Wastewater Technology Fact Sheet: Ammonia Stripping
Wastewater Technology Fact Sheet: Ammonia Stripping

Ammonia stripping works well with wastewater that has ammonia contents between 10 to 100mg/l. For higher ammonia content (more than 100mg/l), it may be more economical to use alternate ammonia removal techniques, such as steam stripping or biological methods. Air stripping may also be used to remove many hydrophobic organic

How to Remove Lead from Your Industrial Water and Wastewater

There are several separation and treatment technologies that are commonly used to ,remove, lead from industrial water and ,wastewater,. Each treatment strategy offers certain advantages or fitness for particular applications; therefore, the best lead removal technology is one that fits a …

How Do You Remove Silica from Industrial Water and Wastewater?
How Do You Remove Silica from Industrial Water and Wastewater?

There are a few types of IX, and the type used for silica removal is strong base anion (SBA) resin operated in the hydroxide cycle, as silica is a weak ,acid,. When using IX to treat complex streams that contain silica as well as other contaminants, such as heavy metals, care must be taken to properly separate and/or dispose of any hazardous materials that may also exist in the stream.

The solution for sulphuric acid in wastewater | Almeco

The ,wastewater, must meet certain standards. To ,remove, the sulphides from the water, you could add a dose of FeCl3 directly into the reactor. By adding iron chloride, the hydrogen sulphide is converted to a slightly soluble iron sulphide with formation of hydrochloric ,acid, (HCl).

Removing Heavy Metals From Wastewater
Removing Heavy Metals From Wastewater

removed from the wastewater, typically by subsequent sedimentation and filtration processes, as explained in the next section. The metal solubilities presented in the previous figures are based on an ideal wastewater. Some variations in the exact values of the metal concentrations will occur due to the presence of other substances in the wastewater.

Therefore, by combining oxalic ,acid, and FA, Cr(VI) can be removed from ,wastewater, and its environmental toxicity can be reduced simultaneously. In this study, we investigated a two-step method to eliminate Cr( VI ) from ,wastewater,; in detail, the first step included the reduction of Cr( VI ) to Cr( III ) in the presence of oxalic ,acid,, followed by the adsorption of Cr( III ) onto MFA.
