Miridon OÜ

What Miridon OÜ does

Miridon OÜ is an Estonian private limited company founded in 1997 that specializes in the design, sale, installation, and maintenance of drinking and domestic water treatment equipment. The company operates from two offices in Estonia (Tartu headquarters and a Tallinn branch) and serves three distinct customer segments: residential consumers with well or municipal water quality issues, municipal authorities requiring water treatment plant infrastructure, and industrial enterprises needing process water, boiler water, and demineralized water systems.

The company's technology stack covers the principal water treatment modalities, including reverse osmosis (RO) membrane systems, ion exchange softening and demineralization, mechanical filtration (sand, Birm, Greensand, activated carbon), ultraviolet sterilization, ultrafiltration, electrodeionization (EDI) for ultra-pure water, and Veolia Hydrex chemical dosing programs. Miridon differentiates through an in-house accredited water testing laboratory (certificate L309, EVS-EN ISO/IEC 17025:2017) issued by the Estonian Accreditation Centre, and holds ISO 9001 and ISO 14001 certifications since 2012. The product portfolio also includes Hydraloop greywater recycling, PVC-U piping systems, dosing pumps, filter media, and consumables such as tablet salt.

Miridon's business model combines one-time equipment sales and project-based design/construction services with recurring maintenance contracts and consumable supply (salt, chemicals, filter media). Distribution is direct, sales-led, and consultation-heavy, requiring water analysis before equipment recommendation, supplemented by an official Grundfos maintenance partnership that provides authorized service for dosing pumps across Estonia. No pricing is publicly disclosed for equipment; only laboratory analysis packages carry published unit prices. The company is privately held with no institutional equity history beyond EU co-funding grants, and operates primarily within the Estonian domestic market.
