PSD-MAC
purestar
As municipalities increasingly shift from free chlorine to chloramines for secondary water disinfection, standard activated carbons struggle to achieve efficient and long-lasting chloramine removal. PSD-MAC is engineered with an advanced internal surface chemistry that actively catalyzes the breakdown of chloramine molecules, rather than relying solely on physical adsorption.
This catalytic action enables PSD-MAC to deliver 2-3 times the service life of standard granular activated carbon in chloramine-heavy water streams, while maintaining stable removal efficiency over extended operation periods. The optimized pore structure also provides excellent adsorption of other common water impurities, making it a versatile solution for municipal drinking water treatment plants, residential water purification systems, and food-grade water treatment applications.

FAQ
Q1: How is PSD-MAC different from standard activated carbon for chloramine removal?
A: Standard activated carbon relies solely on physical adsorption to remove chloramines, which leads to rapid saturation and short service life. PSD-MAC uses advanced catalytic surface chemistry to actively break down chloramine molecules, providing significantly longer service life and more stable removal efficiency over time.
Q2: Is PSD-MAC suitable for residential drinking water systems?
A: Yes, PSD-MAC is designed for both municipal and residential water treatment applications. Its stable catalytic performance, neutral pH operation and high mechanical strength make it ideal for use in under-sink filters, whole-house water systems, and countertop water purifiers.
Q3: Can you provide samples before bulk order?
A: Yes, samples can be given to you. Please contact us for details. Once we charge you the sample fee, please rest assured that this will be a refund when you place a formal order.
Q4: What is your minimum order quantity (MOQ)?
A: MOQ depends on product type. Please contact us for detailed information.
Q6: How to confirm payment?
A: We accept T/T ,L/C, and other payment methods are also acceptable. Please contact us before you make payment through other payment methods. In addition, a deposit of 30-50% is feasible, and the balance shall be paid before shipment.
