How Can Roxia Solve Your Problems?

We have a systematic and customer-oriented approach to find the best water and wastewater treatment solutions.

Preliminary assessment

We help define the basic information and collect all technical details. Then we assess the scope of the challenge and conceptualize probable solutions. Through site visits and field testing or laboratory studies, we gain understanding of the onsite opportunities and how the water responds to treatment.

Solution proposal

After the preliminary assessments, Roxia experts may offer pilot studies, design on flow chart level and estimates on the scope of the likely investment and related operational expenses. Pilot-scale studies of the wastewater are done with a variety of technologies and processes.

Design, delivery & support

After reviewing all information, we conduct a detailed design project for the water treatment system, manufacture and deliver the process. Roxia offers continuous support to ensure our customers meet and maintain their target emission levels!
