Since its incorporation in 1988, David H. Paul, Inc. (DHP) has been 100% committed to providing practical, cost-effective, unbiased high-tech water treatment training, certification and technical services. TRAINING DHP is the world's leader in providing training for all high-tech water treatment technologies. Our expertise allows us to train beginners, operators and engineers. We offer “just in time” training to address real-time needs and longer, in-depth certification opportunities. Our courses and seminars are both online and hands-on. We have the knowledge you and your team need to excel in every high-tech water treatment job. CERTIFICATION We offer four levels of Reverse Osmosis Specialist Certification training and RO & HPWT Certification. Certification has value. Certified personnel increase value to customers, owners and investors by making fewer costly mistakes and by catching problems at an earlier stage. If an individual earns ROS-I, ROS-II, ROS-III and ROS-IV, their promotion potential and pay potential increases significantly. TECHNICAL SERVICES If you are looking for a cost-efficiency audit or an autopsy or customized training, we are your solution. We provide in-person consulting and training and e-consulting. You can access decades of water treatment knowledge and experience on your time and without costly travel. We help to save facilities costs and damage to equipment. DHP eliminates the speedbumps encountered in your facility and helps you to optimize efficiency. Finally, we have launched our DHP Neptune Water Treatment App – the app for every water treatment professional. Neptune places features like conversion factors and calculator in the palm of your hand. We offer RO equations, a list of chemical compounds and a glossary of terms commonly used in the water treatment industry. Further, you can use Neptune to access online consulting with DHP instructors. We are ready to partner with you.
