• We Give Clear Solutions

We are Manufacturer, Supplier, Exporter of Bag Filters / Filtration Systems (Kobag) for ETP and STP Sludge Dewatering application. Our manufacturing unit is situated at Pune, Maharashtra, India.

This is engineered for small Effluent Treatment Plants and Sewage Treatment Plants. Come in various model catering from 1 cu.m to 6 cu.m/day of sludge flow with 1-2% consistency. The capital cost of these units is less. They are easy to use and operate. Even an unskilled single person can handle the sludge upto disposal without the need for any additional manpower. There is no need for space consuming sludge drying beds at all.

Sludge coming from clarifier is added with required chemicals and fed into the KOBAG through feeding mechanism. KOBAG is made up of specially developed hydrophobic reusable bags. They allow easy passage of treated water. But block the solid particles. After just few hours of dewatering, about 15% solids concentration is reached in the bags. Easy bag removal technique is assisted by a specially provided trolley. Bags containing sludge is carted to the natural drying area. It is further observed that just couple of days of natural drying generates sludge with more than 30-40 % solids.

Special material of the bag not only give it all the characteristics required for good filtration and solids capture but also is of reusable type. The bags after discharging sludge from them can be repeatedly used several times before needing to be disposed off



Most Economical Sludge Dewatering For SMALL ETP!!!!!

  • Sludge generated in small ETP is also small.
  • Scientific sludge separation and disposal is desirable and mandatory.
  • Statutory requirements will only get much stricter with the passage of time.
  • Conventional drying beds and filter presses are quite costly and are highly labour intensive.
  • Highly advanced belt press filters are too costly.
  • KOBAG is the ultimate answer.
  • Only one person, who is operating the ETP can handle the sludge management, without any additional manpower.
  • Conditioned sludge from the ETP is drained in the specially made Hydrophobic filter bags.
  • Clear filtrate flows out of the bag from all sides and is carried out of the unit.
  • Just few hours of operation will yield solid concentration of higher than 15%.
  • Bags are then sealed and removed from the unit with the help of the special Removing trolley.
  • The bags can further be stored in the open or under roof, for further evaporative dewatering.
  • Typically within 10-15 days of atmospheric drying, a moisture content of about 60-65% can be obtained.
  • The bags are then sent for final disposal.
  • KOBAG system come in 1 - 6 bag configurations.

  • STP plants of various industries
  • STP plants of housing / commercial complex.
