KARADUVAR WASTEWATER PURIFICATION PLANT. MERSİN.
E N D
Karaduvar Wastewater Purification Plant is designed for purification of the wastewater from carbon, nitrogen and phosphorus. Also the waste water sludge is purified and dewatered. During this process biogas is generated and it is used for the plant’s electricity need
Karaduvar Wastewater Purification Plant after-bay water fits the European Union Standards.
INTAKE STRUCTURE AND METAL GRATES Wastewater passes through the metal grates and reaches the entrance. Here it is measured for conductivity, temperature, pH-value, turbidity and oxygen. At the entrance gate automatically samples are taken and income parameters are monitored.
GRIT AND OIL CATCHER The wastewater is then taken to grit and oil cathcher. Sand and other particles are priticipitated. Oil and otehr floating particles are offtaken by being swept away using air pressure.
PRE SETTLING TANKS There are 5 tanks. Organic and inorganic particles are separated with gravity flow. Pre settling tanks are rectangular shaped and they have catena type scrapers. These scrapers collect the settled sludge and the sludge is pumped to a tank with the help of reverse flow.
CHEMICAL PHOSPHORUS PURIFICATION UNIT In winter when bacteria action is low, phosphorus purification, which can’t be done via phosphorus purification tanks, iis done via chemical phosphorus purification unit.
There are 8 tanks. Each tank consists of 2 sections; anoxic and oxic. 5 Turbo blower blows oxygen to the wastewater in the airing tanks . It is washed and then taken to the last settlement tanks. AIRING TANKS
RETURN SLUDGE PUMPING STATION To stabilize the bacteria concentration in the airing tanks, some of the sludge is return pumped. Extra sludge is goes through mechanical condensation and sent to digesters for gas production.
SETTLING POOLS In this unit, activated sludge in the airing pools is separated from the wastewater via gravity. Then the purified wastewater realesed through the pumps and pipes into the sea.
SLUDGE DIGESTERS Digesters are used for fermentation of bacterias and organic substances oxygen free platform. During anaerobic digestion process methane is produced.
GASBAG Biogas, produced during digestion, is stored in the gasbag.
FLARE Extra gas in the digester and gasbag is ignited in a controlled way to be sent out of the unit
SLUDGE DEWATERING UNIT In this unit extra sludge is dewatered via cationic polyelectrolyte. (%23-27 dry substance)
SOLAR DEWATERING Dewatered sludge is dried via solar energy (%80 dry substance)
OPERATION BUILDING Operation building consists of; a mechanical section, a lounge, an atelier, a refectory, a sickroom, a lab and scada control units.
SCADA In the control center there 3 computers connected to the Scada system. Thanks to Scada System, all the equipments in the plant are automatically monitored, recorded and operated.
WASTEWATER ANALYSIS LAB There is a lab in the operation building. Analysis are made to test the characteristic of the waste water before and after the purification process.
