Operating and developing water quality monitoring systems to ensure the safety of water supply

Summary

In 2006 a system of water supply safety management was introduced at the SUE «Vodokanal of St. Petersburg» facilities. The system includes: water sources biological monitoring stations operating on the basis of variational crayfish pulse metering; automatic stations of continuous environmental monitoring; equipment system for detecting accidental oil spills in the Neva River water area; carrying out semiquatitative rapid tests of toxic substances; emergency sampling and analyzing water samples in case of toxic pollution hazard; systems of dozing powdered sorbents to remove water pollutants. To ensure continuous automatic monitoring, timely detection and identification of toxic substances a set of remote optical loggers and fluorimetrical flow-through instruments is used. The automatic plant for preparing and dozing powdered activated carbon includes: a big-bag emptying unit, a unit for activated carbon storing and pumping with the help of a compressor and an injector for dry product; a unit for sorbent preparing and dozing. Introducing the principle of timely detection and identification of toxic substances in water intakes, particularly with the use of online monitoring, allowed improving the responsiveness to the changes in the incoming water quality and ensuring the safety of the municipal water supply.

Water purification with the use of granulated activated carbon at the Southern Waterworks

Summary

The results of multi-year studies show that the water quality of the Neva River is deteriorating in relation to organoleptic properties. To ensure high quality drinking water the advanced water treatment technologies including coagulation, sedimentation, oxidation and adsorption were introduced at the K-6 filter block of the Southern Waterworks. Chemviron Carbon granulated activated carbon was used as sorption medium. It is shown that the use of additional carbon medium at the final stage in the sand filters increases significantly the efficiency of treatment. Sampling units were designed, sampling techniques were developed, and samples of the carbon and water from the filtering sorption medium were taken. By analyzing iodine number and sorption activity for methylene blue of activated carbon and permanganate oxidizability of water the life durability of carbon was determined which under the given operation conditions was 3–3.5 years. The perspectivenes of high-temperature carbon reactivation is shown. Herewith the technical-and-economic assessment of the reactivation cost is 50–60% of the new carbon cost.

The efficiency of using aluminium polyoxychlorides in natural water purification

Summary

SUE «Vodokanal of St. Petersburg» has been continuously upgrading water treatment technologies with the aim of improving the quality of water services. The results of laboratory, pilot and industrial approbations provided for the data on the use of more than 160 samples of coagulants based on the salts of different polyvalent metals. Among them are aluminium-, iron-, and titanium-based coagulants and also their composite compounds. Investigating more than 50 samples of aluminium oxychloride produced both by local and foreign manufacturers showed that for such special water source as the Neva River the use of chemicals of low and medium base strength in the processes proceeding in contact clarifiers is most preferable. The use of aliminium oxychloride did not result in sharp decrease of alkalinity or pH at the increased coagulant dosages. The residual alkaline reserve in water allows introducing higher chemical dosages which results in improving the efficiency of the first water treatment stage at low temperatures of the water source (less than 4 °С) and reducing filter cycle. SUE «Vodokanal of St. Petersburg» has adopted the concept of using the range of coagulants during different year seasons.
