*3.4.2 Main economic benefits of VoxFlot*

VoxFlot flotation system has significant economic benefits compared to the present systems as follows:


### **4. Conclusions**

Water itself is a clean element and present everywhere in the natural processes and ecosystems. It is heavily loaded in process and wastewaters as well as in the nature on earth and ecosystems. The water can purify itself or leave its load by evaporation powered by sun energy. Water circulation can be said as the largest transportation system globally.

The VoxSton system removes many ways the entire or partial load of various water matrices and treats the water for recycling and discharge to nature. It is an integrated water clarification system that separates soluble ingredients, activates molecules, generates flotation bubbles evenly in the water flow, presses solids for recycling and treats the water for recycling and discharging to nature.

The VoxSton industrial process and wastewater treatment system is efficient and it can in the most cases treat the liquid from the process to finish continuously or daily basis. It can be installed directly into the liquid flow without equalization and precipitation.

The VoxSton or its parts can be applied in purification of various water matrices. It has been applied in water intake, industrial processes, various wastewater purifications, fish farms, refreshing of natural waters and pretreatment at water plants. The most challenging cases have been removal of pharmaceutical residues from city wastewater and radon from intake of ground water at water plants, and disinfection of a hospital wastewater.

The new process water treatment system VoxSton is an integrated and fast. It saves in energy, chemicals and space as well as in operational costs roughly by 50 percent compared to present advanced systems. The capital costs are estimated to be lower too.

The main benefits of the VoxSton compared to present industrial water treatment systems are presented in **Table 1**.

#### **Note**

VoxSton concept for process waters of P&P Industries has been published first time in 2016 in China [8, 9]. The basic concept remains the same but its subsystems of OxTube and VoxFlot are developed further applicable for many other water matrices.
