Designing a Control Strategy to Automate a Solids Handling Process in a Municipal Wastewater Treatment Plant (WWTP) - (PPT)The Edmonton Gold Bar Wastewater Treatment Plant (WWTP) was first commissioned in 1956. The plant is large (serving a population of over 800,000), and many processes must...
4.1.2.4 The wastewater treatment plants in not important control water areas and not water conservation areas in some towns, should carry out Level III standard when they uses enhanced primary treatment process, according to the local economic condition and water pollution control requirements. However...

Toxaphene ranged from 7 to 410 parts per trillion (ppt), and BHC from 7 ppt to 1.0 part per billion (ppb). Samples of treated and untreated water showed that the purification process failed to remove toxaphene and BHC. Samples taken in the summer of 1960 from the stream system indicated ...
This again confirmed that the limit of the adaptive biodegradation properties of AS in such a composition of the biological purification process had been reached. Further elimination of residual pollutants can only be done by completing the biological water treatment module with other ones—membrane ...
Total circulated water was about 12 m3 h−1. Table 3. Process equipment and parameters for each step of process. Treatment of supernatant from the harvesting and dehydration stages is necessary since our target is to reuse the water for microalgae culture. Another issue is that the ...
The fast-firing cycle used in this investigation was selected to simulate an actual firing process used in the ceramic tile industry [25]. The following as-fired technological properties of the floor tile pieces have been determined in accordance with standardized procedures: linear shrinkage, water...
In the process of policy implementation, these cities should pay attention to improving the technical level of the relevant staff, introducing new technology for MSW classification, advocating multi-subject governance. Because the fourth type of "high-low" cities with low SE are at the decreasing ...
1. Introduction A wide range of organic wastes may be used, either directly or following appropriate treatment, in the biological and/or chemical reclamation of degraded areas [1]. For this purpose, municipal sewage sludge (MSS), which is predominantly sourced from wastew- ater treatment plants...
