Abiran Co.
Iran,تهران,خیابان دکتر بهشتی- خیابان شهید سرافراز- خیابان 7- پلاک یک-طبقه 7- واحد 74 و 73-کدپستی: 15876ABIRAN CO. has been established since 1977 in Iran as private joint stock company.
ABIRAN CO. has participated seriously in many water and wastewater project in Iran. Up to now the company has performed more than 52 water and wastewater projects.
The main activities of the company are:
§ Wastewater treatment
§ Wastewater treatment (municipal and industrial)
§ Water desalination
§ Large pump stations
Another major activity of the company is manufacturing of mechanical equipment required by the water and wastewater treatment plant. In 1993 ABIRAN CO. singed a cooperation agreement with EUROMAC Co. in Italy.
Which led ABIRAN CO. to be a license of EUROMAC in manufacturing of various devices and components of water and wastewater treatment plants, such as chain and rotational scrapers for settling tanks, mechanical bar screen, flocculators and surface aerators and etc.
Due to an intelligent planning and collaborative work team, ABIRAN CO. now is a well-known establishment in the field of water and wastewater treatment and is one of the most reliable contractors in Iran
A. The oxygen transfer values given above is obtained in
standard conditions defined as
pure water, in absence of oxygen
at 20 C with atmospheric pressure
in optimum tank geometry and mixing conditions.
Due to the many facts that influence this test kindly refer to our
office for proper sizing of aerator
and tank for single applications.
B. Within the operation range of workin~ suggested for each power I oxygen transfer efficiency Kg °iKWH remain constant.
Power absorbed and hen~ total O transfer can be varied usually with OL special type of baseplate.
C. Rotor is made of carbon steel sheet I it is sand blasted to
SA 2.5 then coated by epoxy laver of 200 micron thickness.

Rotor: Rotor is in fiberglass of monolithic construction, corrosion resistant internally reinforced with a steel structure and completely filed with closed cell polyurethane foam. Rotor is floating and this neutralizes downwards-dynamic thrust. In this way a longer life is assured for gearbox bearings, Corrosion in any type of effluent also visually not exist ant and no maintenance over the years is required. The inclination of the blades (integral part of the rotor) and rotor-curved profile optimize the pumping rate as well as oxygen transfer.
Motor: First class make, LP 55 protected motor for continuous outdoor operation is fitted. It can be suited to any local electric feed characteristics (voltage, cps) and for any type of environments.
Dual polarity as continuons variable speed motors is available on option.
Gearbox: First class make, precision built gearboxes to suit any particular requirement of the customer are available. Special care is being taken on the service factor, bearing life, materials etc. to ensure a trouble free, and long lasting life to cope with rotor characteristics.
Oxygen transfer efficiency: giants. It constituted galleggiantir The oxygen transfer values given in the data sheet is obtained, 6 standard conditions defined as pure water, in absence of oxygen, at 200 C with atmospheric pressure in optimum tank geometry and mixing conditions. Due to the many facts that in fluency this test kindly refer to our office for proper sizing of aerator and tank for single applications.
Power absorbed variation: Within the operation range of working, suggested for each power, oxygen transfer efficiency Kg 02/ KWH remains constant. Power absorbed and hence'total02 transfer can be varied Wally with our special type of base plate and/or with telescoping gearbox, option
