The Revitalization of Makassar Urban Drainage System Based on Eco Drainage Retention Pond

Historical Perspectives of Urban Drainage

Historically, urban drainage systems have been viewed with various perspectives. During different time periods and in different locations, urban drainage has been considered a vital natural resource, a convenient cleansing mechanism, an efficient waste transport medium, a flooding concern, a nuisance wastewater, and a transmitter of disease. In general, climate, topography, geology, scientific ...

A Framework of Web-GIS for Urban Drainage Network System

Combined with the GPRS (General Packet Radio Service) technology, Geographic Information Systems (GIS) extends its abilities from static to dynamic working environment for urban drainage network. In this paper, a framework of Web-GIS for the urban drainage network management system is presented. This three-layer system framework is based on the J2EE technologies. The principles of data structur...

Studying the Effect of Cationic Starch- Anionic Nanosilica System on Retention and Drainage

Nanoparticles are widely used in the papermaking industry as retention/ drainage aids, usually in conjunction with a high mass cationic polyelectrolyte such as cationic starch. However, little convincing knowledge of their role and mechanism in the wet-end system is yet found. This work focused on the role of nanosilica on papermaking wet end system in response to some processing parameters (dr...
