Main Technique

One of the major problems in this century refers to the availability of potable water, necessary to the survival of populations. The world population is continually increasing and natural resources are proportionally decreasing, and the development of potable water production techniques demands intensive efforts. Electric power requirement is also necessary to the development of nations. Desalination processes are widely used in countries with low offer of potable water. Technologies nowadays in use are multi-stage-flash distillation (MSF), multi-effect distillation (MED) and reverse osmosis (RO) process. In MSF and MED processes, the main technique is distillation. Reverse osmosis technique relies on the osmotic principle, in which a solvent passes through a membrane. Since the middle of 1950, these desalting techniques are widely used mainly in the Middle East countries, where water shortage is almost absolute. Although uncommonly conceived, discussing the implementation of desalination processes in association to cogeneration systems in Brazil is a necessary task for the long-term planning. In this way, this paper proposes to reviewthe successful experiences presented in the literature as a way of  establishing how electric power and fresh water production can be produced from seawater desalting processes in an optimized way. Another objective pursued in this paper is stimulating more attention to this matter, that deserves discussing the skill staff formation and the know-how of such technologies in the strategic planning to the water resource management, specially because these investments require a considerable time for human resources development and the knowledge of the most adequate technology to be implemented for the integration of desalting and cogeneration units.

Dissolved Air Flotation (DAF) has become increasingly important in the field of potable water treatment, as a preferred option for treating upland and stored lowland waters. This paper outlines the development of dissolved air flotation (DAF) in potable water treatment, the benefits and disadvantages and the recent advances that has taken the process technology from an art to a science.

Penerapan teknologi tepat guna tentang proses pengolahan air siap minum dengan menggunakan metode filtrasi, adsorpsi dan reverse osmosis telah dilakukan. Rancangan alat  pengelolaan air siap minum menggunakan kombinasi filtrasi-adsorpsi meliputi saringan pasir lambat (terdiri dari pasir silika, arang aktif, ijuk, kapas, dan kerikil) membran selulosa, granula karbon, karbon aktif, membran RO (reverse osmosis), dan lampu ultraviolet untuk desinfikasi. Penentuan beberapa parameter fisik (bau, warna), kimia (pH, Fe, nitrit, amonia, BOD5, COD, DO) dan biologi (bakteri E-coli) dari sumber air (irigasi) dan air hasil pemurnian dilakukan di Laboratorium Kimia Universitas Mataram dan Balai Laboratorium Kesehatan Pengujian dan Kalibrasi Provinsi NTB. Air siap minum yang dihasilkan memiliki kualitas sesuai dengan baku mutu air minum Peraturan Menteri Kesehatan Nomor 492/Menkes/Per/IV/2010 Tanggal 19 April 2010. Hasil uji organoleptik menunjukkan bahwa masyarakat menyukai air hasil pengolahan dan merespon positif terhadap alih teknologi pengolahan air. Pembangunan sentra pengelohan air siap minum diharapkan menjadi edukasi bagi masyarakat mengenai perilaku hidup bersih dan sehat. Implementation of appropriate technology on the process of potable water using filtration, adsorption and reverse osmosis methods has been done. Its design used a combination of filtration-adsorption includes slow sand filters (consisting of silica sand, activated charcoal, palm fiber, cotton, and gravel) cellulosic membranes, carbon granules, activated carbon, RO (reverse osmosis) membranes, and ultraviolet for disinfection. Determination of several physical (odor, color), chemical (pH, Fe, nitrite, ammonia, BOD5, COD, DO) and biological parameters (E-coli) of purified water were conducted at Chemical Laboratory of Mataram University and Health Laboratory Testing and Calibration Center of West Nusa Tenggara Province. The potable water produced has quality according to the quality standard of drinking water Regulation of the Minister of Health No. 492/Menkes/Per/IV/2010 Date April 19, 2010. The organoleptic test showed that the community responds positively to the knowledge transfer of water treatment technology. The construction of potable water center is expected to educate the public about clean and healthy living behaviorKata kunci: filtrasi, adsorpsi, reverse osmosis, air sungai, air siap minum
