Cooling towers form an integral part of many industrial facilities using some cooling tower water treatment system. Industrial companies at large need to keep the efficiency and productivity of cooling water systems at par, which calls for the use of water treatment chemicals. In general, the efficiency of industrial cooling water system is affected by various water source impurities causing undesirable deposition, scaling, and corrosion. If left untreated, these will result in critical system failures for heat exchanging equipment and eventually costly downtimes.
Biological impurities caused by organisms such as algae, fungi, bacteria, and protozoa, exploit the vulnerabilities in untreated chemical water equipment to thrive, leading to fouling and a variety of health and system issues. Plus, mineral scales and sludge inhibit the process of heat transfer crippling the overall process efficiencies. The presence of dissolved salts and minerals in circulating water is another key concern marring the efficiency of cooling water systems. To address these concerns, water treatment programs use a number of chemicals. Key chemicals used are chromates, polyphosphates, nitrites, zeolites, surfactants, orthophosphates, bio dispersants, PH regulators, and biocides.
Which factors drive the evolving demand for cooling water treatment chemicals?
In part, the adoption of some chemical treatment programs is driven by the need to ensure the optimum service life of the equipment and broadly by several environmental considerations to use freshwater responsibly. Stringent implementation of regulations pertaining to efficient wastewater management in industrial processes and various regional legislations on water treatment technologies are catalyzing the growth of the market. The market is primarily driven by the rising adoption of water treatment chemicals in a wide spectrum of industries, including power, food and beverages, mining and metallurgy, steel, oil and gas, and textiles and dyes.
The consistent focus on preventive maintenance measures by these industries for their water treatment towers provides a strong underpinning to the rising adoption. According to Transparency Market Research, the global market for cooling water treatment chemicals is projected to rise at a healthy pace over the assessment period of 2016–2024.
Which types of chemicals are likely to account for a substantial uptake?
A major part of process and efficiency losses caused to water cooling towers is caused by corrosion and scaling and hence scale inhibitors and corrosion inhibitors form a significant part of water treatment chemicals. Some of the key scale inhibitors and corrosion inhibitor chemicals used are dilute phosphoric acid, sodium tri polyphosphate, monoammonium and diammonium phosphates, monopotassium phosphate, ethylene diphosphonic acid, and includes numerous specialty chemicals. Together with biocides, these form a whopping share in the type of chemicals used in the global cooling water treatment chemicals market. The variety of biocides include bronopol, isothiazoline, calcium hypochlorite, stabilized bromine, and sodium bromide.
Advances in technologies and methods for water treatment in industries in the power sector is an exciting evolution favoring the demand for cooling water treatment chemicals. Hager + Elsässer GmbH, a manufacturer of industrial process water and wastewater treatment, announced in February 2018 that it has completed the delivery of demineralization water treatment plant for a power station in Mozambique, through its subsidiary. Companies in the power generation industry can leverage on the technology to meet various current and emerging wastewater treatment needs. In the cooling tower facilities, the solutions will be used in ultrafiltration and for various methods of precipitation.

Which regions account for bright outlook for the substantial uptake of cooling water treatment chemicals?
On a regional front, Europe, Asia Pacific, and the Middle East are potentially prominent markets for cooling water treatment chemicals. In particular, Asia Pacific countries such as Indonesia, India, China, and Thailand form the core of the demand and are expected to provide several lucrative prospects in the coming years. Meanwhile, Spain and Russia in Europe and the UAE in the Middle East are rising at a prominent pace over the assessment period, driven increasingly by regulatory thrust for the reduction of wastewater discharge from water cooling towers. In addition, the need for preserving the scarce freshwater availability for industrial processes has bolstered the uptake in these emerging markets.
