26-11 TEHNOLOGIE DE EPURARE BIOLOGICĂ CU TUBURI POROASE ŞI TUBURI CU MEMBRANĂ ELASTICĂ PERFORATĂ ȘI DIMENSIONAREA INSTALAȚIILOR DE AERARE

TECHNOLOGY FOR WASTE WATER TREATMENT WITH
POROUS TUBE AERATORS AND ELASTIC PERFORATED
MEMBRANE TUBES OF THE BIOLOGICAL
WASTE WATER TREATMENT
The paper is to review and assess existing design procedures and provide
in-depth design information on critical features of the aeration process using Tube
aerators porous and elastic membrane tubes and key parameters affecting its
operation and performance that is typically available to the engineering community.
Since past decade, the old works started to be replaced with new technologies such
as those using tube aerators porous and elastic membrane tubes, especially for
industrial and municipal waste water treatment plants. This paper discusses the
theory, performance, design procedures, calculation and dimensioning of the
aeration using Tube aerators porous and elastic membrane tubes.
Keywords: aeration, porous tubes, tubes with elastic membrane, aeration
plants, wastewater, and wastewater treatment schemes
Cuvinte cheie: aerare, tuburi poroase, tuburi cu membrana elastică, instalații
de aerare, ape uzate, scheme de epurare

21-70 TEHNOLOGIE DE EPURARE BIOLOGICĂ CU CONTACTORI BIOLOGICI ROTATIVI ŞI DIMENSIONAREA FILTRELOR DE EPURARE BIOLOGICĂ

TECHNOLOGY FOR WASTE WATER TREATMENT WITH
ROTATING BIOLOGICAL CONTACTORS AND
DIMENSIONING OF THE BIOLOGICAL WASTE WATER
TRETMENT
The paper is to review and assess existing rotating biological contactors
(RBC) design procedures and provide in-depth design information on critical
features of the RBC process and key parameters affecting its operation and
performance than is typically available to the engineering community.
Since past decade, the old works started to be replaced with new
technologies such as rotating biological contactors (RBC), especially for small
communities. RBC is an attached – growth biological process, which consists of
a series of rotating plastic media all coated with a layer of bio film.
The bio film or slime on the media aerobically reacts with substances in a
waste stream for bio-oxidation and nitrification, or anaerobic ally react with the
substances for denitrification. This paper discusses the theory, performance,
design procedures, calculation and dimensioning of the RBC process.
