Remediation - Total Chemical Management

????????????? Based on the requirements for the project, USP developed the following total chemical management program to meet project schedules and budget objectives: Site Analysis and Hazards Review USP engineering personnel worked closely with the remediation contractor to evaluate and plan for the specific hazards of the project site. Equipment was selected to ensure chemical containment site security provided additional public protection. A restricted-flow water source was available which required USP to provide a water storage tank for emergency response and to support product dilution requirements. Chemical and Logistics Management USP worked closely with the remediation contractor to ensure that all equipment and chemicals were delivered to the project site in a safe and timely manner. Hydrochloric Acid 110 gallons of 31% HCl Ferrous Sulfate 5,500 lbs of FeSO4 heptahydrate Hydrogen Peroxide 85,500 gallons of 17.5% H2O2 for primary treatment and 1,000 gallons of 8% for conditioning Sodium Persulfate 4,000 lbs of Na2S2O8 System Engineering and Equipment Design ?USP engineered an equipment program with multiple chemical storage and dosing systems designed and sized specifically for the project. This equipment program was designed according to strict engineering and chemical industry standards. The program focused on providing safe, reliable and cost-effective equipment solutions utilizing field-tested modular components for operational reliability, improved performance and simplified installation and startup. PENNSYLVANIA ISCO PROJECT - Total Chemical Management Program Remediation Case Study ??????????????? A remediation company was contracted to perform a cleanup of an abandoned gas station in south central Pennsylvania. The consulting engineer and the remediation contractor selected a treatment program utilizing In-Situ Chemical Oxidation (ISCO) as the preferred treatment technology. Due to the magnitude of the contamination and the widespread nature of the groundwater contamination, significant quantities of chemical (hydrochloric acid, ferrous sulfate, hydrogen peroxide, and sodium persulfate) and equipment were required to execute the site remediation. The scope and structure of the project required that a high volume of multiple chemicals be mobilized quickly which created a significant operational and cost challenge for the contractor. US Peroxide (USP) developed a Total Chemical Management Program to efficiently, and cost-effectively, execute the project.

We have been serving the water, wastewater and remediation markets for over 15 years and have offices and field service locations throughout North America. Our consultative approach to problem solving includes application assessment, technology selection (which may include lab scale testing, if necessary) and development of a tailored treatment approach. Our full-service programs successfully integrate storage and dosing equipment systems, chemical supply, inventory and logistics management, and ongoing field and technical support. This approach provides cost-effective “hands-off” solutions to our customers. USP also can provide access to experienced application partners for a turn-key program encompassing engineering, site characterization and technology selection, program implementation, execution and report generation. Getting Started We look forward to supporting your rapid response needs, whatever the scale of your chemical management requirements. To obtain a streamlined Rapid Response solution tailored to your specific project, just give us a call. Equipment Supply ? Hydrochloric acid was provided in 55-gallon drums and pumped using properly-designed drum pumps. Ferrous sulfate was injected as a liquid. At many sites the dry product is mixed into solution by hand, but with over 2.5 tons of dry product required, there were considerable concerns about the safety of the field personnel. As an alternative, USP developed a plan to provide an on-site storage and containment system to receive, store, and deliver the chemical in pre-mixed liquid form resulting in increased application efficiency and reduced overall costs. Through a modular on-site dilution system, USP was able to receive and store hydrogen peroxide at a 50% concentration, dilute to a custom 8% solution for initial conditioning, and to 17.5% for full-scale operation. The 50% H2O2 was delivered to the site in a 5,500 gallon bottom-discharge Isotainer specifically designed for H2O2 service. The Isotainer was then refilled with full tanker truck deliveries of 50% solution. USP provided a series of double and single wall HDPE tanks for dilution water and dilute H2O2 storage. The onsite dilution system and the ability to take full tanker truck deliveries reduced the hydrogen peroxide costs by over 50%. Chemical Dosing Systems: USP provided modular chemical dosing systems to feed all the chemicals to the treatment wells. USP also provided all interconnecting piping from the storage tanks to the well feed control devices. Emergency Response Module: USP provided an emergency eyewash and safety shower station complete with a water filter and emergency response water supply. USP pump skids provided potable water to the safety stations.
