Face Piping Multimedia and Activated Carbon Filter Systems
Multi Media Filters are generally used for purpose of removing suspended solids, turbidity and other impurities like iron-manganese.Standart control valves don’t have enough capacity to handle high capacities more than
20 m3 - hour, therefore surface piping method will be used for multimedia filter systems and activated carbon systems.
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.

Duplex systems consist of two softening units and regeneration process is set with flow control in these systems.
When resin exchange capacity is exhausted, regeneration process which consists of five main steps that are backwash,brine and slow rinsing, rapid rinsing and refilling salt tank starts. In regeneration, resin leaves hardness ions to water and sodium ions are taken back again from the brine prepared in the salt tank so that system is ready to another service cycle.
