اندازه گیری و کنترل tds(total dissolved solids) آب، در صنعت، کشاورزی، دامپروری و بهداشت از اهمیت بالایی برخوردار است. سیستم طراحی و ساخته شده در این مقاله، با نصب بر روی دستگاه های تصفیه آب صنعتی و خانگی ، tds آب را اندازه گیری، نمایش و کنترل می نماید. تکنولوژی ساخت سیستم اندازه گیری tds به گونه ای است که اثر مخرب دما بر اندازه گیری را جبران می کند. همچنین با شرح آزمایش های متعدد انجام شده در پ...
introduction: a total dissolved solid (tds) is an important indicator for water quality assesment. since the composition of mineral salts and discharge affects the tds of water, it is important to understand the relationships of mineral salts composition with tds. materials and methods: in this study, methods of artificial neural networks with five different training algorithm,levenberg-marquar...
Distillery spentwash contains high chemical oxygen demand (COD), biological oxygen demand (BOD), color, total dissolved solids (TDS) and other contaminants even after biological treatment. The effluent can’t be discharged as such in the surface water bodies or land without further treatment. Reverse osmosis (RO) treatment plants have been installed in many of the distilleries at tertiary level ...
The Salton Sea reservoir, located in Imperial County, Ca., is unique in several ways from most liquiddominated geothermal reservoirs that have been developed to date. One of these differences is the presence of hyper-dine brines containing up to 28% TDS (Total Dissolved Solids) and up to 0.2% NCG (Non-Condensible Gas). A simple material and energy balance model has been developed to study the e...

Microbial desalination cells (MDCs) hold great promise for drinking water production because of potential energy savings during the desalination process. In this study, we developed a continuously operated MDC--upflow microbial desalination cell (UMDC) for the purpose of salt removal. During the 4-month operation, the UMDC constantly removed salts and generated bio-electricity. At a hydraulic r...

 Aquaponics is a cultivation method that combines aquaculture and hydroponics which can produce two products, namely plants fish at time on relatively narrow land. The important thing in implementing aquaponics to maintain water quality so it remains the standard of products. Automatic control make easier for cultivators more efficiently. Therefore we need an aquaponic system focuses para...
The Colorado River is a principal source of water for 40 million people and farmlands in seven states the western US Republic Mexico. river has been under intense pressure from effects climate change anthropogenic activities associated with population growth leading to elevated total dissolved solid (TDS) suspended (TSS) concentrations. Elevated TDS- TSS-related issues basin have direct negativ...
Demanding public opinion for providing safe drinking water is now an increasing constant pressure on the authorities concerned to prevent the human health from contaminated drinking water. Hence latest techniques are employed to predict the critical parameters like, pH, chlorine, turbidity, TDS, and Electrical conductivity, in the distribution systems. In this study Radial Basis Function RBF mo...
The aim of the present study was to characterize the physical, biochemical and antioxidant properties of Algerian honey samples (n = 4). Physical parameters, such as pH, moisture content, electrical conductivity (EC), total dissolved solids (TDS), color intensity, total sugar and sucrose content were measured. Several biochemical and antioxidant tests were performed to determine the antioxidant...
