FLOATSEAL– INNOVATVE FLOATING COVER FOR WATER SURFACES! 

 

Worldwide novelty of using floating plastic covers to exclude oxygen penetration in non-aerated selectors, to increase the effectiveness of removal of nitrogene and phosphorus and to contribute to good sludge settleability. This innovative method was first published in 2014 in the volume of „AS 100 Years and Counting ”.  

 

 

 

 

 

The Karsai Pécs Co., which is member of the Karsai Holding Plc. in cooperation with the researchers of Budapest University of Technology and Economics, Faculty of Chemical Technology and Biotechnology developed this innovative solution with incremental improvements.

 

 

We have to face the problem of decreasing availability of readily biodegradable carbon source  which is highly needed for effective removal of nitrate and extra phosphorus. Oxygene penetration further deteriorate or even prevent the process of denitrification. Traditional solution to the problem is adding extra carbon or chemicals. With covering the surface of usually open selectors we create a real anoxic and anaerobic environment, where the micro-organism can remove the nitrate and extra phosphorus more effectively and a good sludge is settled.  (Jobbágy et. al. (2019) Use of floating seals to exclude oxygen penetration in non-aerated selectors, Water Science and Technology, 80 (2), pp. 357-364)

 

 

 

-         The flloat seal is designed to provide significant insulation and resist sunshine.

-         The pieces can be flexibly connected, so you can cover surface of any size and shape.

-         This continuous float seal surface strictly follows the fluctuations of the water level

-         It is flexible, lets liquid flowing in and out on the surface and below

-         Resists different weather conditions, including windstorm, rain, snow or heavy sunshine; May not sink and be blown by wind.

 

Features of a float seal:

 

-         size  :                                   400 x 400 x 50    mm

-         weight :                                 0,97 kg per unit

-         material :                               polypropylene

-         color:                                     white

 

 

Temperature:   between - 20 C and  + 46 C

 

 

Special applications:

 

-         cost-effective operation of biological wastewater treatment

-         providing real anaerobic and anoxic conditions for biological P and N removal.

-         contributing to well-settling activated sludge

-         hindering exit of unpleasant odor

 

Advantages :

-          cost-effective

-          environment friendly solution; makes chemical savings possible  

-          saving and fermenting C-source

-          decreasing the likelihood of N2O formation, being responsible for global warming and green-house effect

-          excluding snow and sudden temperature decrease

-          suitable for covering any liquid surface like reservoir, tank, pond etc.
