A local hotel in Indonesia has been troubled by the problem of sewage discharge for a long time. The local government does not allow oily wastewater to be discharged directly into the sewer pipe, so they found our company online. Our company recommended that the hotel use P-A150 model of automatic oil-water separation equipment with slag dredger, under our guidance installation work smoothly. After that, the hotel took the drainage treated by the Cngreasetrap oil and water separator to the local relevant departments for testing. The (PH/BOD/Oil&Grease TSS) discharge in the drainage reached the standard and solved the sewage discharge problem of the hotel!
