Removal of Cu(II) from wastewater by waste tire rubber ash
The influence of pH, adsorbent dose, initial Cu(II) concentration and contact time on the removal of Cu(II) from aqueous solution by the batch adsorption technique using waste tire rubber ash as a
Firstly, a Cu-TREB was used to remove Cu(II) from wastewater, and the maximum power density of 37 W m −2-electrode was obtained with an energy density of 280 W h m −3 and a removal efficiency of 63% during the treatment of 0.1 M Cu(II)-laden wastewater .
Treatment of low-level Cu(II) wastewater and regeneration
Based on the CDI-EDI stack, the simulated Cu(II) wastewater (C0 = 42.9 mg/L) was treated, and its average removal rate in 1st cycle cathode- and anode-effluent was 95.7% and 87.6%, respectively, under optimal direct current (DC) of 1.5 mA for 1.5 min, followed by electroregeneration of resin and electrode.
The synthetic Cu (II) and Cd (II) contaminated water (CW) was prepared by adding CuCl 2 and CdCl 2 into tap water. Four concentrations of Cu (II) and Cd (II) (1, 5, 10 and 20 mg L −1) were used to study the effect of various initial metal concentration on the removal efficiency of the system.

Recent advancements in graphene adsorbents for wastewater
In another study, Yi et al. desorbed Cu(II) by 0.3 mol/L HCl and UO(II) by 0.3 mol/L HNO 3 from GO encapsulated polyvinyl alcohol/sodium alginate (SPG) hydrogel, and tested the reusability performance of the SPG with five cycles experiments. The removal efficiency for Cu(II) and UO(II) was decreased after the first adsorption-desorption cycle
The reduced natural waters and the large amount of wastewater produced by textile industry necessitate an effective water reuse treatment. In this study, a combined two-stage water reuse treatment was established to enhance the quality and recovery rate of reused water. The primary treatment incorporated a flocculation and sedimentation system, two sand filtration units, an ozonation unit, an

- Why is polyacrylamide important in wastewater treatment?
- The correct use of polyacrylamide will contribute to improving municipal wastewater treatment results, protecting water resources, and achieving sustainable development. In the wastewater treatment industry, polyacrylamide has become an indispensable agent.
- What is polyacrylamide used for?
- Polyacrylamide (PAM) is a high molecular weight polymer that comes in three types: cationic, anionic, and non-ionic. Its molecular chain contains a large number of covalent bonds, giving it excellent adsorption properties. As a result, PAM is widely used in municipal wastewater treatment, oil extraction, pulp and paper production, and other fields.
