The use of filter soil is increasing for control of quality of stormwater runoff prior to infiltration or discharge. This study aimed to gain knowledge about treatment efficacy of filter soils at field scale. Percolate samples from swale-trench systems with filter soil based on agricultural till with/without limestone were monitored for 15 and 9 rain events respectively. Further, two curb exten...

Based on the developed neural-fuzzy control system for anaerobic hybrid reactor (AHR) in wastewater treatment and biogas production, the neural network with backpropagation algorithm for prediction of the variables pH, alkalinity (Alk) and total volatile acids (TVA) at present day time t was used as input data for the fuzzy logic to calculate the influent feed flow rate that was applied to cont...

The influent concentration has a great effect on nutrients removal efficiency in vertical subsurface flow constructed wetland systems, but treatment performance response to different C: N: P ratios in the influent are unclear at present. At the first growing seasons, the effects of the plants present or not, season, the different C: N: P ratio in influent condition and their interaction on trea...

Inflow and Infiltration (I/I) is extraneous water that enters a sewage treatment plant via groundwater infiltration or direct stormwater entry into sewers. This study is an attempt to quantify I/I impacts based on an assessment of influent and effluent data from twenty-four wastewater treatment plants (WWTPs) in Georgia with design capacities of 37,850 m/d (10-mgd) or greater. Twelve-months of ...

To understand wastewater quality transformations in the sewer system, a full-scale study focused on the characteristics of the influent wastewater in a middle-sized wastewater-treatment plant receiving only municipal sewage. The objective was to identify conditions in which prefermentation prior to the biological nutrient removal (BNR) process would be useful. Prefermentation aims at increasing...

This research aims at study of the effect of sulfide on operation of one of the aerobic biological treatment processes, activated sludge. For this purpose, two pilot plant units were designed and constructed. One of these units was run for wastewater sulfide contaminant (sample), and the other one was run for wastewater without sulfide contaminant (Reference). First of all, in a quantities stud...

one of the main disadvantages of anaerobic wastewater treatment at a low ph is the significantoperational cost due to the addition of necessary alkali. to reduce alkali supplement and thus the cost, thisstudy proposes a sequential multi-feed (sqmf) mode (distributed feeding) and effluent recycle (er) mode.experiments were conducted with a pilot-scale (2.5 m3) thermophilic (55°c) multi-staged up...
