Description Elevate your water purification with Carbon, a premium Granular Activated Carbon (GAC) manufactured right here in South Africa. Sustainably sourced from local macadamia nut shells, this high-density media undergoes an advanced steam activation process to create a superior bimodal pore structure. Whether you are treating municipal water or complex borehole sources, Roto Carb MRS1 offers an eco-friendly, high-performance alternative to traditional coal or coconut-based carbons. Key Features & Benefits Eco-Friendly & Sustainable: Locally manufactured from renewable macadamia shells, reducing the carbon footprint of your water treatment. Superior Bimodal Filtration: A unique mix of meso- and micro-pores allows the carbon to adsorb a vast range of molecular sizes for more comprehensive cleaning. High Chemical Resistance: Effectively eliminates Chlorine, Volatile Organic Compounds (VOCs), and organic contaminants that compromise water safety. Exceptional Durability: High mechanical strength and hardness lead to lower energy backwashing and rapid bed fluidization. Certified Quality: Fully compliant with SANS 52915 (EN12915) standards for use in potable drinking water treatment. Low Ash Content: Ensures a cleaner filtration process and a high-developed internal surface area for maximum adsorption. Versatile Water Treatment Applications Carbon is engineered for versatility across residential, agricultural, and industrial sectors: General Potable Water: Improves the taste and smell of municipal drinking water. Borehole Water Purification: Reduces organic impurities common in groundwater. Specialized Systems: Ideal for aquaculture, water re-use, and agricultural irrigation.
