Recovering fluoride from wastewater has large economic and environmental significance within the fluorine industry. A novel crystallization process was proposed for the recovery and the removal of fluorine-containing industrial wastewater by steps. A pilot-scale reaction-separation integrated reactor was used to recover the sandy …

Quartz deposits are widely dispersed in nature, but the presence of ore bodies capable of yielding high-purity quartz is exceedingly rare. As a result, the effective purification and processing of high-purity quartz from natural siliceous materials has emerged as a prominent area of research within the non-metallic mineral processing …

Owing to current global water scarcity, there is an urgent need for advanced water treatment technologies to be invested in wastewater treatment processes. Additionally, there is growing concern that some anthropogenic contaminants have been detected in finished drinking water and wastewater slated for reuse, such as organic …

In addition, other aeration and filtration technologies are also commonly used in this stage. Here, wastewater is passed through a filter medium to separate solids. Approximately 25–50% of the incoming BOD, 50–70% of the total suspended solids (SS), and 65% of the oil and grease are removed during primary treatment.
