Water Filter Design Calculations

There are multiple variables in sizing industrial water multi media filters that are beyond the scope of the multi media filter calculator below.

Water filter design calculations. In this hands on activity students investigate different methods aeration and filtering for removing pollutants from water. Because most filter media work effectively at a flow rate of 3 gpm per sq ft of filter area a filter tank that has a diameter of 4 ft will allow a filtration flow rate of 37 5 to 62 5 gpm. Filter design and analysis. For industrial water filtration purposes vertical filter bed speeds ideal service flows varying between 10 m h and 25 m h are used depending on the quality of the to be treated water.

Working in teams they design build and test their own water filters essentially conducting their own dirty water projects a guiding data collection worksheet is provided. Step 1 enter continue reading filter system flow rate calculator. The objectives of this work were to estimate the water demand for a certain comminuity and to present design steps and calculations for the required units of a wtp the design of the wtp units was. This is the design of the rapid sand filter type filtration bed.

Examples include water pressure temperature flow rate available foot print and cubic feet of media per tank. Removal of inorganic as well as organic matter is aided by this method. Design of rapid sand filter. Therefore these industrial ml filter guides should only be used for quick estimates.

A minimum of 2 units is mandatory in a treatment plant. Filtration is a vital process in the treatment of water in treatment plants. This page is the index of web calculator that design and analysis analog filters. 2 filtration 5 3 filter operation 25 5 3 1 rapid gravity filtration 25 5 3 2 backwashing 25 5 4 filter control systems 26 6 activated carbon filters 29 7 interaction with other treatment processes 31 7 1 prefiltration treatment 31 7 2 in line filtration 31 8 process monitoring and control 35 9 operating procedures associated with normal process conditions 37.

This flow rate can be measured in the amount of gallons per minute that can flow through one square foot of filter media square area. The above multi media filtration calculator calculates the diameter of a round multi media filter mmf based on the filter bed speed as input. Vertical filters usually range in diameter from 2 to 10 ft and are used for flow rates up to 300 gpm. 90 0 5 90 33 7 1135 69 0 0408 d g d v b n d3 2 90 s g g n where bk ht 3 2 d b v b design 1 3v v b backwash ra e m3 m2.
