<p align ="justify">The dairy-tofu industry is new innovation from tofu industry. Dairy-tofu industry is different from the tofu industry in general because of the additional process using cow's milk. For that, we need a new innovation in wastewater treatment industry. Anaerobic Baffled Reactor (ABR) is a type of anaerobic reactor that has a baffle in it that is useful to provide an opportunity for suspended microorganisms to remove wastewater. Constructed wetland (CW) is an artificial wetland types and sizes can be designed to the needs of its processing capacity. Wastewater used in this study were drawn from a dairy-tofu industry in Lembang, West Java. This study aims to look at the efficiency of dairy-tofu industry wastewater removal by the nitrogen and phosphorus parameters by using ABR and CW. Variations of ABR are detention time and influent concentration. And variations of CW are detention time and the type of plant. The capacity of ABR is15.84 liters and use a coconut shell as a filter media. CW which is an advanced processing unit has two plants variatons, those are Scirpuss grossus and Echinodorus palaeofolius. Initial characteristic of dairy-tofu wastewater for COD, BOD, Phosporus and NTK are 12614,4 mg/L, 5251,6 mg/L, 25,07 mg/L and 420 mg/L. Provision for the optimum parameters of N and P removal in a series that using ABR variations with loading 3 kg/m3day (influent concentration 6000mg/L and 2 days detention time). For CW the optimum variations is using Scirpuss grossus and 7 days detention time. The phosporus can be removed up to 95% while the NTK able up to 93 <p align ="justify">
