Adinin Group of Companies has been involved in one of the largest remediation projects in Brunei, some of the details of the project are given below:
» Remediation of Sungai Bera Holding Basin «
Project Details
Location: Seria, Brunei Darussalam
Performance based “Turnkey” Project
disposal of sludges and liquid wastes from Oil Based Muds (Site consisted of 3 unlined holding basins covering an area of approx. 6 hectares (Northwest Basin, Northeast Basin, Main Channel).
Two basins (Northwest & Northeast) were formerly used for temporary OBMs), tank bottoms, etc.
The Main Channel Basin was used as a holding basin for wastewater effluent.
Total volumes of sludge & soil consists of:
Approx. 55,000 m3 of oily sludge in Basins & 10,000 m3 stored off-site.
Approx. 40,000 m3 of contaminated soil (underlying & surrounding the basins)
Project Scope of Work
Design & Engineering
Design & Engineering was completed primarily on-site, with support provided from Canadian partners on an as required basis.
Senior design engineers were relocated to Brunei for on-site design & engineering.
Full design and CAD facilities were set up at the site.
Design & Engineering was completed during the initial 3 months following project award.
Contamination Volume Surveys
Surveys were conducted to determine the volume of sludge and contaminated soil.
The surveys were completed on a 20 m grid throughout the basin areas.
Samples were collected for petroleum hydrocarbon analysis with elevations established using “total station” surveying equipment.
The data was inputted into computer models to determine the volume of sludge and soil to be excavated.
The models were also used to generate cross-sections and contour diagrams of the excavation limits.
Set Up & Commissioning
Essentially all new treatment equipment was procured for completion of this project.
The major treatment systems were mobilised from North America and Australia.
Set up and commission was completed by August 2000.
Floating Product Recovery & Treatment
The first phase of remediation encompassed recovering and treating the floating product deposited in the Main Channel in 1999.
A storage pond, complete with a High Density Polyethylene (HDPE) liner, was constructed for temporary storage of the product prior to treatment.
Pumping of the product from the Main Channel to the holding pond was completed in Spring 2000.
From the holding pond, the product was pumped to the “Oil Treatment System” (described in subsequent slides).
Sludge & Soil Excavation
Excavation of the basins is being conducted in 4 phases
Well point dewatering is required to facilitate sludge & soil excavation due to the shallow watertable.
The excavated material is transported to temporary stockpiling areas awaiting blending for feed preparation purposes.
All wastewater from dewatering, as well as runoff from the sludge/soil storage areas, is collected and treated through the Wastewater Treatment Plant.
Feed Preparation
A consistent feed improves operational performance of the LTTD Plant.
For feed preparation purposes, the sludge and soil is blended together to create a consistent feed, with a hydrocarbon content of approximately 10%.
Following feed preparation, the material is transferred to a designated storage area awaiting treatment.
7. LTTD Plant Operations
The sludge and contaminated soil is treated through the Low Temperature Thermal Desorption (LTTD) Plant.
8. Oil Treatment Operations
Two Systems are provided on-site as part of the oil treatment operations:
1. Liquid Sludge Pretreatment System.
2. Oil Treatment System
Oil treatment operations for this project are subcontracted to Macodril Sdn. Bhd.
9. Wastewater Treatment
The Wastewater Treatment Plant treats water from the following sources:
1. LTTD Plant & Oil Treatment System
2. Surface water runoff from work areas
3. Groundwater from the well point dewatering system
The treatment capacity of the plant is approximately 150 m3/hr and includes:
1. Coalescing Oil/Water Separator
2. Dissolved Air Flotation (DAF) Unit
3. Step Aerator
Treated water is discharged to the Sungai Bera river following confirmation of the treatment standards.
10. Laboratory Analysis
Laboratory analysis of sludge, soil and water samples is completed at SBRJV’s laboratory facility located at CIC in Kuala Belait, Brunei.
The lab includes 2 Gas Chromatographs (GCs) for analysis of TPH and BTEX.
Samples are submitted to the lab on a daily basis to confirm compliance with the established remediation criteria.
In addition, SBRJV operates an on-site field lab for BSW analysis of oil and Retort Oven analysis.
11. Backfilling & Site Restoration
Backfilling of the basins is initiated following excavation of sludge and contaminated soil.
Imported sand and treated ash is used for backfilling purposes.
The entire site will be re-vegetated following completion of excavation and backfilling operations.
