Hospitals generate wastewater containing pathogens, pharmaceuticals, heavy metals and other pollutants. This wastewater requires specialized treatment to remove contaminants before discharge. A biological MBBR/IFAS process using Levapor carriers is an effective treatment method. The porous carriers adsorb inhibitory substances and pollutants, allowing specialized biofilm to develop and remove contaminants through biological and chemical processes. This results in consistently high quality effluent meeting discharge standards.

waste water treatment in hospitals

Tabish Malik

This document summarizes the wastewater treatment process at Sher-e-Kashmir Institute of Medical Sciences hospital in Srinagar, India. The wastewater treatment plant has two phases, with phase 1 including primary sedimentation, aeration, and secondary clarification and phase 2 including screening, grit removal, aeration, and secondary clarification. After treatment, effluent is sent to sludge beds and soak wells before final discharge to a nearby lake. However, the current facility is insufficient for fully treating hospital wastewater and poses health risks, as screens, grit, and sludge are not properly maintained or disposed of.

sewers and sewer netwrok - design construction and maintenance

Manish Goyal

This document discusses the design of sewer systems. It begins by classifying sewers into domestic, storm, and combined sewers based on what they are designed to carry. It notes the advantages and disadvantages of combined sewers. The document then discusses methods for estimating sewage flow rates, including population forecasting, per capita flow rates, and peak flow factors. It also covers stormwater runoff estimation and the rational method formula. Finally, it discusses some hydraulic design considerations for sewers, such as designing for partial flow rather than full flow due to gas generation in sewers.

Sharifah Ain

This document discusses the design considerations for sewer systems. It outlines the different types of sewers based on wastewater flow, and specifies design requirements like pipe sizing, slopes, depths, and velocities. Factors like population equivalent calculations, peak flows, hydraulic properties, and manhole levels are also summarized. The document provides guidance on planning and laying out sewer networks in accordance with relevant codes and standards.

1) The document outlines the design calculations for a sewage treatment plant for a mixed development project with 40 residential units and 18 commercial units. The population equivalent is calculated to be 293. 2) A rotating biological contractor (RBC) system is selected as the sewage treatment method since it is suitable for staged development, requires low land area, produces high quality effluent, and has low operation and maintenance costs. 3) Design parameters for the sewer reticulation pipes are provided, including a peak flow factor calculation, minimum pipe sizes and slopes, maximum infiltration rates, and manhole specifications such as location, depth, and gradient requirements.
