Line Supply Purpose

Process water distribution lines accumulate organic compounds from biofilm growth, piping materials, or upstream contamination. Carbon filtration in return or recirculation loops maintains water quality removing dissolved organics before reuse or critical process contact.

Filter Configuration

Vertical pressure vessel with supply water inlet, activated carbon bed 30-48 inches depth, support gravel layers, underdrain collection system, polished water outlet to process users. Empty bed contact time 8-15 minutes for effective adsorption.

Carbon Media

Granular activated carbon from coal or coconut shell. Particle size 8x30 or 12x40 mesh. High iodine number for organic adsorption capacity. Carbon life 1-3 years depending on organic loading and water quality.

Operating Pressure

Typical 60-125 psig matching process water distribution pressure. Clean bed pressure drop 8-12 psi. As carbon loads with organics, pressure increases modestly. Breakthrough monitoring indicates replacement requirement.

Organic Removal

Adsorbs dissolved organics, humic substances, taste and odor compounds, trace industrial chemicals, and biofilm precursors. Improves water stability preventing biological regrowth in distribution. Reduces total organic carbon maintaining process water quality.

Material Selection

Stainless steel 304/316 for food, pharmaceutical, and high-purity applications. Carbon steel with epoxy lining for industrial process water. Internal components prevent contamination pickup. Materials meet sanitary or process requirements.

Chlorine Reduction

Removes residual chlorine or chloramines from municipal supply protecting sensitive processes and products. Dechlorination to under 0.05 ppm. Critical for food, beverage, and pharmaceutical manufacturing.

Backwash Requirements

Periodic backwash removes particulates redistributing carbon bed. Flow rate 8-10 gpm per square foot. Backwash extends carbon life preventing premature pressure buildup. Frequency depends on supply water quality.

Applications

Food and beverage process water, pharmaceutical purified water distribution, electronics manufacturing ultrapure water, laboratory water systems, and any process requiring organic-free water supply.

Breakthrough Monitoring

TOC analyzers or chlorine measurements detect carbon exhaustion. Continuous monitoring prevents poor quality water reaching processes. Alarm triggers carbon replacement before breakthrough impacts operations.

System Integration

Positioned in process water recirculation loop or supply line before critical use points. Maintains consistent water quality despite variations in municipal supply or distribution system conditions.

Capacity Sizing

Volume based on water flow rate and required contact time. Balance between carbon inventory and replacement frequency. Typical design provides 12-24 months operation before exhaustion.

Temperature Considerations

Process water temperatures typically ambient to 40C. Carbon capacity reduces at elevated temperatures. Design accounts for maximum operating temperature in capacity calculations.

Performance Benefits

Maintains consistent process water quality. Removes taste and odor improving product quality. Protects processes from organic contamination. Simple proven carbon adsorption technology.

Construction Standards

Pressure vessels per ASME Section VIII. Sanitary design per 3-A standards for food/pharma applications. Materials verified for water contact. Complete documentation with contact time calculations and performance specifications.
