The Cost

The Citrus Processing Industry is faced with increased pressures from a number of different sources to reduce water consumption and wastewater discharges. The Florida Water Management Districts are moving toward more restrictive limits on consumptive use permits. The United States Environmental Protection Agency (EPA) and the Florida Department of Environmental Protection (DEP) are moving toward zero discharge limits for industry wastewater discharges to surface waters, wherever possible. The cost of water consumption and wastewater treatment and disposal are increasing, therefore, there is a significant cost incentive for industry to reduce water consumption and wastewater discharge. A logical and economical approach to addressing this issue is by reduction of: • In-plant water use • Wastewater volume • Wastewater concentrations Implementation of a water use and waste reduction program establishes a pro-active environmental image for the corporations and industry as a whole.

Transfer Programs

Technology transfer is an important activity within the ll.S. Environmental Protection Agency. Specific technology transfer programs such as the activities of the Center for Environmental Research Information, the Innovative and Alternative Technology Program, as well as the Small Community Outreach Program are used to encourage the utilization of cost-effective municipal pollution control technology. Case studies of three technologies including a plant operations diagnostic/remediation methodology, alternative sewer technologies and ultraviolet disinfection are presented. These case studies are presented retrospectively in the context of a generalized concept of how technology flows from science to utilization which was developed in a study by Allen (1977). Additional insights from this study are presented on the information gathering characteristics of engineers and scientists which may be useful in designing technology transfer programs. The recognition of the need for a technology or a deficiency in current practice are important stimuli other than technology transfer for accelerating the utilization of new technology.

Pulp Paper

The pulp, paper, and paperboard industry in the United States is the larqest industrial user of water with half of the facilities discharging wastewater directly to our Nation's waters. The major pollutants of concern have historically been the conventional pollutants: biochemical oxygen demand (BOD5), total suspended solids (TSS), and pH. Biological treatment systems are currently employed to reduce these pollutants. Sludges generated by these treatment systems have been categorized as nonhazardous and are generally landfilled. Under the Clean Water Act, the Environmental Protection Agency (EPA) has promulgated all the reguired regulations for this industry. The national regulations are applied to individual pulp and paper mills through permits issued by EPA Regional or State staff. Permit limits can be written that are more restrictive than the national regulations to protect local water guality. In its current projects concerning the pulp and paper industry, EPA is focusing on the reduction of toxic pollutants. The Agency is conducting a joint EPA/industry program to study dioxin discharges at bleached kraft mills. The Agency will also undertake a comprehensive review of the pulp and paper regulations in 1988.

The Impact

Dioxins and furans are toxic chemicals. A draft report released for public comment in September 1994 by the US Environmental Protection Agency clearly describes dioxin as a serious public health threat. The public health impact of dioxins may rival the impact that dichlorodiphenyltrichloroethane (DDT) had on public health in the 1960’s. According to the United States Environmental Protection Agency(USEPA) report, not only does there appear to be no “safe” level of exposure to dioxin, but levels of dioxin and dioxin-like chemicals have been found in the general US population that are “at or near levels associated with adverse health effects.”  With this in mind the purpose of this paper is to provide an overview of the current dioxin and furan emissions from industry in South Africa, in terms of compliance with the relevant emission limit values (ELVs) and the current challenges faced with the monitoring and analysis thereof.

Radon Testing

Radon testing by using open-faced charcoal canisters is a cheap and fast screening method. Many laboratories perform the sampling and measurements according to the United States Environmental Protection Agency method - EPA 520. According to this method, no corrections for temperature are applied and corrections for humidity are based on canister mass gain. The EPA method is practiced in the Vinca Institute of Nuclear Sciences with recycled canisters. In the course of measurements, it was established that the mass gain of the recycled canisters differs from mass gain measured by Environmental Protection Agency in an active atmosphere. In order to quantify and correct these discrepancies, in the laboratory, canisters were exposed for periods of 3 and 4 days between February 2015 and December 2015. Temperature and humidity were monitored continuously and mass gain measured. No significant correlation between mass gain and temperature was found. Based on Environmental Protection Agency calibration data, functional dependence of mass gain on humidity was determined, yielding Environmental Protection Agency mass gain curves. The results of mass gain measurements of recycled canisters were plotted against these curves and a discrepancy confirmed. After correcting the independent variable in the curve equation and calculating the corrected mass gain for recycled canisters, the agreement between measured mass gain and Environmental Protection Agency mass gain curves was attained.
