Abstract:

Results of model simulations indicate that without the assumption of COD loss, predictions of oxygen consumption and volatile suspended solids production are significantly over-estimated for biological excess phosphorus removal (BEPR) activated sludge systems (and to a lesser extent anoxic-aerobic systems). These systems apparently consume less oxygen and produce less volatile solids than aerobic systems for the same amount of COD removal. A general model for biological nutrient removal systems has recently been presented by Barker and Dold. Three mechanisms for COD loss are suggested, based o

The tofu industry is a type of industry that operates in the field of food processing from soybean raw materials. The tofu industry is dominated by small-scale businesses, most integrated into residential areas. The tofu industry has yet to process the liquid waste it produces. High environmental pollution can result in the death of aquatic biota due to lack of oxygen. This research aims to reduce BOD and COD levels that do not meet quality standards. Based on this, research was conducted to reduce the organic content in tofu liquid waste using pumice stone as a filtration medium. The research

Water is used every day in society and to be able to recycle this water we depend upon efficient wastewater treatment. It is vital to test the wastewater based on different parameters. One parameter is the Chemical Oxygen Demand (COD), which defines the amount of organic substances that can be chemically oxidized within the water. The Swedish standardized analytical method for COD (SS-028142), COD(Cr) is dependent on mercury, a substance which was banned according to Swedish regulations in year 2009 but is still used due to time limited dispensations.

Biological aerated filters (BAFs) are an emerging wastewater treatment technology designed for a wide range of municipal and industrial applications. BAFs utilize an inert media, either dense granular or floating, which supports biomass retention in the filter bed. BAFs offer an alternative to typical biological treatment processes; however, knowledge of the process is often limited, especially in the US market. Through various studies, process improvements were made for filter media selection, backwash protocols, and hydraulic load effects. During the summertime monitoring, seeded and u

Abstract:

The deteriorating water quality of the Kelani River over time has negatively affected environmental health and sustainability. This study aims to determine the relationship between land use types and its impact on the water quality within the Kelani River basin. The analysis utilized a dataset comprising 23 parameters related to water quality, spanning 17 sampling locations along both the primary river and its tributaries from 2003 to 2023. IBM SPSS Statistics (Version 26), was utilized for data analysis, focusing on 7 water quality parameters (pH, dissolved oxygen (DO), chemical oxygen demand

Abstract:

The inhabitants produce the sump waters and accumulate temporarily in the sumps. This is sewage that must be treated before it is discharged to surface waters. Slovak legislation does not allow the discharge of such waters into the soil. The possibilities of sump water treatment are given by the water management equipment of the given locality where sewage water is produced. The most common treatment method is transported at municipal wastewater treatment plants, which are, however, largely congested. In many cases, the sump water is no longer able to receive in WWTP. Another way is domestic w

Abstract:

This paper investigates the potential of graphene-coated sand as an advanced filtration medium for improving water quality and mitigating chemicals of emerging concern in treated municipal wastewater, aiming to enhance water reuse. The study utilizes three types of sand coated with graphene to assess the impact of surface morphology, particle shape, and chemical composition on coating and filtration efficiency. Additionally, sand coated with graphene and activated graphene coated sand were both tested to understand the effect of coating and activation on the filtration process. The materials w

Abstract:

In the global search for the right alternative energy sources for a more sustainable future, hydrogen production has stood out as a strong contender. Hydrogen gas (H2) is well-known as one of the cleanest and most sustainable energy sources, one that mainly yields only water vapor as a byproduct. Additionally, H2 generates triple the amount of energy compared to hydrocarbon fuels. H2 can be synthesized from several technologies, but currently only 1% of H2 production is generated from biomass. Biological H2 production generated from anaerobic digestion is a fraction of the 1%.

Abstract:

This reports on the results of the monitoring of water quality across 48 stations in the LMB. The report shows the water quality in the Mekong and Bassac Rivers was still of good quality with the slight improvement compared with 2016. There was only a small number of measurements of chemical oxygen demand (COD) and dissolved oxygen (DO) that violated the MRC Water Quality Guidelines for the Protection of Human Health (WQGH) and the MRC Water Quality Guidelines for the Protection of Aquatic Life (WQGA). Most exceedances were recorded in the Delta. Of a slight concern was the DO level at Chau Do
