These handbooks are resource manuals and troubleshooting guides that contain a compilation of wastewater treatment information, data, operational material, process control procedures and problem solving, safety and health information, new trends in wastewater treatment administration and technology, and numerous sample problem-solving practice sets, many based on actual tests. The Handbook volumes review the wastewater operator's job-related knowledge as job requirements identified by the examination developers as essential for a minimally competent Class IV through Class I or Grade I through Grade V wastewater treatment plant operator. Every attempt has been made to make the three Handbook volumes as comprehensive as possible, while maintaining their compact, practical format.", "item_img_path" : "https://covers4.booksamillion.com/covers/bam/1/56/676/835/1566768357_b.jpg", "price_data" : { "retail_price" : "99.95", "online_price" : "99.95", "our_price" : "99.95", "club_price" : "99.95", "savings_pct" : "0", "savings_amt" : "0.00", "club_savings_pct" : "0", "club_savings_amt" : "0.00", "discount_pct" : "10", "store_price" : "" } }
