In general, strong positive correlations were found between the expression of 34 target genes. Adrenergic receptors, and some correlated genes, can be responsible for anomalies in pigmentation. This paper highlights the use of the combined culture system in municipal wastewater treatment. Removal of nutrients was significantly increased in properly inoculated combined culture system.

Release of organic matter from Chlorella biomass decreased the COD removal performance. Fouling occurred on the ion-exchange membranes under practical condition, Reversible fouling occurred on the CEM, Irreversible fouling occurred on the AEM. Through composting, biosolids can be converted to a soil conditioner provided pathogen control is ensured. Carbonized rice hull is a promising bulking agent for composting, while OFMSW can provide more organic matter needed for achieving higher peak temperatures.

Augmenting with T. The organic solvent pretreatment promotes the bioconversion of the organic solid waste. A low acid concentration increases the hydrogen production. Lactate production is favoured by high acid concentration and temperature of the pretreatment. Treatment of hydrometallurgical effluents by nanofiltration membranes for acid recovery. Application of Solution-Electro-Diffusion Model to determine membrane permeances. Achieving sustainable water—energy relationship is especially important for semi-arid regions.

Water consumption due to electricity generation can reach up to 8. Between and m3 of water is found to be consumed per GWh of electricity generated at cooling systems. The thermally altered zone thermal plume is a key aspect for land management of GSHPs. Current desalination technologies present certain limitations associated with brine management.

CDI operational conditions similar to EDL capacitors might become a solution for brine volume reduction. Innovative operating procedure utilizes a concentrated brine stream as a washing solution during the salt desorption phase. A high energy efficiency in the adsorption—desorption cycle was obtained using the electrolyte replacement procedure.

The synergy between anions and cations is understood for their enhanced antimicrobial activity. Up to thousandfold enhancement of antibacterial and antiviral activity in drinking water by this technique. Enhancement makes disinfection of water affordable, compact and adaptable to multiple purification systems. A decrease in consumption of inorganic ions reduces health risks caused by disinfection by-products DBPs.

Thus DBPs and bioaccumulation related issues can be handled efficiently. This understanding of synergy helps to speed up the disinfection process. Harnessing the photochemistry of chloramines can provide a promising approach for water reuse and treatment. Photo cata lytic membrane bioreactors pMBR were investigated for bacterial disinfection and fouling control. The signal molecules were significantly inactivated by the photo cata lytic treatment.

Biofouling was well inhibited during continuous pMBR operation. Water facilities consume a large amount of electrical power. The components of water networks mostly pumps and tanks represent an incomparable opportunity for joint operation of water networks and power systems. These components are well suited for being responsive loads to power systems because water is storable. Water permeability tests, hydrophilicity, and surface morphology characterizations were conducted.

Air quality indicates some pollution next to the highway. Demand shedding through aeration control can exploit the wastewater treatment plant WWTP flexibility to help maintain the power system grid balance and reduce operational costs. The reactions and settling process combination is not considered in traditional WWTP models, but it could play an important role in the modelling of demand response DR strategies and their effects on the plants.

Miscanthus is a suitable alternative for energy biomass. Particularly, in cultivation area that is prone to flooding. Current commercial Miscanthus can survive in the winter-flooded environment. There is no significant difference in yield and other physiological development.

Observed height and tiller number have no differences between winter flooded and non-flooded ground. Superior performance of phosphorous removal was achieved by ion exchange process with respect to chemical precipitation. The ion exchange resins required a lower dosage to ensure compliance with the effluent limit.

Shock loading at noon resulted in the worst treatment performance by overloading the plant. Drip feeding based on ammonia control ensures a higher degree of flexibility by adjusting the leachate flow. Digestate microfiltration tests were carried out under different operating conditions, to fine tune the best working conditions of the equipment. Then it was possible to distribute the microfiltered digestate in fertigation on growing maize through drip lines without causing blockage.

To achieve a robust and optimal design of water distribution networks, both hydraulic constraints and reliability concerns must be met. This paper aims at employing multi-objective particle swarm optimization MOPSO algorithm for reliability-oriented design of a water distribution network. We use Pareto-front analysis to make a compromise between cost and reliability satisfaction. Energy and water nexus stress drives innovation in technology, financing models, business models, and partnerships.

There are new platforms to accelerate nexus innovation that leverage the skills and experience of successful entrepreneurs from outside the energy and water sectors. New business and financial models are needed to solve energy and water nexus stress challenges. New partnership models are emerging to foster cross-industry and entrepreneurial platform collaboration.

Darwin Scheduler model based on fast messy genetic algorithm is utilized to best schedule the operation of the pump stations. Van Zyl, which is a well-known water network, is used to simulate the aforesaid model. FMGA leads to the reduction of the maintenance costs. Membrane-aerated biofilm reactor MABR is an energy efficient biological wastewater treatment process, based on passive aeration: by diffusion of oxygen through membranes, which also support an aerobic biofilm.

Energy consumption was measured and averaged over 2 months of operation. The results show the energy consumption for operation of the secondary treatment with MABR amounts to 0. In the second case, the energy consumption for operation of the secondary treatment was below 0. By consuming very low energy at small treatment capacities, MABR supports the most important principles in water and energy efficiency: reduced energy for treatment and local water reuse.
