the image above to view a scaling case study! Click the image above to view a scaling case study! RO Scaling Scales are formed when dissolved substances in the feed water reach their maximum solubility limit somewhere in the RO unit. When further concentrated, they precipitate out of [...]
