Performance Evaluation And Application Of Tube Settlers In Water And Wastewater Treatment

Abstract

Water Quality Is An Essential Aspect Of Human Health, And Household Water Often Contains Suspended Particles, Silt, And Other Impurities That Reduce Its Clarity And Usability. This Project Focuses On The Design, Fabrication, And Evaluation Of A Home-scale Tube Settler, A Simple And Low-cost Sedimentation Unit That Improves Water Quality Before Filtration Or Use. The Tube Settler Consists Of Inclined Tubes Arranged In A Small Container, Which Accelerates The Settling Of Suspended Solids And Reduces Turbidity. Domestic Water Samples Were Collected From Sources Such As Overhead Tanks And Bore Wells, And Water Quality Analysis Was Performed Before And After Treatment. Parameters Including Turbidity, Total Suspended Solids (TSS), PH, Dissolved Oxygen (DO), Biochemical Oxygen Demand (BOD), Chemical Oxygen Demand (COD), And Odour Were Measured. The Results Show That The Tube Settler Effectively Reduced Turbidity From 18 NTU To 5 NTU And TSS From 42 Mg/L To 14 Mg/L. Improvements In Colour, Odour, And Overall Water Clarity Were Also Observed, While Chemical Parameters Remained Within Safe Limits. The Study Demonstrates That Tube Settlers Are A Practical, Space-efficient, And Economical Method For Pre-treatment Of Household Water, Enhancing The Performance Of Filtration Systems And Ensuring Safer Water For Domestic Use. This Project Highlights The Potential Of Small-scale Sedimentation Systems In Improving Water Quality In Homes With Minimal Cost And Maintenance.
