The demand for water treatment chemicals is increasing as municipal and industrial systems require treatment to produce safe, reusable water that meets operational needs and regulatory standards. The rising demand for advanced chemical treatment programs stems from organizations increased regulatory requirements to manage effluent discharge and water reuse processes, as well as their environmental sustainability efforts. End users now prefer multifunctional formulations that deliver high performance because these products can handle scale control, corrosion protection, biofouling prevention, and sludge reduction, which enables them to use fewer treatment solutions and achieve lower total operating expenses. Industrial water-intensive sectors such as power generation, oil & gas, chemicals, and manufacturing, as well as rapidly expanding data centers, drive ongoing demand for effective treatment chemicals.

"Corrosion inhibitors type is projected to have the third-largest market share by type, in terms of value, during the forecast period."

Corrosion inhibitors would hold the third-largest market by type, as they provide essential protection against asset damage while ensuring operational reliability in industrial and municipal water systems. The combination of aging water infrastructure and the use of metal-intensive equipment in boilers, cooling towers, heat exchangers, and pipelines has resulted in a significant increase in expenses for corrosion-related maintenance and for controlling corrosion failures. Industrial sectors, including power generation, oil & gas, chemical production, and manufacturing, need corrosion inhibitors to protect their equipment from damage, prevent system leaks and unplanned downtime, and support their energy consumption goals. The increasing use of closed-loop water systems together with high-cycle cooling operations and water reuse practices leads to greater corrosive ion concentration which increases the risk of corrosion and drives continuous demand for inhibitors.

"Boiler water treatment application accounted for the third-fastest-growing application, in terms of value, during the forecast period."

Boiler water treatment is the most significant and fastest-growing application market in water treatment chemicals, driven by increasing demand for efficient steam generation across industries such as power generation, oil & gas, chemicals, and food & beverage. To avoid scaling, corrosion, and furring, which may be extremely important to heat transfer effectiveness and equipment life, boiler systems must be carefully managed chemically. The heightened concern for energy efficiency and operational reliability has prompted the resort to use special chemicals, such as oxygen scavengers, corrosion inhibitors, and scale control agents. Also, the growth of industrial infrastructure, especially in Asia Pacific, is driving market growth, as the adoption of high-pressure boilers in the manufacturing industry and energy sector is on the rise.

"North America is expected to have the third-largest market in the water treatment chemicals market during the forecast period, in terms of value."

North America would hold the third-largest market share in the water treatment chemicals market primarily due to its highly developed water infrastructure, stringent environmental regulations, and strong industrial base. The region uses treatment chemicals in municipal and industrial systems because it has some of the world's strictest water quality and effluent discharge standards, which require continuous chemical usage for water treatment. The US and Canada water and wastewater infrastructure need higher chemical doses due to aging systems that require additional chemical treatment to maintain water quality, protect against corrosion, and extend equipment lifespan. North America also hosts a large concentration of water-intensive industries, including power generation, oil & gas, chemicals, food & beverages, pharmaceuticals, and rapidly expanding data centers, which consume high-value and specialty water treatment chemicals.

In der Thüringer Landtagsfraktion des Bündnis Sahra Wagenknecht (BSW) steht ein Führungswechsel an. Fraktionschef Frank Augsten hat überraschend seinen Rücktritt angekündigt. Der 67-Jährige, der den Vorsitz erst seit Dezember 2024 innehatte, will das Amt in den kommenden Wochen an eine Nachfolgerin oder einen Nachfolger übergeben und die laufenden Geschäfte bis dahin noch weiterführen. Wer die Fraktionsspitze künftig übernimmt, ist nach Angaben aus Fraktionskreisen bislang offen.

Augsten begründete seinen Schritt nach übereinstimmenden Berichten aus Partei- und Fraktionskreisen mit persönlichen Gründen und dem Wunsch, sich wieder stärker seiner fachlichen Arbeit in der Landwirtschafts- und Umweltpolitik zu widmen. "Im Landwirtschaftsbereich brennt gerade die Luft", sagte der Agrarwissenschaftler mit Blick auf Betriebe, die wegen eines Streits mit der EU mit hohen Rückforderungen konfrontiert sein sollen. Für das BSW sitzt er im Landwirtschafts- und im Umweltausschuss und fungiert als agrarpolitischer Sprecher der Fraktion.

Der frühere Grünen-Politiker hatte bereits eine längere politische Laufbahn hinter sich, bevor er 2024 zum BSW wechselte. Zwischen 2009 und 2014 saß Augsten für Bündnis 90/Die Grünen im Thüringer Landtag und war zeitweise Co-Vorsitzender der Landespartei. Zwischen seinen Mandatszeiten arbeitete der studierte Agraringenieur unter anderem als Referatsleiter im Thüringer Landwirtschaftsministerium und später als kommissarischer Präsident der Thüringer Landesanstalt für Landwirtschaft. Im BSW übernahm er den Fraktionsvorsitz, nachdem Katja Wolf im Zuge der Regierungsbildung Ministerin geworden war.

Die Personalie trifft eine Fraktion, die nach der Landtagswahl 2024 mit 15,8 Prozent der Stimmen aus dem Stand zur drittstärksten Kraft im Erfurter Parlament aufgestiegen war und bislang als vergleichsweise geschlossen galt. Das BSW ist Teil der sogenannten Brombeer-Koalition mit CDU und SPD. Das Bündnis unter Ministerpräsident Mario Voigt (CDU) verfügt mit 44 der 88 Sitze über keine eigene Mehrheit und ist deshalb immer wieder auf Unterstützung aus der Opposition von Linken und AfD angewiesen. Innerhalb der Koalition hatten zuletzt vor allem der Umgang mit AfD-Anträgen und die Frage, ob „inhaltlich gute Anträge“ der AfD in Fachausschüsse überwiesen werden sollen, für Spannungen gesorgt. Augsten hatte sich öffentlich für eine inhaltliche Prüfung solcher Vorlagen ausgesprochen, während insbesondere die SPD-Fraktion eine solche Linie ablehnt.
