Selecting the equipment for wastewater and industrial sludge dewatering
Summary
The basic process parameters when selecting dewatering equipment are as follows: capacity; water content of sludge fed for dewatering; water content of dewatered sludge; dry matter retention efficiency; suspended solids concentration in filtrate (centrate). The comparative analysis of the technologic and economic aspects of using the most popular equipment for wastewater sludge dewatering is presented. The specific features of using centrifuges, belt filter presses and screw dehydrators are considered. Screw dehydrators for wastewater sludge dewatering at small-scale treatment facilities are described.

Local Treatment of Industrial Wastewater of the Samara Tank Factory Before Discharge into City Sewerage
Summary
A flow chart of local treatment of wash water of a hot metal galvanizing line making it possible to reuse them in production is proposed. It is established that in the course of waste water treatment according to the flow chart proposed the salt content in wash water does not increase and the total volume of water consumption and wastewater disposal of the factory is reduced. A possibility of using the filter-press for water clarification at reagent treatment is proved. The technology of reverse osmosis is used for organization of recirculating water supply.
Key words

Modernization of Sewerage Treatment Facilities
Summary
The basic technical decisions and a description of the new equipment introduced at sewerage treatment facilities of the city of Novosibirsk are presented. It is told about the methods used when repairing pipelines and capacitive facilities. Modernization is carried out at all stages of treatment: at the main pumping station, mechanical and biological treatment facilities, sludge treatment facilities. Measures carried out make it possible to improve the quality of wastewater treatment, to reduce the discharge of polluting substances into the Ob. Modernization of the operating treatment facilities owing to the use of up-to-date equipment made it possible to improve the reliability of operation of the complex as a whole, to reduce the volume of sludge intended to further utilization, to reduce the negative influence on the environment and improve the city ecology.

Typical engineering solutions of a wastewater sludge
mechanical dewatering plant
Summary
An illustration of a comprehensive typical solution is presented for the construction of a wastewater sludge mechanical dewatering plant based on filter press use for wastewater treatment facilities. Choosing the method of wastewater sludge treatment has been a complicated engineering task that demands special research and experiments at simulated or operating wastewater treatment facilities. Herewith the sludge dewatering properties, dewatering equipment type and cost, as well as the technology of the subsequent sludge handling with account of sludge utilization shall be taken into consideration and specified. The advantages of new construction compared to the upgrade of the existing buildings, networks, equipment are shown. Two of the typical projects are presented – with the use of two and three filter presses. The developed engineering solutions provide for the shortened timescales of project design and cost. The typical projects have been executed with the use of advanced 3D-designing tools that provide for the visualization of the building, equipment and utility systems already at the design stage of the future wastewater sludge mechanical dewatering plant.
