Carbon Block CTO Cartridge – 20 Inch Jumbo | UV Water Systems Oman

Commercial and whole-house water treatment systems in Oman treat substantially higher daily volumes than under-sink residential RO units — a restaurant might consume 2,000–5,000 litres per day across kitchen, ice machine, and beverage production; a large villa processes 1,000–3,000 litres across multiple bathrooms, kitchen, and laundry. At these flow rates and volumes, a 10-inch slim carbon block cartridge exhausts within 4–8 weeks — an unacceptably frequent replacement interval for commercial operations. The 20-inch jumbo carbon block CTO cartridge provides approximately 4× the carbon mass of the 10-inch equivalent, delivering proportionally extended service life and higher flow capacity at lower pressure drop. UV Water Systems in Muscat supplies 20-inch jumbo carbon block cartridges for commercial, whole-house, and industrial water pre-treatment systems across Oman — as standalone whole-house chlorine reduction filters and as RO pre-treatment components in commercial and industrial systems.

Commercial Carbon Block Applications in Oman

In commercial food service in Oman — the restaurants, cafes, hotel kitchens, and food production units that UV Water Systems serves across Muscat — the carbon block serves two distinct roles. Before an RO system, it protects the membrane from chlorine oxidation (the same function as in residential systems, at higher volume). In the absence of an RO system, a jumbo carbon block housing is used as a whole-building chlorine and taste/odour treatment system — typically installed on the main building water inlet to improve the taste of all water used in food preparation and beverage making without the RO system’s flow rate restrictions. For a restaurant where tap water quality affects every dish and drink, whole-house carbon block filtration is often the most practical and cost-effective improvement.

Key Features and Benefits

4× higher carbon mass than 10-inch equivalent: Double the physical length plus larger OD delivers approximately 4× the carbon adsorption capacity — extending cartridge service life to 6–12 months at commercial flow rates that would exhaust a 10-inch cartridge in 6–8 weeks.
High-flow capacity at low pressure drop: The larger cross-section and carbon block construction maintain rated dechlorination performance at commercial flow rates without the pressure drop that limits 10-inch cartridges to low residential flow — suitable for whole-house and commercial kitchen applications without flow restriction.
Complete free chlorine removal: Sintered carbon block construction, not granular — water cannot channel through and must contact the full carbon mass, achieving consistent complete dechlorination at all flow rates within the rated capacity of the cartridge.
Simultaneous removal of taste and odour compounds: Activated carbon adsorbs chloramines, THMs, VOCs, and organic compounds causing taste and odour in Oman’s municipally treated supply — improving the quality of all water processed through the housing.
Standard 4.5-inch OD jumbo format: Compatible with all big blue and jumbo filter housings in the 20-inch format — the same housing used for 20-inch PP sediment cartridges, allowing a sediment/carbon two-stage pre-treatment system to be built from a pair of identical housings.

Frequently Asked Questions

How do I know when to replace the jumbo carbon block? The most reliable indicator is chlorine breakthrough — test the filtered water for free chlorine using a simple pool/drinking water test strip. When filtered water shows measurable free chlorine (>0.05 mg/L), the cartridge is exhausted and requires immediate replacement to protect downstream equipment. Schedule replacement every 6 months as a preventive measure at commercial flow rates.
