Treatment of controlled discharge leachate by coagulation-flocculation: influence of operational conditions

Khaled Djeffal et al.

Summary: The study aimed to optimize the operational conditions of coagulation-flocculation process for leachate clarification, testing different coagulants and agitation methods. pH adjustment was crucial for treatment success, with a significant reduction in turbidity achieved by adjusting coagulant dosage, stirring speed, and time. Bacteriological analysis showed differences in microbial content depending on the coagulant used. Additionally, ultrasound waves improved leachate treatment efficiency compared to mechanical agitation, resulting in optimal clarification at specific temperatures and BOD5 levels for different coagulants.

Characteristics of organic matter removed from highly saline mature landfill leachate by an emergency disk tube-reverse osmosis treatment system

Chuanwei Wu et al.

Summary: The study evaluated the effectiveness of an emergency disk tube-reverse osmosis (DTRO) treatment system for highly saline landfill leachate in China. The system achieved over 83% water recovery rate, reduced the electrical conductivity of effluent, and effectively removed carbonaceous and nitrogenous pollutants. The DTRO system also successfully removed salts and refractory organic matter, showing potential for managing environmental risks in landfill leachate treatment.

Effect of ammonia stripping and influence of contaminants in zinc plating wastewater

Satoshi Morikubo et al.

Summary: This study investigated the effect of ammonia stripping on plating wastewater to remove ammonia, finding that the effectiveness of ammonia removal depends on pH and air flow rate, and the presence of zinc increased the removal effect. The addition of EDTA decreased the removal effect, but an excess amount increased it. Overall, the results indicate that ammonia stripping is effective in zinc wastewater treatment.

Mechanism and kinetics of adsorption and removal of heavy metals from wastewater using nanomaterials

Simranjeet Singh et al.

Summary: Nanomaterials have been developed for the removal of heavy metals in wastewater, including zero-valent, carbon-based, and nanocomposite materials. Various synthesis methods are used, and removal mechanisms involve chemical precipitation, adsorption, ion exchange, among others. Factors like pH, temperature, contact period, and dosage play crucial roles in controlling the adsorption processes.

Activation of peroxymonosulfate by cobalt doped graphitic carbon nitride for ammonia removal in chloride-containing wastewater

Jingwei Hao et al.

Summary: The cobalt doped graphitic carbon nitride catalytic system activating peroxymonosulfate was established for the oxidation of ammonia, achieving a high removal efficiency for ammonia and a good total nitrogen removal efficiency. The sulfate radical generated during the process reacted with chloride ions to produce chloride radical, which was identified as the main radical species for the transformation of ammonia to nitrogen gas. Additionally, the catalyst exhibited good stability and recyclability.

Sequential coagulation and heat activated persulfate-peroxide binary oxidation process for landfill leachate treatment

Emine Can-Guven et al.

Summary: This study investigated a sequential treatment of landfill leachate including coagulation and binary oxidation processes. The research optimized the chemical coagulation process and examined the factors affecting the binary oxidation process to achieve high removal efficiencies. The results showed that the binary processes were more effective than single processes, reaching significant removal efficiencies under optimal conditions.
