Siemens adds new process control system

Siemens Water Technologies announced a new addition to its technology portfolio with the purchase of the Clearlogx Process chemical feed system.  Siemens and MarMac Water, LLC, signed an agreement to purchase the technology, which combines chemical addition and proprietary controls for treatment of water and wastewater.

Siemens will integrate the technology into its Memcor membrane systems, which will support greater membrane performance for especially difficult-to-treat water sources.

The Clearlogx automated chemical feed system enhances organic contaminant removal in water and wastewater, while simultaneously improving membrane and conventional filter performance. In traditional systems, increased coagulant dose rates can achieve higher soluble organic removal, however at the expense of elevated membrane fouling. To avoid this, a controlled coagulant feed is necessary. The Clearlogx system controls the addition of acid, coagulant and chlorine dosing systems. The proprietary technology decreases membrane fouling and reduces the formation of disinfection byproducts.
