Spiral tube flocculation for drinking water treatment plants

Abstract

Almost all water treatment plants for either surface raw water or water from reservoirs needs to have some kind of a system to eliminate time required for particles to settle down in the settling tanks (This occurs by increase turbidity particle size). A coagulant to be added and a flocculation’s system to inshore a good and homogenous distribution of chemicals to form up the correct size of particles to settled within the settling tanks. In water treatment plants many types of clary- flocculates are used either the mechanicals paddle or hydraulic jumps of steam water or using the spiral tubes (As on this study). In addition, a Jar Test should be used to assess the suitability of flocculation treatment for a given raw water. Unfortunately, even Jar Test suffers from a number of disadvantages. a number of study for Spiral Flocculate, has been shown I claimed to be a better method for continuous assessment of flocculation. Within multimedia sands and a spiral flocculate’s. Constant flow (generated from a tank with spill way to ensure a constant head all through the test cycles, results are recorded, and a number of remarks and suggestions are produced. This study will make use of a number of laboratory tests on a small model of treatment plants made for this purpose consist mainly of a gravity filter compares the performance of Spiral Flocculate The experiments conducted reveal that the Spiral Flocculate has a better effective energy. Even that this method need more future study and theoretical equations for the developing of chain flocs are needed. However, the size of flocs in Spiral Flocculate seems to be overestimated relative to the real flocculate and coagulations. Purpose: A continuous need for improving water treatment techniques allows for new technologies for obtaining adequate water, both in terms of quality and quantity. In order to obtain an efficient, rapid and low-cost clarification system, this study proposes the use of spired coiled tubes as a coagulation-flocculation reactor to evaluate the proposed clarification system, a number of experimental test where generated and a pumped kaolin with controlled quantities are pumped to city water and used in this study. Water with controlled head is used all the time and records are generated for the evaluation.
