This article describes a statistical analysis of small water systems' turbidity data within the framework of a logic model for the USEPA's Performance-Based Training (PBT) program. The logic model shows the theoretical linkages between optimization training for small system operators; operator application of optimization techniques; improvements in plant filtration performance; and public healt...

An aluminum fractionation study was conducted for a surface reservoir water treatment to understand the performance of poly-aluminum-silicate-chloride (PASiC) in terms of the residual Al fractions as a function of initial pH. The coagulation performance expressed as turbidity and organic matter removal was established as supporting data. Some extra data were evaluated in terms of the residual A...

Many substances of plant origin are extracted for use in the primary treatment domestic wastewater. In most cases, they used as coagulating and flocculating agents derived from seeds, leaves, bark or sap, roots, fruits trees plants. this research, Cassia fistula seed was evaluated removal turbidity color wastewater a pumping station city Cartagena (Colombia). The optimal dose C. powder determin...

The subject of research was groundwater from Quaternary formations with high concentration of total iron, increased colour and turbidity, and an increased amount of organic substances and manganese. Successful purification of such water creates technological problems and is practically impossible to achieve by applying traditional groundwater treatment processes. One of the ways recommended for...

Moringa is a genus with many applications; some of these applications can be linked to their use in traditional medicine and as source nutrients, traditionally, species have been used for water purification. Many studies conducted assess the different One that extensively studied M. Oleifera because its wide geographical distribution. There are limited on peregrina due distribution, it native A...

background: today with population growing, surface water is one of the most important water resources used for domestic and industrial consumptions. in order to purify the surface water, coagulants materials are used. the purpose of this study was to assess the possibility of using poly aluminum chloride (pacl) in water refinery number 1 in city of orumieh and investigating its health effects. ...

It can be shown from bedform stability diagrams, that each turbidity current, regardless of whether its density is low or high, or whether its history is simple (e.g., surging flow) or complex (e.g., sustained flow), should pass through a final waning phase in which flow conditions are prone to bedform development. Yet, many thick deep-marine sandstones of supposed turbidity-current origin are ...

The aim of this work was the study of the combination of an inorganic pre-polymerized coagulant (PACl) with ferric species and polysilicic acid in various mixing order, Al/Fe/Si and OH/Al molar ratios, and two polymerization techniques for the production of a unique reagent representing a coagulant, more efficient than commercial PACl-18 and laboratory prepared PACllab for water or wastewater t...

Constructed wetland plays an important role in the removal of micro-polluted water pollutants urban sources. However, purification capacity and influencing factors constructed wetlands still need to be explored. This study monitored turbidity, ammonia nitrogen (NH3-N), dissolved oxygen (DO), chemical demand (COD) at inlet outlet Shijiuyang Wetland Jiaxing City from 2019 2021. The results showed...

In this study, the degree of goodness fit presented by San model is determined to calculate percentage removal flocculent particles, when initial turbidity in problem water low. For this, frequency analysis historical data that enters four drinking treatment plants located department Cundinamarca (Colombia) made, which show values range between 0.60 and 15.08 NTU (Nephelometric Turbidity Units)...
