Retention vessels engineered for optimal contact time between chemicals and process fluids. Baffled design ensures complete reaction and treatment efficiency for disinfection, coagulation, and chemical conditioning and treatment applications.
Glycol storage tanks for HVAC and deicing applications. Heating, insulation and leak prevention for ethylene and propylene glycol.
Chemical-resistant acid storage tanks with linings and ventilation.
Urea storage tanks for AdBlue, DEF and fertilizer applications.
Industrial bespoke storage tanks tanks for water, wastewater and chemical storage.
Contact tanks provide the residence time necessary for chemical reactions to reach completion. Internal baffles create plug-flow conditions, preventing short-circuiting and ensuring all fluid elements receive the designed contact time for effective disinfection, coagulation, or chemical conditioning and treatment.
Contact tanks are engineered to provide precise hydraulic retention time (HRT) for chemical conditioning and treatment processes. The baffled design creates a serpentine flow path that maximises contact efficiency while minimising tank volume. These vessels are critical in water treatment for chlorine contact, in wastewater for disinfection, and in industrial processes requiring controlled chemical reaction times.
Chlorine/UV contact for pathogen inactivation
Coagulant contact for particle destabilization
Ozone contact and chemical oxidation
Controlled chemical reaction timing
