Seeking information on the corrosion effects of centrifugal pumps on sludge in water treatment plant sedimentation tanks (containing the coagulant polyaluminum chloride)
Thread Content
Inquire about the corrosion effect of the sludge from the sedimentation tank of the water treatment plant (containing 0.2% polyaluminum chloride as a coagulant) on the sludge transfer pump. What is the corrosive impact of sludge containing polyaluminum chloride on lift pumps, and should this impact be taken seriously?
The media involved in wastewater treatment are complex, so the selection of equipment required necessitates predictive design. There are many anti-corrosion pumps available on the market nowadays; it’s just a matter of choosing one that suits your needs. Focusing only on attention without taking action leads to damage.
Inside the PAC, there is some free HCl present; a high concentration of chloride ions causes significant corrosion to the pipelines and pumps.
