activated sludge or extended aeration treatment involves a continous system where aerobic biological growths are mixed with waste water and then separated in a gravity clarifier. therefore, waste treatment system such as the activated sludge system depend on the activities of communities of living organism. in this study, an attempt was made on the indentification of the bacterial population in...

The Mayang River in Jember Regency has a length of approximately 145.50 km which is the longest river and can irrigate an area 5,860 hectares. use by community produce waste, both domestic agricultural livestock waste. Waste that enters directly into bodies cause decrease water quality create pollution load. Therefore, measurement load capacity was conducted. samples were taken using grab sampl...

The textile industry is one of the industries that generate a high volume of waste water. Strong colour of the textile waste water is the most serious problem of the textile waste effluent. The disposal of these wastes into receiving water causes damage to the environment. With regard to their colour removal by conventional treatment methods lead to severe water pollution, thus developing cost ...

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...

The bioremediation of industrial waste water by macroalgae is a sustainable and renewable approach to the treatment of waste water produced by multiple industries. However, few studies have tested the bioremediation of complex multi-element waste streams from coal-fired power stations by live algae. This study compares the ability of three species of green freshwater macroalgae from the genus O...

Saline waters from underground coal mines in Poland often contain natural radioactive isotopes, mainly 226Ra from the uranium decay series and 228Ra from the thorium series. More than 70% of the total amount of radium remains underground as radioactive deposits due to spontaneous co-precipitation or water treatment technologies, but several tens of MBq of 226Ra and even higher activity of 228Ra...

The large volumes of water used in rinsing operations in the plating industry may contain cyanides, chromium, nickel, and zinc, resulting in a substantial loss of valuable plating chemicals. From an economic viewpoint, particular consideration should be given to measures that will permit recovery of chemicals and water for reuse. In view of the wide variety of conditions found in plating practi...

On the basis of key ways of oily waste treatment in Russia which has been described in the article and on the example of oil-contaminated soil (OCS) treatment there can be considered two most widespread technologies: bioremediation and thermal recovery. We developed the process flow sheet of the equipment (UT-2S) for industrial oily wastes treatment on the basis of high temperature air tight de...

Currently, one of the major and global problems is treatment wastewater from organic industrial waste, such as textile waste. The solution to this problem production environmentally friendly adsorbents based on plant raw materials. increasing use natural resources, biomass recovery, waste in past decade, has attracted attention an number scientists. Activated carbon (AC), used remove micro-poll...
