The document describes a study on treating tannery effluent using groundnut shells. Tannery effluent contains high levels of pollutants like chromium, copper and nickel that contaminate water sources. The researchers prepared activated carbon from groundnut shells and used it to adsorb pollutants from tannery effluent. They characterized the activated carbon and analyzed pollutant levels in the raw and treated effluent. The treatment significantly reduced pollutant concentrations like chromium, chemical oxygen demand and biological oxygen demand. Using an agricultural byproduct like groundnut shells for treatment provides an inexpensive and effective alternative to existing costly treatment methods.

Treatment of Distillery Wastewater by Anaerobic MethodsIJERA Editor
One of the major environmental problems faced by the world is management of wastes. Industrial processes
create a wide range of wastewater pollutants; which are not only difficult but costly to treat. Characteristics of
wastewater and level of pollutants vary significantly from industry to industry. To control this problem today
emphasis is laid on waste minimization and revenue generation through by-product and energy recovery.
Pollution prevention focuses on preventing the harmful effect of generated wastewater on the environment,
while waste minimization refers to reducing the volume or toxicity of hazardous wastes by water recycling and
reuse, process modifications and by by-product recovery. Production of ethyl alcohol in distilleries based on
cane sugar molasses constitutes a major industry in Asia and South America. The world’s total production of
alcohol from cane molasses is more than13 million m3/annum. The aqueous distillery effluent stream known as
spent wash is a dark brown highly organic effluent and is approximately 12-15 times by volume of the product
alcohol. This highly aqueous, organic soluble containing residue is considered a troublesome and potentially
polluting waste due to its extremely high BOD and COD values. Because of the high concentration of organic
load, distillery spent wash is a potential source of renewable energy. The paper reviews the possibility of
anaerobic treatment of the distillery wastewater.

Immunizing Image Classifiers Against Localized Adversary Attacksgerogepatton
This paper addresses the vulnerability of deep learning models, particularly convolutional neural networks
(CNN)s, to adversarial attacks and presents a proactive training technique designed to counter them. We
introduce a novel volumization algorithm, which transforms 2D images into 3D volumetric representations.
When combined with 3D convolution and deep curriculum learning optimization (CLO), itsignificantly improves
the immunity of models against localized universal attacks by up to 40%. We evaluate our proposed approach
using contemporary CNN architectures and the modified Canadian Institute for Advanced Research (CIFAR-10
and CIFAR-100) and ImageNet Large Scale Visual Recognition Challenge (ILSVRC12) datasets, showcasing
accuracy improvements over previous techniques. The results indicate that the combination of the volumetric
input and curriculum learning holds significant promise for mitigating adversarial attacks without necessitating
adversary training.
