disinfection – chlorination, where man determined and manually disinfection – chlorination, where man determined and manually controlled chlorine residual in the water, a conclusion has been made controlled chlorine residual in the water, a conclusion has been made that this way of disinfection does not provide constant water quality, i.e. that this way of disinfection does not provide constant water quality, i.e. the residual chlorine varies as varies a man’s error.the residual chlorine varies as varies a man’s error.

We found out that human factor seriously influences quality and rhythm of We found out that human factor seriously influences quality and rhythm of chlorination which cannot be proved unless it leads to outrage. So we have chlorination which cannot be proved unless it leads to outrage. So we have been developing the automatic dosing system with automatic regulation within been developing the automatic dosing system with automatic regulation within the admissible ranges and storing of all data and chlorination values for a long the admissible ranges and storing of all data and chlorination values for a long time.time.

To solve this problem we developed an Automatic Dosing System ADS, To solve this problem we developed an Automatic Dosing System ADS, that completely satisfies all requirements for high – quality and reliable that completely satisfies all requirements for high – quality and reliable drinking water chlorination in all types of aqueducts.drinking water chlorination in all types of aqueducts.

CHLORINATION CONTROLLED CHLORINATION CONTROLLED BY WATER FLOWBY WATER FLOW

Chlorination controlled by the water flow is used when inlet water Chlorination controlled by the water flow is used when inlet water biochemical characteristics are stable and only the water flow is biochemical characteristics are stable and only the water flow is changing in the time. Usually it is used for “Basic chlorination” when changing in the time. Usually it is used for “Basic chlorination” when raw water comes from different water sources and springs and raw water comes from different water sources and springs and production is sometimes lower, sometimes higher in accordance with production is sometimes lower, sometimes higher in accordance with needs. When chlorine quantity necessary to achieve certain residual needs. When chlorine quantity necessary to achieve certain residual for a unit of water is clear, then chlorine dosage is increased or for a unit of water is clear, then chlorine dosage is increased or decreased proportionally according to the water flow change.decreased proportionally according to the water flow change.

Basic chlorination – we assume that water is “raw” and a definite Basic chlorination – we assume that water is “raw” and a definite dosage of chlorine will certainly be used for the biochemical process in dosage of chlorine will certainly be used for the biochemical process in that water. The dosage of chlorine is called “chlorine need” or “chlorine that water. The dosage of chlorine is called “chlorine need” or “chlorine number”. It is the quantity (mg/l) which will be certainly used, and the number”. It is the quantity (mg/l) which will be certainly used, and the residual is measured and registered as uncombined chlorine. residual is measured and registered as uncombined chlorine.

CHLORINATION CONTROLLED CHLORINATION CONTROLLED BY RESIDUALBY RESIDUAL

Chlorination controlled by the residual chlorine is used when raw water flow Chlorination controlled by the residual chlorine is used when raw water flow fluctuations are not too big and when these changes are linear and that way fluctuations are not too big and when these changes are linear and that way only the quality (biochemical characteristic of water) is changed. Usually it is only the quality (biochemical characteristic of water) is changed. Usually it is used for “Corrective chlorination”, when raw water comes from an aqueduct used for “Corrective chlorination”, when raw water comes from an aqueduct prepared and partially treated with chlorine. In small systems this type of prepared and partially treated with chlorine. In small systems this type of chlorination is used as a basic and only type of chlorination.chlorination is used as a basic and only type of chlorination.

Corrective chlorination – in general chlorine treated water has a variable Corrective chlorination – in general chlorine treated water has a variable biochemical composition, so sometimes a bigger quantity of chlorine is used biochemical composition, so sometimes a bigger quantity of chlorine is used for water primary disinfection and sometimes – less. The residual chlorine is for water primary disinfection and sometimes – less. The residual chlorine is kept at the specified level by corrective chlorination system. Corrective kept at the specified level by corrective chlorination system. Corrective chlorination means that water has already been chlorine treated by basic chlorination means that water has already been chlorine treated by basic chlorination system and according to its biochemical composition it is chlorination system and according to its biochemical composition it is necessary to add a definite quantity of chlorine so that residual values are at necessary to add a definite quantity of chlorine so that residual values are at a level defined by the Law.a level defined by the Law.
