For chemical industries, fresh water availability is a pre-requisite for sustainable operation. However, in many delta areas around the world, fresh water is scarce. Therefore, the E4Water project (www.e4water.eu) comprises a case study at the Dow site in Terneuzen, The Netherlands, which is designed to develop commercial applications for mild desalination of brackish raw water streams from various origins to enable reuse in industry or agriculture. This study describes an effective two-stage work process, which was used to narrow down a broad spectrum of desalination technologies to a selection of the most promising techniques for a demonstration pilot at 2–4 m³/hour. Through literature study, laboratory experiments and multi-criteria analysis, nanofiltration and electrodialysis reversal were selected, both having the potential to attain the objectives of E4Water at full scale.

The increasing variety of industrial activities in Indonesia resulted in ground water reserves in some areas experiencing drought. Exploitation of ground water by industry and the community in some big cities like Jakarta, resulting in the decrease of ground water and ground water quality reduced caused sea water instrusion. While the potential of wastewater produced by industrial and household waste high today. Based on the matters mentioned above and see the use of ground water that will be even greater in the future, then one of alternative that a lot of attention in many countries around the world are using wastewater reuse, particularly urban domestic wastewater (municipal wastewater) as a source of raw water for water supply. BPPT as a government office has made use of wastewater reuse technology, however, when the performance of the appliance is not working properly for it is necessary for re-evaluation and selection of wastewater reuse technology for better and sustainable. Keywords : Wastewater Reuse Technology, Domestic Wastewater, Water Consumption Survey

PV plants are increasing all over the world and they are becoming a distinct part of electric grids. Due to abundance of solar irradiation and almost constant amount of it in certain geographical latitudes, selection of proper capacity of PV plants depends mostly on available places for the site. in this paper, important measures for safe connection of a PV plant in terms of voltage requirements are addressed and several guidelines are introduced for this purpose. In addition, simulation results are included to prove some of the mentioned suggestions. a general algorithm is finally proposed to show the directions for safe connection of PV plants.

The book brings together critical considerations and experiences linked to the work of the author, lecturer in restoration at the Florence University Faculty of Architecture, as supervisor of degree theses on restoration. The reflections concern teaching Restoration as a subject, the conditions within which the knowledge and culture of restoration can ripen within our universities and the most recent problems encountered by both the discipline and restoration projects. In the first part of the publication, these aspects are set out in broad and more precisely conceptual and methodological terms in chapters and themed paragraphs which also act as a guide to drawing up degree theses on restoration, as well as a contributing to the didactics and efficiency of the specific discipline. This is followed by a selection of degree theses on restoration discussed in recent years which show the route from the principles, general problems and intervention criteria for every case study to drawing up a project. They are projects that deal with analysis methods and techniques, surveys, specialist restorations, regeneration, and the relationship between old and new. In short, the projects are what gave the final stage in the university education meaning and substance, also in order to acquire fundamental keys to restoration culture and activities in the world after university.

Globalization is being experienced throughout the world with its impact also observed in architecture, even in traditional villages of Indonesia. Some of them have, however, been able to maintain their identity such as the mass-space pattern of the customary village of Bali Aga Mountains in Bali which is discovered not to have changed. This research was, therefore, conducted to determine the relationship between the activities of the traditional society and their mass-space patterns using the customary village of Bali Aga Tenganan Pegringsingan as the case study. This involved the selection of respondents purposively and collection of data using cross sections by identifying unchanged buildings, taking photos, videos, drones, and through direct interviews in the field. The data obtained were analyzed qualitatively based on structuring theory or ordering principles and the results confirmed the mass-space pattern in Tenganan Pegringsingan village was built due to the close relations with the traditional activities of the society. The findings can be used in developing architecture by local governments as policymakers as well as academic architects and practitioners, and the wider society. © 2020 Lydia Dewi Setiawan, Purnama Salura, Bachtiar Fauzy
