BACKGROUND, AIM, AND SCOPE Fishery wastewater treatment can be compromised due to seasonal production. The use of sequencing batch reactors is not completely successful, despite flexibility being one of the principal advantages. Most research on activated sludge is performed using synthetic wastewater to ensure a stable and constant feed. The current work compared biomass morphology and settlin...
The objective of this work was to evaluate the replacement of Gum Arabic for sodium chloride to reduce fat and organic contents in dairy wastewater using two low cost commercially available lipase preparations from animal source (Kin Master LKM and NuclearLNU). The best performance was achieved when lipase Nuclear (LNU) was used as catalyst. In addition, this lipase preparation has also lower c...
Greenhouse gas (GHG) emission can become a limiting factor in livestock farming development. Animal manure management systems in Taiwan differ from the model of the Intergovernmental Panel on Climate Change (IPCC) to represent the Far East and Asian region. This study was undertaken to establish GHG production data from anaerobic livestock wastewater treatment processes in Taiwan, and to clarif...
Energy generation from dairy industry wastewater was investigated using a dual chambered Microbial Fuel Cell by aerobic and anaerobic anodic metabolism, operating with initial COD concentration of 1600 mg/L and anolyte pH of 7 produced highest power density of 192, 161 mW/m(2) and volumetric power of 3.2, 2.7 W/m(3) with COD removal efficiency of 91% and 90%, respectively. The columbic efficien...
Increase in demand for milk and their products many dairies of different sizes have come up in different places. The dairy industry involves processing raw milk into products such as consumer milk, butter, cheese, yogurt, condensed milk, dried milk (milk powder), and ice cream, using processes such as chilling, pasteurization, and homogenization. The typical by-products of milk are buttermilk, ...
It has been proposed that livestock production effluents such as wastewater, airborne dust and manure increase the density of antimicrobial resistant bacteria and genes in the environment. The public health risk posed by this proposed outcome has been difficult to quantify using traditional microbiological approaches. We utilized shotgun metagenomics to provide a first description of the resist...
background: wastewater produced by a dairy in sanandaj is a major source of environmental pollution threatening the city. the dairy uses activated sludge treatment to remove organic pollution from the wastewater. the present study evaluated the performance of this process and its compliance with national requirements for chemical oxygen demand (cod), biochemical oxygen demand (bod), and total s...
Using algae as a feedstock for biodiesel has been considered for a number of years, but it has always had limitations, due mainly to the production methods used to grow and harvest the algae. In this project, we propose a novel attached growth method to produce the algae while recycling dairy farm wastewater using the microalga Chlorella sp. The first part of the work provided a feasibility stu...
background low-cost anaerobic sequencing batch reactor (asbr), which is widely used for controlling high-organic wastewater, is an effective method to remove chemical oxygen demand (cod). objectives the main objectives was evaluating the feasibility of using asbr in the treatment of synthetic dairy wastewater, determining its removal efficiency, and assessing the effect of temperature on operat...
