System solution facilitates water blending

Water con­di­tion­ing is a sig­nif­i­cant cost dri­ver in many sec­tors. An effi­cient process water sys­tem should there­fore use only as much treat­ed water as absolute­ly nec­es­sary. To this end, Bürk­ert Flu­id Con­trol Sys­tems has devel­oped a mod­u­lar water blend­ing solu­tion with blend­ing con­trollers that reg­u­late the blend­ing process very precisely.
This solu­tion is suit­able for basi­cal­ly all appli­ca­tions that demand a con­stant high qual­i­ty of water, e.g. phar­ma­ceu­ti­cal, food and bev­er­age indus­tries. The water blend­ing unit is also ide­al for use in indus­tri­al process­es, such as the man­u­fac­tur­ing indus­try, ener­gy pro­duc­tion and for HVAC appli­ca­tions (Heat­ing, Ven­ti­la­tion and Air Con­di­tion­ing). The blend­ing unit, fea­tur­ing two inlets for untreat­ed and treat­ed water and one out­let for blend­ed water, can be sim­ply inte­grat­ed on site into the exist­ing water sup­ply or the water treat­ment plant. It comes ful­ly wired, con­nec­tion of the mains adapter is all it takes for start-up. The sys­tem is then ful­ly oper­a­ble, since the val­ues for tar­get qual­i­ty and cor­rect quan­ti­ty ratio are fac­to­ry set for the rel­e­vant application.

Ideal blending solution for every requirement

The con­trollers oper­ate with the appro­pri­ate blend­ing prin­ci­ples accord­ing to the qual­i­ty of the untreat­ed water – con­stant or vari­able. If the qual­i­ty of the untreat­ed water is con­stant, the blend­ing con­troller oper­ates as a ‘ratio con­trol’ and ensures a con­stant mix­ing ratio. Con­verse­ly, if the qual­i­ty of the untreat­ed water is vari­able, the mix­ing ratio can be adjust­ed (qual­i­ty con­trol) in line with a mea­sured tar­get val­ue (hard­ness, con­duc­tiv­i­ty). Fur­ther, the con­troller fea­tures ana­logue and dig­i­tal inter­faces for process communication.
To meet a wide range of vary­ing require­ments, Bürk­ert has come up with a mod­u­lar design for the blend­ing units. This is addi­tion­al­ly sup­port­ed by an exten­sive prod­uct port­fo­lio of per­fect­ly bal­anced com­po­nents. All com­po­nents can be sup­plied in plas­tic, brass or stain­less steel as required. Var­i­ous sen­sors, includ­ing mag­net­ic induc­tive sen­sors, ultra­son­ic sen­sors and sen­sors based on the impeller prin­ci­ple, as well as con­trol valves with an elec­tro­mo­tive or a pneu­mat­ic actu­a­tor com­plete the range of components.
