This article examined the characteristics of zeolites from the Chankanai and Daubabinsk deposits. In the field of water treatment, the purpose of investigating natural zeolite from the Chankanai and Daubabinsk deposits as a sorbent presents new opportunities and prospects, as this raw material is little studied. The effectiveness of the sorbents was assessed based on the results of the water specifications according to the following criteria: methods for determining the total hardness of water; methods for measuring the mass concentration of total iron in water; methods for the determination of chloride in water; methods for the determination of nitrogen-containing substances in water; methods for determining the dry residue content of water; methods for determining the sulphate content of water; on hygiene requirements and water quality control. Zeolite modifications were aimed at improving their adsorption properties, increasing the efficiency of pollutant removal and developing optimal methods of using zeolites in water filtration. Modified zeolite from the Chankanai and Daubabinsk deposits showed high efficiency as a filter. When it was used to treat natural water, which normally contains high hardness and alkalinity, the best results were achieved with zeolite from the Chankanai deposit. In terms of Fe+ and Cl content, the best results were achieved using zeolite from the Daubabinsk deposit.

Experimental studies on stratification were conducted on a waste stabilization pond system at the University of Nigeria, Nsukka, Nigeria. This was done to ascertain the effect of stratification due to sunlight on pond parameters. An experimental approach was adopted which involved pouring wastewater into a glass column apparatus and exposing to sunlight for 7, 14, and 21 days. The statues of 16 physicochemical and microbiological parameters were investigated in the three strata under consideration. Analysis of the samples collected at depths A, B and C, 30cm apart, starting from the top indicated different values of temperature, pH, and nutrients. Maximum values of temperature (32.9 0C), pH (7.9), turbidity (3.46 NTU), and iron (1.86 mg/l), were recorded at the top layer; while the concentration of conductivity (906 μS/cm), total dissolved solids (589 mg/l), BOD5 (400mg/l), ammonia (290 mg/l), total coliform (126,000 cfu/100ml), and E. Coli (99,000 cfu/100ml) were highest at bottom layer. Conductivity, total dissolved solids, turbidity, iron, phosphorus and nitrates fell within World Health Organization (WHO) guidelines. A combination of sunlight with high pH and oxygen concentrations is needed for sunlight to have very significant effects. It is recommended that WSPs be designed with the consideration given to pond dimensions that will provide a wider surface area for sufficient sunlight and oxygen to be acquired.

“…There are various types of WSPs: aerobic, anaerobic (APs), facultative (FPs), and aerobic maturation ponds (MPs) [22]. Moreover, they have different treatment and design characteristics [23]. High-quality effluents can be obtained by providing them in series or parallel [24].…”

In Wastewater Stabilization Ponds (WSPs), baffle walls (BWs) have the dual benefit of reducing area requirements and increasing contaminant removal efficiency up to a certain threshold. However, this advantage is mitigated by the increased demand for construction materials, highlighting the need for optimization. Effectively optimizing WSPs to suit diverse climatic regions can substantially alleviate nationwide wastewater treatment challenges. This study focuses on optimizing WSPs across seven distinct climatic regions in Turkey. In the initial phase, a comprehensive analysis was conducted using design spreadsheets for the WSPs to determine the best configuration based on traditional methodology (TM). The results demonstrated a significant decrease in WSPs area and hydraulic retention time (RT), validating the effectiveness of BWs provision. However, this approach requires additional time and effort. Subsequently, mathematical modeling (MM) was used to further reduce the time required for the optimization process. Using the interior-point algorithm in MATLAB and the generalized reduced gradient (GRG) algorithm in MS Excel Solver, both algorithms within MM effectively decreased the WSPs area and RTby approximately 10%, while decreasing the required concrete volume by approximately 5% compared with TM. As other algorithms may yield better optimization, they can be investigated by developing specialized software for WSPs. Doi: 10.28991/CEJ-2023-09-11-014 Full Text: PDF
