  • How & Why We Measure Suspended Solids

    In case you weren’t sure, Suspended Solids is simply a density measurement used to describe exactly how much waste sludge and particles are in the water, and is measured in milligrams per litre (mg/l), grams per litre (g/l) or percentage solid (%). 1000mg/l = 1g/l = 0.1%. It is used to calculate the amount of material, or load, in a wastewater or industrial system. Suspended Solids ...

  • 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 ...

  • Remote sensing of suspended solids concentration in a reservoir with frequent wildland fires on its watershed

    Wildland fire is an important disturbance factor that can cause severe ecological and watershed damage. Depending on fire severity and watershed extension, reservoir suspended solids concentration (SSC), which arrives through river load, is expected to increase. Satellite remote sensing is an alternative technique to measure SSC in a reservoir. In this paper we evaluate the applicability of ...

  • Treatment of suspended solids and heavy metals from urban stormwater runoff by a tree box filter

    Particulates, inorganic and toxic constituents are the most common pollutants associated with urban stormwater runoff. Heavy metals such as chromium, nickel, copper, zinc, cadmium and lead are found to be in high concentration on paved roads or parking lots due to vehicle emissions. In order to control the rapid increase of pollutant loads in stormwater runoff, the Korean Ministry of Environment ...

  • Complete solids retention activated sludge process

    In a slaughterhouse's full-scale extended aeration activated sludge wastewater treatment plant (WWTP), operating under complete solids retention time, the evolution of mixed liquor suspended solids (MLSS) and mixed liquor volatile suspended solids (MLVSS) concentration, food to micro-organisms ratio (F/M) and substrate utilization rate (SUR) were studied for over a year. Biomass growth phases ...

  • Total Dissolved Solids (TDS) Measurement

    Definition Total Dissolved Solids (TDS) is a measure of the sum of all inorganic and organic substances in a liquid in molecular, ionized or micro-granular colloidal suspended form. The solids must be small enough to survive filtration through a sieve the size of two micrometer.  TDS solids are normally found in all freshwater systems. Major applications of TDS are: at low levels the ...

  • Sure, We Have Lots of Bioreactor Solids… But How Many are Active?

     ABSTRACT Biological wastewater treatment processes harness the ability of microorganisms to break down and assimilate organic compounds that, if left untreated, cause detriment to the environment. Although this process occurs naturally, engineered systems are used to accelerate the process by optimizing bioreactor conditions to promote higher-than-typical biomass concentrations, thus ...

  • Surfactant-assisted oil-in-water monitoring

    A variety of common surfactants have been used to reduce fouling and enhance the performance of fluorescence-based oil-in-water monitors. Among the most effective are the alcohol ethoxylates with HLB values close to 12. Examples are SurfonicTM L24-9 (Hunstman, USA, HLB 13) and TergitolTM 15-S-7 (HLB 12.1). These surfactants readily convert heterogeneous oil/water mixtures into homogeneous, ...

  • Separation of solids and disinfection for agronomical use of the effluent from a UASB reactor

    The present work addresses the preparation of the effluent from a full-scale upflow anaerobic sludge blanket (UASB) reactor for drip irrigation of orange crops. The pilot plant included a lamella plate clarifier followed by a geo-textile blanket filter and a UV disinfection reactor. The clarifier operated with a surface load of 115 m3m−2d−1, whereas the filter ...

  • Anaerobic digestion of waste biomass from the production of L-cystine in suspended-growth bioreactors

    Waste biomass from the industrial production of the amino acid L-cystine contains above-average concentrations of organic pollutants and significant concentrations of nitrogen and sulfur. The specific biogas production (SBP) of waste biomass was monitored in parallel suspended-growth laboratory anaerobic bioreactors. After severe inhibition was observed, three different procedures were applied ...

  • Innovative monitoring of combined sewer overflow (CSO) quality in the Liguori catchnment (Cosenza, Italy)

    Estimates of urban wet-weather flow pollutant loads are required to assess their impact on receiving waters and optimize wastewater treatment plant (WWTP) and combined sewer overflow (CSO) operations. In particular, a quantitative characterization of flow quality by means of fairly accurate monitoring is required for developing a rational planning approach and preferential treatment strategies. ...
