Case Studies

Textile washing plant at Doddaballapur Apparel Park

We have carried out trials of our product – Poly Sulpha Sponge – on textile washed effluent water, at the textile washing unit at Doddaballapur Apparel Park.

  • The effluent was collected at the discharge point and loaded in the extended aeration tank which was filled with Poly Sulpha Sponge at 20mg/liter dosage.
  • The aeration was provided to the aeration tank through a diffused aeration mechanism for 8 hours.
  • After 8 hours of extended aeration, the permeate was transferred to the settling tank to allow any suspended solids to settle down at the bottom. The water is then passed through the pressure sand bed filter.
  • After this procedure, the permeate is measured for BOD and COD to ensure that it meets the pollution control board norms and that the water is totally odor free.
  • The same trials were conducted by CLRI and the results matched with the trials conducted on site.
Domestic Sewage water treatment at SOG colony, Davangere

The operations were conducted under the able guidance of the Executives of the Davangere Municipal Corporation for 7 days and the results were indeed encouraging and consistent.

  • The sewage in the SOG colony, in Davangere, is connected to the main drain through the open drainage system. The sewage water is collected from the main drain chamber and transferred to the extended aeration tank, loaded with Poly Sulpha Sponge.
  • The sewage water is then aerated with a diffused aeration mechanism for a duration of 8 hours and the permeate is taken to the suspended solids settling tank
  • The water is further passed through the pressure sand bed filter and tested to meet the stipulated norms of the pollution control board.



Sewage water at GM Institute of Technology in Davangere

As per the KSPCB directions in presence of the Environmental Department of GMIT  We have taken the trials 100 KLD STP Plant.

Poly Sulpha Sponge added Dosage @20 mg/l in the aeration tank and provided 8 hours Aeration & then allowed for 2 hours settling in the Secondary Settling Tank. The Overflow Water from Secondary Settling tank is collected into the Filter feed tank, where chlorine is added for disinfection. The Water from Filter Feed tank is pumped into the Pressure sand Filter (PSF) for the removal residual Suspended Solids. The treated water from PSF is taken into the Activated Carbon Filter (ACF) for the removal of excess Chlorine& Odour. The final treated water from Activated Carbon Filter is free from odour & reduction of COD, BOD levels about 75-85 % .

Madura Garments

Aditya  Birla group of Garments Industries at Bangalore two units one from Madura Garments,Anekal and English unit,Bannerghatta Road Bangalore

We have supplied the chemical for the ETP treatment for the both the units: We have treated Raw water with PSS in the 50 KLD plant,By adding PSS @ 20 mg/litre after treatment, out let water is free from Odour, the substantially reduction in the COD, BOD and Hydrogen sulphide.

Devi Sea Foods

Devi sea foods is located at Singarayana Konda, A.P. The Prawn Export Company has issues of Odour in the entire plant, and with their approach, we supplied PSS to treat the ETP water.

After PSS treatment for five days for 200 KLD plant, they found reduction in the Hydrogen Sulphide and sludge was settled in the aeration tank itself. They were happy about the reduction of Odour in the surrounding of the unit.


PSS dosage in the Aeration Tank

Ranitec Tannery units, Tamil Nadu

Ranitec is a CETP plant having capacity of 5 MLD with two aeration tank of capacity 2.5 MLD each.We have treated the plant with PSS in the primery aertion tank daily @20mg/litre. After treatment for 10 days, we checked the required parameters.

The plant Officials were satisfied regarding the Odour reduction surrounding the plant and tested the five days air monitoring to test the contamination of Hydrogen sulphide and results are very much encouraging,testing report is enclosed below.

Amburtec Tannery Unit, Tamil nadu:

Amburtech 2 MLD ETP plant set down was taken for the removal of sludge which is accumulated in the Equalisation and aeration tank about 50% to the capacity of the volume. The plant manager approached us on how to handle the sludge which contains heavy Hydrogen sulphide. We treated the entire plant with 1000 kg of Sulpha Sponge for two days , and there was a drastic reduction of  hydrogen sulphide tested by Draggers gun. Before treatment, it was more than 250 ppm and after our treatment it came to 20 to 30 ppm. With this condition, workers started the de- silting work.

Himatsinca Lenin, Hassan

Himathsinga textile factory at Hasan had a Odour issue from ETP sludge.

They approached us through the KSPCB reference. They had total 50 to 60 tonnes of sludge is accumulated. After our product Sulpha sponge treated the sludge Odour is reduced up to the satisfaction level of the staff and worker in the factory.
