In this section we will, from time to time, offer brief articles written by our staff on various aspects of water treatment. The articles listed below are currently available. Please note that the dates on this page inform you of the latest revision. The article shows the date on which it was printed.
Return Line Treatments - Meeting Shipping and Storage Requirements (Refer to as “RLT”) (03/23/11) Excerpt: For many years, Scranton Associates and its precursor has produced many return line treatments for many customers. We have often been asked for guidance as to the flammability of these end products. Typically they have been dilutions and/or combinations of diethylaminoethanol (DEAE), morpholine (MOR), and cyclohexylamine (CHA). Other materials such as aminomethylpropanol (AMP), triethanolamine (TEA), methoxypropylamine (MOPA), and dimethylamino-2-propanol (DMA-2-P) are used to a lesser degree, but will not be part of this article.
Sulfites for Oxygen Control (Refer to as “SOC”) (09/11/07) Excerpt: Oxygen is present in all water supplies, though at widely varying concentrations. Unless limited, it can cause corrosion throughout the entire steam generation system. In addition to weakening the metal, this attack generates metallic oxides that become or form troublesome deposits. And while oxygen provides a major pitting challenge on its own, additional forms of corrosion are accelerated by its presence.
Saturation, Stability, and Scaling Indices (Refer to as “SSSI”) (10/29/07) Excerpt: Time is short so we will plunge right into this exciting saga of scaling indices, acknowledge their productive uses, uncover their severe limitations, and overlook their frequent misinterpretations. We will present a drama filled with mystery and intrigue where scaling indicator break points are regularly published and tediously described, but where most practitioners use entirely different values. What is more, we must sadly recount a tale of treachery and favoritism where the speaker who discloses these improprieties is allotted less than twenty minutes while the one from Imperial Oil is given forty-five.
Inhibitor Choice & Dosage (Refer to as “ICD”) (10/29/07) Excerpt: Our challenge today is to develop chemical formulas that will control scale in cooling tower waters at the lowest total cost. Sadly and reluctantly, we learned of, and are obliged to expose, those purveyors of phosphonates and polymers who eagerly carry us over the threshold into orgies of short-lived, excessive-treatment bliss. Such high levels have negative consequences that extend far beyond the obvious economic ones and add to our mounting aversion to reckless additions.
Understanding Proper Shipping Names (Refer to as “UPSN”) (10/01/07) Excerpt: Full compliance with the Department of Transportation (DOT) regulations is necessary for the management of any water treatment business. It is both our legal and moral obligation to insure that the products we provide are transported in a safe and environmentally sound manner. We all want to avoid penalties for incorrectly labeling and describing the products we ship. In addition, your end users deserve assurance that they will not be deemed negligent in the event of an accident or spill, and you are expected to properly warn and advise them.
Formula Development - Cooling Water Treatments (Refer to as “FDCWT”) (10/01/07) Excerpt: Sufficient information is included in this paper for a water treatment engineer to design, manufacture, and apply scale and corrosion control remedies throughout a wide range of conditions. The proposed program is unique in that blending instructions for 55 gallon quantities end up with whole number quantities for each ingredient, making the production of such small batches easier. And it’s just fine for larger batches too!
