Multi Media Filters are used for purpose of removing suspended solids, turbidity and impurities like iron and manganese.
System is generally consisting of different sized gravels and anthracite inside the body. Sometimes special filling materials will be used according to water quality to be filtered. For example, for more turbid waters or surface water turbidexantharicite or garnet - turbidex - anthracite combination will be used. Second duty of Multi Media Filters is to protect the equipment that will be located downstream. Multi Media Filters are used as a pre-treatment step for process water and drinking water applications or sometimes used for removal of turbidity coming from wastewater treatment systems.

Activated carbon filters are used mainly for chlorine removal but also used for removal of dissolved gases and organic compounds that give undesirable colour, taste and smell
to water. Activated carbons can be made from coal , coconut and wood but they have very wide surface area (1000-1500 cubic meterI gr). Productivity of activated carbon filter is determined by features of activated carbon used in filter, raw water quality
and correct selection of filtration velocity.

Disinfection with Ultraviolet Systems is the process for making microorganisms inactive without adding any chemical or oxidant to water This ultraviolet lights breaks DNA structure of microorganisms and makes them inactive unaffected. By this way, %99,9 average ratio
of disinfection productivity is supplied..

To be able to kill microorganisms with this system, Ultraviolet light must directly hit over them. For this reason, before water enters in ultraviolet system, parameters such as sediment, cloudiness must be removed from water. Sand filter or cartridge filters are recommended to be used before ultraviolet.
