Biological Nutrient Removal In Municipal Waste Water Treatment

This civil engineering seminar topic gives an insight into Biological nutrient removal in municipal waste water treatment which is a much needed technology. Main problem is the rising concentration of nutrients. Nitrogen and phosphorus are the primary causes of eutrophication. Most recognizable manifestations are algal blooms. Symptoms are low dissolved oxygen, fish kills, murky water and depletion of flora and fauna.

Study Of Road Accidents in India

Road accidents are one of the causes of disability, injury and death. India has the highest road traffic accident rate worldwide with over 140000 deaths annually, beating even China. Every hour nearly 14 lives are lost due to road accidents. Most accidents occur during peak hours considered an unsafe or dangerous time due to complex flow pattern of vehicular traffic. Thus traffic engineers have to undertake a big responsibility of providing safe traffic movements to the road users and ensure their safety. Road accidents cannot be totally prevented but by suitable traffic engineering and management the accident rate can be reduced to a certain extend. This civil engineering seminar topics gives an insight into causes and remedies of Road Accidents in India.

Effects of liquefaction induced ground failure on bridges

Liquefaction is process by which water-saturated, unconsolidated sediments are transformed into a substance that acts like a liquid which can undermine the foundations and base courses of infrastructure like bridges. It can cause serious damage. Liquefaction can be classified into two. They are Flow Liquefaction And Cyclic Mobility. Flow Liquefaction - Static shear stress exceeds shear strength of liquefied soil. Cyclic Mobility - Static shear stress are slightly less than liquefied shear strength, but static and dynamic stresses are greater than shear strength of liquefied soil.

Glare and Night Time Driving

Glare is caused by Harsh uncomfortably bright light. It’s a sensation in response to light that can take a number of forms. Results from bright, steady, dazzling light or from shiny surfaces. Can also caused by very bright foreground or by light reflected by fog or snow. Glare affects both day & night driving performance. Effects of glare on drivers are classified as Discomfort glare and Disability glare. Disability glare is also known as physiological glare. It is created by bright light. Its comes from light scattering in the ocular media. Reduce driver’s ability to perform visual task. Glaring light scattered in the eye can be expressed as superposition of uniform luminance onto retinal image. Discomfort glare is caused by bright light. It cause discomfort or annoyance. Scale of discomfort glare was used by DeBoer. It is influenced by 3 factors. They are location of glare source, luminance of background and luminance & size of glare source. This civil engineering seminar topic gives an insight into causes of Glare during Night Time Driving.

Construction chemicals for waterproofing in concrete structures

Permeability is one of the main factors that can affect the durability of the structure. Permeable structures can result for various reasons such as low cement content, poor compaction too much water during concrete mixing etc. The passage of water through cracks ,joints, voids, and inter connected capillaries in the mass concrete makes the concrete previous, ultimately  leads to poor protection of structures, increases the rate of alkali aggregate reaction and also accelerates the rate of corrosion in the steel.

Performance of geosynthetic filters in treatment of urban storm water runoff

Current urban infrastructure is highly reliant on impervious surfaces, including roadways, parking lots, and building rooftops. Rainfall that strikes these surfaces cannot infiltrate into the soil and subsurface and rapidly becomes surface runoff. They mobilize and transport particulate matter and other pollutants. Storm water control measures (SCMs) currently in use for storm water treatment are retention ponds, detention basins, wetland ponds, and grass swales, which requires large land area.

Geotextiles in Transportation Applications

Geotextiles is defined as permeable textile materials used in contact with the soil, rock, earth etc as an integral part of  civil engineering  project, structure, or system. Different type of Geotextiles are Filtration, Drainage, Separation, Reinforcement and Sealing.

Nano Filtration in water supply systems

Generally, there are four types of membrane processes. They are microfiltration, ultrafiltration, nanofiltration and reverse osmosis. Microfilter(MF) - Operating Pressure(psi) is less than 30. Types of materials removed are Clay, bacteria, large viruses, suspended solids. Ultrafilter(UF) - Operating Pressure(psi) is between 20 and 100. Types of materials removed are Viruses, proteins, starches, colloids, silica, organics, dye and fat. Nanofilter(NF) - Operating Pressure(psi) is between 50 and 300. Types of materials removed are Sugar, pesticides, herbicides, divalent anions. Reverse Osmosis(RO) - Operating Pressure(psi) is between 225 and 1000. Types of materials removed are Monovalent salts.

Use of Geogrids in Flexible Pavement

Due to the increased difficulty in the development and maintenance of pavement with limited financial resources, Unavailability of high quality materials and Geogrid gained increasing acceptance in road construction. Various process involved in Geosynthetics commercial construction aid are Separation, Reinforcement, Filtration, Drainage and Containment.
