Analysis
Jianghai Environmental was established in Changzhou in 1991 and provides water-treatment chemicals, solutions, and services. [1] Ecolab’s current company profile lists power, steel, chemical, and oil-and-gas applications among the markets served by the Jianghai and Nalco businesses. [1] The operating model includes water-management programs, treatment chemistry, technical service, and a stated five-step service approach. [1]
In June 2015, Ecolab acquired a controlling interest in Jianghai, whose operations were based in Changzhou. [2] At the time, Ecolab said Jianghai had more than 550 employees, two plants, and approximately $90 million in 2014 sales. [2] Ecolab’s subsequent regulatory filing classified the transaction as an acquisition of an industrial water-treatment company and reported an approximately $190 million purchase price. [3]
Ecolab presented the transaction as a way to expand its water business in China and complement Nalco’s existing capabilities. [2] The company said it would serve Chinese customers through both Jianghai and Nalco brands. [2] Jianghai’s current profile continues to identify the company as an Ecolab subsidiary and describes a combined domestic and overseas footprint. [1]
Ecolab’s 2015 annual report said the acquisition increased the size of its total water business in China by approximately 50%. [4] The current Jianghai profile still identifies two plants and more than 550 employees, although those figures are not presented there as a newly audited current count. [1] The public record supports an active Ecolab-controlled water-treatment operation with continuing Jianghai and Nalco branding, but it does not disclose a standalone current revenue figure for the partnership.

Ecolab’s corporate history traces to 1923, when it operated as Economics Laboratory with one employee, one market, and one product: Absorbit carpet cleaner for hotels. A company sustainability report says that the business added Soilax detergent for automatic dishwashers in 1924, an early example of the combination of chemistry, dispensing equipment, and service that later defined Ecolab’s operating model. [1]
Ecolab now describes itself as a global provider of water, hygiene, and infection-prevention solutions and services. Its current company profile says that approximately 48,000 associates support millions of customers in more than 170 countries, including more than 25,000 sales-and-service associates, 1,100 scientists, engineers, and technical specialists, and 1,200 digital experts.

Ecolab identifies it as a subsidiary within its water business and describes its customers as including power plants, iron and steel producers, chemical manufacturers, and oil exploration and production companies.

Ecolab announced in June 2015 that it had acquired a controlling interest in Jianghai, which it described at the time as headquartered in Changzhou, with 2014 sales of approximately $90 million.
