OEM/ODM Activated Carbon Block Filters for Chlorine Reduction

Activated Carbon Block Filters for Chlorine Reduction

-- Steady & Reliable Manufacturer --

Introduction to Activated Carbon Block Filters

Activated Carbon Block (ACB) filters are the most effective and widely used solution for improving the aesthetic quality of drinking water. They are engineered by compressing fine particles of activated carbon (often derived from coconut shell or coal) into a solid, uniformly porous block. This process provides a highly effective dual-action filtration: Adsorption (removing chemicals like chlorine, VOCs, and herbicides via chemical bonding) and Mechanical Filtration (removing fine sediment and particulates).

At Ningbo Yaorui Water Purification Technology Co., LTD., we specialize in manufacturing high-performance ACB cartridges. Our 15 years of expertise ensures we control the key factors: the Iodine Number (measuring the carbon's adsorption capacity) and the pore size distribution (determining the filter's micron rating). By using advanced techniques, we achieve high-flow rates without sacrificing the necessary contact time for superior chlorine reduction—the primary consumer complaint with municipal water.

We offer ACB filters in all standard dimensions (10" x 2.5",20" x 4.5", etc.) and micron ratings (0.5 to 10 micron), suitable for residential POU, POE, and light commercial applications. We are a key supplier for international distributors and OEMs who rely on us for consistent, high-volume production of cartridges that deliver guaranteed aesthetic improvement, providing flawless quality and operational reliability for their systems globally.

The Iodine Number is the critical factor for chlorine reduction capacity; we use high-grade carbon sources to ensure superior adsorption efficiency. The Micron Rating is key—ACB filters at 0.5 micron can also remove certain cysts and fine particulates, offering a health benefit alongside the aesthetic improvement. Our manufacturing technique ensures the carbon powder is compressed into a solid block with uniform density, preventing channeling (where water bypasses the media). We provide various end-cap configurations to ensure compatibility with all global housing standards. Our commitment to NSF Standard 42 compliance (for aesthetic claims) guarantees that our ACB filters deliver reliable, high-capacity chlorine reduction, which is vital for consumer satisfaction and for our international trade partners.

Core Advantages of Our ACB Filters

  • Simultaneous Dual-Action Filtration: ACB filters offer superior performance over GAC (Granular Activated Carbon) by combining chemical adsorption (for chlorine/VOCs) with mechanical filtration (for particulates) in a single cartridge, simplifying system design and maintenance.

  • High Surface Area and Contact Time: The compressed block structure maximizes the amount of activated carbon the water contacts, ensuring highly effective removal of contaminants and extending the filter's service life compared to loose media filters.

  • Elimination of Channeling: The solid block design prevents water from creating preferential pathways (channeling), a common failure point in poorly packed GAC filters, ensuring 100% media utilization and consistent performance over the filter's life.

  • Competitive Pricing and Customization: Our large-scale manufacturing capacity allows us to offer premium, high-Iodine-Number carbon blocks at highly competitive factory-direct pricing, with full customization options for micron rating, carbon type, and end-cap specifications for OEM clients.

  • Protection of Downstream Equipment: Serving as an effective pre-filter, the ACB protects expensive, sensitive equipment like RO membranes and water softener resin beds from chemical and particulate damage, lowering total cost of ownership.

These core advantages establish our ACB filters as a reliable, high-performance choice for international trade.

Essential Applications for Carbon Block Filters

ACB filters are ubiquitous in water treatment, serving as the primary stage for chemical and aesthetic removal in many systems.

  • Whole House Chlorine Reduction: Large (Big Blue) ACB cartridges are installed at the Point-of-Entry (POE) to treat all household water, eliminating chlorine and improving air quality during showering.

  • Under Sink Drinking Water: Used in multi-stage POU systems to provide superior-tasting water for consumption and cooking, often certified to reduce specific contaminants like lead.

  • Reverse Osmosis (RO) Pre-Filtration: Mandatory pre-filter to remove chlorine before the water reaches the RO membrane, as chlorine rapidly destroys the membrane's Thin Film Composite (TFC) material.

  • Commercial Food and Beverage: Essential for restaurants, coffee shops, and breweries to ensure the quality and consistency of their final products by removing compounds that affect taste.

  • Refrigerator and Ice Maker Filters: Used in compact sizes to provide the necessary taste and odor improvement for appliances that dispense water or make ice.

Their versatility makes ACB filters one of our highest-volume export products worldwide.

Payment and Shipping for International Orders

We are committed to providing seamless and competitive logistics solutions for our international clientele. Located in the strategically important Ningbo Seaport City, we maximize efficiency and minimize shipping costs for global exports.

  • Payment Terms: We typically accept Telegraphic Transfer (T/T) as the primary payment method. For established partners with a history of orders, we may offer negotiable terms such as Letter of Credit (L/C) at sight or a deposit followed by balance payment upon Bill of Lading (B/L) copy. Minimum Order Quantities (MOQ) apply for OEM and custom manufacturing to ensure efficiency.

  • Shipping Logistics: Our proximity to Ningbo Sea Port allows for efficient consolidation and dispatch of both Full Container Load (FCL) and Less than Container Load (LCL) shipments. We offer multiple Incoterms options, including FOB Ningbo and CIF to major international ports in the USA, Canada, Australia, and Europe. Sea freight is the standard method for volume shipments.

  • Lead Time: Standard lead time for production and quality control checks for Activated Carbon Block cartridges is generally 35-45 days after deposit, due to the critical carbon sintering and curing process.

  • Documentation: We provide comprehensive export documentation, including Commercial Invoice, Packing List, Bill of Lading, and Certificates of Origin as required. Detailed carbon performance data (e.g., Iodine Number, Chlorine Reduction Rate) is supplied for quality assurance.

We ensure operational reliability in logistics, guaranteeing your high-volume carbon blocks arrive securely and ready for distribution.

Frequently Asked Questions (FAQs)

  • Q: What is the main difference between GAC and Carbon Block filters?

  • A: GAC (Granular Activated Carbon) contains loose granules and primarily offers adsorption, but is prone to channeling. Carbon Block compresses the granules into a rigid structure, eliminating channeling, combining adsorption with mechanical filtration, and typically offering superior performance and fine particle removal.

  • Q: Do I need a sediment pre-filter before a Carbon Block filter?

  • A: Yes. Although carbon blocks filter particulates, they are expensive. A separate, inexpensive sediment pre-filter (e.g., 5 or 20 micron) installed before the carbon block will extend the lifespan of the carbon by preventing it from clogging prematurely with larger debris.

  • Q: Can Carbon Block filters remove lead?

  • A: High-quality carbon block filters with a very fine micron rating (0.5 micron) can effectively reduce lead by both adsorption and mechanical filtration. Products making health claims like lead reduction must be specifically certified (e.g., NSF 53) and typically use specialized media blended into the block.

  • Q: How can I tell when the carbon block needs replacement?

  • A: The primary indicator for replacement is the return of the water's original chlorine taste and odor. If the filter is also acting as a sediment filter, a significant drop in water pressure is also a strong sign that the filter is clogged and requires replacement.
