Abstract.Growth Textile industry from year to year demands high creativity both design and color. The process production of textile industry especially dyeing can not separated from the use of clean water and high wastewater pollutant produced. With Zero Water Discharge principle, the industry is expected to reduce the amount of waste discharged into the environment. There are many water, and wastewater recycling technology processes. However, in Indonesia conventional wastewater processing is still widely encountered, limited to aerobic and anaerobic active sludge processes, chemical coagulation - flocculation processes, as well as activated carbon - filtration processes. This study examined the process of wastewater recycling in the management of bio-chemical waste and using activated carbon aplication for post treatment. This recycling process could improve process efficiency and saved production costs. Carbon active process decreased COD contamination up to 96%, with contact time 20 minutes. The study and research of potential wastewater recycling on conventional bio-chemical-carbon active processing expected to be an inspiration for industries, and the public to do waste water recycling.

Granulated Activated Carbon

Biologically enhanced granular activated carbon (BAC) is a promising wastewater post-treatment to produce a purified effluent suitable for recycle in the textile industry. Three small pilot scale filters were used, filled with three media (two adsorbent media and one non-adsorbent), to compare two different GACs and quantify the biomass contribution to organic removal and colour abatement. A demonstrative scale filter was tested in parallel to evaluate the influence of hydraulic parameters on BAC process efficiency. Biomass contribution was significant when an acclimated biofilm grew on particles; in all cases, wastewater decolorising was due to physical-chemical adsorption only; higher hydraulic load negatively affected the polishing process. Laboratory and semi-industrial scale tests were performed on textile fibres and fabrics using samples of the effluent from the demonstrative filter. The tests confirmed the suitability of the treated water for textile reuse.

In Harelbeke a Water Treatment Plant with a capacity of 15,000 m3/day, using Schelde river water has been in operation since April 1995. The treatment process comprises nitrification, dephosphatation by direct filtration, storage into a reservoir, direct filtration, granular activated carbon filtration and disinfection. The design of the three-layer direct filters was based on pilot experiments. The performance of the plant during the five years of operation is discussed. It was found that the removal of atrazin by activated carbon depends on the water temperature.

Based on the PPP efficiency system which consists of allocation efficiency, process efficiency, and individual efficiency, we use qualitative comparison analysis of fuzzy sets to study the efficiency advantages of the public-private partnership under the Chinese scenario. The findings are as follows: (1) like public-private partnerships, Chinese-style PPPs have also failed to achieve cooperation. (2) High allocation efficiency can be achieved if competition in bidding processes can be ensured; when bidding procedures cannot be guaranteed to compete, alternatives to high allocation efficiency are either privatized or allocated directly to enterprises that can enable economies of scale; individual effort is a source of allocation efficiency. (3) Competition and economies of scale are necessary conditions for high process efficiency. The private sector’s ownership of assets is a sufficient condition for high process efficiency. (4) High individual efficiency can be achieved if individual efforts can be ensured, and high individual efficiency can also be achieved by the competition of bidding procedures or economies of scale when it is impossible to ensure high levels of individual effort. Privatization is the perfect incentive for high individual efficiency when the competition in the bidding process, individual efforts, and economies of scale cannot be guaranteed.

The Difference

ResumoO Agronegócio é responsável por cerca de ¼ das riquezas geradas anualmente no Brasil. Dentro deste universo a cultura cafeeira é responsável por cerca de 10% do volume total das exportações deste setor. A viabilidade da produção cafeeira em qualquer escala depende fortemente da agregação de qualidade no produto final, eficiência nos processos e o controle dos custos da atividade. Os pequenos e médios cafeicultores, de maneira geral, ainda carecem de uma estrutura administrativa que lhes permita conhecer e gerencia adequadamente suas finanças, apesar de existir uma consciência da necessidade do conhecimento e gerenciamento dos custos de produção o que ainda vemos são as finanças das atividades sendo misturadas com as finanças pessoais, impossibilitando qualquer tipo de análise precisa e ainda, uma forte tendência de subjugar os custos e despesas e de inflacionar os resultados finais, mesmo que estes não estejam explícitos. Fatores como má administração do fluxo de caixa ou até mesmo menosprezo por pequenas despesas no cálculo do resultado podem ser o diferencial entre aqueles produtores que prosperam e aqueles que têm de deixar a atividade.

Abstract Agribusiness is responsible for about ¼ of the wealth generated annually in Brazil. Within this universe, coffee culture is responsible for about 10% of the total export volume of this sector. The viability of coffee production on any scale strongly depends on the aggregation of quality in the final product, process efficiency and cost control of the activity. With the administrative modernization of the activity efficiency is gained, and with the efficiency gain opportunities for greater financial gain arise, either through cost reduction or revenue increase. Small and medium coffee farmers, in general, still lack an administrative structure that allows them to know and manage their finances properly, although there is an awareness of the need for knowledge and management of production costs. What we still see is the finances of the activity mixed with personal finances, precluding any kind of precise analysis and yet a strong tendency to subjugate costs and expenses and to inflate final results, even if they are not explicit. Factors such as poor cash flow management or even contempt for small expenses in calculating income may be the difference between those who thrive and those who have to leave the business.

Paper and Paper Products in the printing and publishing sector, production costs have increased due to the recent dependence on imports. At this point, Paper and Paper Products Printing and Publishing sector has been preferred and the leading companies in the sector have been tried to be determined by multi-criteria decision making methods. In this study, the financial performances of the paper and paper products printing and publishing sector traded in Borsa Istanbul between the years of 2012-2017, which is one of the multi criteria decision making methods, are the most important decision making methods, PROMETHEE (Preference Ranking Organization Method for Enrichment Evaluation and COPRAS (Complex Proportional Assessment) methods. The research sample consisted of 14 companies listed in the BIST. Firstly, the financial ratios used in multi-criteria decision making methods were explained and then the application steps of TOPSİS, PROMETHEE and COPRAS methods were included. During the calculation of financial ratios, the financial statements of the related companies between the years 2012-2017 were used in the light of the data obtained from the Public Disclosure Platform. As a result of the research, the 6-period performance of the companies have rewieved, between the years 2012-2017 was evaluated with 10 financial ratios and the results were compared.
