ResinTech - Model WACMP -Cation Exchange Resin Weak Acid Macroporous H Or Na Form
ResinTech WACMP is a hydrogen form macroporous weak acid cation resin. WACMP is an exceptionally high capacity resin and can be regenerated at close to 100% acid efficiency. ResinTech WACMP has low swelling and high physical strength when compared to gel weak acid cation resins. It is intended for all hydrogen cycle dealkalizer applications, as a component resin in complex demineralizers, and for metals removal in waste treatment applications (when ordered in the sodium form). ResinTech WACMP is available in the hydrogen form or in the sodium form (when ordered as WACMP-Na).

Macroporous Structure
Gives greatly increased life in stressful applications where resin degradation due to thermal and oxidative effects is anticipated
High Regeneration Efficiency
Carboxylic functional groups yield high operating capacities and almost 100% regeneration efficiency
Superior Physical Stability
93% plus sphericity and high crush strengths together with carefully controlled particle distribution provides long life and low pressure drop
Controlled Particle Size
16 to 50 mesh size provides a low pressure drop and superior kinetics
Complies With US FDA Regulations
Conforms to paragraph 21CFR173.25 of the Food Additives Regulations of the US FDA
Dealkalizer
ResinTech WACMP (H form) removes hardness from water by neutralizing alkalinity from HCO3 to CO2. The carbon dioxide can then be removed in a degassifier. For complete removal of hardness, a strong acid cation type softener is needed. For complete conversion of HCO3 alkalinity to CO2, a hydrogen form cation may be needed.
High TDS Softening
ResinTech WACMP can be operated as a softener in the sodium cycle. Selectivity for hardness compared to sodium is between 5 and 10 times higher than conventional softening resins. Regeneration requires acid followed by caustic, salt can not be used. Sodium form weak acid resins can be used to soften high TDS waters up to approximately 50,000 ppm.
Metals Removal
ResinTech WACMP has higher selectivity for divalent transition metals as compared to hardness ions.
