Process water treatment without chemicals –
with effective use of cavitation

The Challenge

All process­es involv­ing inter­ac­tion with water are prone to the risk of patho­log­i­cal con­t­a­m­i­na­tion. Biofilm and algae growth are a fre­quent cause of increased ener­gy, main­te­nance and oper­at­ing costs, as well as con­sti­tut­ing a health haz­ard to work­ers and con­sumers and a poten­tial dan­ger to the environment.

To tack­le this prob­lem Stein­hardt GmbH and Dil­li­gence Sys­tems GmbH, a Ger­man com­pa­ny with more than thir­ty years of expe­ri­ence in the field of process water treat­ment, have joined forces to cre­ate inno­v­a­tive water purifi­ca­tion sys­tems that guar­an­tee a max­i­mum degree of hygiene and clean­li­ness with­out the addi­tion of chemicals.

The Way – Hydro-mechanical Cavitation

The Stein­hardt Dil­li­gent® Process Water Treat­ment Sys­tems make effec­tive use of cav­i­ta­tion, i.e. the implo­sion of tiny gas bub­bles in flu­ids. Our sys­tems employ the ener­gy released by the implo­sion of the gas bub­bles to elim­i­nate organ­ic mat­ter such as bac­te­ria, germs, yeasts and moulds. The microbes are mechan­i­cal­ly destroyed and then dis­posed of by nat­ur­al oxidation.

The Products
