Defluoridation

Defluoridation

Effects of Excess Concentration of Fluoride in Water  Fluoride  which is naturally in groundwater in concentrations ranging from 0.1 mg/L to 10 mg/L. The chemical originates in several minerals. As...
Water Treatment

Water Treatment

Objective of Water Treatment Objectives of water treatment are to remove the different impurities present in the raw water, to render the water safe and clean and to ensure the treated water quality meets the...
Zones of Sedimentation Basin

Zones of Sedimentation Basin

Sedimentation basins have 4 zones 1. The Inlet zone, 2. The Settling zone, 3. The Sludge zone, and 4. The Outlet zone. Each zone should provide a smooth transition between the zone before and the zone...
Pressure Filter

Pressure Filter

Pressure filter is a RSF contained under pressure in a steel tank, which may be vertical or horizontal, depending on the space available. Similar to gravity filters, the media in pressure filter is usually...
Comparison of Slow Sand Filter and Rapid Sand Filter

Comparison of Slow Sand Filter and Rapid Sand Filter

COMPARISON OF SSF AND RSF The comparison of SSF and RSF with reference to design criteria, advantages and disadvantages is summarized in the below Table Comparison of Slow Sand Filter and Rapid Sand...
Rapid Sand Filters

Rapid Sand Filters

The Rapid Sand Filter (RSF) differs from the Slow Sand Filter in a variety of ways, the most important of which are the much greater filtration rate and the ability to clean automatically using backwashing....

CHLORINATORS

CHLORINATORS

Hypochlorinators The simplest method of continuous chlorination of water supply systems for a water flow of less than 200 Lpm is by the use of a hypochlorinator. Hypochlorinators are motor driven pumps which...
Lime Softening

Lime Softening

Lime softening involves a relatively complicated series of chemical reactions. The goal of all of these reactions is to change the calcium and magnesium compounds in water into calcium carbonate and magnesium...
Electrodialysis

Electrodialysis

      Electrodialysis Electrodialysis (ED) and electro dialysis reversal (EDR) employ specially prepared by the reverse osmosis membranes which are semipermeable to ions based on their charge, and they...
