Methods of chromium and heavy metals removal from wastewater
Methods of chromium and heavy metals removal from wastewater

Ion exchange can be used for purification of wastewater with salt content of up to 2.3 g / dm3 and small amounts of metals and acids. The process is also complicated and the reuse of the concentrated solutions after regeneration is impossible too.

(,Acid,) mine water drainage ((A)MD), characterised by neutral to low pH and high ,salt, and heavy metal ,content,, is recognized as one of the more serious environmental problems in the mining industry. (A)MD is produced when sulphide -bearing material is exposed to oxygen and water.

Separation and recovery of heavy metal ions and salt ions ...
Separation and recovery of heavy metal ions and salt ions ...

The desorption rates are ∼99.6% for Pb 2+ and ∼97.2% for Na +, which remain at ∼94.3% and ∼88.2%, respectively, without further degradation after 8 cycles. Overall, CDI with 3D graphene-based asymmetric electrodes is a promising route for the separation and recovery of heavy metals and ,salt, ions from ,wastewater,.

Reverse osmosis - Wikipedia
Reverse osmosis - Wikipedia

Reverse osmosis, (RO) is a water purification process that uses a partially permeable membrane to separate ions, unwanted molecules and larger particles from drinking water. In ,reverse osmosis,, an applied pressure is used to overcome osmotic pressure, a colligative property that is driven by chemical potential differences of the solvent, a thermodynamic parameter.
