Car wash wastewater treatment using kapok fiber as adsorbent

Generally, cars have been used as main mean of transportation that requires cleaning regularly and will generate the car wash wastewater (CWW). In Malaysia, the CWW is released to the public drain without any treatment and threatened the aquatic livings as it consists of mainly oil and grease (O&...

In Malaysia, the CWW is released to the public drain without any treatment and threatened the aquatic livings as it consists of mainly oil and grease (O&G) and anionic surfactant (AS) that contributes to chemical oxygen demand (COD) concentrations and did not comply with Malaysia’s standard discharge limit (industrial effluent).

Car wash wastewater treatment using kapok fiber as adsorbent
description Generally, cars have been used as main mean of transportation that requires cleaning regularly and will generate the car wash wastewater (CWW). In Malaysia, the CWW is released to the public drain without any treatment and threatened the aquatic livings as it consists of mainly oil and grease (O&G) and anionic surfactant (AS) that contributes to chemical oxygen demand (COD) concentrations and did not comply with Malaysia’s standard discharge limit (industrial effluent). This study proposes an efficient and easily-operated approach to treat the CWW using kapok fibre (KF). The KF has been reported to have high affinity with oils where its lumen structures and lignin layers were reported to be responsible for its efficiency. In order to confirm the importance of lumen structure and lignin, delignification on the KF was done using sodium hydroxide, hydrochloric acid and chloroform. After delignification, the structures of modified- KF (MKF) were found to be crumpled. Moreover, the raw KF (RKF) and MKFs were then used to treat the synthetic CWW to remove the COD, O&G and AS in a batch-scale study. Overall, the RKF performed the best with removal of COD, O&G and AS at 80.8, 100.0 and 24.4 % respectively at the optimum operating pH of 9, the dosage of 1.0 g and a contact time of 30 minutes.
