Although federal drinking water regulations determine the quality of potable water, many specifics influence how each utility chooses to treatment water. Some of the specifics include source water quality, storage capacity, existing unit process, and space. An overview of the US recreational and drinking water regulations were discussed in context of cyanobacterial toxin removal and inactivatio...

Background: The objective of this work was to decontaminate synthetic sewage from fouracid blue (BRL) dye, with characteristics similar those the textile industry, determine correlation between flow rate, permeability and removal hexavalent chromium (Cr+ 6), Cupper (Cu), chemical oxygen demand COD color using Paradise Muse filter bed. Methods...

in this experiment, a total of 128 hy-line w36 hens at 63 weeks of age were used. the hens were put at random into 4 treatment groups (4 replicates and 32 hens per treatment) and were fed four different diets: three diets with different levels of spirulina (1.5, 2.0 and 2.5%) and one control group based on wheat and soybean meal. all birds were housed in commercial cages, had ad libitum access ...

the effluent quality of a sewage treatment plant using activated sludge process and finally secondary treatment depends on the flocculation efficiency and settling of the flocs. the survey of various treatment processes in water and wastewater treatment shows that temperature and ph are the important factors affecting efficiency of flocculation and settling properties. this study was performed ...

the aim of this study was to evaluate the ability of microalgae spirulina platensis and chlorella vulgaris to remove nitrate and phosphate in aqueous solutions. spirulina platensis and chlorella vulgar is microalgae was collected in 1000 ml of municipal water and kno3, k2hpo4 was added as sources of nitrate and phosphate in three different concentrations (0.25, 0.35 and 0.45g/l). during the gro...

Fluorescence excitation-emission matrix (EEM) spectroscopy coupled with parallel factor analysis (PARAFAC) is an established tool of organic matter fingerprinting in aqueous systems. Recently, EEMPARAFAC has been successfully applied in drinking water treatment for simple, rapid, and sensitive evaluation of organic matter removal during different treatment processes. This review describes some ...

Advanced treatment of biologically processed palm oil mill effluent (BIOTPOME), which possesses a potential danger to the water sources is required meet Malaysian discharge standard, as BIOTPOME contains high level chemical oxygen demand (COD), suspended solids and grease even after going through conventional process. The significant but insufficient efficiency ponding system in Malaysia urged ...

The United States Environmental Protection Agency Contaminant Candidate List 3 lists strontium as a contaminant for potential regulatory consideration in drinking water. Very limited data is available on strontium removal from drinking water and as a result, there is an immediate need for treatment information. The objective of this work is to evaluate the effectiveness of coagulation/filtratio...

SUVA (equivalent to UV254/DOC) value in raw water is a precursor for the formation of trihalomethane during chlorination at a water treatment plant. This study collected rapidly filtered water from an advanced water treatment plant for use in experiments on raw water. The removal rate of treating the trihalomethanes formation potential (THMFP) was conducted by using a biological activated carbo...
