Changes in Water Quality Parameters in Different Processes of Surface Water Treatment Plant (Case study: Tehranpars Water Treatment Plant)
Background and purpose: Water treatment is of great importance in human life, due to the contamination of water resources. Therefore, continuous evaluation of the performance of water treatment plants is necessary to minimize contamination within the treatment plant in order to create optimal conditions. Materials and methods: A cross-sectional descriptive analytic study was performed in Te...
متن کاملThe Effect of Different Concentrations of Plant Growt Regulators on Micropropagation of Kalanchoe blossfeldiana cv. White
Shoot tips from actively growing, greenhouse maintained plants of Kalanchoe blossfeldiana were cultured in vitro for shoot proliferation and root initiation on Murashige and Skoog (MS) basal medium supplemented with NAA and BA, both in concentrations of 0.00, 0.50, 1.00 and 2.00 mg l-1. Results showed that the maximum plantlets height (7.012 cm), node number (4.516), root number (8.860) and roo...
متن کاملWater recovery in space.
In the absence of recycling, water represents over 90% of the life-support consumables for a manned spacecraft. In addition, over 90% of the waste water generated can be classified as moderately or slightly contaminated (e.g. shower water, condensate from the air-conditioning system, etc.). The ability to recover potable water from moderately contaminated waste water hence enables significant s...
متن کاملInvestigation of Trihalomethanes in Drinking Water of Abbas Abad Water Treatment Plant
Introduction: Chlorination is the most common and successful method for disinfection of drinking water, especially in developing countries. However, due to the probability of formation of disinfection by-products especially Trihalomethanes (THMs) that are known as hazardous and usually carcinogenic compounds, this study was conducted to assess the investigation of THMs in drinking water of Abba...
متن کاملSelective coagulant recovery from water treatment plant residuals using Donnan membrane process.
Fouling of membrane surfaces by particulate matter and large organic molecules is relatively common for pressure-driven membrane processes, namely, reverse osmosis (RO), nanofiltration (NF), and ultrafiltration (UF). Donnan membrane process (DMP) or Donnan Dialysis is driven by electrochemical potential gradient across a semipermeable ion exchange membrane. Theoretically, DMP is not susceptible...
