Pilot Studies on Spray Irrigation of Meatpacking Plant Wastewater ANTHONY J. TARQUIN, Associate Professor Civil Engineering Department University of Texas at El Paso El Paso, Texas 79968 INTRODUCTION For many years the soil has been effectively used for treating municipal and liquid industrial wastes. Because of the increasing demands placed on available water supplied, tertiary waste treatment with subsequent water reuse will soon become mandatory. One of the most promising methods of renovating wastewater is through soil treatment. Wastewater-treatment through land application has been demonstrated for a number of wastes under widely varying conditions, not only in the United States, but in England (1, 2), Germany (3, 4), Israel (5, 6), South Africa (7), and New Zealand (8, 9). Liquid wastes with a wide spectrum of physical and chemical characteristics have been successfully treated by soil application including municipal sewage (7, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20), cannery wastes (21, 22, 23, 24, 25, 26, 27, 28), pulp and paper mill wastes (29, 30), dairy wastes (8, 31), vegetable and food processing wastes (32, 33, 34, 35, 36), wood distillation wastes (37), and poultry wastes (28). While the literature contains no references regarding full scale treatment of meatpacking plant wastes by land application, this method seems feasible and economically attractive. The purpose of this paper is to present preliminary results of pilot studies of a soil treatment system for meatpacking plant wastewater. BACKGROUND The project described in this paper is located at the Peyton Packing Company in El Paso, Texas. The climate in the El Paso area is subtropical, characterized by an abundance of sunshine throughout the year, high summer temperatures, low humidity, scanty rainfall, and a cool winter season. Rainfall throughout the year is light, with an annual mean of about 7 inches. Dry periods of several months duration without appreciable amounts of rainfall are not uncommon. Daytime summer temperatures are high, frequently above 90 F and occasionally above 100 F. Winter daytime temperatures are mild, rising to 55 to 60 F on the average, and dropping to the thirties anf forties at night. The Peyton Packing Company owns approximately 23 acres with the plant and parking lot occupying 3 acres and the remaining 20 planted in river-irrigated alfalfa. At the present time, the company slaughters 425 head of cattle and processes about 400 head of dressed swine in an 8 hour working day. However, plans are currently underway to expand to a 16 hour working day. A variety of meat products are made and packaged at the plant, including bacon, hot dogs, balogna, hams, and full lines of sausage and smoked meats. WASTEWATER CHARACTERIZATION In spite of the many by-products recovery processes employed in the plant, the wastewater discharged is very strong and quite typical of wastes generated by slaughterhouse-meatpacking plants (38). The effluent is subjected to primary treatment and grease skimming in a rectangular sedimentation basin providing a 30 minute detention time at peak flow. Table I shows the average concentrations of pH, BOD, COD, total Kjeldahl nitrogen, grease and total solids of the influent and effluent of the sedimentation tank. In addition, the range of each parameter is also shown for the tank effluent. 67
