| Summary: | Traditional and modern technologies have been used to remove colloidal particles
from wastewater, including coagulation/ flocculation which is a common solidliquid separation process in water treatment. Hemp plant-based flocculants were
chosen for their extractable cellulose as a base material for biomaterial
composites, solving sustainability and toxicity issues found in inorganic coagulants
and synthetic polymer flocculants. The research involved TSS, TDS, turbidity,
COD, BOD, and biodegradability tests to assess the suspended particle removal
efficiency and environmental safety of using these natural flocculants. As a result,
cationic cellulose (Boehmeria nivea) flocculant or CC was more effective in
removing suspended particles and turbidity in artificial raw water and surface raw
water compared to conventional coagulant Poly Aluminum Chloride (PAC). CC
also produces less sludge volume compared to PAC which is good for sludge
handling, but higher sludge density. CC showed good biodegradability by
microorganisms. Biodegradability tests showed that CC is an environmentally
friendly flocculant, with good degradability in liquid and solid conditions, reducing
BOD and COD values and being a substrate for microorganisms. |
