The static mixer for the cavitation of water
ZPM stands for Zeta Potential Mixer and is a static mixer manufactured in stainless steel 1.4571. The cavitation reactions help to disinfect the water for a lifetime.
Upstream of the filter — optimize coagulation and flocculation:
The ZPM amplifies the coagulation and flocculation reactions for the conversion and precipitation of dissolved components into small particles. The cavitation reactions provide the perfect mixing and turbulent environment necessary for coagulation using APF and NoPhos. The ZPM neutralises the electrical charge (Zeta Potential) on dissolved chemicals and small particles to make some positively and some negatively charged. The opposite charges attract and this causes coagulation and flocculation. As the electrical potential drops to neutral, the redox oxidation potential of the water increases by up to 100 mV, effectively the water is beginning to disinfect itself without the use of any chemicals. Choose the size of the ZPM according to the pressure loss. Pressure loss should be between 1 and 2 mWS
(0,1 – 0,2 bar).
Downstream of the filter – mechanical disinfaction:
The cavitation produce nano-bubbles that disinfect the water. The higher the pressure loss, the better the disinfection performance. Some pathogens (e.g. Cryptosporidium) as well as biofilm Protected colonies of bacterium floc are extremely resistant to chlorine. The ZPM breaks these colonies or floc apart and allows chlorine to disinfect the water before it reaches the pool Choose the size of the ZPM according to the pressure loss. Pressure loss should be between 1 and 5 mWS (0,1 – 0,5 bar)
