Wet Air Oxidation (WAO) is a liquid phase reaction using dissolved oxygen in water to oxidize wastewater contaminants. The process converts organic contaminants to carbon dioxide, water, and biodegradable short-chain organic acids. Chemical Oxygen Demand (COD) is the measure of organic pollutants in the wastewater that need to be removed.
Since WAO is considered a green technology, federal environmental policy in China has been directing all chemical companies to upgrade its wastewater treatment systems to meet the new standard.
Pump Model: D03EKSGHFEHA
Flow: up to 1.8 gpm (6.8 l/min)
Discharge Pressure: up to 870 psi (60 bar)
Application: Solution containing solvents Acetone,
Ethanol & Acetonitrile
A conventional type of diaphragm metering pump is typically used to pump COD wastewater, but during the past five years, Hydra-Cell seal-less pumps have been supplanting the competitive technology. A major chemical company recently replaced its pumps with Hydra-Cell D35/G35 models because Hydra-Cell offers a compact design, low cost, less maintenance, and stable performance.
