OPERATIONAL IMPROVEMENTS<\/strong><\/h3>\n<\/div>


\nAdd nanobubbles to your water treatment!<\/strong><\/p>\n<\/div>

Primary treatments, also known as physicochemical treatments, are those that mainly remove suspended solids present in the medium.<\/p>\n<\/div>

The main processes that can be included in this treatment are the following: sedimentation, flotation, coagulation – flocculation and filtration.<\/p>\n

Nanobubbles generate a striking physical-chemical interaction in the medium in which they are found, making it possible to obtain operational improvements:<\/p>\n

\u2022 Increased removal of suspended solids and organic loading<\/strong>
\n\u2022 Reduction of chemicals used<\/strong> (coagulant and flocculant)
\n\u2022 Buffer effect<\/strong> on pH maintenance<\/p>\n<\/div>

Methodology<\/strong><\/h3>\n<\/div>

We incorporate DAF Dissolve Air Flotation equipment, settlers, equalizers or other equipment in which the effect of nanobubbles is useful.<\/p>\n

Our installation can be both online and parallel to the existing primary treatment, without the need for a major intervention. We can work under different conditions, in both small and large streams, liquid waste from different types of industries and\/or with high variation of input parameters.<\/p>\n

The type of installation and operation of our technology is subject to the need of the client in conjunction with our panel of professionals, delivering a customized solution.<\/p>\n

How nanobubbles work<\/strong><\/h3>\n<\/div>
    \n
  • Coagulant\/flocculant effect (separates and joints): <\/strong>Nanobubbles have a surface charge, which is measured by one of their main properties, the zeta potential<\/strong>. Through this electrical interaction, the nanobubble interacts with the particles suspended in the medium, attracting them (destabilizing them – coagulating effect) and then generating a particle with greater weight that gradually becomes larger (flocculant effect). This interaction makes it possible to avoid to some extent the amount of chemicals used.<\/li>\n
  • Reduction of organic load and suspended solids:<\/strong> Due to its coagulating\/flocculant effect and its small size<\/strong> , an even greater removal is achieved, as it interacts nanometrically with the particles to remove them.<\/li>\n<\/ul>\n<\/div>
