Modeling climatic effect on physiochemical parameters and microorganisms of Stabilization Pond Performance

Abstract

The present study was carried out to evaluate the relationship between physiochemical parameters, microorganisms, wastewater and climate in Stabilization Pond Performance. This study performed as a post-treatment after the secondary wastewater treatment using extended aeration in Rashid city, Egypt. The model of the extended aeration as secondary wastewater treatment was developed based on the combination with lagoon after the secondary sedimentation basin. The Climatic functions have an important impact on the mechanism of ponds as it actuates vertical mixing of the pond contents. The interaction between bacteria, algae and other organisms are the main idea of oxidation pond treatment beside the relationship between the climatic functions, physiochemical parameters and microorganisms biomass. The removal of biodegradable organic loads specially nitrogen and phosphorous are perfectly happens in oxidation maturation ponds which reflects a higher treatment efficiency of the sewage by 98%-99% of Biological Oxygen Demand (BOD), Chemical Oxygen Demand (COD) and heavy metals. The study included some recommendations aiming at improving both water quality and its recycling in plants irrigation.

Comprehensive Understanding of Hydrogeochemical evaluation of seasonal variability in groundwater quality Dynamics in the Gold Mining Areas of Osun State, Nigeria

“…Beyond this, aquatic animals need an ambient pH of 7 or higher to survive and maintain unhindered physiology, development, and metabolism [82, 83]. Beyond 8.5, pH would significantly contribute to the growth of algae that would kill fish [84] Furthermore, in extremely acidic water, heavy metals dissolve more readily. Because many heavy metals become significantly more hazardous when dissolved in water [9, 10], this is crucial information.…”

“…The isolation and enumeration of bacteria indicative of fecal contamination such as total coliforms (TC), FC and fecal streptococci (FS) are carried out using the most probable number method, and it is a statistical method used to estimate the viable numbers of bacteria in a sample by inoculating broth in 10-fold dilutions and is based on the principle of extinction dilution. It is often used in estimating bacterial cells in wastewater (Yagoubi et al 2000;Phuntsho et al 2016;Daee et al 2019;Ali et al 2020).…”

“…Concentrations of nickel and chromium ions showed a significantly reduction upon treating the plant with the Schiff base rather than that treated with the raw sludge with 82.75 and 70.96% respectively (Figure 11). Schiff base treating sludge showed also promising results regarding copper and zinc ions [58,59].…”
