This paper presents a new developed pneumatic mechanism for lime dosing system in water treatment application. Technically, a choke formation due to scaling problem in such existing water treatment system utilising pump as the transferring medium has caused the high cost of operation due to scheduling maintenance and replacement of pump tubing. In that sense, the pneumatic system will be a new advancement in replacing the transferring medium. In this work, the air regulator is used to control air pressure at several levels. At the same time, there is one valve that is installed to control the airflow the regulator (air compressor) to the pneumatic cylinder cartridge. The assessment is conducted for water with 10% of lime concentration on water sample 25 PPM as the standard lime concentration for water treatment plant as the domestic usage in Malaysia. The trend of dosing rate for the present novel lime dosage utilising a pneumatic system shows consistency of increment with the increment of applied air pressure during the dosing process.
