RoadTrain® – Modular for Remote Locations
The Hydroflux Epco RoadTrain® is a modular wastewater treatment system designed for remote communities, mine sites, camps, and resorts. It offers a reliable, robust, and efficient solution for treating wastewater where traditional infrastructure is not feasible. The system can be pre-assembled for rapid deployment and factory-tested to minimise installation time and site requirements or supplied as a bolt-together design, similar to a flat-pack system, making it easily transportable and suitable for local site assembly.

Organica – Sustainable and Attractive STPs
New Zealand’s exclusive provider of Organica’s wastewater treatment solutions. Hydroflux Epco offers the Food-Chain-Reactor (FCR) system to various sectors, including large and small townships, as well as clients seeking an aesthetically pleasing sewage treatment plant design. The partnership between Hydroflux Epco and Organica ensures that New Zealand clients have access to sustainable, efficient, and visually appealing wastewater treatment options tailored to their specific needs.

Quality Membrane Bioreactors (MBR)
Hydroflux Epco delivers advanced Membrane Bioreactor (MBR) systems that combine biological treatment and membrane filtration in a compact, energy-efficient design. Whether you are upgrading your plant, retrofitting existing membranes or designing a new site, Hydroflux Epco can deliver with decades of experience working with a wide range of membrane technologies—including hollow fibre, flat sheet, nanofiltration, UF and RO. We offer innovative, turnkey solutions for municipal and industrial applications. Our MBR systems ensure high effluent quality, reduced sludge, and a smaller footprint—ideal for water reuse and sustainable plant performance.

Efficient Moving Bed Bioreactors (MBBR)
Advanced Moving Bed Biofilm Reactor (MBBR) solutions for biological wastewater treatment. These systems utilise specially designed biofilm carriers to promote high-rate microbial growth, ensuring efficient removal of organic matter and nutrients. MBBR technology is well-suited for municipal applications, whether for new plants or upgrading existing activated sludge systems, offering a compact, low-maintenance, and scalable treatment solution.

Surface Aeration
With a focus on energy efficiency and durability, Hydroflux Epco’s surface aeration systems are suitable for a wide range of applications, including activated sludge systems, lagoons, and oxidation ditches. These solutions ensure reliable performance, low operational costs, and effective wastewater treatment for modern facilities.
