Chlorine Tablets
Introduction
Natural water is often contaminated with a number of bacteria, algae, protozoa, worms and other organisms which can cause various diseases like cholera, amoebiosis, ziardiasis, gastro-enteritis, hepatitis etc. Effective utilization of water treatment practices have contributed to a significant reduction of these diseases and, therefore, a simple and convenient method for disinfection of drinking water has become a necessity today. Conventional methods of water treatment such as storage, coagulation, sedimentation and filtration, though this reduce the bacterial level to an extent, are not sufficient to make the water safe. Boiling of water is an age old process for the killing of living micro - organisms in water but and the process consumes scarce fuel, and is not convenient for mass scale water treatment . Modern methods for disinfecting water include use of chemicals, like chlorine and its compounds, bromine, iodine, potassium permanganate, ozone and physical methods like application of ultraviolet rays, ultrasonic waves, membrane filtration, etc.
Out of the various methods, the use of chlorine is found to be very convenient and cost effective. Chlorine can be added to water for disinfection by means of bleaching powder , chlorine tablets and chlorine liquids. But, chlorine tablets have been found to be the most convenient and cost effective method and therefore are well accepted by people, both in urban and rural area.
Rural and semi-urban people drink water from ponds, rivers or open wells which are very susceptible to bacterial contamination. The source of water in urban areas is also often contaminated with municipal or industrial waste and effluents. Poor sanitation and sewage disposal in many places also cause public health hazards. The demand for chlorine tablets for disinfection of water is, therefore, increasing day by day.
Process
Powered raw materials are weighed and mixed in specified proportions. The mixed powder is fed to a tabletting machine. The measured quantity of these tablets is filled in a plastic bag and sealed to make it air tight. These bags are then put in bottles. The bottles are then sealed, labeled and packed.
