Black Opal Group heritage
The group was established in 2010 through activated carbon manufacturing and field experience, with a reputation built on quality, innovation, service, and reliability.
Company-owned manufacturing supports tighter control over coconut shell selection, activation, sizing, testing, and final assurance before shipment.
Quality from feedstock to final carbon
Black Opal’s quality position starts with selected coconut shell raw material and continues through controlled activation, screening, washing or pH adjustment where required, packing, and final checks.
The result is an application-focused carbon range with strong hardness, surface area, attrition resistance, and product consistency across water, mining, gas, refinery, and specialty markets.
