in this research the operation of fixed activated sludge system for treatment of wastewater containing heavy metal compounds, by use of fas pilot ,a plaxy glass tank with three section; these section are downward-flow aerated reactor, upward-flow aerated reactor and gravity sediment unit, length and width and height of each part was respectively 15.7cm, 31.5cm , 51.5 cm and feeding with the syn...

Aerobic granular sludge (AGS) with oversized diameter commonly affects its stability and pollutant removal. In order to effectively restrict the particle size of AGS, a sequencing batch reactor (SBR) spiny aeration device was put forward. A conventional SBR (R1) an (R2) treating tannery wastewater were compared in laboratory. The result indicates that from R2 smaller than R1 granulation. spines...

Recently, several swine farmers are trying to install a “Liquid Manure Pit Recharge System (LMPRS)” reduce odors, but many suffering from lack of related information. This research was carried out provide information pig who want LMPRS through field surveys the applied farmers, investigating characteristics installation and operation, classifying types by process. The survey five farms found co...

The increasing demand for 3D geospatial data is driving the development of new products. Laser scanners are becoming more mobile, affordable, and user-friendly. With increased number systems service providers on market, scope mobile laser scanning (MLS) applications has expanded dramatically in recent years. However, quality control measures not keeping pace with flood data. Evaluating MLS surv...

This work was aimed at identifying microbials and determining the biokinetic parameters for bio-decontamination of oilfield produced water. An extant physical treatment unit water re-engineered retrofit with a discontinuous aerobic bioreactor (Bio-Unit) system. The Bio-Unit operated in fill-and-draw sequence rates total organic carbon (TOC) removal biomass growth were monitored. isolated microb...

The present investigation was carried out to assess the operation of a pilot-scale submerged membrane bioreactor (SMBR) for treatment reactive dye and textile wastewater. SMBR model conducted by using polyethersulfone (PES) hollow fibre with continuous flow mode at different HRTs 8, 6 4 h, 90 days. During entire operation, average permeate flux, TMP, F/M ratio OLR found be 19 (L/m²/h), 2.6 (psi...
