Bài báo này nghiên cứu khả năng xử lý amoni trong nước thải chăn nuôi lợn bằng phương pháp kết tủa MAP. Mô hình bao gồm 1 ngăn lắng, một phản ứng có kích thước 30x30x40 cm và thiết bị khuấy. Chất lượng được khảo sát 4 ngày từ 15/11/2022 đến 18/11/2022 với tần suất 3 lần/ vào 7h, 13h 19h. Khảo cho thấy tỷ lệ mol các chất tham gia Mg2+: NH4+ : PO43- = 1,2 là tối ưu nhất. vận hành mẫu tại 19h 16/1...

Minimal liquid discharge (MLD) in greenhouses minimizes the volume of discharged wastewater, thereby increasing effluent that may be reused. Sodium accumulation wastewater is often considered main bottleneck to achieving 100% reuse. Consequently, have begun adopting reverse osmosis (RO), most commonly used desalination technology for treatment. RO removes ions from indiscriminately, including m...

Batiaghata Upazila, Khulna District in south-west coastal region of Bangladesh is the mostly saline affected area, where agriculture activities are mainly dependent on rainfall. 23 water samples from surface water and shallow tube well (STW) were collected in the monsoon season and analyzed for physico-chemical properties to classify them according to salinity hazard. Electrical Conductivity (E...

The design and synthesis of efficient adsorbents for the recovery precious metals from secondary resources are great environmental economic significance. Herein, a magnetic sulfur-doped composite CoFe2O4@S–CoWO4 ([email protected]–CoWO4) is developed through hydrothermal method, which used to selectively recover gold in aqueous media. Significantly, [email protected]–CoWO4 exhibits best overall...

Globally, water quality indices (WQIs) are beneficial for evaluating groundwater and surface quality. The Canadian Council of Ministers Environment Water Quality Index (CCME WQI) was combined with the parametric values given by Directive 98/83/EC to investigate possible suitability resources human consumption on Rhodes Island. Chloride (Cl?), pH, calcium (Ca2+), electrical conductivity (CND), c...

Microbial fuel cell (MFC) systems are promising technologies for wastewater treatment and renewable energy generation simultaneously. Performance of a double-chamber microbial to treat synthetic swine containing sulfonamide antibiotics (SMs) was evaluated in this study. The MFC operated continuous modes at different conditions. Results indicated that the current successfully generated during op...

Evidences have shown that coastal water as habitat support various flora and fauna well nursery ground which highlight the importance of quality monitoring act basis for productivity fisheries. Therefore, objective this study is to analyse temporal spatial variations selected parameters in sergestid shrimp’s along Miri, Sarawak. Nine namely dissolved oxygen (DO), temperature, turbidity, pH, sal...

Phosphorus in water not only degrades quality but also leads to a waste of resources. In this study, adsorption thermodynamics and kinetics were used study the effect sponge iron on phosphorus removal, filtration bed was simulate removal polluted water. The results showed that maximum theoretical capacity modified increased from 4.17 mg/g 18.18 mg/g. After desorption with mol/L sodium hydroxide...
