In Present research ,the validity of a solar distiller which is made of two parts ( a solar tank and a solar distiller ) has been tested and distillered the water of one water- trench in Baghdad was treated using this equipment which produced pure water with an average of ( 1106 ml/m2 .h) during the day and (222 ml/m2 .h ) at night .The total water produced is thus ( 1324 ml/m2 . h ) . The laboratorial tests of the samples water before distillation showed that the stream water contained T.P.C/ 1ml =2900 ( Total Content Of Bacteria ) , T.C/100ml >1600 T.C (Total coli form) , F.C /100 ml>1600 (Fecal Coli Formand ) and E. coli /100ml>1600 . The total percentage of salt in water trench before distillation was T.D.S mg/l 1886 \ After water treatment and distillation , the Total Content of Bacteria ( T.P.C) was decreased to T.P.C / 1ml = 210 , (Total coli form) T.C /100 ml = Zero , ( Fecal Coli Formand) F.C/100ml= Zero and E.coli /100ml = Zero . In and, the total percentage of salt after distillation T.D.S was decreased to 105 mg/l . The results of this research show that water distillation using solar distiller is a successful and efficient process led to decreasing T.C.P 93.8% and killing all types of harmful T.C , F.C. and E. coli bacteria. )By analyzing the samples of sterile water using the solar distiller in the laboratories of the Ministry of Health and Environment- Central Environmental Laboratory as shown in Table (6)).

Purification Of Water

Drinking Water scarcity is one of the leading issue in our growing world. The atmospheric air contains large amount of water in the form of water vapor, fog, mist etc.In which 30% of water is wasted.Under this situation the climatic conditions of many regions are suitable for generating water. This moisture content is processed by condensation principle to produce fresh water that may be used as distilled water in laboratory and further purification leads to drinking water purity level. Here cooling is produced by Peltier effect and hot air is passed to cooling medium and when it reaches dew point it start condensing water from air. The obtained water from air contain excess of contaminants such as bacteria, nitrate, nitrate, odor, ammonium etc.., these toxic substances are remove by using biofiltration method. In this research filter medium is constructed by extraction of Activated charcoal from coconut waste. . The main aim of our project is utilization of renewable resources that are already available in nature and turn back this energy into water. This project is design a device that can convert humid air directly into clean water.

Water Purity

Water purity is not taken for granted in the Semiconductor Industry. Ultra high purity water (UPW) is analyzed continuously in-line for particles and resistivity. Routine samples are automatically taken for total organic carbon (TOC), boron, silica and dissolved oxygen. Less routine analyses, such as metals, are done off-line. Metal content of UPW water is well below the detection limits of ICP-MS even with a pre-concentration step. As a result, metals content may vary in the water without being detected. These variations may affect device performance and yield while the root cause may go undetected.

Water Purity

This review article provides an overview of activities in the rapidly developing field of water purification via photocatalytic methods and focuses on the removal of nitrate ions with simultaneous removal of the hole scavenger. Many of the issues associated with provision of potable water in the developing world may be resolved by the use of simple physical methodologies such as filtration. However, many of the issues associated with water purity in the developed world involve complex, stable molecules present at low concentrations that are nonetheless capable of producing toxic effects in plants and animals and that require more demanding removal technologies. Photocatalytic methods can be operated remotely and often show minimal production of undesired side products. Titania alone shows limitations, not only in terms of the slow rate of photoreduction of nitrate but also in terms of selectivity and the need to employ radiation in the UV region due to the magnitude of the band gap. Key challenges may be defined as: reducing the band gap/increasing absorption in the visible region, enhancing the adsorption capacity/access to the surface sites and reducing the rate of hole/electron recombination. The present article will focus on the use of titania-based materials that involve metal co-catalysts for nitrate reduction. This article is part of a discussion meeting issue ‘Providing sustainable catalytic solutions for a rapidly changing world’.
