The drinking and mineral water samples obtained from different geographical locations had concentrations of the selected minerals lower than the standard limits, except for manganese, arsenic, and fluoride. The concentrations of manganese and arsenic in two mineral water samples were slightly higher than the standard international recommended limits. One mineral water sample had a fluoride concentration higher than the standard limits, whereas manganese was not detected in nine drinking and mineral water samples. Most of the selected minerals found in the tap water samples were below the international standard limits, except for iron and manganese. The concentrations of iron and manganese in the tap water samples were higher than the standard limits, which were obtained from one and three of the studied locations, respectively. The potable water obtained from various manufacturers and locations in Peninsular Malaysia is safe for consumption, as the minerals concentrations were below the standard limits prescribed by the Malaysian Food Regulations of 1985. The data obtained may also provide important information related to daily intake of these minerals from drinking water.

The design standards of the iron and manganese removal system by membrane filtration were investigated. The membrane filtration after pre-chlorination could remove iron completely and could remove around 70% of manganese. In the case of manganese concentration being more than 0.05 mg/l, the membrane filtration could remove them completely after the deposition in the oxidation tank. The concentrations of iron and manganese were reduced more than 90% by the oxidation tank and were reduced until under the detection limit after the membrane filtration. The economic comparisons between the rapid sand filtration system and this membrane filtration system in a small capacity and a middle capacity were investigated. The 15 years total costs of the membrane filtration system were estimated to be smaller than or around equal to the rapid sand filtration system in both capacities.

“aged” biofilter media was adopted as the inoculum to accelerate the maturation of biofilter for iron and manganese removal in the start-up of filter column. morphology of “aged” biofilter media and new quartz sand was observed with SEM. The results indicate that the “aged” biofilter media coated by a large quantity of bacteria which reduces the start-up time to 30 daysand affords strong Mn-removal efficiency at the beginning of the process. This method probably can be used for the start-up of new filters when there are well-established biofilters around.

Currently, methods of water purification and aqueous solutions leading to effective reduction of introduced chemical compounds into water purification systems have become the subject of research. Physical methods have become an alternative, because by subjecting water and aqueous solutions to UV (ultraviolet) radiation or magnetic fields (MF), either ultrasonic or electric, it is possible to influence the change of structure, which results in changes in the properties of water and aqueous solutions. This paper attempts to verify the influence of a weak magnetic field on the removal of iron and manganese compounds in the filtration process on gravel of 1–2 mm granulation, sand of 0.4–0.8 mm granulation, activated alumina and activated carbon. The conducted research proved that MF has a significant influence on the effectiveness of iron and manganese removal from water in the case of alumina, while in the filtration process through other filter materials the effect of MF was small.
