Sink Equipped With Wastewater Filter System

Abstract

The Sink Wastewater Filter System is designed as an alternative to reduce pollution in drains and domestic sewage lines caused by oil and suspended solids which can harm the environment. As a result of this situation, the channel is often clogged, thus increasing the maintenance cost as well as contributing to mosquito breeding grounds. The product is made of 64cm x 30.5cm x 30.5cm x 30.5cm fiber and comes with filters from natural materials as the main medium i.e. coconut coir, coal, river rock (5mm – 10mm), coarse sand (0.45mm) and fibre sponge. Researchers develop a disposable and recyclable filter system.  The sample of restaurant sink wastewater is tested for pH, BOD, COD, TSS and Oil & Grease before and after being filtered and compared with the Standard Environmental Quality Act 1974 (EQA). The data obtained show that there is a decrease in the rate of water pollution before and after filtering. The pH value shows a reading of 5.0 (before) and 4.7 (after). The BOD test showed readings of 95mg/L (before) and 68mg/L (after). Both parameters do not comply the EQA standard of 5.5 – 9.0 for pH values and 20mg/L – 50mg/L for BOD. The COD test recorded readings of 184mg/L (before) and 96mg/L (after). The Total Suspended Solid Test (TSS) showed values of 33mg/L (before) and 23mg/L (after). The O&G test showed readings of 15.8mg/L (before) and 9.8mg/L (after). The results showed that the Sink Wastewater Filter System affected several parameters such as COD, TSS, and O&G. However, it was found that the pH and BOD values were decreased but did not meet the requirements of the Standard Environmental Quality Act 1974 (EQA). As conclusion, the Sink Wastewater Filter System is significant in reducing the emissions of pollutants before being disposed of into the natural ecosystem of water resources, as well as having a positive impact on individuals and organizations.
