Total Suspended Matter (TSM) and the Standard Plate Count (SPC) of the sludge mixed liquor were ascertained. For the effluents, the Total Filtrable Residue (TFR), and the concentration of azaconazole (GLC-method) were measured. Radio-HPLC was used to monitor the presence of transformation products. The pH of the... 

Table 5 collects some characteristic parameters of the semi-continuous activated sludge test. The Total Suspended Matter of the mixed liquor (MLTSM) largely exceeded the target value of the test guideline [8 ] on day 0 and day 1 (7.74 and 7.02 ). This was corrected by removing additional settled sludge. From day 2 until day 17, the MLTSM remained in the range of 2.11 g/1 (day 2) to 1.47 g/1... 

An example of application of three-way PCA is a data set from the Venice lagoon. In it, 11 chemical variables (chlorophyll-a, total suspended matter, water transparency, fluorescence, turbidity, suspended solids, NH4, NOj", P, COD, and BOD5) have been measured monthly in 13 sampling sites (see Figure 5.5) during the period May 1987 to December 1990, for a total of 44 months. 

Total suspended matter found in the atmosphere as solid pieces or liquid droplets. Airborne particulates include windblown dust, emissions from industrial processes, smoke from the burning of wood and coal, and the exhaust of motor vehicles, airmass... 

When a liquid or solid substance is emitted to the air as particulate matter, its properties and effects may be changed. As a substance is broken up into smaller and smaller particles, more of its surface area is exposed to the air. Under these circumstances, the substance, whatever its chemical composition, tends to combine physically or chemically with other particles or gases in the atmosphere. The resulting combinations are frequently unpredictable. Very small aerosol particles (from 0.001 to 0.1 Im) can act as condensation nuclei to facilitate the condensation of water vapor, thus promoting the formation of fog and ground mist. Particles less than 2 or 3 [Lm in size (about half by weight of the particles suspended in urban air) can penetrate the mucous membrane and attract and convey harmful chemicals such as sulfur dioxide. In order to address the special concerns related to the effects of very fine, iuhalable particulates, EPA replaced its ambient air standards for total suspended particulates (TSP) with standards for particlute matter less than 10 [Lm in size (PM, ). 

Because there has been no recent analysis of the relationship between the concentration of total suspended particulate matter in the air of cities with populations of different sizes, we are forced to use data for the decade... 

Using the Code of Federal Regulations, list the current reference methods for measuring NO2, O3, SO2, CO, total suspended particulate matter, and lead. 

Air emissions should be monitored regularly for particulate matter and fluorides. Hydrocarbon emissions should be monitored annually on the anode plant and baking furnaces. Liquid effluents should be monitored weekly for pH, total suspended solids, fluoride, and aluminum and at least monthly for other parameters. Monitoring data should be analyzed and reviewed at regular intervals and compared with the operating standards so that any necessary corrective actions can be taken.

There is an additional Manual Monitoring Network, made up by 16 stations, committed to evaluate total particulate matter, PMIO (suspended particulate matter less than 10 /xm in diameter), sulfur dioxide and heavy... 

Regarding the total number of emissions to water, around 120 are included. About 25% of the waterborne emissions are covered by characterisation factors for human toxicity, and for ecotoxicity, the corresponding figure is 37% of the total number. The waterborne emissions from the material and disposal stage also include unspecific types like COD, TOC, VOC and suspended matter, for which information of the actual content is not available. Only 3.1% of the total emitted quantity (by weight) is covered by characterisation factors for human toxicity, and...

In the wastewater, an average ethoxylate chain length of 10 was found, with total A9PEOn concentrations of 500 pgL-1 [5]. Of these A9PEOn, 6-60% was sorbed onto suspended solids. One likely removal process of A9PEOn from the estuarine water column is therefore sedimentation of suspended matter. However, no sediments were analysed to test this hypothesis. 

Particulate matter is a complex emission that is classified as either suspended particulate matter, total suspended particulate matter, or simply, particulate matter. For human health purposes, the fraction of particulate matter that has been shown to contribute to respiratory diseases is termed PMio (i.e., particulate matter with sizes less than 10 tim). From a control standpoint, particulate matter can be characterized as follows (1) particle size distribution and (2) particulate matter concentration in the emission (mg/m ). On occasion, physical property descriptions may also be employed when there are specific control applications.

This is a separation process for removal of macromolecules of suspended matter from the waste by filtration through a semipermeable membrane under pressure. Total solids removal of 95% and above can be achieved.
