PILOT PLANT OBJECTIVES
The objective of a pilot limestone contactor plant study is to
determine whether it is suitable as a stabilization treatment
by assessing the cost, performance and feasibility of the process.
The suitability of the limestone contactor is mainly dependent
on raw water characteristics such as pH, alkalinity and temperature.
These along with using correct choices of design and operating
variables will determine the success of a limestone contactor
operation. These variables are determined from pilot study.
Engineering Design Variables:
1. Media size
2. Chemical constituents / purity of media
3. Filtration rate
4. Maximum flow rate
5. Contact time
6. Limestone bed depth
7. Recharge level
8. Location in the treatment train
Operating Variables:
1. Filter backwashing frequency
