What Dialynas does
Dialynas S.A. is a Greek environmental technology company headquartered in Heraklion, Crete, specializing in decentralized wastewater treatment, water reuse, and food waste management for public-sector clients in Greece and Cyprus. The company's core technology stack is built around attached-growth biofilm textile-filter systems — AdvanTex AX-100, AX-MAX 250-35, AX-20, AX-10 — and EKOL compact units, supplemented by autonomous mechanical composting units (AMK/ACU, and SMEC units sourced from INCOTECH) for food waste diversion. Its Neapoli plant is claimed to be the largest wastewater treatment plant in Europe using textile filter technology. The portfolio is reinforced by an in-house ESYD-accredited testing laboratory (ISO 17025, No. 985) performing physicochemical and microbiological analysis, an e-learning platform for plant operators, and energy-self-sufficient designs such as the Sourias solar-PV-equipped facility.
The business operates exclusively through business-to-government (B2G) public procurement, winning competitive tenders from Greek municipalities, municipal water utilities (DEYA), regional authorities, public development organizations (e.g., OAK S.A.), and the Cyprus Water Development Department. Revenue is generated primarily via Design-Build-Operate (DBO) contracts bundling design, construction, and 10-year operation and maintenance, plus discrete equipment supply, environmental consulting studies, and laboratory testing services. Contract sizes range from small O&M agreements (~€74,000) to multi-million-euro DBO concessions (€4.4M Neapoli, €5.95M Chios), with tertiary treatment for agricultural irrigation reuse as a recurring differentiator. The company participates in multiple EU-funded research consortia (A2UFood, Holistic, AQUASYN) as both a technology provider and visibility mechanism, and is investing in a new 2,750 sq.m. owned production and laboratory facility announced October 2024 to scale manufacturing and accredited testing capacity.

Dialynas competitors and assessment
Company assessmentBroad incumbents
- WABAG Group: WABAG is a Vienna-based international plant engineering company specializing in municipal and industrial water/wastewater treatment design, construction, and operation - including DBO contracts in Southeastern Europe and Mediterranean markets that overlap with Dialynas's geography.
- SUEZ Water Technologies & Solutions: SUEZ operates a global water and wastewater treatment business with municipal and industrial solutions, including decentralized systems. As a broad incumbent, SUEZ competes with Dialynas on larger Greek and Cypriot municipal tenders and represents the scale competitor in the same space.
- Veolia Water Technologies (Veolia Environnement): Veolia Water Technologies is a global broad-line water and wastewater treatment equipment and services provider serving municipal and industrial customers. While much larger and broader than Dialynas, Veolia competes for major Greek municipal tenders and provides the broader incumbent benchmark for decentralized WWTP capabilities.
- Nijhuis Water Technology (Nijhuis Industries): Nijhuis Industries provides industrial and municipal wastewater treatment solutions, including biological treatment systems and DBO contracts in Europe. They operate as a comparable European mid-sized environmental services firm bidding on similar municipal and EU-funded tenders.
Direct peers
- Hydrotech / Hydro Group: Hydro Group manufactures and supplies water filtration, treatment, and biological systems including AdvanTex-style textile filter media for small community and municipal applications. Their product technology and customer base closely parallels Dialynas's technology sourcing and system deployment focus.
- Smith & Loveless: Smith & Loveless designs, manufactures, and operates packaged wastewater treatment plants for municipalities and industrial applications, often via design-build-operate models. Their DBO + packaged plant approach mirrors Dialynas's Greek municipal business model.
- BioMicrobics: BioMicrobics specializes in decentralized and commercial wastewater treatment systems, serving small communities, resorts, and municipal applications in markets where centralized sewer systems are impractical - closely analogous to Dialynas's island and small-settlement focus in Greece and Cyprus.
- Premier Tech Water and Environment: Premier Tech offers decentralized wastewater treatment, composting, and water reuse solutions including Ecoflo biofilter systems and composting units. Their decentralized biological treatment and food-waste composting portfolio closely overlaps with Dialynas's AdvanTex + AMK product set.
- Orenco Systems: Orenco Systems is a US-based manufacturer of decentralized wastewater treatment systems using advanced AdvanTex attached-growth textile filter technology - the same core platform Dialynas deploys. Both companies serve small municipalities and decentralized communities with packaged biological treatment plants.
Regional players
- Cyclus Enviro (municipal environmental services in Greece): Regional Greek environmental services firms compete with Dialynas on island and small municipality tenders, providing alternative DBO, equipment supply, and O&M services within Greece's domestic wastewater market.
