Sewage Water Treatment Plant for Hingna

A sewage water treatment plant is necessary to receive and treat waste water (Domestic, Commercial, and Industrial). Its objective is to be convert harmful waste water to safe water environmentally and treated effluent and treated sludge suitable for reuse and disposal such as farm fertilizer. The characteristics of waste water have been performed followed by design of sewage treatment plant. The present study includes design of sewage treatment plant and analysis of waste water – PH value, Total Dissolved Solids (TDS), Total Suspended Solids (TSS), Biochemical Oxygen Demand (BOD), Chemical Oxygen Demand (COD), Total Solids (TS), Hardness, Chloride, Acidity, Oil, Fats and grease etc. The sample collection of waste water has been done in many times in a day to obtain an average value of major parameter. Followed by values of this parameter, calculations are done for designing the units of sewage treatment plant and layout is prepared for the same

Complex Alumina-Ferrous Coagulant for Effective Wastewater Purification from Hydrogen Sulfide

The article provides an overview of studies on the causes of the formation of hydrogen sulfide in anaerobic conditions of urban sewage systems and methods for neutralizing toxic reagent sulfur-containing compounds. It is noted that the presence of sulfur compounds and organic components in sewage flow leads to the formation and release of hydrogen sulfide into the atmosphere of settlements. Three main categories of methods for purifying sewage wastewater from hydrogen sulfide are presented. In this work, a complex alumina-ferrous coagulant has been developed from Kazakh raw materials. Based on natural ferruginous diatomite and middlings of sintered alumina, a complex alumina-ferrous coagulant has been synthesized, which is effective in purifying wastewater from hydrogen sulfide, accelerating the processes of sedimentation and clarification of sewage slurries. Experimental results also show that with the supply of increased amounts of coagulant, oil and oil films disappear from the surface of the cylinder, an almost complete purification of effluents from hydrogen sulfide compounds occurs, and the color of the liquid part is greatly reduced. In addition, the advantage of the developed reagent is that it is presented in the form of fine powder and can be easily dosed and added to a canalization pump station to interact with diluted hydrogen sulfide and be transported to sewage fields. Compared to other proposed methods in previous works, the reagent is suitable to be used directly in sewage systems such as sewage waters treatment plants and collectors to prevent hydrogen sulfide emission into the air atmosphere of populated areas, as well as at city sewage water treatment stations after air tanks and before secondary clarifiers to obtain better purified water suitable for watering agricultural plants.

Biological Importance and Phytochemistry of Neptunia oleracea Lour: A Mini Review

Neptunia oleracea is an important medicinal plant used in treating various ailments in different countries. The plant contains chlorophyll-related compounds, amino acids, vitamins, etc. The presence of pheophorbide a and its related compounds make this plant a promising antitumor plant. The plant is used for sewage water treatment and is also utilized in nitrogen fixation in a wetland ecosystem. The present review emphasizes the traditional uses, biological activites and phytochemistry of N. oleracea.

Retechnologization of biological sewage water treatment facilities using mathematical modelling

The efficiency of sewage treatment plants is an urgent problem of the designed and operating stations. In modern conditions, efficiency is understood as the operation of facilities in which operating costs are minimized, facilities provide standard cleaning, and the company implements measures to modernize and improve energy efficiency and trouble-free operation. The article deals with the comparative analysis and selection of the most optimal scheme of biological sewage water treatment of existing sewage water treatment plants. The indicators of the efficiency of functioning and permissible loads on treatment facilities in the design of aeration tanks for biological sewage water treatment are determined. The results served as the basis for the creation of a mathematical model, with the help of which it is possible to calculate the parameters of the biological treatment system and optimize the process of biological sewage water treatment at existing treatment facilities. Mathematical modeling allows you to reduce the cost of designing and operating treatment facilities, to guarantee the degree of treatment in accordance with the requirements and standards for the discharge of treated sewage water into a reservoir for fisheries purposes.
