Besides the benefits Achieved Tremendous Socio - Economic , Environmental and industry development issues need urgent resolution , đó polluted industrial Wastewater Wastewater treatment and is a top of the Concerns . One of the components of the waste water is seafood processing industry Wastewater containing high concentrations of salt . Compared bacteria adapt and Conditions of Wastewater thực in high salt concentrations in any way ?
 
Types of microbiology , BFL 5100HP products , have the ability to adapt to high salt concentrations by 10% in seafood processing wastewater
BFL 5100HP micro-biological products ALIVE WATER CONDITIONS IN SEAFOOD PROCESSING INDUSTRY WITH 10 % higher salt
 
Seafood processing industry is one industry that has been developed in the southern region . In addition to the benefits achieved tremendous socio- economic , industry development and environmental issues urgent need to address , in which polluted wastewater and industrial wastewater treatment is a of the top concerns .
 
One of the components of the waste water industry 's seafood processing wastewater containing very high salt content . So microbial adaptation and operation of wastewater conditions of high salt concentrations somehow ?
 
1 . Characterization and composition of seafood processing wastewater .
Processing technology of this industry is quite diverse depending on the item and material characteristics following products : frozen seafood , dried seafood , .... . Due to the richness and diversity of raw materials and component products to the nature of wastewater and industrial processed seafood is also very diverse and complex .
 
In the technological process of processing aquatic products , mainly waste water generated from the wash stage and process materials , process boiled steamed , pickled seafood process .
 
In wastewater containing many pieces of meat and seafood intestine , the biodegradable debris causing the foul smell . Wastewater also often present the kind of fish scales and fish oil . Industrial wastewater seafood processing organic contamination level is high , is composed mainly of protein and beo.Trong wastewater containing substances such as carbohydrates , protein , fat ... when discharged into water will degrade the dissolved oxygen concentration in water by microorganisms use oxygen to decompose organic matter .
 
The suspended solids make the water cloudy or colored , it limits the depth of water layer is light shining down , affecting photosynthesis of algae , moss ...
 
The nutrients ( N , P ) with high concentrations cause water eutrophication , algae grow degrade water quality . The microorganisms especially bacteria and helminth eggs in water pollution source is special .
 
Also of wastewater contains very high concentrations of salt . Waste water with high salt content such as bacterial cells participate in the wastewater treatment process is inhibited , dehydration due to osmotic pressure leads to reduced processing performance .
 
So apart from the problem of pollution of organic matter , a matter of special need attention before setting up a system to control pollution is the waste of processing seafood contain high levels of salt ( Na + , Cl - , SO42 - ) is very high , making it difficult to handle .
 
Table 1 : Data show levels of sewage pollution from seafood processing industry :
 
No. Parameters Unit Value
1 pH 6-8
2 COD mg / L from 1500 to 2800
3 BOD mg / L from 1000 to 1800
4 SS mg / L 388-452
Grease Unit 5 mg / L 150-250
Total nitrogen 6 mg / L 120-160
7 total Phosphorus mg / L 6-10
 
Table 2 : Composition of waste water processing plants dried salted fish .
 
Parameter Unit Place concentration
Other wastewater brine tank
COD mg / L 873 5250

SS mg / L 371 119
pH 6.17 6.77
Cl -

SO42 -
mg / L 26.8 10.01
N total mg / L 1,240 164
P total mg / L 4.72 5.25
 
With the data in Table 2 show that the processing of dried salted fish produce a wastewater containing high salt concentrations , from 17 to 46 mg / L.
 
2 . The most common problems encountered in wastewater treatment systems processing seafood .
 * Industrial wastewater seafood processing component mainly protein and fats , organic contamination in high level reduces the concentration of dissolved oxygen ( DO ) in the water .
* The suspended solids make the water cloudy or colored , it limits the depth of water layer is light shining down , affecting photosynthesis of algae , moss .... Also affecting the treatment works .
* The nutrients ( N , P ) with high concentrations cause water eutrophication , algae grow degrade water quality .
* The microorganisms especially bacteria and helminth eggs in water pollution source is special .
* Waste water contains very high concentrations of salt . Waste water with high salt content so will cause the bacterial cells participate in the wastewater treatment process is inhibited , dehydration due to osmotic pressure leads to reduced processing performance .
 
3 . The typical product applications in the breakdown of process wastewater treatment system processing seafood .
* Mud much balance in the aeration tank . Products to help troubleshoot as : 5100HP BFL , BFL 5200VP , BFL 5050BC .
* Microbial biomass in an anaerobic UASB unsatisfactory handling : BFL 4400AN .
* Oil is found in animal fats settling tank and aeration tank : 5100HPG BFL , BFL 5200VP .
* Floating scum and more surface-active substances in the air tank , settling tank , the aeration tank : 5200VP BFL , BFL 5600SS .
* Bad smell in the settling tank , the aeration tank : 5200VP BFL , BFL 5700SO .
* The odor may stem from solids such as solid waste , sludge from the plant ... The liquid product can handle odors on surfaces like : BFL ODOUR Clean , Freshen Free Novozymes .
* In the seafood processing industry , waste water salinity prone inhibit the aeration tank . According to the Manufacturer's empirical micro Biofuture had a 5100HP BFL product category is likely microbial activities and adaptations in salinity in wastewater aquaculture is 10 % .
 
4 . Conclusion:
Seafood processing wastewater containing high salt content , BFL 5100HP microorganisms capable of operating at 10 % salinity .
