Abstract Wastewater from car wash stations of agricultural machinery is contaminated with mechanical impurities, oil products, pollution generated by exhaust gases, fertilizers and processing agents used in agriculture, as well as a large amount of surfactants. Purification of this wastewater to the quality required for their reuse allows organizing a circulating water supply scheme, which significantly reduces not only the negative impact on the environment, but also the need for clean tap water. This article describes the results of wastewater treatment from car wash stations of agricultural machinery on an electroflotator and post-treatment by filtration through various filter media, incl. through a sorbent made of modified rice straw - agricultural waste.

Silica is the most abundant components in the earth's crust and is made by way of synthesis for use in the application of technology. Silica are generally found commercially as alkoxysilane compounds (i.e such as tetraethylorthosilicate (TEOS), sodium silicate, and tetramethylorthosilicat). However, these compounds can have a negative impact on health. Thus, further approaches to find the source of silica that is safer, cheaper, and more environmentally friendly is inevitable. However, not all summary journals are thoroughly discussed the silica sources. Further, method of isolation and application of the silica from agricultural waste is limited. This paper reported studied several sources of silica derived from agricultural waste, such as rice husk, rice straw, corn cobs, and bagasse. In addition, this paper discussed also about the method of isolation of silica from agricultural waste, and its application as a catalyst.

Внедрение оборотного водоснабжения является важным фактором снижения негативного воздействия на окружающую среду промышленными предприятиями. В 2007 г. специалистами ЭКОС Групп были построены и введены в эксплуатацию очистные сооружения для сточных вод завода по производству минеральных удобрений. Вводу в эксплуатацию предшествовали полноценные опытно-промышленные испытания на пилотной установке производительностью 1 м3/ч. Предварительные пилотные испытания являются наиболее верным шагом при реализации проектов по возведению канализационных очистных сооружений. На пилотной установке были апробированы предлагаемые технологические решения: дозы химических реагентов, последующее осветление, фильтрация и сорбция на безнапорных фильтрах. В результате были определены технологические параметры, принятые к проекту, и основные показатели качества исходной сточной воды. Эффективность очистки при фильтровании через ершовый фильтр составила до 80%. Показана необходимость усреднения исходных сточных вод и использования ступени биологической очистки. По завершении работ заказчик получил надежные, простые в эксплуатации очистные сооружения, что позволило прекратить сброс сточных вод в городскую канализацию и сократить собственное водопотребление на производственные нужды. The introduction of recycling water supply is an important factor in reducing the negative impact of industrial enterprises on the environment. In 2007, experts from ECOS Group built and commissioned wastewater treatment facilities for a mineral fertilizer plant. Commissioning was preceded by full-fledged pilot tests in a pilot plant with a capacity of 1 m3/h. Preliminary pilot tests are a smart move in the implementation of projects for the construction of wastewater treatment facilities. The proposed process solutions were tested in the pilot plant: dosages of chemicals, subsequent clarification, filtration and sorption in gravity filters. As a result, the process parameters and the main indicators of the quality of raw wastewater were determined. The filtration efficiency in a ERSH was up to 80%. The necessity of raw wastewater balancing and the use of a biological treatment stage is shown. Upon completion of the work, the customer received reliable, easy-to-work treatment facilities; effluent discharge into the municipal sewer was ceased and the water consumption for the production needs was reduced.

Environmental pollution caused by the anthropogenic activities is a global challenge. Pollution due to discharge of untreated wastewater, contributes to it considerably. High expenditures for the treatment technologies can be considered as one of the major reason for improper wastewater discharge. Activated carbon provides an excellent solution for this issue as it can be used as a low cost wastewater treatment adsorbent. This paper review, types of activated carbon, their applications and recovery methods in wastewater treatment. Activated carbon from conventional waste such as agricultural waste, woody waste and non conventional waste such as municipal waste can be used as a low cost media for waste water purifications. Physical and chemical processes are used to improve the adsorption property of the activated carbon. H3PO4, KOH and ZnCl2 are the most frequently used chemicals for the activation process. Granular activated carbon, powdered activated carbon, activated carbon fibers and carbon clothes are the major physical forms of the activated carbon. These physical forms are important to maximize the adsorption process according to the purpose of usage. Activated carbon is used to remove heavy metals, dyes, COD, BOD, organic contaminants and volatile organic compounds in the waste water. Various recovery methods are applied to regenerate activated carbons. Among them, chemical, thermal, and bio regeneration methods are examined. Strengths, weaknesses, opportunities, threats related to use of activated carbon and future research priority areas are also discussed

The notion of reused water can evoke negative images. When further complicated by the public's lack of understanding of the water cycle, coupled with a widespread skepticism and distrust of technology, a much needed water supply strategy can easily become doomed. Much of the attitudinal landscape is beyond the control of water managers but the problem can be exacerbated by the vocabulary and images typically used to define water and wastewater treatment. The compartmentalization of water supply and wastewater treatment into different organizations has resulted in poor understanding of water cycle management which has a particularly negative impact on water reuse, which is made to sound unusual - and people have a tendency to fear things that are out of the ordinary and seemingly strange. The water industry has also disproportionately focused on the history of the water rather than its treatment and ultimate safety for its intended use. This presentation describes an approach to work through these issues in a manner that encompasses rational thought as well as emotion and feelings and shows that when the general public are given the opportunity to reframe their understanding of water and to have a more realistic view of water quality, they are drawn to different conclusions. If a lack of knowledge by the public about water is the single largest barrier to sustainable water management, then it is essential we do a better job of using language and imagery to create a deeper understanding of the water cycle and water treatment.

One of the reasons for the current global environmental crisis is the intense anthropogenic impact on water bodies, which results in their depletion and pollution. The source of the negative impact is, in particular, insufficiently treated wastewater from industrial enterprises. Depending on the technological processes used, toxicants can enter the water bodies along with the effluents, which pose a serious threat to them. The aim of the work is to consider the features of water supply and wastewater disposal of enterprises that make up the industrial hub of the city of Tambov. The work used methods of analysis of technical documentation and statistical reporting characterizing the qualitative and quantitative composition of wastewater. Water supply of the considered enterprises is carried out from the city water supply network and own artesian wells. All enterprises do not have full-fledged treatment facilities capable of carrying out a full cycle of wastewater treatment with bringing them to a standard clean state. The use of galvanic technologies in production requires preliminary cleaning at local treatment facilities. Then the wastewater goes to the city wastewater treatment plant, where it is processed together with the municipal wastewater. Normally clean and storm water flows directly into the surface water body. The largest enterprise of the industrial hub pumps its industrial effluents into deep aquifers. Over the entire period of its operation, over 52 million m3 of liquid toxic waste was injected. As a result, a zone of contaminated groundwater was formed under the enterprise and adjacent territories. In them, the excess of the maximum permissible concentrations for a number of parameters is constantly noted. Thus, this enterprise is a source of powerful, direct negative impact on groundwater and, indirectly, on surface water. This led to the emergence of a zone of sustainable environmental risk.

Water and sewage management in Poland has systematically been transformed in terms of quality and quantity since the 1990s. Currently, the most important problem in this matter is posed by areas where buildings are spread out across rural areas. The present work aims to analyse the process of changes and the current state of water and sewage management in rural areas of Poland. The author intended to present the issues in their broader context, paying attention to local specificity as well as natural and economic conditions. The analysis led to the conclusion that there have been significant positive changes in water and sewage infrastructure in rural Poland. A several-fold increase in the length of sewage and water supply networks and number of sewage treatment plants was identified. There has been an increase in the use of water and treated sewage, while raw sewage has been minimised. Tap-water quality and wastewater treatment standards have improved. At the same time, areas requiring further improvement—primarily wastewater management—were indicated. It was identified that having only 42% of the rural population connected to a collective sewerage system is unsatisfactory. All the more so, in light of the fact that more than twice as many consumers are connected to the water supply network (85%). The major ecological threat that closed-system septic sewage tanks pose is highlighted. It is pointed out that they are mainly being replaced by household wastewater treatment systems with ineffective filtering drainage. Furthermore, recommendations were also made for the future development of selected aspects of water and sewage management, including the legal and the political.

<p><em><strong>Composting of Rice Straw for Organic Fertilizer and Manufacturing Rice Husk Charcoal as Planting Medium in Soybean Demonstration Plot.</strong> Agricultural waste is the residue from an agricultural business activity, which if left unch</em>ecked can have a negative impact on the environment. Agricultural waste such as rice straw can be used for organic fertilizers because it has high potassium and lignin content. The purpose of this community service activity is to increase the knowledge and skills of the community and farmers about straw processing through the composting stage as organic fertilizer and burning rice husks into husk charcoal as a planting medium in soybean cultivation. Community service was carried out from July to August 2020 in Pengkok Village, Kedawung District, Sragen Regency, namely in the Subur and Sumber Agung farmer groups. Community service activities carried out are counseling or socialization of the use of straw and husk charcoal as organic fertilizer and planting media, then proceed with demonstrations or practices for making organic fertilizers and husk charcoal which are continued with planting soybeans in polybags with the application of compost and husk charcoal that have been made. The result of this service activity is that participants or farmer groups can make organic fertilizer from straw waste and husk charcoal independently and can be applied when cultivating soybeans in polybags as well as understanding the stages of making straw compost and burning husks into husk charcoal. The conclusion from the service activities that have been carried out is the understanding of the knowledge of community service participants about the methods or stages of composting in making organic fertilizer and making husk charcoal from rice husk waste for planting media as proven by farmers being able to make organic fertilizer from rice straw which initially becomes waste that is not optimal. used as compost which is made through the composting stage and the manufacture of husk charcoal using the burning method in a funnel and then applied in the soybean demonstration plot experiment in polybags.</p>

World Industry

At the present stage of development, the entire world industry has faced the problem of rational use of renewable natural resources, in particular the most efficient ways of wastewater treatment and the use of accumulated waste in the production process as a secondary raw material. In particular, the alcohol industry, as one of the components of food, medical, chemical and various industries,leads to the formation of huge amounts of waste, including wastewater. The food industry, like any other industry, has a negative impact on the environment. Water bodies are the most affected by the food industry. Almost the first place in terms of water consumption per unit of production is the production of alcohol. Consumption of large amounts of water leads to the formation of wastewater, which is highly polluted and adversely affects the environment. Due to the high chemical and biological consumption of oxygen, specific color and odor, suspended solids, low pH value, the purification of such waste in the filtration fields and discharge into water bodies is not possible. The purpose of our work is: 1) conducting the analysis of the alcohol industry potential in Ukraine in recent years, and methods of waste disposal as a potential source for the development of bioenergy. 2) environmental aspects of the alcohol industry modernization at present stage of development and implementation of modern wastewater treatment technologies.
