The company supports its partners by designing, constructing, expanding, and renovating municipal and industrial drinking water treatment, wastewater treatment, and sludge treatment plants. Its scope of activities covers everything from design and permitting to turnkey implementation, and it also provides long-term operational services for industrial wastewater and water treatment systems. Its Serbian subsidiary, Veolia Water Solutions & Technologies Belgrade doo., acts as a general contractor for companies investing in Serbia.


Wastewater Treatment and Recycling

VWS has extensive experience in the application of specialized technologies used in wastewater treatment and recycling (MBR, MBBR, physico-chemical treatment, anaerobic and aerobic treatment, ultrafiltration, reverse osmosis, electrodialysis, evaporation, ozonation, etc.). Many technological elements are produced in the European manufacturing plants of the parent company, Veolia Environnement. Thanks to the development centres of the parent company and the European and overseas subsidiaries providing technological solutions, the full range of currently known municipal wastewater treatment processes is available. Depending on the needs and the problem to be solved, VWS offers wastewater treatment and recycling systems from compact units to traditional biological activated sludge or even complex solutions combined with membrane technology. Their processes include internationally recognized methods from primary to tertiary treatment, such as ActifloTM, BiostyrTM, or ZEEWEED MBBR technologiesTM. As supplementary services to municipal wastewater treatment, special attention is given to procedures aimed at handling and utilizing excess sludge generated during treatment, as well as eliminating odours arising during treatment processes.

VWS előmechanika

VWS has two decades of experience in industrial wastewater treatment. Its staff have implemented and commissioned numerous industrial wastewater treatment systems. The company’s technological background provides tried and tested procedures that have been successfully applied in all industrial segments (chemical industry, machinery manufacturing, energy, automotive, metal production, pharmaceuticals, electronics, mining, etc.). Most of the technological solutions and equipment used by VWS are manufactured by the parent company, while some unique processes and technological elements are provided by specialized partners in the respective fields. All technological processes are implemented according to the highest quality standards. Standard solutions can be delivered and commissioned within a short turnaround time. Several of these consist of modular elements, making them easily integrable into existing systems.


Industrial Water Treatment

In addition to wastewater treatment, VWS is also a leader in the comprehensive design and implementation of water treatment systems used in industrial processes. Through its water and wastewater services for various sectors, it has gained significant references and vast experience in implementing and operating water treatment technologies associated with industrial processes, from laboratory-scale systems to large-volume design and construction projects. With its available know-how and professional background, the company provides reliable and efficient solutions for domestic and international partners to address water-related issues arising in various technological and manufacturing processes, regardless of industry. Many technological elements (ultrafiltration, reverse osmosis, electrodialysis, UV, ozone disinfection, etc.) are manufactured in Veolia Environnement’s production plants in compliance with the highest European standards.

VWS specialists, after familiarizing themselves with the given technology or production process, define the parameters according to quality requirements, depending on whether water is involved as a component or as a medium in a chemical reaction or operation. To determine the quality requirements for industrial water, they assess the intended use and circumstances of the water, as well as the type and technical parameters of the water-using equipment. Based on the parameters defined for the intended use and the required water quantity, they provide comprehensive permitting, design, and construction project management services after developing the appropriate technological process.


Operation Services

VWS provides comprehensive operation services for players in both industry and the municipal sector. The company’s strength lies in its decades of experience not only in building wastewater treatment systems but also in their efficient operation, offering long-term operational schemes combined with financing. The company provides outsourced wastewater treatment and process water management services for its partners, during which, as a specialized environmental service provider, it assumes legal responsibility for full compliance with environmental regulations while operating constructed or taken-over treatment systems. The company’s specialized expertise and efficient operating organization result in cost savings for the client.

Contaminated Soil and Groundwater Remediation

The company has effective technology and 20 years of expertise and experience in soil and groundwater remediation. Remediation works primarily involve the construction and multi-year operation of waste management, water, and wastewater treatment technologies designed for cleaning contaminated soil and groundwater. With its construction and operational experience, the company is particularly suited for solving these complex environmental protection tasks. The remediation process includes damage assessment (test drilling, mechanical soil analysis, mapping hydrogeological characteristics), planning (selecting the appropriate physical/chemical treatment and designing customized mechanical solutions based on samples and preliminary experimental results), implementation (using comprehensive, mobile treatment systems including heavy machinery, laboratory, mobile office, and wastewater treatment equipment), and post-project monitoring (establishing a monitoring system for ongoing assessment of intervention effectiveness).
