Schaub Umwelttechnik GmbH

Schaub Umwelttechnik GmbH, operating as Schaub Systems, is a German engineering and manufacturing company based in Augsburg with 50 years of expertise in dosing and handling systems for lime, powdered activated carbon (PAC), soda, and other sorbents used in water treatment and flue gas cleaning. Led by Managing Directors Rudiger Meyer and Michael Schaub, the company delivers turnkey systems from initial concept through commissioning, covering design, engineering, construction, and after-sales service. Schaub Systems' core product lines include Kalkmilchanlagen (lime milk preparation and dosing plants) for water softening and hardening, featuring both wet slaking and dry slaking (Kalktrockenloscher) configurations. The company's Aktivkohlenlagen handle PAC storage, conveying, and precision dosing for the fourth treatment stage (Spurenstoffelimination) targeting trace contaminants in wastewater. A proprietary gravimetric container slaking process (gravimetrisches Behalterloschverfahren) represents a key technical innovation used in major modernization projects. Schaub Systems also provides systems for soda, magnesium oxide, bentonite, and zeolite handling. Applications span drinking water treatment, wastewater treatment (including sewage sludge conditioning and acidic neutralization), flue gas scrubbing for power plants and incinerators, and complex industrial installations. Notable reference projects include modernizing the Landeswasserversorgung Langenau drinking water facility, delivering PAC dosing systems for the Hauptklarwerk Stuttgart-Muhlhausen fourth treatment stage, and supplying two lime slaking plants for the Umm Al Hayman mega-wastewater treatment facility in Kuwait.
