Wastewater Treatment

Flowrox Environmental Technologies offer flexible solutions for industrial wastewater treatment. Together with our partner network, we have access to state-of-the-art technologies and vast expertise in water and wastewater processes. Our approach starts with a careful study and investigation of onsite options, laboratory and pilot-scale tests and finally full-scale process design and complete solution delivery. Not only do we provide new solutions but we also offer services to improve existing ones. We also offer continuous support for our customers to meet and maintain their target emission levels.

Processes & Technologies

Water treatment nearly always requires a multi-step process combining several unit operations. We apply the best available techniques and find the most feasible combination to each case. Such techniques typically include chemical treatment like pH control, coagulation and flocculation; flotation, settling or other solid-liquid separation processes like filtration; aeration or advanced oxidation etc. Flowrox also develops completely new technologies for water treatment. As our water treatment flag ship, check out the world’s first direct plasma oxidation system: Flowrox Plasma Oxidizer.

Wastewater treatment for industries:

  • Mining, Minerals processing & Metallurgy
  • Steel & Metal
  • Pulp & Paper
  • Fish & Meat
  • Chemical
  • Energy
  • Textile
  • Other manufacturing industries


Studies of the wastewater are done by Flowrox experts with a variety of technologies and processes.

How Can Flowrox Solve Your Problems?

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

1. 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.

2. Solution proposal

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

3. Design, delivery & support

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

Circular Economy: Reuse Wastewater

Once treated appropriately, industrial wastewaters can be reused onsite. Such opportunities are easily overlooked and require careful learning of the plant operation and the processes where water is used. Flowrox experts can review these opportunities and help customers reduce the amount of spent and discharged waters.



We assess the scope of the challenge and conceptualize probable solutions.

Flowrox GeoBox is designed as an inexpensive solution for applications where sludge volumes are not huge but cause unnecessarily high costs.

In this process, Flowrox GeoBoxes are dewatering oily and sandy sludges. The former are then transported to the biogas production and the latter for composting.
