11	Identifying Untapped Potential: A Geospatial Analysis of Florida and California’s 2009 Recycled Water Production Archer, Jana E., Luffman, Ingrid, Joyner, T. Andrew, Nandi, A. 01 June 2019 (has links) Increased water demand attributed to population expansion and reduced freshwater availability caused by saltwater intrusion and drought, may lead to water shortages. These may be addressed, in part, by use of recycled water. Spatial patterns of recycled water use in Florida and California during 2009 were analyzed to detect gaps in distribution and identify potential areas for expansion. Databases of recycled water products and distribution centers for both states were developed by combining the 2008 Clean Water Needs Survey database with Florida’s 2009 Reuse Inventory and California’s 2009 Recycling Survey, respectively. Florida had over twice the number of distribution centers (n 1/4 426) than California (n 1/4 228) and produced a larger volume of recycled water (674.85 vs. 597.48 mgd (3.78 mL/d1/4 1 mgd), respectively). Kernel Density Estimation shows the majority of distribution in central Florida (Orlando and Tampa), California’s Central Valley region (Fresno and Bakersfield), and around major cities in California. Areas for growth were identified in the panhandle and southern regions of Florida, and northern, southwestern, and coastal California. Recycled water is an essential component of integrated water management and broader adoption of recycled water will increase water conservation in water-stressed coastal communities by allocating the recycled water for purposes that once used potable freshwater.

12	Spatiotemporal Analyses of Recycled Water Production Archer, Jana E. 01 May 2017 (has links) Increased demands on water supplies caused by population expansion, saltwater intrusion, and drought have led to water shortages which may be addressed by use of recycled water as recycled water products. Study I investigated recycled water production in Florida and California during 2009 to detect gaps in distribution and identify areas for expansion. Gaps were detected along the panhandle and Miami, Florida, as well as the northern and southwestern regions in California. Study II examined gaps in distribution, identified temporal change, and located areas for expansion for Florida in 2009 and 2015. Production increased in the northern and southern regions of Florida but decreased in Southwest Florida. Recycled water is an essential component water management a broader adoption of recycled water will increase water conservation in water-stressed coastal communities by allocating recycled water for purposes that once used potable freshwater.

13	Zdravotně technické instalace a plynovod v polyfunkčním objektu / Sanitary technical installations and gas pipeline in a multifunctional building Bartek, Vojtěch January 2020 (has links) Diploma thesis deals with sanitation installations and gas installations in polyfunctional building in Miroslav. Polyfunctional building has four overground floors and one basement. The apartments are located on all overground floors and the offices are located on first over-ground floors. In the theoretical part discusses about the recycling of water and its use.
14	Återvunnet vatten : använda renat avloppsvatten i processen / Recycled water : use purified wastewater in the process Ek, Emmelie January 2021 (has links) Fältstudien gjordes för att utreda om det var möjligt att använda renat, filtrerat avloppsvatten för polymerberedning och i längden även som övrigt processvatten på Ellinge reningsverk. Testerna utfördes i fullskala med både vatten från mellansedimenteringen och slutsedimenteringen. Genom omfattande provtagningar och analysering av resultaten visade det sig vara en fungerande metod utan negativ påverkan på polymerlösningen och slamavvattningen. Det krävs dock mer arbete och ytterligare reningssteg såsom desinficering för att implementera det renade avloppsvattnet på hela vattensystemet. / The field study was done to investigate whether it was possible to use purified, filtered wastewater for polymer preparation and in the long run also as other process water at Ellinge treatment plant. The tests was performed in full scale with both water from the intermediate sedimentation and the final sedimentation. Through extensive sampling and analysis of results, it proved to be a working method without a negative impact on the polymer solution and sludge dewatering. However, more work and addiotional purification steps such as disinfection are required to implement the treated wastewater on the entire water system Sludge polymer sludge drainage technical water drinking water waste water recycled water Slam polymer slamavvattning brutet vatten dricksvatten återvunnet vatten tekniskt vatten avloppsvatten Natural Sciences Naturvetenskap Environmental Sciences Miljövetenskap Water Treatment Vattenbehandling
