Problems of design and implementation of the filtering equipment for municipal drains treatment and dehydration of water-treatment stations deposits

Abstract

The problem of municipal drains treatment and dehydration of the water-work condensed deposits is very actual in many cities of Ukraine and the NIS and needs the effective decision.
Municipal and water-work condensed deposits considered as a difficult-to-filtering suspensions, Dehydration of such deposits requires, in particular, application of the filtering equipments working under superfluous pressure, In connection with significant volume of suspensions, demanding the dehydration, for water-treatment plants are required filter- presses with
the big surface of filtering, For such tasks the application of specially designed chamber filter
- presses with vertical plates arrangement can be the most effective.
The main requirements for the design of filtering equipment for municipal drains treatment
and other industrial and municipal enterprises are:
• high productivity and compact;
• simple and reliable design;
• characterized by small duration of auxiliary operations (10-20 min on a standard size of
the filter);
• effective electrical consuming, (energy saving technology);
• equipped with effective automatic devices of filtering plates regeneration without their
dismantling from filter - press;
• equipped by plates with squeezing membranes that allows to intensify process of filtering
and it is essential to lower humidity of a filtered deposit;
• do not demands the big areas and high flights for installation, and a lot of high qualified
professionals for operation and service;
• allows to receive a deposit with humidity not above 60 %.
