Land treatment of latex waste water pretreated by pond system
1985
Chew, Kathy Lee Keok
Anaerobic and facultative ponds were used to treat latex concentrate wastewater before the effluent was upgraded by land treatment system. Anaerobic and facultative pond with aeral organic loading of 0.41 Kg.COD/m2-d and 0.16 Kg.COD/m2-d achieved 35% and 63% organic reduction after 30 days detention time respectively. Land treatment was found to be a feasible alternative to upgrade latex concentrate pond effluent. Slow Rate Application using Cholburi loamy sand and a hydraulic loading of 3.3 cm/d (0.08 Kg.COD.m2d) demonstrates its highest efficiency in upgrading latex concentrate pond effluent. The effluent quality at 30 cm depth even meets the standards of 4th generation effluent set up by Department of Environment, Malaysia. Soil, be it sand, loam or clay can be enriched by latex concentrate pond effluent as the organic matter and total N content increase significantly after being irrigated by latex concentrate pond effluent which is rich in NH3-N
