WADIS - Model EPDA -Electrical Pulse Discharge Air System for Wastewater Disinfection
The EPDA system utilizes innovative technology that combines high-voltage and high frequency pulses discharge with an air bubble flow to treat and disinfect secondary or tertiary effluents, enabling their reuse. This process takes place in the secondary stage of wastewater treatment, where the water still contains some solid materials and has some turbidity, requiring additional purification for complete treatment and reuse. Typically, this is done by disinfecting the effluent with chlorine (which is prohibited), ultraviolet light, or ozone. EPDA system can replace these methods and obtain a greater quantity of better-quality water in an environmentally friendly manner, without the need to utilize chemical products or others.
The main advantages of this system are:
- It is not sensitive to the turbidity and opacity of wastewater, unlike UV rays.
- It achieves a high bacterial reduction in logarithmic terms (2 to 7 logarithmic scale units).
- It is highly effective against all types of microorganisms.
- It does not produce BDPs (disinfection by-products).
This system is especially useful for treating and disinfecting various industrial wastewater, which are a serious environmental problem. In addition, increasing pollution problems and the complexity of removing different contaminants from water, which hinders their treatment, coupled with the growing water demands and the increasing need to reuse water, require an improved treatment of wastewater.
WADIS water disinfection technology treats these waters and leaves them free of bacteria, viruses, fecal matter, pathogens in general, etc., resulting in excellent disinfected water for agricultural irrigation.
In summary, the EPDA system is an environmentally friendly and highly effective solution for the treatment and disinfection of wastewater, in municipal, industrial and others, for its reusing
*Additionally by adding another WADIS technological process (subsequent to this), it is possible to obtain drinking water.
Wadis` equipment came to change the rules of the game in a very traditional market that has not adapted to global requirements and lacks economical, simple, and effective solutions.
