These wastes can be acidic or alkaline and contain significant concentrations of heavy metals. Acid plating solutions generally contain free acids and heavy metals such as copper, nickel, zinc, and possi- bly tin or cadmium. Alkaline plating solutions in- clude zinc baths and sometimes tin baths.

Anodizing - Wikipedia
Anodizing - Wikipedia

Anodizing, is an electrolytic passivation process used to increase the thickness of the natural oxide layer on the surface of metal parts. The process is called ,anodizing, because the part to be treated forms the anode electrode of an electrolytic cell. ,Anodizing, increases resistance to corrosion and wear, and provides better adhesion for paint primers and glues than bare metal does. Anodic films can also be …

The opposite condition took place in strongly ,acidic wastewater,. Alam et al. ( 2017 ) conducted electroflotation studies on effect of pH on bubbles size using Iridium dioxide-coated titanium anode, and SS 316 cathode and concluded that the neutral pH condition was in favour of smaller hydrogen bubbles whereas smaller oxygen bubbles were produced in ,acidic, solution.

Note 1. pH: A scale indicating whether substances are ,acidic or alkaline,. pH7 is neutral. pH values below 7 indicate increasing acidity, while values above 7 indicate increasing alkalinity. Note 2. COD (chemical oxygen demand): The amount of oxygen consumed to oxidize organic substances (pollution) in water.

Values below 7 mean that the solution is ,acidic, and higher values represent ,alkaline, solutions. The recommended PH value for a water-miscible fluid is between 8.8 and 9.2. When the PH value drops below 8.0, it means that the fluid is becoming less efficient and has a higher risk of both corrosion and microbial contamination.

Simple demulsification can be achieved by using a technique referred to as Acid-Cracking. By reducing the pH of the ,wastewater, to a range between 2 and 4, the free oil will separate and rise to the surface of the oil water separator. Ellis engineers have responded by designing the Emulsion Breaking System (EBS).
