Water Treatment Plant Design: Complete Guide with Excel Tool

Design a manual inclined coarse screen for water treatment by calculating opening area from flow and velocity, then determine width, length, bar spacing, and freeboard.

Use this Excel tool to design a water treatment plant's flocculation stage, entering blue box values to automatically calculate basin volumes, compartment layouts, paddle wheel dimensions, and optimized, economical configurations.

Explore the inlet structure of a circular clarifier, comparing central and peripheral fields, with middle effluent, perforated baffles, sedimentation to the hopper and launders.

Master traditional sand filtration by comparing slow and rapid methods, remove suspended solids to below 0.3 NTU, and apply design calculations with Excel for clear water and disinfection.

Begin with rapid sand filtration after coagulation, flocculation, and clarification to remove suspended solids and polish water, noting its purely physical action and limited pathogen removal.

Design rapid sand filters by sizing unit dimensions from the rate of filtration and selecting media layers, troughs, and wash considerations for reliable operation.

Create an excel spreadsheet to design rapid sand filtration, using blue inputs and yellow outputs to compute daily flow, rate of filtration, surface area, and functional units.

Design a slow sand filter using the rate of filtration to size top area and media layers. Apply to a 50,000 m3/day case with five rectangular filters and freeboard.

Explore the disinfection step in water treatment, comparing chlorination, UV, and ozonation, their design considerations and monitoring, targeting bacteria, viruses, and protozoa to ensure safe water.
