Industrial waste water treatment plants

Industrial water treatment is dealt with by our company in case of
biologically treatable waste water. In particular, this applies to waste water
from foodstuffs industry like dairy waste water, water from slaughterhouses,
meat processing industry plants, from sugar mills, breweries,
foodstuffs-producing plants, etc.

The design

We deal with the design of the industrial waste water treatment technologies
in fully individual manner as we take into account specific properties of the
separate industrial waste waters. If the industrial waste waters are part of
the municipal waste waters from municipalities and towns, it is necessary to
accommodate the municipal waste water treatment technology to the ratio and
effects.

The technologies

The technologies may be very diverse, not only according to the kind of
industry but also according to the particular line of production in the
establishment.

Sometimes it is possible to use the basic technology, D-N system, as for the
municipal waste waters. For some types of production (e.g. dairy works), it is
suitable to use separated regeneration of activated sludge. Frequently it is
necessary to use technology with a selector eliminate filamentous bulking of
the sludge. According to the type of water, the selector may be aerobic
(aerated) or anaerobic (mixing only). According to the nitrogen content the
selected technology either removes the nutrients (nitrification –
denitrification system, or simultaneous nitrification – denitrification
system), or doses the nutrients in case of their absence. According to the
phosphorus content, the excess phosphorus is either removed biologically or,
more frequently, by chemical precipitation by Fe salts, or dosed into the waste
water, in case of its absence.

In case of industrial waste waters it is often necessary to deal with the
waste water inlet irregularity by equalizing.

The issue of high or low pH is dealt with by neutralizing before the
biological line. With respect to the excess sludge production (may be different
from municipal waters) it is suitable to deal with the sludge disposal, as to
the stabilization of excess sludge or its dewatering and/or hygienization with
respect to its disposal or further use.

With respect to the diversity of industrial waste waters it is not possible
to describe a universal treatment method for these waters. On the contrary, the
method is individual for each case.

As it is essential to have sufficient input data for the proper
technology design, it is suitable to ask for assistance of technologists in
submitting and acquisition of data. If input data change, it is
possible to update the technology design.

Discharge limits

Discharge limits are attained according to the type of waste water and
selected technology, which is based on the requirements submitted. We endeavour
to guarantee the requested discharge limits. If the submitted limits for the
given type are unattainable or if they require extremely intensive and
expensive technologies, consultation with the customer is performed. With
respect to the knowledge of legislation, we strive for solutions viable for the
customer as well as the authorities (watercourse administrator, water right
authorities, etc.).
