BAG DEWATERING SYSTEM
A modular system for dewatering.

For dewatering the sludge of every nature produced by treatment plants, TEKNOFANGHI proposes TEKNOBAG-DRAIMAD®. The heart of the system is the original draining bag TEKNOBAG-DRAIMAD®, which permits to reach 15-30% dry solids content after only a few hours and 50-80% of dry solids after certain storage period. The right management of this system depends upon the special module realized in stainless steel AISI 304L, projected to optimize the filling of the bags and to simplify all moving operations. To be able to satisfy all the necessities of the WWTP, TEKNOBAG-DRAIMAD® is available in various models, starting from the manual modules with 2 bags up to automatic and pressurized with 12 bags. The largest module can treat up to 20m³/day of sludge depending on its concentration.

 

TYPICAL APPLICATIONS:

  • Municipal wastewater up 4000 P.E.

  • Resorts, hotels and camping

  • Industrial wastewater

  • Chemical industry

  • Food and beverage

  • Dairy farms and slaughterhouses

  • Wineries and breweries

  • Drinking water, river and lake water

  • Mineral, ceramic, glass

DEWATERING

After a few hours operation (with the correct conditioning of the sludge with polyelectrolyte), dry solids contents of 15-30% can be achieved, depending on the nature of the sludge. The volume of dewatered sludge produced is dependent on the solid content of the feeded sludge. For example, with sludge contents of 1% dry solids, one machine can treat up to 20 m3 per day.

DRYING

After the initial dewatering stage on the machine, the bags are sealed and removed with a special bag trolley and stored in the open. During this second phase, sludge weight and volume continue to reduce, regardless of weather conditions. The special water repellent material of the bags prevents rainwater from entering, but allows dehydration of the contents by evaporation. After two months storage, a cake with minimum 50% dry solids content is achievable. If the sludge is stored for a few more months, the final result will be between 70% and 95% dry solids. As an example, 1 m³ of sludge at 1% solids content would give, after two months, a cake of at least 50% dry solids content. This would weigh only 20 Kg and represents a 50-fold reduction of the original weight.

DRAINING BAGS

The heart of the system is the draining bag, made from a special “TNT” water repellent material, very resistant and inert to: chemicals, acids, bacteria and insects. 

FLEXIBILITY

The TEKNOBAG-DRAIMAD® system are offered in about 30 different models, ranging from the small manual units, to the fully automatic and pressurised units. If it is found necessary to increase the sludge capacity of a plant where a bag-module is already installed, an additional bag-module can be added and connected using the existing flange and saving additional costs.

PRESSURIZATION OPTION

The optional pressurization facility enables the dewatering time to be decreased and increases the quantity of sludge which can be treated. This is due to the higher dry solids concentration achieved inside the bags, reducing the working time and bag consumption.
