Case Study - 01
Plant : Bio-engineered Sewage treatment plant.
Location : Karunya University, Coimbatore.
Flow per day : 540 cubic meters.
Inlet BOD : 340 to 480 ppm.
Outlet BOD : 6 to 7 ppm.
Economics : Treatment cost comes to Rs. 2.40 per 1000 liters of effluent per day.
Remarks :

This whole STP was designed on the concept of bioengineering based on Bioclean STP. This plant can treat more than 540 cubic meter of sewage per day using only 9 HP of power. The outlet BOD is in the range of 4 to 6 ppm. All the treated water is being used by the farmers residing in the nearby areas on their farms for irrigation. After the Bioclean STP treatment the total coliform count has gone down by 93 % as compared to the inlet. The area used for this STP is less than 200 meters.

Case Study - 02
Plant : Bio-engineered Sewage treatment plant.
Location : Sulur Small Tank, Palladam Taluk, Coimbatore District.
Flow per day : 600 cubic meters.
Inlet BOD : 520 ppm.
Outlet BOD : 8 ppm.
Inlet Oil & Grease : 10 to 20 ppm.
Outlet Oil & Grease : Traces.
Inlet Total Coliform : 100000 MPN/100ml.
Outlet Total Coliform : 75 MPN/100ml.
Economics : Treatment cost comes to Rs. 2.30 per 1000 liters of effluent per day.
Remarks :

It is clearly evident that the pathogenic bacteria in the treated water has been reduced to almost 97 % average. The treated water has been stored in the neighbouring tanks for recharging. They also have bore wells around 300 mts. from the storage point and the water is now being used for external purpose other than drinking application. The quality of the water in the neighbouring farm wells has improved dramatically and is now being used for agricultural applications. The Cattle, Birds and other animals have started consuming the water, which was not the case before. The Panchayat also claims that the birds, which had migrated, have also come back.

Case Study - 03
Location : Restaurant in Mumbai, Maharastra.
Remarks :

Mr. Shetty the owner of the restaurant had to clean up his drainage line every third day, due to the heavy clogs of grease and oil. Before addition of Bioclean, the whole pipeline was cleaned. After Bioclean usage for the past one year he has cleaned the line only twice, because of blockages due to plastic bags .

Before Bioclean addition 10 days after Bioclean addition
21 days after Bioclean addition
