Objective Our MCE analytics platform uses existing chemical tank level data for chemical management and monitoring on water and wastewater sites. By monitoring the rates of change in tank levels, we automatically work out if tanks are emptying or being filled. So, we can calculate chemical consumption and applied dose rates using existing telemetry or SCADA data. This is up and ...

Whether its for municipalities, industries, or commercial facilities, water and wastewater treatment regulations are consistently changing, as new pollutants and contaminants are discovered and researched. For example, pathogenic microorganisms have been studied for their effects on human health, their points of origin and reach, and the ways they can be dealt with for well over a century. On top ...

Certain types of samples, such as those containing detergent, may form emulsions when doing an oil in water extraction into a solvent. The boundary between the solvent and the sample will have an emulsion layer that has a cloudy or milky appearance as shown in this photo. According to U.S. EPA Method 1664, “if the emulsion is greater than one-third the volume of the solvent layer, the ...

Pharmaceuticals and their metabolites are detected on an increasing scale in the aquatic environment. The pharmaceuticals (such as drugs) mostly get into the surface and drinking water through the excretions of humans and animals; however, the wastewater of pharmaceutical production facilities can also be contaminated with active ingredients. The production of pharmaceuticals takes place in two ...

In many local authorities, the limit for lipophilic substances has been tightened from 250 mg/l to 100 mg/l. In such cases, a grease separator is not sufficient to ensure reliable adherence to this limit value. Plant description The kitchen wastewater of the canteen is discharged via the kitchen's floor channels, and through the wastewater inlet to a curved hydro sieve, ...

Access to clean water is a basic requirement for effective production. In Brazil, however, many regions suffer from acute water shortages. Some urban centres where large numbers of industrial enterprises have moved in, such as São Paulo, Rio de Janeiro or Belo Horizonte, are facing the worst water crisis in over 84 years, as Brazil's environment minister, Izabella Teixeira, explained in ...

BIOPETROL Rostock GmbH is owned by the Swiss BIOPETROL INDUSTRIES AG in Zug, and operates a bio-diesel plant in Rostock with an output of 150,000 t/a of bio-diesel and 24,000 t/a of crude glycerine. The emulsion-containing wastewater created during operation was disposed of externally. A more extensive wastewater treatment plant was required to facilitate the discharge of the wastewater into the ...

Abstract : The primary objective of this project was to evaluate six Toxkits and the IQ Toxicity TestsTM, for suitability in the role of screening of whole effluents in DTA required by Resource Consents. As an extension, their role as \'up the pipe\' toxicity identification tests were also evaluated. Screening tests must be cost effective (so that regular testing may be performed), ...

Abstract : The chemical composition and toxicity of five phenolic wastewaters samples collected from the Kohlta-Järve (Estonia) oil-shale industry region were analysed. The total phenolic contents (HPLC data) of these samples ranged from 0.7 mg/l to 195 mg/l. A total of 11 phenol (up to 84 mg/l) and p-cresol (up to 74 mg/l). Artificial phenolic mixtures were also composed, to mimic the ...

Abstract :The review first addresses the major bottleneck of conventional toxicity tests with invertebrates, namely the need for continuous culturing and/or maintenance of stocks of live test-organisms. Subsequently the history of the development and the validation of the first cyst-based microbiotests are outlined. Details are given of the large intercalibration exercises organized concurrently ...

Abstract : The toxicity of surface waters (Vistula river in Warsaw) and of raw and treated wastewaters (treatment plants in Grodzisk Mazowiecki and in Piaseczno) has been measured at 2 occasions with 4 Toxkit microbiotests : the Algaltoxkit F™, the Daphtoxkit F™ pulex, the Thamnotoxkit F™ and the Protoxkit F™. Although the Vistula river is classified as being highly ...

Abstract : In this study a comparative chemical and toxicological analysis of 8 phenolic river water and wastewater samples originating from the Kohtla-Järve oil shale industry region (north-western part of Estonia) was made. The total phenolic content of the samples ranged from 0.01 to 195 mg/l. For 5 wastewaters the corresponding synthetic phenolic analogues were prepared. A battery of ...

Abstract : Wastewaters from different pulp-making processes contain various organic and inorganic compounds : wood-derived, process chemicals and compounds generated during the reactions between the chemicals and raw materials. Carbohydrates and lignin-derived compounds constitute the main groups of components that cause oxygen demand in wastewater (COD), but they have rather low ...

Abstract : Microbiotests are a useful tool in acute toxicity investigations for pre-screening and screening of chemicals and wastes; tests based on enzymatic activity may be useful as a signal for chronic toxicity. The composition of a battery of microbiotests is function of the problem(s) under consideration. A battery of microbioassays should in principle be composed of ...
