The first step will involve separating the solids using a series of bar screens; as the name implies, these typically encompass metal bars spaced about an inch apart to capture a number of the bigger solids.
This subject provides an summary from the hybrid photocatalysis-membrane processes as well as their achievable purposes in water and wastewater treatment. Various configurations of photocatalytic membrane reactors (PMRs) are described and characterized. They incorporate PMRs with photocatalyst immobilized on/from the membrane and reactors with catalyst in suspension.
The final section is to treat the remaining water and biosolids, or sludge. Gravity separates organic and natural waste from heavier grit, which may be deposited within a landfill.
