Sedimentation is a simple, low cost pre-treatment technology to reduce settable solids and some microbes from water under the influence of gravity prior to application of other purification methods. Therefore, the surface area available for sedimentation can be extended quite considerably by superimposing a large number of water/sludge separation cells on top of the structure’s height. (function() { var s = document.getElementsByTagName('script')[0]; 22 Thus the weight of suspended particles can be increased. The method selected to produced Demineralized water depends on the quality of the influent water , the required quality of influent water , the availability of the resources such as regenerant chemicals , and waste water treatment and disposal requirement . When no ions are left to take the place of the contaminant ions, the medium is regenerated with a suitable solution that saturates the medium with the appropriate ions . Sedimentation is a unit operation of high importance in various wastewater treatment systems. The water treatment process generally adopted depends upon the quality of raw water and quality of water derived. Removal of suspended solids by sedimentation depends on particle size and density. - 7018181379, In this process, water is kept standstill in a large settling (clarifier ). They are formed by flocculation during the sedimentation process. Dissolved-air flotation (DAF) is a method whereby bubbles are produced by the reduction of pressure in a water stream saturated with air. Basic Principle of Sedimentation. However, this action can be artificially stimulated in the water treatment process. Sedimentation is an important water treatment process for water purification. The process is also known as settlingor clarification. It is a physicalwater treatment process. The purpose of sedimentation is to remove preexisting solids, as well as the precipitates formed in coagulation and flocculation. In a sewage treatment plant, the sludge’s suitability for settling is measured using the sludge volume index. another important external treatment of water is   Demineralization process . This process is very slow. The contaminant ions during ion exchange, replaced the regenerant ions because they are preferred by the exchange medium.

The water treatment plant uses the sedimentation method to pull out unwanted particles from unclean water by filtering several layers of soil and sand, allowing specific sizes of particles to pass through. Most water treatment plants include sedimentation in their treatment processes. Demineralized water is commonly produced by one or a combination of following process. It also improves the visual qualities of the water and increases its acceptance by consumers. Due to the large amount of reagent necessary for urban water, preliminary chemical coagulation and flocculation are generally not used, remaining suspended solids being reduced by following stages of the process. Sedimentationis a treatment process in which the velocity of the water is lowered below the suspension velocity and the suspended particles settle out of the water due to gravity. Flocculate means they these small particles ( discrete particles) have a tendency to form or unite and lead to the formation of small masses. The sedimentation process can be done with help of sedimentation tanks. The particles that settle out from the suspension become sediment, and in water treatment is known as sludge. The economics of the process that that produce acceptable effluent quality must be evaluated to determine the most cost effective method for a specific application. Suspended solids that have a specific gravity similar to water remain suspended while heavier … Hope you like types of sedimentation article. Undissolved suspended solids are settled at bottom of the tank. In the sedimentation processes, much of the solids are removed by gravitational settling; particles that do not settle and remain suspended ‘carry over’ to the filtration process where they can be removed by the filters. Addition of coagulates like alum makes the settling process faster. Sedimentation tanks are used to treat wastewater since several millenniums (Chatzakis et al., 2006) [2].
