The design of a lime feeder requires some knowledge of chemistry, especially about alkalinity and acid base reactions. In addition, fluid mechanics, hydraulics and water treatment knowledge is required. There is a list of some useful references to acquire that understanding:
1. Water Chemistry; V. L. Snoeyink & D. Jenkins (1980)
2. A Problem Solving Approach to Water Chemistry; J. N. Jensen (2003)
3. Surface Water Treatment for Communities in Developing Countries; Schultz and Okun (1992)
4. Lime, the versatile chemical. National Lime Association (2007)
5. Water Chemistry (CEE 6530) course notes
6. Sustainable Small Scale Water Supplies (CEE 4540) course notes
