A Treatise on Turbidity and TSS
When two distinct physical parameters are used interchangeably, an intimate understanding of both is in order to know when this is justifiable. Two such parameters are turbidity and total suspended solids. In many industries today the concentration of total suspended solids is of utmost importance to quality control and process optimization. However, the measurement most often employed is ...

Three lamella settlers were monitored over a period of 4 years. The main objective was to determine removal efficiencies for total suspended solids and associated pollutants. For this purpose a new sampling method based on large volume solid samplers was developed allowing a detailed analysis of solids. With regard to total suspended solids the average removal efficiency of the plants range ...

Impacts of Barrage Flushing and Flooding in Operations on Upstream Total Suspended Solids
This study looks into the impacts of Sarawak Barrage (located in Kuching City, State of Sarawak, Malaysia) flushing and flooding-in operations on upstream total suspended solids (TSS). Water samples were collected from three upstream stations on 17th, 18th and 19th of August 2000. During flushing, it was observed that TSS levels increased over a distance of 11 km upstream. Maximum TSS recorded ...

Constructed wetlands for combined sewer overflow treatment in a Mediterranean country, Portugal
The use of constructed wetlands as a valuable and attractive method for combined sewer overflow (CSO) treatment has been demonstrated in several studies. In Portugal, a Mediterranean country having usually a long dry period, there are still no applications of this technology. The purpose of this research is to gather information and know-how required for the design and management of this type ...

Optimal design activated sludge process by means of multi-objective optimization: case study in Benchmark Simulation Model 1 (BSM1)
Optimal design of activated sludge process (ASP) using multi-objective optimization was studied, and a benchmark process in Benchmark Simulation Model 1 (BSM1) was taken as a target process. The objectives of the study were to achieve four indexes of percentage of effluent violation (PEV), overall cost index (OCI), total volume and total suspended solids, making up four cases for comparative ...

Pollution of surface runoff from the territory of Brest, Belarus
The assessment of the influence of urban surface runoff on the quality of river water in the city of Brest was made. Surface runoff was studied in two phases (winter and summer) for the following parameters: pH, total suspended solids (TSS), concentration of chloride, nitrate, phosphate and ammonium ions, total oils. The results show that urban surface runoff is an important source of pollution ...

Development of a down-flow hanging sponge reactor for the treatment of low strength sewage
The process performance of a down-flow hanging sponge (DHS) reactor for treating low strength sewage (biochemical oxygen demand (BOD) 20–50 mg/L) was investigated in Bangkok, Thailand. The hydraulic retention time (HRT) was set at 4 h during the start-up period and was reduced to 1.5 h in a stepwise manner. Throughout the 300-day operational period, the DHS reactor shows high performance ...

Ph and total solids control for concrete producers
Fortrans Inc. manufactures a self-contained pH control and monitoring system that uses CO2 gas to neutralize high pH process water and lower total suspended solids in process water produced at ready mixed concrete plants. The Model 5000S pH Control and Monitoring System offers precise pH control, monitoring of pH and lowers “Total Suspended Solids” of process water contained in pits, ...

The development of a novel approach for assessment of the first flush in urban stormwater discharges
The management of stormwater pollution has placed particular emphasis on the first flush phenomenon. However, definition and current methods of analyses of the phenomena contain serious limitations, the most important being their inability to capture a possible impact of the event size (total event volume) on the first flush. This paper presents the development of a novel approach in defining and ...

Relationship between turbidity and total suspended solids concentration within a combined sewer system
This article confirms the existence of a strong linear relationship between turbidity and total suspended solids (TSS) concentration. However, the slope of this relation varies between dry and wet weather conditions, as well as between sites. The effect of this variability on estimating the instantaneous wet weather TSS concentration is assessed on the basis of the size of the calibration dataset ...

Column studies to determine mercury settling in road runoff
A study was performed using a settling column to remove mercury (Hg) from road runoff. The emphasis was placed on the relationship between Hg removal and critical settling velocities, as well as the distribution of total suspended solids (TSS). The impact of rainfall characteristics and temperature on Hg removal was also discussed. Results indicated that Hg removal was significant within the ...

Modelling of suspended sediment in a weir reach using EFDC model
Construction of hydraulic structures often leads to alteration of river dynamics and water quality. Suspended solids entering the upstream of the weir cause adverse effects to the hydroecological system and, therefore, it is necessary to build a modelling system to predict the changes in the river characteristics for proper water quality management. In this study, the discharges and total ...

Pizza Dough
A facility located in California manufactures pizza shells and the resultant wastewater was extremely high in total suspended solids (TSS) and biochemical oxygen demand (BOD). The company had reached its maximum discharge allowance, but wanted to expand their capacity. They were paying enormous surcharges and to expand, as they wanted, would have cost them an additional huge amount in surcharges ...

Ceramic Polishing
A company was using several chemistries to remove the total suspended solids (TSS) from their wastewater. The facility manufactures stainless steel surgical instruments. The wastewater is generated from the polishing/deburring of these instruments using an aluminum/ceramic polishing media. The jar tests shown are from the addition of the Floccin-H to the wastewater and moderate mixing. The TSS ...

Valorization of the Vicia faba mucilage on textile wastewater treatment as a bio-flocculant: process development and optimization using response surface methodology (RSM)
The Vicia faba membranes are an abundant and a low cost product. In the present research paper, the extracted Vicia faba mucilage was tested as an eco-friendly flocculant for textile wastewater treatment. Its performance as flocculant, in decolorization, chemical oxygen demand (COD) removal and the concentration of total suspended solids was checked. The natural extracted product was ...

Uncertainties of spectral in-situ measurements in wastewater using different calibration approaches
Abstract: Three calibration methods were applied to UV/VIS spectra recorded in the influent of six wastewater treatment plants (WWTPs) to measure total COD (CODtot), filtered COD (CODfil), nitrate and nitrite nitrogen (NOx-N) and total suspended solids (TSS). It could be shown that a calibration of the sensor using data sets from four Swiss WWTPs leads to an improvement of the precision in ...

Analysis of hydrocyclone behaviors in the separation of particulates from highway rainfall runoff
In this study, the separation behaviors of particles in highway rainfall runoff using a Ø7.5 cm hydrocyclone were examined. The volume fraction and the total suspended solids concentrations in the overflow and underflow from the hydrocyclone were analyzed. The results indicated that the overflow volume fraction increased with increasing operational pressure, but decreased with decreasing ratio of ...

Modelling the influence of total suspended solids on E. coli removal in river water
Following sewer overflows, fecal indicator bacteria enter surface waters and may experience different lysis or growth processes. A 1D mathematical model was developed to predict total suspended solids (TSS) and Escherichia coli concentrations based on field measurements in a large-scale flume system simulating a combined sewer overflow. The removal mechanisms of natural inactivation, UV ...
