'8. rd 1 -0 0 . - PREFACE ,. The need for training in the water pollution control field Gilbert (1981) states that, based'on continuing continues to grow. changes in current programs and activities, the training programs provided tfy ...In institution or organization must be responsive to' the information, knoOledge, or skill ga,j that exists between what,-, an individual already knows or cap do and what the individual needs to know .2r.be able to do to accomplish-a given task. Example of changinA areas with training implications include wastewater - treatment technology and water quality assessment. Recent USEPA reports Gray, et al.', (1979)'and,Hegg, et al., (1979) suggest that training needs.do exist in the areas of wastewater treatment system management and process control. - Major reasons given for-the fact that many wastewater treatment plants currently in operation are not in compliance with their NPDES permits include lack of understanding by operators of the wastewater treatment process and the inability of operators to The Gen6ral' apply process control knowledge to inplant conditions. Accounting' Office report (1980) showed 97 percent of the,21a treatment facilities surveyed to be in violation of their effluent discharge permits. I As technology alone cannot solve the problems, it is important to realize 'that a wellAltrainde workforce is essential to cl'ean up Most practitioners agree and control our water pollutibn problems. that training is critical to the,improyement of performance of personnels With training comes the need for training materials and -it is the intent of this monograph to assist in.-identifying and locating instructional and reference materials specific to the wastewater treatment process of anaerobic digestion. \ LeStning resources and referende materials are assembled here to assist trainers and instructors in the development of training The learning resources are often segments of illustrative rograms. aterials on anaerobic digestion taken from a chapter or section of publication or other learning resource that prbvides additional These resources are to serve only as a guide in i formatioil. s letting appropriate training materials'an& should not be consider d structure or total program. a a .
