ABSTRACTThe need for clean water consumption continues to increase in line with the current population and industry growth. The canned industry is one of the industries that consume a considerable amount of water for the production process, while the availability of clean water sources is very limited, both in quantity and quality. One alternative solution to the problem above is by building a wastewater treatment plant into reusable water (recycling) to meet the needs of the washing process in the industry. This paper discusses the testing of wastewater recycling installations into clean water in a canned industry in Jakarta. The process of recycling wastewater is divided into several stages, namely chemical processes for pH control, biological processes of activated sludge, biofilter, and filtration. Afterward, the wastewater is filtered using a reverse osmosis membrane. The test results show that the water quality of recycling wastewater and filtered wastewater using RO membranes could produce pure water quality. The use of water for the process in the canned industry is large enough for canned washing processes. Therefore, by using the recycling technology, the use of water, especially for the washing process, can be saved up to 100%.Keyword : wastewater reuse, reverse osmosis, can industriesABSTRAKKebutuhan akan konsumsi air bersih terus meningkat sejalan dengan pertumbuhan penduduk dan industri saat ini.

There is an ever increasing need to provide clean and portable drinking water in developing countries because of the poor quality of water, which causes various water borne diseases killing millions of infants and elderly people every year. There have been a lot of recent developments in the field of solar enabled water distillation where pure water is being generated. But a majority of the system use some type of external energy source for the system to run on which might make it efficient but can cause dependence on energy sources. The power of the Sun can be effectively harnessed and used as heat and light source for efficient steam generation. One of the challenges is to develop a low cost system which can perform at par with the best and extravagant systems. This paper investigates the performance of the solar distillation system when activated carbon nanoparticles are used along with brine and other sources of impure water so as to obtain clean water. The activated carbon nanoparticle which are an efficient and cheap mode of water purification enhanced the productivity of the system by 190% when compared to saline water due to its steam generation properties. A solar simulator of 1KWm2 was used to simulate the sun. Various parameters like the variation of air flow on condensation rate, height of fluid on vapor production rate and the temperature variation of the system are evaluated. Parametric studies of the effect of water quality and salinity were performed. It was determined that the optimum output rate of distilled water was 240 grams (6000gday.m2) was determined by the system from the parametric studies and the system is feasible and cost effective to be used in real world application. All of these standout features make the system a low cost option which can tackle the clean water dilemma in developing countries.

Wild And Scenic Rivers

The National Wild and Scenic Rivers Act protects less than ¼ of a percent of the United States’ river miles, focusing on free-flowing rivers of good water quality with outstandingly remarkable values for recreation, scenery, and other unique river attributes. It predates the enactment of the Clean Water Act, yet includes a clear anti-degradation principle, that pollution should be reduced and eliminated on designated rivers, in cooperation with the federal Environmental Protection Agency and state pollution control agencies. However, the federal Clean Water Act lacks a clear management framework for implementing restoration activities to reduce non-point source pollution, of which bacterial contamination impacts nearly 40% of the Wild and Scenic Rivers. A case study of the Musconetcong River, in rural mountainous New Jersey, indicates that the Wild and Scenic Rivers Act can be utilized to mobilize and align non-governmental, governmental, philanthropic, and private land-owner resources for restoring river water quality. For example, coordinated restoration efforts on one tributary reduced bacterial contamination by 95%, surpassing the TMDL goal of a 93% reduction. Stakeholder interviews and focus groups indicated widespread knowledge and motivation to improve water quality, but resource constraints limited the scale and scope of restoration efforts. The authors postulate that the Partnership framework, enabled in the Wild and Scenic Rivers Act, facilitated neo-endogenous rural development through improving water quality for recreational usage, whereby bottom-up restoration activities were catalyzed via federal designation and resource provision. However, further efforts to address water quality via voluntary participatory frameworks were ultimately limited by the public sector’s inadequate funding and inaction with regard to water and wildlife resources in the public trust.

Abstract Various human activities have led to the consumption of large quantities of pure water, which has led researchers to find efficient and economical methods for desalinating seawater and water containing impurities. In this review paper, solar energy where it is permanent, abundant and environmentally friendly, to produce pure water was discussed using a new solar distillation device, representing the paper’s novelty. The distillation was designed and used in the way led to increase efficiency and improve productivity by adding a solar collector to the system and equipped with a tank containing phase change material (PCM). It has a low melting point and can change the phase by absorbing the system’s latent heat to maintain the system’s temperature. Which contributes to increasing the distillation period even after sunset, thus increasing the daily productivity of freshwater. Using phase change materials will increase distillation hours from (3-4) hours after sunset, increasing the amount of production between (75 - 90) %.

The tropical region is often considered as a region where the sun shines intensely and the temperature varies at certain times of the year. In the case of Congo, the average weather condition is considered cool, however, there have been cases where the temperature reached up to 43° C. It is therefore imperative for buildings in this region to take into account the temperature variation while considering the comfort of the users. During the design and construction of the Bank of Belgian Congo, the availability of data to assist the architect Maurice Houyoux in meeting the challenge of the region was unavailable. The architect had to be creative in planning and overcoming the challenges posed by the environment. This paper seeks to examine the issues confronted by Maurice Houyoux and the design solutions he provided to ensure that the building was functional and responded to the tropical challenges. In undertaking this study, a historical approach was adopted through the review of relevant literature on the building and designs within the period of the development of the bank. An observation method was also deployed to verify some of the information found in the literature. The findings are presented using pictures and sketches to explain some of the key issues relevant to the design of the bank. The findings showed that despite the reduced number of published data for designing in such a region, the architect was able to examine the existing buildings and discuss with users of other constructions to obtain relevant data. The findings also showed that the building was able to respond to peculiar requirements to be functional. The paper concludes that the local building materials and traditional builders can be used to achieve a contemporary building that fits into the context towards sustainable architecture.

The paper focuses upon the control over environmental pollution of water bodies by human waste products in urban areas, which can be carried out by monitoring hydrobiological indi-cators. In the course of study undertaken in May 2017 and 2018 there was assessed the ecological and sanitary status of the Volga and Kutum rivers that flow on the territory of Astrakhan. Samples were taken at four stations; the choice of station location was determined by the presence of pollutant sources: proximity of the city market or the power plant. Quantitative and qualitative indicators of the state of phytoplankton were used as hydrobiological indicators; the total number of bacteria and the total content of coliform bacteria were evaluated as microbiological indicators. During the study period the ecological and sanitary state of water was rated as satisfactory. The number of algae taxa increased insignificantly (by 3 units), diatoms predominated in the number of genera and number. Despite the presence of 4-5 species of pure water representatives in the investigated waters, the sanitary and bacteriological situation at all the studied stations was found unfavorable; the water was characterized as polluted and dirty. In 2018, there was registered deterioration of water quality compared to 2017, while the calculated saprobity index in the Kutum river indicates the water quality improvement downstream. The increasing value of the water saprobity index in the Kutum river indicates a tendency toward the growing level of organic pollution and necessitates a comprehensive analysis of hydrobiological indicators for systematic monitoring the aquatic environment.
