Case Study 1: Remediation Water Treatment Project


Project Overview:

A manufacturing facility had been operating for several decades, resulting in soil and groundwater contamination with various pollutants, including heavy metals and organic compounds. To mitigate the environmental impact, a remediation water treatment project was initiated to treat contaminated groundwater before it entered nearby water bodies.


  • Remove or Reduce Contaminants to Acceptable Levels.

  • Prevent Further Migration of Contaminants Into the Surrounding Environment.

  • Ensure Compliance With Local Environmental Regulations and Standards.

  • Protect the Health and Safety of Nearby Communities and Ecosystems.

Project Implementation:

STEP 1: 'Site Characterization & Assessment' The initial phase involved conducting a comprehensive site investigation to determine the extent and types of contamination present. This included collecting soil and groundwater samples, analyzing them in a laboratory and creating a detailed contamination map.

STEP 2: 'Design & Engineering' Based on the site assessment findings, a remediation water treatment system was designed. The system consisted of multiple treatment units, each targeting specific contaminants. The treatment train included processes such as, filtration, chemical precipitation, activated carbon adsorption and oxidation.

STEP 3: 'Construction & Installation' After finalizing the design, the construction phase began. The treatment system components, including pumps, tanks, filters and monitoring equipment, were all installed onsite. The infrastructure was built to handle the required flow rates and meet the anticipated treatment goals.

STEP 4: 'Operation & Monitoring' Once the construction was completed, the treatment system was commissioned and began operations. Trained personnel operated and monitored the system regularly to ensure optimal performance. Monitoring included measuring influent and effluent concentrations, flow rates and system parameters to assess treatment efficiency.

STEP 5: 'Performance Evaluation & Adjustments' The project team conducted ongoing performance evaluations to determine the effectiveness of the treatment system. If necessary, adjustments were made to optimize the treatment process based on the collected data and regulatory requirements.

Results and Benefits:

[ Contaminant Removal ] The remediation water treatment system successfully reduced the concentrations of contaminants to acceptable levels, meeting regulatory standards.

[ Environmental Protection ] By treating the contaminated groundwater, the project prevented further migration of pollutants into nearby water bodies, safeguarding the surrounding environment.

[ Compliance ] The treated water met local environmental regulations and standards, ensuring the facility's compliance with applicable laws.

[ Community Safety ] The project improved the safety of nearby communities by reducing the risk of exposure to hazardous substances.

[ Long-Term Sustainability ] The treatment system was designed to be efficient and cost-effective, providing a sustainable solution for long-term operation and maintenance.

In conclusion, the remediation water treatment project effectively addressed the contamination issues at the manufacturing facility. By implementing a comprehensive treatment system, the project achieved the objectives of contaminant removal, environmental protection, compliance and community safety. This case study demonstrates the successful application of water treatment technologies in remediating contaminated sites.


Case Study 2: Water Treatment in Gas and Oil Industry


Project Overview:

Client, an international gas and oil exploration and production company, operates in a region characterized by challenging environmental conditions and stringent water quality standards. The company faced several water-related challenges in its operations, including high levels of oil and suspended solids in produced water, high salinity and strict regulations for water disposal.


Oil & Suspended Solids Removal - The produced water contained significant amounts of oil and suspended solids, which needed to be effectively separated and removed to comply with environmental regulations and protect downstream equipment.

Salinity Management - The high salinity of the produced water posed challenges for reuse or safe disposal. Reducing the salinity to acceptable levels was necessary to protect equipment and prevent scaling and corrosion.

Compliance With Environmental Regulations - The region had stringent regulations regarding water quality and disposal. The company needed to ensure that their water treatment processes met these standards and minimized the environmental impact of their operations.

Project Implementation:

STEP 1: 'Primary Separation' To remove large oil droplets and suspended solids, a primary separation system was implemented. This system utilized gravity-based separation techniques, such as API separators and hydrocyclones, to achieve effective separation.

STEP 2: 'Secondary Treatment' After primary separation, the water underwent secondary treatment processes to further remove residual oil, dissolved hydrocarbons, and fine suspended solids. Technologies such as dissolved air flotation (DAF), multimedia filtration, and activated carbon adsorption were employed. To polish water further a large multi media filtration unit was installed to ensure potential debris that could possibly foul the RO unit were removed. The unit designed allowed the RO unit to operate at full potential while reducing any harm caused from dirty water and contaminants.

STEP 3: 'Desalination' To manage the high salinity of the produced water, a desalination unit was installed. Reverse osmosis (RO) membranes were utilized to remove dissolved salts and reduce the water's salinity to acceptable levels for reuse or safe disposal.

STEP 4: 'Advanced Monitoring & Control' The water treatment system was equipped with advanced monitoring and control technologies to optimize performance and ensure compliance with environmental regulations. Real-time monitoring of key parameters such as oil concentration, pH, turbidity, and salinity allowed for proactive adjustments and troubleshooting.

Results and Benefits:

By implementing these water treatment solutions, The client achieved several notable results and benefits

[ Compliance With Regulations ] The treated water met the stringent water quality standards set by local regulatory authorities, ensuring environmental compliance and avoiding penalties.

[ Equipment Protection ] The removal of oil, suspended solids and dissolved salts minimized equipment fouling, corrosion and scaling; enhancing the operational efficiency and lifespan of the equipment.

[ Water Reuse ] The treated water, with reduced salinity and contaminants, was suitable for various non-potable uses within the company's operations, reducing freshwater consumption and conserving resources.

[ Cost Savings ] The implementation of an efficient water treatment system resulted in cost savings by reducing the need for freshwater intake, minimizing wastewater disposal costs, and optimizing operational efficiency.

In conclusion, this case study highlights the importance of effective water treatment in the gas and oil industry, by addressing the challenges of oil and solids removal, salinity management and regulatory compliance. Multi-media filtration is a valuable secondary treatment process in water treatment systems within the gas and oil industry. By effectively removing suspended solids and fine particles, multi-media filtration enhances water quality, protects downstream equipment and contributes to the overall efficiency and sustainability of oil and gas operations.
