Our systems are DESIGNED TO TREAT:
Industrial wastewater from the food processing, brewing, beverage, dairy, and meat processing industries
Industrial wastewater from the petrochemical, pharmaceutical, and recycling industries handling various waste streams
Landfill leachate and process wastewater generated during biological waste treatment
Wastewater from tourist resorts, hotels, and campgrounds
Agricultural wastewater, including systems with energy recovery potential
Municipal wastewater from smaller communities and decentralized treatment systems
PLANT ENGINEERING & INSTALLATION
We design state-of-the-art standard and industrial wastewater treatment plants (WWTPs), including landfill leachate treatment systems, that meet the highest technological and environmental standards.
We focus on modular solutions that allow fast delivery and installation for industrial facilities, landfills, decentralized systems, and smaller municipalities.
Our projects are developed on a turnkey basis, covering every stage of implementation – from initial analysis and conceptual design to engineering, construction, commissioning, and long-term operational support.
RATIONAL ENERGY AND CHEMICAL CONSUMPTION
We design our treatment plants to ensure long-term operational stability, high reliability, and low operating costs. We place special emphasis on rational energy and chemical consumption, minimizing operator intervention, and maximizing process automation.
Depending on influent characteristics and effluent requirements, we apply advanced biological, physicochemical, and hybrid treatment technologies that ensure stable operation even under highly variable loads.
WASTEWATER AND LEACHATE TREATMENT SYSTEMS
At Croteh, we provide end-to-end industrial wastewater and leachate treatment solutions – from engineering and installation to regular service and maintenance – with a strong focus on energy efficiency, operational flexibility, and full environmental compliance.
Our modular and flexible treatment systems allow reliable management of wastewater streams in industrial operations, municipal infrastructure, and waste management facilities.
Through continuous plant monitoring by our accredited laboratory and 24/7/365 service support, our reliable team helps clients reduce operating costs and maintain continuous compliance with environmental regulations.

We develop technologies designed to:
- Reduce environmental impact through energy-efficient operation and lower carbon emissions
- Improve resource recovery, including treated water reuse and reduced sludge generation
- Simplify maintenance through specialized service programs for industrial and municipal treatment SMEs
By continuously monitoring plant performance, analyzing management system data, and performing laboratory testing in our accredited laboratory, we optimize treatment efficiency, reduce operating costs, and extend equipment lifespan.
We are also the only company in Croatia that provides continuous technological support and process optimization backed by in-house laboratory testing.
We offer long-term maintenance agreements that include scheduled technical inspections, laboratory analysis, optimization of operational parameters, regulatory compliance support, and reporting assistance.
When production processes change, wastewater loads increase, or regulations become more stringent, we upgrade and modernize existing treatment systems to maintain regulatory compliance – without requiring a completely new plant.
