Water Treatment Units

To avoid expensive and time-consuming investments, we offer containerized units for different wastewater treatment processes (screening, chemical dosing, flotation, etc). Each unit is engineered for a specific process, ready to plug and play. The units can be combined into a tailored wastewater treatment solution. The system comes with full process automation required for reliable and safe operation. Integrated online monitoring keeps you up-to-date about process operation at any time and any place.

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. Roxia also develops completely new technologies for water treatment. As our water treatment flag ship, check out the world’s first direct plasma oxidation system: Roxia Plasma Oxidizer


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

Circular Economy: Reuse Waters

Circular Economy: Reuse Waters

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