Major Cost Areas
In our experience, we have found that the majority of problems related to operating problems, including microbial contamination and premature breakthrough, are the result of improper activated carbon filter design and incorrect backwashing and sanitizing procedures. There are 3 major cost areas involved:
Capital cost (mainly equipment such as ACF, particularly those incorporating a false bottom or nozzle plates)
Operating costs (such as water usage in backwashing and sanitizing steps, and especially wastage, which is a key part of any corporate sustainability program, downtime etc)
Filtration media costs (carbon change out and replacement)

Advantages of Carbochem’s Under Drain Vs. Nozzle Plates
Maximize use of vessel volume and eliminate dead space beneath the nozzle plate
Reduce CAPEX and OPEX of ACF
Minimize the major source of potential microbial contamination by eliminating the dead space beneath the nozzle plate and providing thorough scouring of the bottom head due to the optimum location of the nozzles
Minimize water consumption to operate the ACF
Lower backwash flow rate to achieve required bed expansion
Minimize water consumption to operate the ACF
Eliminate the requirement for a bed of supporting media which adds to the cost and impacts the backwashing efficiency (different densities are not compatible)
Supporting media is also more prone to microbial contamination if not maintained/sanitized adequately
ACF with nozzle plates are more susceptible to channeling (and premature breakthrough) due to problems with the nozzles (damaged, incorrect configuration etc)
Easy maintenance and GAC replacement with minimum downtime
Eliminates dangerous internal pressure differentials that exist with filters incorporating nozzle plates or false bottoms
Benefits of Carbochem’s Proprietary ACF Design
Optimum configuration to maximize efficiency and performance (Mass Transfer Zone of the GAC, service life) and minimize the capital cost (in terms of size and shape of ACF)
Employ proprietary under drain (U/D) which eliminates the nozzle plate and void/dead space internally
Lower backwash flow rate to achieve required bed expansion
Minimize water consumption to operate the ACF
Minimize microbial contamination
Reduce energy consumption and steam requirement
Reduce formation of GAC fines
Easy maintenance and GAC replacement with minimum downtime
Carbochem U/D system eliminates dangerous internal pressure differentials that exist with filters incorporating nozzle plates or false bottoms
Small footprint reducing construction cost and physical plant size
