Conventional aerated tank technology is widely applied for post treatment of natural rubber processing wastewater in Southeast Asia; however, a long hydraulic retention time (HRT) is required and the effluent standards are exceeded. In this study, a downflow hanging sponge (DHS) reactor was installed as post treatment of anaerobic tank effluent in a natural rubber factory in South Vietnam and ...
A pilot-scale experiment of natural rubber processing wastewater treatment was conducted using a combination system consisting of a two-stage up-flow anaerobic sludge blanket (UASB) and a down-flow hanging sponge (DHS) reactor for more than 10 months. The system achieved a chemical oxygen demand (COD) removal efficiency of 95.7% ± 1.3% at an organic loading rate of 0.8 kgCOD/(m3.d). Bacterial ...
Did you know that most of the products we refer to as being rubber aren’t actually “real” rubber? Real, natural rubber comes from the rubber tree most commonly found in countries like India, Indonesia and Thailand. To make natural rubber, also called gum rubber, the rubber tree is tapped to release latex, a light, milky substance that is refined into natural rubber sheets. The ...
ECO Green Equipment releases a review of the many different uses and after-market products utilizing recycled rubber. The Many Uses of Recycled Rubber If you think the best use of rubber is for your car tires, then think again! Secondary rubber products are used in many everyday products and places. You might be surprised to learn about the different industries using ...
An investigation has been carried out in which recycled rubber granulates are added to damp rectangular tubes. A series of experiments have been carried out on the tube filled at different rates of filling. A model for calculating the displacement-force frequency responses has been derived by means of the Dynamic Stiffness Method (DSM) taken into account the assumption of internal resonance in ...
