BDD vs Lead Dioxide Electrode On Color And COD Removal Efficiency

Pollutant molecules must be adsorbed onto the PbO2 surface to able to be oxidized while unique SP3/SP2 strture, semiconductor nature of BDD electrode make the surrounding area a location where highly intensive oxidation happens, PbO2 electrode is oftenly fouling if there are substances impact the lead surface, which make COD removal with the lead dioxide electrode a restrained, linear redox process, bdd can make the COD reach undetectable level, while lead dioxide electrodes are limited.

Organic pollutants mineralization COD degradation rate of BDD anode reaches some 92%, yet save 30-55% of the time with PbO2 anode when it comes to complex industrial waste streams, as the whole surrounding area of the “non-active” BDD anode is a highly intensive oxidation zone.                                                                                                                                                                    Our electrode material engineers conducted a side-by-side comparison of BDD anode and lead dioxide electrode, recorded a 50% higher on color removal, 25% on higher on COD degradation rate, then some 45% lower on actual electric energy consumptions. *actual data might defer under different conditions.

a comparison of bdd electrode vs platinum electrode

BDD vs Platinum Electrode In Real Wastewater Treatment, Out of the lab

Platinum has a relatively low oxygen evolution overpotential (OEP) at some 1.6V, which means a certain part of energy is consumed with water splitting, while “active” nature of Pt make the oxidants, e.g, hydroxyl radicals adsorbed strongly to the Pt surface to form PtO, make the redox process selective, competing with the oxidation of organic compounds and reducing current efficiency. therefore Platinum is effective for scenarios when it require simple disinfection or partial COD removal, organic pollutants can be easily oxidized.

With the widest electrochemical window, OEP over 2.3V, non-active BDD electrode has very weak adsorption of oxidants e.g. hydroxyl radicals, meanwhile spend most of the energy on the oxidant generation instead of side reactions like water splitting, non-selective breaking down organic pollutants into intermediates, then further oxidation into CO2 and water.

This engineering team recorded BDD electrodes have some 30% to 50% higher than platinum electrode with TOC removal rate under the same current density and redox time, all the data and information are collected during our testing.

BDD electrode vs DSA electrode

BDD Electrode Vs. DSA Electrode In Real Wastewater Treatment Applications

With oxidation potential at 1.6V to 1.8V, DSA electrode usually consist of titanium substrate with mixed metal oxides coating such as IrO2, RuO2. Hydroxyl radicals and other oxidants are adsorbed to the surface to enable selective oxidation of those organic compounds with simpler structures, ammonias, or pathogens, makes DSA electrode cost effective for large scale municipal application with a high flow, low complexity.

With an oxidation potential at 2.3V to 2.7V, BDD electrode can break down refractory organic pollutants with complex bonds /structures, e.g, PFAS, phonels, aromatic hydrocarbons, “Non-active” BDD electrode has weak affinity for hydroxyl radicals, which means oxidants remain highly reactive near the surface. 

This results in highly efficient treatment of complex industrial effluents e.g. pesticides, petrochemicals, chemical production, pharmaceutical, landfill leachate, and those waste streams resists conventional biological or physical-chemical treatments

Application of BDD Electrode In Electro Oxidation Wastewater Treatment

application of bdd electrode in electro oxidation wastewater treatment processes

From a wastewater treatment perspective, this unmatched hydroxyl radicals generation capability makes BDD electrodes particularly suitable for practical treatment of complex industrial wastewater, espeically waste streams with a high concentration level of persistent organic pollutants, high salinity, or high COD, these wastewaters are refractory to conventional biological and physicochemical treatment methods.

Therefore deep oxidation and byproduct mitigating are critical elements for performance evaluations, that is where BDD electrode step in with a true non-selective electro oxidation process thanks to hydroxyl radicals produced in bulk, as •OH radicals indiscriminate wider range of organic compounds, breaking them down through consecutive oxidation steps to realize full mineralization to CO₂ and H₂O. 

What is more, BDD anode does not promote the formation of surface-bound oxidants or active chlorine species unless high halide concentrations are present, which slash the risk of persistent or toxic byproducts formation.
