Domestic wastewater

In the research, three kinetic models including first order, Grau second order, Stover Kincannon model were studied to describe the process kinetics of the ammonium removal in the AX. Stover Kincaanon proved to be the most suitable for simulating ammonium performance in fixed bed reactor using Felibendy.

With the rapid growth of economic development, the circular economy has been raised in many international environmental and socio-economic conferences and forums nowadays. The recycling of plastic waste was one of those aspects. This paper studied the potential of directly reusing plastic bottle caps as bio-carriers in moving bed bioreactors without further waste processing.

This research investigates an innovative approach to augmenting the current evaporation pond disposal approach used in Australia, and other regions around the world. The augmentation involves the incorporation of solar plate collector technology. The technology is widely used across the world to collect solar power to drive a range of commercial and domestic applications, most commonly solar hot water systems.

The main objective of this study was to examine the efficacy and capacity of using hydroponic systems in municipal pollutant removal at household scale. Three pilot scaled hydroponic systems [dimension for each system: 4.5 m (L) x Φ 114 mm] were installed to investigate the optimal age of vegetable, planting density and retention time for household wastewater treatment, respectively.

The paper indicates that Pistia stratiotes were used for wastewater treatment about twenty days with 0 individual/tank, five individuals/tank, seven individuals/tank, nine individuals/tank. Every experiment was conducted three times in the same way with 140 L for each tank. The experimental result shows that the amount of Pistia stratiotes increases and reach the highest quality in Treatment 3 on the 15th day.

As the global population grows and many developing countries modernize, the importance of water supply and water treatment becomes a much greater factor in the welfare of nations. In similar fashion, the need to address both domestic and industrial wastes generated by these nations moves higher on the scale of importance. Clearly, in today’s world the competition for water resources coupled with the unfortunate commingling of wastewater discharges with freshwater supplies creates additional pressure on treatment systems....
