Wastewater analysis
Thread Content
What are the common analysis items for wastewater?
pH, COD, ammonia nitrogen, suspended solids, colority, phosphate, nitrate, nitrite, 30-minute sedimentation ratio, sludge concentration, sludge index.
Routine analysis includes suspended solids, COD, BOD5, color, ammonia nitrogen, total phosphorus, etc
Ordinary companies only test COD, ammonia nitrogen, and color intensity; for environmental inspections here, an online analyzer was installed, but it is used only to analyze COD.
pH and COD are the most important! It’s definitely essential!
I recommend checking out \"Methods for the Monitoring and Analysis of Water and Wastewater (4th Edition)\\"; it’s a good book, and it’s available for download everywhere. :handshake
Online analyzers for COD, BOD, ammonia nitrogen, nitrate nitrogen, nitrite nitrogen, oil, sulfur, cyanide, pH, and suspended solids basically only analyze COD
The pH range of wastewater, suspended solids concentration, chemical oxygen demand concentration, ammonia nitrogen concentration, petroleum content, animal and vegetable oil concentration, and phosphate levels. The analysis lab mainly measures COD.
COD, chloride ions, pH, mercury testing
BOD should also be essential, right?
PH, COD, ammonia nitrogen, suspended solids, nitrate nitrogen, nitrite nitrogen, sulfur, BOD, etc
Ammonia nitrogen, pH value, COD, CI ions
Dissolved oxygen is also important. But now there are online dissolved oxygen meters.
Our factory conducts some routine analyses, such as pH, colority, suspended solids, COD, ammonia nitrogen, phosphate, and chloride ions; in addition, we also determine the average bacterial count.
COD, PH, SS, free chlorine, ammonia nitrogen, total nitrogen, total phosphorus, colority, petroleum compounds, phenols, heavy metals, etc
The last edit to this post was made by Canghai Yili Sha on 2009-6-26 at 15:25. PH, COD, and color intensity must definitely be measured; generally, enterprises target certain specific values, and then specialized wastewater treatment companies collect the wastewater for centralized treatment.
It depends on the specific conditions of your wastewater; for the impurities mentioned in some projects, if they are not involved at all in the production process, it is possible to stop testing them after conducting a few measurements.
Our wastewater analysis includes: pH, COD, TOC, ammonia nitrogen, volatile phenols, total phosphorus, total nitrogen, SS, color, and organic characteristic pollutants
pH, total alkalinity, total hardness, suspended solids, turbidity, chlorides, CODcr, ammonia nitrogen, calcium ions, magnesium ions, sulfate ions, and so on. For some wastewater that needs to be desalinated and reused, it is also necessary to monitor the salt content (or conductivity) in the water
Hehe, environmental protection requirements vary across different industries. I think things like pH, suspended solids, and COD are definitely the essential criteria
