“…However, it is possible to distinguish a number of electrochemical SPE-based devices, which may find their own market niches. In particular, among such devices are the oxygen concentrator [ 3 , 4 ], the hydrogen concentrator [ 5 ], the air dryer [ 6 ], the ozone generator [ 7 , 8 ], and the converter of alcohols (methanol, ethanol, etc.) [ 9 , 10 ].…”

This research reviews nano zero valent metal oxidation coupled with ozone for degradation of wastewater effluent. The technology in wastewater treatment is gradually innovating. Car wash wastewater constitutes and promotes water and environmental pollution. In wastewater treatment, a variety of methods are available for treatment of wastewater. The chosen method should be cost effective and easy to operate. In the treatment of car wash wastewater, certain parameters are investigated such as pH, time, dosage of treating agent, presence of hydrogen peroxide, and competing cations. The characteristics of treated and untreated car wash wastewater are usually analysed, produced catalyst morphology and elements maybe observed and compared using the XRD, FTIR, SEM + EDx, and BET. A combined treatment of different phases is reported to remove total suspended solid (TSS), inorganic materials such as sodium chlorides (NACL), heavy metals such as lead, oil and grease, as well as phosphates and nitrates. This review will discuss on the treatment methods being practised in wastewater engineering field, chosen treatment methods after review with supports, and combination concerns on the chosen treatment methods along with consequences to the environment and human health.

The present study conducted an investigation on the effect of Superconducting-High Gradient Magnetic Field (S-HGMF) in the association solubilization of recirculating cooling water and the crystal form change of scale. The effects of magnetic flux density, flow rate and cycle-index on the solubility of scale-forming ions were investigated, and the effects of viscosity and surface tension on the molecular internal energy and order degree of circulating water were analyzed. The scale was ground and mixed with water and placed in a S-HGMF system to study the effect of S-HGMF on the crystal form change of CaCO3. The experimental results showed us that S-HGMF could increase the solubility of scale-forming ions. It could enhance the interaction between water molecules by increasing viscosity and reducing surface tension, so as to improve the stability of water quality, reduce ion precipitation, and achieve the effect of scale inhibition. At the same time, it could also change the crystal structure of CaCO3, promote the transformation of calcite to aragonite, and realize the purpose of scale inhibition. In a word, S-HGMF treatment can effectively solve the scaling problem of recirculating cooling water system, which provides a reference for scale inhibition of recirculating cooling water.
