Process Safety Management Practices in Pakistan Globally industries have successfully implemented Process Safety Management (PSM) systems which have enormously reduced incident magnitude, their dreadful repercussions, and have proven organisational stability thereby maximizing profit margins. Due to limited data access, lack of incident and near-miss reporting & recording trend, lack of understanding and implementation of process safety management, petroleum refining sector as one of the most prone-to-incident industries globally was selected as a base case to evaluate process safety management practices in Pakistan. |

Treatment of Refinery Wastewater using Vertical Flow Constructed Wetlands Pilot scale constructed wetlands were used to treat refinery wastewater. The experimental set up consisted of four vertical flow constructed wetlands (CW) with different plants and media. CW 1 was planted with common reed (Phragmites), CW 2 was planted with phragmites plus additional layer of sludge over the media, CW 3 was planted with cattail (Typha) plus additional layer of sludge over the media while CW 4 was planted with Typha. Experiment was conducted at Karachi (Pakistan) with a warm humid summer (38ºC) and a normal cold winter (10ºC). After acclimatization period, wastewater from a local refinery was added manually to maintain a hydraulic loading rate of 85 mm/d. The four CW removed all monitored pollutants with good removal efficiencies during the initial monitoring period: turbidity (91%, 72%, 96%, 95%); suspended solids (87%, 86%, 86%, 73%), oil and grease (77%, 80%, 60%, 83%), COD (57%; 47%; 53%, 72%); BOD (37%, 49%, 33%, 36%); sulphate (62%, 77%, 85%, 76%), chloride (96%, 95%, 98%, 98%) and total phenol (68%, 98%, 98%, 97%). Overall CW 4 showed the best performance in removing pollutants. For phenol removal, CW 2 and CW 3 performed better than CW 1 and CW 4. With regard to type of plant species, wetlands with Typha performed better than those planted with Phragmites. |

Treatment of Produced Water from a Gas Field using Free Water Surface Wetland System A pilot scale free water surface (FWS) wetland system was built at a gas field in Sindh province of Pakistan. The pilot system consisted of two treatment cells, cell 1 was planted with Phragmites while cell 2 with Typha. Initial monitoring of the wetlands for removal of hydrocarbons started in July 2013. The average influent BTEX values were as follows: benzene (0.9 mg/L), toulene (0.1 mg/L), ethyl benzene (0.2 mg/L), m-xylene (1 mg/L) and o-xylene (0.1 mg/L).The FWS wetland system removed all monitored contaminants with good removal efficiencies during the 6 months monitoring period: benzene (89.1%), toulene (89%), ethyl benzene (97%), m-xylene (88.1%) and o-xylene (80.2%). |

Waste materials as substrates in vertical flow constructed wetlands treating domestic wastewater Vertical flow constructed wetlands (VFCW) are considered to be one of the most efficient type of wetlands and require a lesser footprint in comparison to other wetland types. Substrate is an important component of wetland. We used the common gravel (VFCW 1) and three waste materials: concrete (VFCW 2), slag concrete (VFCW 3) and coconut husk (VFCW 4) as substrates in experimental wetlands. All four experimental wetlands have been constructed in uPVC pipes, diameter and height of each VFCW was 89 mm and 1000 mm, respectively. A 15 mm dia perforated pipe that penetrates to the wetland bottom was installed in each wetland for passive aeration. Canna indica, an ornamental plant was planted in all four wetlands. Pre-treated wastewater from a wastewater treatment plant was added manually to all VFCW. The maximum plant height observed was 78.7 cm in VFCW 1 while minimum plant height observed was 53.3 cm in VFCW 3. The four VFCW removed all monitored contaminants with good removal efficiencies during the 8 months monitoring period: suspended solids (79%, 74%, 74%, 54%); BOD (54%, 42%, 42%, 2%); COD (54%; 47%; 44%, 34%); ammonia-nitrogen (54%, 46%, 38%, 38%), ortho-phosphate (67%, 61%, 64%, 53%); and fecal coliforms (55%, 40%, 14%, 52%). DO levels increased for VFCW 1 and 4 and nitrate levels increased in all wetlands confirming the nitrification process. For the various waste materials used following were our observations: VFCW 2 performed the best for organic matter and ammonia-nitrogen removal while VFCW 3 outperformed others for phosphorus removal and VFCW 4 had the highest percentage of fecal coliforms removal. |

Green Wall for Grey Water Treatment and Recycling At NEDUET Campus The purpose of this project was to design, construct and test a Green Wall as a demonstration project at NEDUET campus. The system was developed using uPVC pipe (4 inches diameter and 15 feet long). The pipes were filled with waste concrete (coarse aggregates) to support the vegetation. More than ten species of ornamental plants including those that have energy potential were planted in the system. The system was monitored for various water quality parameters including pH, turbidity, suspended solids, BOD, COD, nutrients, total and fecal coliforms. The developed system successfully treated the grey water generated from the faculty washrooms of the civil engineering department. The results demonstrate that the system can provide multiple benefits including adding aesthetical feature to the building, improving air quality, saving energy cost by cooling effect and treating wastewater that can be reused for irrigation purposes. |

Development of Urban Forest at NED University of Engineering and Technology The Urban Forest project was initiated in collaboration with The Institution of Engineers, Pakistan (IEP), Karachi Center. Students of third year Urban Engineering were also involved in this project. 90 trees, 14 tree species were planted in an area 28 m2 (300 ft2). The urban forests grow 10 times faster than conventional plantation; they are 100 times more bio-diverse and have 30 times more green surface area. The entire development process is 100% organic with no addition of chemicals and pesticides. They also have 30 times more CO2 absorption capacity and 30 times better noise, and dust reduction ability, than the conventional tree plantation. |
