TYPICAL CONTACTOR - UNH

Maximum Level The maximum level of limestone in a contactor can be determined using EBCT and superficial flow rate by using the worst-case of influent water chemistry such as lowest water temperature (Cox, 1930) and pH (Spencer, 2002). Computer models such as DESCON and STASOFT or design curves from DVGW (1998) can be used to aid in ...

Absorber Tower - an overview | ScienceDirect Topics

6.2.2.2 The contactor. The contactor (also called an absorber) is the workhorse of the dehydration unit. It is in the contactor where the gas and liquid are mixed and where the actual water removal takes place. The contactor is a typical absorber tower properly sized with the process objective in mind. The feed gas flow rate is the most ...

Calcite Contactors for Corrosion Control in Small Systems

Calcite contactors use limestone to add calcium carbonate to water, which raises pH, and adds alkalinity. • Advantages: – Easy and safe to operate – Reduced operating cost – Self adjusts the water pH without risk of alkali overdose – Increases alkalinity – Requires minimal maintenance and operator skill

design criteria for printing - UNH

the design of limestone contactors. This computer program has been used by Spencer (2002) to design the limestone contactor facility in Mars Hill, Maine. This program is also recommended for the design of a limestone contactor by USEPA (2003). DESCON calculates the depth of limestone required in a contactor based on the influent water chemistry,

PROCESS DESCRIPTION

In a limestone contactor, water flows through a bed of crushed sieved limestone in a similar way as it would flow through a sand filter (Spencer, 2000). The pH of water that flows through the limestone bed will be adjusted until it nears equilibrium with calcium carbonate (CaCO3(s)). The components of a contactor include a contact tank, limestone
