In this article, we take a look at key industries that have benefited from the Advanced ‘Immobilized Cell Reactor’ wastewater treatment technology:

1) Leather Industry:

The Advanced ‘Immobilized Cell Reactor’ technology performs at a credible level for the removal of organics estimated as BOD and COD from wastewater generated in garment leather manufacturing industry. The maintenance cost of the effluent treatment plant was reduced by $2000 per annum, through savings on electricity and chemicals. The wastewater treated using the immobilized cell reactor supported the growth of vegetative plants and aquatic bred animals.

2) Textile Industry:

The technology was applied for the treatment of wastewater discharged from textile-yarn-dyeing industry. The wastewater contains the dissolved organics classified under dyestuff, starch, EDTA, citrate etc. The immobilized cell reactor treated wastewater met the discharging standards reused within the industry or used for irrigation purposes.

3) Sago Industry:

Tapioca, the commercial crop is a source for production of starch. The potential use of starch is manifold mainly in pharmaceutical, explosives, alcohol fermentation, food industries etc. The industries are engaged in processing of raw tapioca into starch powder through peeling, crushing, washing and settling the milk of starch and drying in solar evaporation pans.

4) Chemical Industry:

The industry is engaged in manufacturing certain type of monomers that discharge only 3500 liters per day. The wastewater was of high COD in the range of 70-90 g/l. The reactor treated wastewater was expected to meet the discharging standard of Dubai municipality i.e. COD 3000 mg/l and BOD 1000 mg/l. The suggested treatment technology for the treatment of wastewater was anaerobic treatment followed by Advanced ‘Immobilized Cell Reactor’ treatment.

The anaerobic system used was anaerobic contact filter filled with polymeric material of void ratio 0.5. The reactor was of height 5.5 m and dia. 1.5 m. The anaerobically treated wastewater was treated further in immobilized Cell bioreactor of height 5 m and dia. 1 m. The treated wastewater from the reactor was able to meet the discharging standards prescribed by the regulatory agencies in Dubai.
