Dr. G. Expert has applied his background in chemical engineering, particulate filtration, and membrane separation technology to the areas of water and wastewater management, pollution prevention, and the treatment of industrial wastewaters and hazardous wastes. He is knowledgeable of waste minimization, waste surveys and audits (involving sampling and chemical analysis protocols), industrial water management and treatment, project management, process design and wastewater treatment equipment selection, control systems for treatment plants, operator training programs, and troubleshooting of existing treatment plants. He has consulted for clients in the electronics, semiconductor, disk drive, metal plating and finishing, chemical, oil, mining, textile, pulp and paper, laundry, ceramics and paints, pesticide, food and beverage, biotechnology, and pharmaceutical industries.

Expert's experience in wastewater treatment facility design includes work on an effluent treatment system for an oil refinery using DAF, microfiltration, reverse osmosis, and GAC. He worked on the process design and equipment specification of a 1 MGD treatment plant for the removal of selenium from agricultural drainage water. He was also involved in the design and development of a sophisticated computer control system for a wastewater treatment plant for a major semiconductor company.

Expert has over 20 years of experience with process and engineering design of filtration equipment, membrane separation systems (including reverse osmosis, ultrafiltration, and microfiltration), ion exchange, evaporators, biological treatment, and general treatment systems.

Experienced with many aspects of pollution prevention, Expert is an expert in environmental compliance audits, performance audits, and site audits. He is extremely knowledgeable of hazardous waste regulations, particularly for California. He is a Registered Environmental Assessor in California. He has worked on audits and chemical analysis surveys for semiconductor manufactures.

Expert provides his clients with cost effective solutions and detailed recommendations to minimize waste production and optimize water usage by operational improvements, production process equipment, chemical changes, operator training programs, and improved automation. He is familiar with hazardous waste reduction systems in the industries that produce heavy metals, pesticides, paints, dyestuffs, solvents, and oil and grease.

Expert has both process design and operational experience with the treatment technologies used for recovery and reuse, including filtration, microfiltration, ultrafiltration, reverse osmosis, ion exchange, activated carbon, evaporation, dewatering filter presses, and drying equipment. He was a Project Manager for technology demonstration projects carried out for the California DHS Toxic Substances Control Division and the EPA SITE program. The former was a waste reduction and recycling system for heavy metals and pigments used in the paint and ceramics industry. Both water and separated waste were reused through the processes of microfiltration, filter press dewatering, drying, and vitrification to form a ceramic substance. The EPA SITE project was on the removal of high concentrations of heavy metals (copper and zinc) from acid mine drainage water.

A significant portion of Expert's career has involved process design, equipment selection, and troubleshooting of wastewater treatment systems for particulates and heavy metals removal encountered in the metal finishing industry. He has worked with copper, nickel, lead, zinc, and chromium. He is familiar with ultrafiltration, reverse osmosis, ion exchange, chemical coagulation and flocculation, neutralization, pH control, activated carbon, particulate filtration, sludge dewatering and drying, and chemical oxygen demand removal. He has designed and installed over 40 wastewater treatment systems of sizes up to 250,000 gallons per day for the groundwater remediation, metal plating, ceramics production, semiconductors, electronics, and disk drive industries.

Familiar with all aspects of filtration and membrane technology, Expert has designed and installed filtration and membrane separation equipment for desalination, process water treatment, particulate and fine filtration of beverages and wine, and cooling tower recirculation systems. He is extremely knowledgeable of treatment methods employing microfiltration, ultrafiltration, and reverse osmosis systems.

Expert has experience with treating groundwater for the removal of heavy metals, particulates, oil, and organic substances by activated carbon or catalytic oxidation.

Expert has experience with the design, selection, programming, and installation of computer and PLC (programmable logic controllers) based control systems, including visual display units. He has been involved in projects ranging from pH control for neutralization and flocculation to complex, multi-process control systems for treatment plants that require monitoring, alarming, sequence control, PID control, and information logging.

Expert has recently designed and installed a continuous, online process monitor for copper and nickel. This system uses ICP technology and automatically samples, analyses, provides process alarms, and prepares daily and monthly reports for treated wastewater prior to sewer discharge. The system is capable of analyzing up to 20 elements and can be used for the monitoring of most process streams requiring metals analysis.

Expert has designed numerous desalination systems, including the commissioning of large units and trouble-shooting.


Expert advised client on setting up a microbiological testing laboratory, including specification of equipment and technician training. Expert evaluated the market for a new polymer developed by a major chemical company, and advised on potential applications and large customers for the new product.
