    The Role of Organophosphates in Cooling Water Treatment Introduction: Cooling Water is used in large industries to remove unwanted process heat with the help of heat exchangers, condensers. Due to the continuous contact of water with the metallic surface corrosion, scale, deposition & fouling File Size: KB. Cooling Water Treatment. Cooling towers are used widely due to their optimal cooling technology for industrial processes and HVAC applications. Water shortages combined with increased water usage have combined to decrease the availability and increase the cost of high quality makeup water for cooling tower .

Fouling characteristics of cooling tower water containing corrosion inhibitors by Elisabeth Santoso Download PDF EPUB FB2

The fouling characteristics of cooling tower water containing various corrosion inhibitors and other additives on heat transfer surface have been investigated. Corrosion inhibitors investigated included. • Application of chemical corrosion inhibitors Fighting Microbiological Fouling Cooling water systems are constantly inoculated with microbes from the makeup water, process contamination and the air.

Controlling microbiological fouling depends upon effective control of all these parameters: Water quality—organic contaminants File Size: 2MB.

Author(s): Published: Abstract: Corrosion inhibitors are often added to cooling tower water to prevent the corrosion of the various metallic elements of the cooling water system.

These are effective in preventing corrosion; however, they can, under some circumstances, be the source of fouling in the heat. Hence a comprehensive cooling water additive composition consists of anti-scaling agents, polymeric dispersants and biocides along with corrosion inhibitors to protect Fe, Cu, Al and their alloys [3] [4].

There is a synergistic relationship among the three major cooling water treatment issues: corrosion, scale or deposit formation, and microbiological fouling.

Corrosion inhibitors are often added to cooling tower water to prevent the corrosion of the various metallic elements of the cooling water system.

These are effective in preventing corrosion; however, they can, under some circumstances, be the source of fouling. This chapter is a review of various corrosion inhibitors applicable in water cooling systems.

It discusses some theoretical and practical aspects of corrosion inhibition of metals in aqueous media. The most widespread types of corrosion inhibitors, inorganic and organic, and their corrosion Cited by: 3.

For industrial companies using a cooling tower for its facility, some type of cooling tower water treatment system is usually necessary to ensure an efficient process and long equipment service life.

If cooling tower water is left untreated, organic growth, fouling, scaling, and corrosion. Scale, in addition to causing physical blockage of piping, equipment, and the cooling tower, also reduces heat transfer and increases the energy use.

For example, the thermal conductivity BTU/ [hr. Corrosion in simple terms is the deterioration of materials (primarily metallic) from chemical or electrochemical reactions. Corrosion in industrial water systems is managed by using mild steel inhibitors.

In open recirculating cooling systems, continual replenishment of oxygen as the water passes over the cooling tower makes deaeration impractical. Corrosion Inhibitors. A corrosion inhibitor is any substance which effectively decreases the corrosion. @article{osti_, title = {The effect of copolymer and iron on the fouling characteristics of cooling-tower water containing corrosion inhibitors}, author = {Abu-Al-Saud, A.A.}, abstractNote.

The purpose of a cooling tower is to conserve water. Cooling towers fulfill this purpose by rejecting waste heat to the atmosphere by evaporative cooling and then recycling the water back to the point of heat exchange where the cycle is repeated.

As this process of evaporation and recycling continues, the cooling tower. A literature survey of water-side fouling applicable to cooling tower condensers Article in Proceedings of the Institution of Mechanical Engineers Part A Journal of Power and Energy (7) Keywords: corrosion in cooling tower, carbon steel corrosion, corrosion inhibitor of cooling tower.

Introduction The term “corrosion” (in a cooling water system) is defined as the electrochemical deterioration of a metal that is in contact with cooling water. Corrosion. Cooling Tower Corrosion Inhibitors. Corrosion inhibitors are chemical compounds, organic and inorganic, that impede electrochemical reactions which cause metals to corrode.

There are three classifications that define an inhibitor: reactive, precipitating, and filming inhibitors. Controlling Metal Ion Fouling in Industrial Water Systems by Zahid Amjad, Ph.D. based deposits typically encountered in cooling water systems contain MnO 2.

Fe 2+ The levels and/or types of these corrosion inhibitors. Biological Fouling Inhibitors. Recommend dosing cooling towers with two biocides (oxidizing & non-oxidizing) with an automated dosing system proportional to the system volume to inhibit biological fouling.

FOULING CHARACTERISTICS OF COOLING TOWER WATER CONTAINING CORROSION INHIBITORS I. INTRODUCTION The term "fouling" is used to mean any deposit on heat transfer surfaces which increases the resistance to heat transfer. Cooling tower water. In Cooling tower as water evaporates alkalinity increases and ph goes upto to • pH is so adjusted by dosing H2SO4 that the Langelier Saturation index of the cooling water is always.

Within Cooling Towers, the forces of corrosion, abrasion, and erosion can have devastating effects. Changes in cooling Tower design and water treatment practices are, in some cases, elevating the exposure. The use of protective materials is becoming increasingly critical to extending the life of cooling tower .Title: Cooling Water Zinc Phosphonate Corrosion Inhibitors - Cooling Tower Scale Inhibitors Author: Monodeep Mukherjee Subject: The antiscalants are required to inhibit scale formation inside Cooling Towers, Air Washers, Evaporative Condensers, Cooling Water Heat Exchangers, Radiators, Gear Boxes, Injection Moulding Machines, Blow Moulding Machines, Housings, and etc.
