We develop the idea of creating wastewater treatment facilities for biosphere compatible buildings with maximum-closed cycles with respect to water and energy. The idea started from experiments with closed-loop ecological Life Support Systems for space flights carried out in the 60s-80s last century. Water recycling is accomplished by functioning the microalgae-bacteria human ecosystem. One of ...

Anthocyanins from black bean canning wastewater were isolated and purified on a laboratory scale by column chromatography, and then identified by high performance liquid chromatography electrospray tandem mass spectrometry. Dynamic adsorption and desorption were performed in glass columns packed with Sepabead Sp700 to optimize the purification process. Different temperatures during adsorption a...

abstract population increase, limitation of water resources, and increasing volume of municipal wastewater, has caused the necessity of wastewater reuse. application of wastewater on soils seems to be the most economical method of its disposal and by percolating wastewater through the soil, its chemical quality is improved. for this purpose, a greenhouse experiment was carried out with polyethy...

Presented in this paper is a graphical technique for freshwater and wastewater minimisation in completely batch operations. Water minimisation is achieved through the exploitation of inter- and intra-process water reuse and recycle opportunities. In the context of this paper, a completely batch operation is one in which water reuse or recycle can only be effected either at the start or the end ...

Solar-driven water purification is considered as an effective and sustainable technology for treatment using green solar energy. One major goal practical applications to improve the evaporation performance by design of novel photothermal materials, with optimized heat localization transport pathways achieve reduced energy consumption vaporization. Recently, some emerging materials like polymers...

Abstract: Co-cultivation of microalgae and microbes for pollutant removal from sewage is considered as an effective wastewater treatment method. The aim of this study is to screen the optimal photoperiod, light intensity and microalgae co-cultivation method for simultaneously removing nutrients in biogas slurry and capturing CO₂ in biogas. The microalgae-fungi pellets are deemed to be a viable ...

In this study, the enzyme activities and their relationships to domestic wastewater purification are investigated in four different types of subsurface-flow constructed wetlands (CWs), namely the traditional horizontal subsurface-flow, horizontal baffled subsurface-flow, vertical baffled subsurface-flow, and composite baffled subsurface-flow CWs. Results showed that the urease activity in the c...

This review describes medium and high molecular weight organic material found in wastewaters from pulp and paper industry. The aim is to review the versatile pollutants and the analysis methods for their determination. Among other pollutants, biocides, extractives, and lignin-derived compounds are major contributors to harmful effects, such as toxicity, of industrial wastewaters. Toxicity of wa...

A typical negative impact on water resources for mining companies engaged in blasting operations is the discharge of quarry and mine contaminated with nitrogen compounds. The solution problem under consideration assumed an integrated approach based use partially flooded abandoned workings already available at enterprise as bioengineered structures. article substantiates confirms possibility usi...
