Water conditioning - Import export

Measurement and control In this sector, MPT represents the interests and products of WALCHEM Corporation in Holliston, Massachusetts (USA). WALCHEM is a leading manufacturer of sensor technology and controllers for the surface technology and for the water treatment technology, including pH-, redox and conductivity controllers as well as special controllers for the cooling-water and boiler water conditioning. Besides the measuring transducer, these controllers include also a control program, adapted to the respective application. Monitoring, alarming – control and telecontrol systems By default, WALCHEM’s WebMaster has available sensors and data amplifiers for various physical parameters. Using the integrated program the parameters can be linked to each other and to control parameters. Via telephone modem and Ethernet board the user is provided with information such as alarm messages and off-limit conditions worldwide.  Measuring and control technology for dosing liquid media in

Recovery of flexoprint dye Picture: printing dye (red); ultrafiltrate (orange); nanofiltration permeate (clear) Application: Conditioning and concentration of cardboard printing dyes (flexo print), e.g. paper bag manufacturing, corrugated board manufacturing. Conditioning of the rinse waters by ultrafiltration(UF): Recovery and recycling of dyes, separated by tonality Further conditioning of the permeate by nanofiltration(NF): Recovery of the rinse water Further conditioning of the UF-concentrate by evaporation / distillation as pre-stage for external disposal Advantages of the process: Recovery of dyes separated by tonality is possible and established Recirculation of the rinse water is possible and established Reduction of the waste water amount At existing waste water treatment plants (based on precipitation) amounts of sludge can be reduced enormously Compact and modular design Fully automized process - low personnel costs High degradation rate and efficiency (concerning CSB, Cu,

Boiler feed water The so called „Boiler feed water“ is stored in a feed water tank and continuously feeded to the boiler of a steam generator. A big quantity of feed water is needed for example in steam power plants. The boiler generates steam, which is used for heating, for chemical processes or for driving a steam turbine respectively a steam engine. The feed water is purified in a way, that all harmfull components for the boiler are removed or neutralized. Leakages and evaporation loss are compensated by additional water which is purified in the same way than boiler feed water. Very often, valuable well and potable water resources are used for the generation of process water. Environmental regulations restrict this usage of well and potable water continuously and increase the costs for this resources steadily. The conditioning of stream water to boiler feed water helps saving potable water and means cost advantages. The process of conditioning is based on ultra filtration with down
