Some organisms that can bioremediate are bacteria, fungi, and fast plants. There are also a variety of different methods of bioremediation. This includes phytoremediation, which is the manner which plants removing toxins from the environment and mycoremediation is used by fungi to eliminate toxins and harmful substances from the environment. For bioremediation, it 's harmless and helpful in many ways. However, some organisms are good or bad when they bioremediate.
One method of this technology is phytostabilization, where plants are used to immobilize metals and store them in their below-ground organs and/or soil. , Hyperaccumulators may be used to remove metals from the soil during the phytoextraction and concentrate them in the above-ground organs (Galal and Shehata
Activated sludge treatment has many challenges that one of the biggest being the footprint it demands. Activated sludge plants are costly to construct and occupy substantial land areas. Primary and Secondary processes rely upon vast tracts of land for large and costly settling tanks and aeration basins. Due to high populations constantly increasing, municipal wastewater treatment plants need to expand their capabilities. Advanced technologies that use smaller process basins by increasing the amount of biomass per unit volume via the addition of media for biofilm attachment (such as IFAS and MABR) or increasing the biomass concentration (such as
Amarant has a hyper accumulator that capable to uptake high concentration of contaminant without damaging its growth. (Khoramnejadian, S.,2014). The mechanism involved in phytoremediation is plant could take up heavy metal, solvent, aromatic carbon, and other contaminants from soil, sludge and water. However phytoremediation is not suitable for high contaminated sites, limited to the surface area. the purpose of this study is to evaluate the precise concentration of Amaranth in order to give the best result in degrading the polutant level in soil that contaminate
The conventional methods are expensive and are not very effective. Thus bioremediation is the need of the hour. Bioremediation uses living organisms to degrade or remove the pollutants from a contaminated site. It is defined as “Treatment that uses naturally occurring organisms to break down hazardous substances into less toxic or nontoxic substances” (EPA). The environment has the inbuilt tendency to degrade the waste which is known as intrinsic bioremediation.
Most commonly they enter surface runoff or leachate, but because they have relatively low toxicity to fish and invertebrates, acute toxicity is likely only when they are deliberately or accidently applied directly to water bodies. Some herbicides cause a range of health effects ranging from skin rashes to death. Phenoxy herbicides are often contaminated with dioxins such as TCDD which can cause cancer. Commercial herbicide use generally has negative impacts in bird
INTRODUCTION The increase in population causing higher demand in agricultural commodities for both crop and animal. The increase in population is also associated with the environmental problem currently occurred (Aneja et al., 2006). Due to higher demand in both crop and animal product, farmers throughout the world have sought the problem by increasing productivity. However, due to the fact that the demand need to reach satisfactory, another main problem in animal agricultural industry is unmanaged waste. Waste from animal agricultural industry mainly the manure are very hard to utilised because the amount of manure is too much to handle since the amount of animal itself is quite high.
Leading advantage of the lowered pH is that antimicrobial effect can be perceived against a variety of pathogenic organisms. Moreover, the low pH acts as a caustic agent bringing about hemostasis by creating an artificial clot. But, disadvantage is that the low pH causes inactivation of other biologically active agents like thrombin, which limits its
Some authors prefer to separate the physical/mechanical damages from the chemical. Although the damages' processes are different, they come most of the time one with another. For example, cyanobacteria growing on stone surface produce substances, which enhance the stone's disintegration and allow their "hyphae" to penetrate into internal layers, causing mechanical damages to the inner part of the stone. This is why, here, they are considered to be only one kind of alterations. Aesthetic changes often imply a bio-contamination of the artefact, the formation of new compounds on the surface of the material or a major alteration of the compound constituting the artefacts considered.
Fouling Fouling is an accumulation of undesirable material on the surface of solid . Fouling is not only the chronic problem of heat ex-changers but it is also one of the major problem that occur in whole industries. Because of that, the extra cost is required for the additional fuel consumption, cleaning action, maintenance, loss of production etc. There are several types of fouling that are caused by the different reasons. Biological fouling: This fouling is caused because of the growth of different organism within the fluid which is mostly deposit out.
