Melspring International

What Melspring International does

Melspring International B.V. is a Netherlands-headquartered specialty water treatment chemicals company founded in 1958 and operating as a subsidiary of Blue Solutions alongside sister company Interhiva. The company formulates, develops, and distributes water treatment chemicals across six verticals: Pool Care (residential and professional), Wastewater Treatment, Sludge Treatment and Manure Processing, Drinking Water Preparation, Greenhouse Horticulture (discontinued), and Maritime applications. Its core technology centers on disinfection chemistries — most notably the Melclorite calcium hypochlorite product family (granular and tablet variants with 70% active chlorine content) sourced via exclusive distribution partnership with Nippon Soda — alongside flocculants, coagulants (iron and aluminium salts), pH correctors, H2S/odour control agents, and specialty cleaning products. The company holds certifications across Kiwa Water Mark, ISO 9001, ISO 14001, NSF, AWWA, EPA, DIN, and ECHA Article 95 (Biocidal Products Regulation).

Melspring operates four production facilities across the Netherlands (Velp headquarters), France, Spain, and the Czech Republic, distributing products to water boards, municipal and industrial wastewater treatment plants, pool and spa distributors, and private pool owners across Europe, Russia, the Middle East, Africa, and the Caribbean. Revenue is generated through direct sales to enterprise and government customers, a multi-tier distributor network, exclusive distribution of third-party manufactured chemicals (Nippon Soda, Nissan Chemicals), and differentiated sub-brand channels — Pool Power for online retail of consumer pool chemicals and Melpool for professional dealer distribution. The company also provides laboratory testing, field trials, and technical advisory services as a complement to its chemical product sales. A strategic reorientation recently discontinued greenhouse horticulture water treatment to refocus entirely on (waste)water operations.
