Part 3 describes treatments, including fermentative biohydrogen production processes and vertical and horizontal flow constructed wetlands and biofilters
. B&w process diagrams are included.
are employed for removing butanol, acetone, xylene, toluene and other volatile organic compounds from air.
Experimental investigation and assessment of the effectiveness of peat media made from sulfur compounds helps with making suggestions based on designing efficient and cost-effective biofilters
for different industries (Chung et al.
First, identify the behaviors of different nitrogen compounds until the activation of the biofilters
. Subsequently calculated performance indicators VTR (Volumetric Conversion Rate), STR (Surface Conversion Rate) and PRN (Percentage of TAN removal).
For this second edition, they have fully revised and updated the original material and added new chapters on air binding, filter-clogging algae, carbonate precipitation through alkalinity analysis, polymer retention analysis, biomass and biofilm determination, and biofilters
. Other topics include organizing a filter evaluation program, backwash bed expansion analysis, top of gravel footprint analysis, sieve testing procedure, and sludge retention profile.
Ayeng also visited the workshop, during his visit and said, "We are in debited to INDBATT1 for conducting such a useful and important workshop about water purification and construction of biofilters
as we all are aware of the grave water-borne diseases prevalent in the area and unhealthy condition of Nile River water".
Seaweeds provide an alternative to bacterial biofilters
. They consume nutrients directly from the seawater [carbon (C), nitrogen (N), and phosphorus (P)] and their biomass can be easily removed from the system.
require four to six weeks to become properly established.
