Design Characteristics For Evaporation Ponds In Wyoming
ABSTRACT:
Information for the design of evaporation ponds in Wyoming has been developed. The suitability of various models for estimating evaporation and its variability was investigated while the spatial and temporal variabilities of net evaporation at seven locations were described. A routing procedure was developed to analyze the effects of uncertainty in net evaporation estimates on the probability of pond failure. Comparison of equations which estimate evaporation using climatological data showed that the equations vary greatly in their ability to define the variability of evaporation. The Kohler-Nordenson-Fox equation provided monthly and annual evaporation estimates having statistics resembling those of
measured pan data closer than any of seven other equations tested. The equation requires temperature, radiation, wind, and humidity data as inputs. The Kohler-Nordenson-Fox equation using climatic data extrapolated from nearby stations provided better definition of the variability of evaporation than did equations requiring only on-site temperature data. However, results indicate that extreme care must be taken in selecting the stations from which data will be extrapolated. Monthly and annual means, standard deviations, and highest and lowest evaporation and net evaporation values have been calculated for seven Wyoming stations. The year-to-year and spatial variation of evaporation and/or net evaporation in Wyoming was shown to be great enough to cause serious problems in defining rates for evaporation pond designs. Several factors were shown to exist which might produce uncertainties in any estimate of evaporation. The routing procedure was applied to analyze the effects of these uncertainties and variations. Results indicate that the liquid depth of an evaporation pond depends greatly on evaporation rates and maintenance of minimum liquid depths without pond overflow is very difficult.

Guidelines for Drinking-Water Quality
The primary purpose of the Guidelines for drinking-water quality is the protection of public health. The Guidelines provide the recommendations of the World Health Organization (WHO) for managing the risk from hazards that may compromise the safety of drinking-water. The recommendations should be
considered in the context of managing the risk from other sources of exposureto these hazards, such as waste, air, food and consumer products.

Design of Water Hammer Shock Absorber
Abstract:
In the piping system, water hammer or hydraulic shock is a major issue that engineers need to consider. Water hammer is a phenomenon that leads to shock waves in the fluid due to rapid closing and opening of the valve, which can affect pipes, valves and gauges in any water, gas, or oil applications due to the sudden transient event. It is there for every system that has a flow of fluid through pumping such as houses, hospitals, and influences major effectiveness in the power plant. It occurs when there is a pressure difference in the pipeline leading to a loud noise. Specifically, this project is aimed to design a pipeline system and develop solutions to reduce the water hammer using a shock absorber. The main idea of the design project is to design a water hammer system using a shock absorber in order to reduce the shock waves of the pipes.

Small Wastewater Treatment Works DPW Design Guidelines
This document’s purpose is to direct the design process for designing the best and most Appropriate wastewater process for effluent which is generated by small scale on site operations, Up to 100 m3/day such as police stations, border posts, DOJ etc. Larger plants are also addressed To some extent. In this manual, the best appropriate process for such small waste water treatment Plants has already been identified as the Rotating Biological Contactors (biodiscs) systems and Biological trickling filters (biofiters) for larger quantities. Consultants designing such plants for The DPW need to take cognizance of all the criteria set out herein and must ensure that apart from That the best available practices as regards such processes are incorporated into the design. The Designers of such plants are however still to consider other alternatives if the circumstances so Dictate.

Chapter 3. Activated Carbon Columns Plant Design
Maybe, the first question that we have to ask ourselves is related to the decision of an adsorprtion process using activated carbon for the removal of micro pollutants is efficient. The theory says that the adsorbability of an organic molecule increases with increasing molecular weight and decreasing solubility and polarity. This means that high molecular weight compounds with low solubility, such as most pesticides, are well adsorbed, so the first idea is plenty justified.
