Lewatit C 249 is supplied in a heterodisperesed particle size distribution as spherical beads in the fully swollen moist sodium form. Lewatit C 249 is prepared with a minimum amount of fines (-50 mesh particles) resulting in low pressure losses during service. Lewatit C 249 is supplied in the sodium form . Lewatit C 249 is also available in the hydrogen form,designated as Lewatit C 249.
Physical and Chemical Properties :

Lewatit® S 1567 is a new developed food grade, strongly acidic cation exchange resin with beads of uniform size (monodisperse) based an a styrene-divinylbenzene copolymer. Lewatit® S 1567 is manufactured without the use of solvent. The monodisperse beads are chemically and osmotically very stable, and they can effectively be disinfected for the drinking water processing. The optimized kinetics lead to an increased operating capacity compared to ion exchange resins with heterodisperse bead size distribution. 
Lewatit® S 1567 is especially applicable for :• Softening in special systems with regular disinfection• Softening of drinking water
Lewatit® S 1567 is adding special features to the resin bed :• High exchange flow rates during regeneration and loading• Good utilization of the total capacity• Low rinse water demand omogeneous throughput of regenerants, water and solutions; therefore a homogeneous working zone.• Nearly linear pressure drop gradient for the whole bed depth therefore operation with higher bed depth possible.

Lewatit ASB 1P is a premium grade, gel, strong base type I anion exchange resin specially suited for high purity separate or mixed bed applications if a reduction of the silica concentration is needed. The relatively open matrix of the polymer enables the use to more adequately treat waters of a higher content of organic molecules such as tannic and fulvic acids. Lewatit ASB 1P is produced on the basis of a cross-linked styrene divinylbenzene polymer. It is supplied in the form of spherical beads. Lewatit ASB 1P has high an exchange capacity combined with an excellent stability to organic fouling.It contains a minimum amount of lines( up to 50 mesh), resulting in low pressure losses. Lewatit ASB 1P is available in its chloride form. Specifications :

Lewatit® MonoPlus M 500 is a strongly basic, gelular anion exchange resin with beads of uniform size(monodisperse) based on a styrene-divinylbenzene copolymer. The monodisperse beads are chemically and osmotically highly stable. The optimized kinetics lead to an increased operating capacity compared to ion exchange resins with heterodisperse bead size distribution.
Lewatit® MonoPlus M 500 is especially applicable for :• Demineralization of water for industrial steam generation, e.g. Lewatit® WS System, Lewatit® Liftbed System or Lewatit® Rinsebed System• Polishing by a Lewatit® Multistep System in combination with Lewatit® MonoPlus S 108 Lewatit® MonoPlus M 500 is adding special features to the resin bed :• High exchange flow rates during regeneration and loading• Good utilization of the total capacity• Low rinse water demand• Homogenous throughput of regenerants, water and solutions; therefore an homogeneous working zone• Nearly linear pressure drop gradient for the whole bed depth, therefore an operation with higher bed depth possible Specifications :

Lewatit NM 60 is a highly regenerated mixed bed ion exchange resin consisting of 1:1 chemically equivalent mixture of a type 1, strong base anion exchange resin and a strong acid cation exchange resin. Lewatit NM 60 is specially treated for high conversion and low TOC to meet the most exactin standards of high purity water industry.
Lewatit NM 60 is especially suited for the applications mentioned below :• In mixed bed units for polishing after primary demineralization systems• In process industries• In electronic industries• In small industrial plants (e.g refilling of starter batteries or coolant circuits)• For the removal of radioactive waste• In demineralization systems

Industrial Water Softeners remove hardness ions from water through ion exchange, which exchanges hardness ions for more harmless ions, such as salt.
Hard water is water that has calcium and/or magnesium salts dissolved in it. The degree of hardness is directly related to the concentration of these salts. Hard water consumes soap and adversely affects washing and cleaning operations in the home and throughout industry. Hard water salts form scale in pipe lines, boilers, heat exchangers, hot water heaters, water chillers & UV shells.
