CBI Water Hub

Uses coagulants (alum, PAC, ferric chloride) + polymers to aggregate colloids. Critical pre-treatment step that dramatically improves sedimentation and filtration performance. Modern systems achieve >99% solids removal in high-turbidity applications. Directly mitigates climate-driven cyanotoxin and PFAS mobilization that degrade water quality per ASHRAE 188/514 and WRAF frameworks.

Gravity settling + multimedia, cartridge or UF membranes. Removes 95–99% of suspended solids and turbidity to <0.5 NTU in modern systems. Essential for downstream disinfection efficacy and PFAS pre-treatment. Reduces water quality degradation from sediment-bound contaminants under flood/drought conditions (WRAF risk scoring).

Real-time dosing of corrosion inhibitors, biocides, antiscalants, oxygen scavengers and pH buffers. Prevents scaling, corrosion and biofouling in closed and open systems. Integrated PLC control ensures precise dosing and cooling-tower drift minimization, preserving water quality under climate stress (ASHRAE 514).

High-recovery RO + EDI for ultrapure water production. Achieves 99.9% ion removal including short- and long-chain PFAS. Energy-efficient designs reduce operational costs by up to 40% and enable wastewater reuse. Critical for reversing climate-amplified PFAS contamination that severely impacts water quality (ASHRAE 188 integration).

Chemical-free pathogen control. UV + ozone combination destroys bacteria, viruses, and protozoa while breaking down organic micropollutants and cyanotoxins. Ideal for Legionella control and emergency radiological protocols in premise plumbing. Mitigates climate-driven water quality decline per WRAF metrics.

MBR combines biological treatment with membrane separation. Produces high-quality effluent suitable for reuse. Anaerobic systems recover biogas from high-strength wastewater. Supports ZLD and climate-resilient reuse targets while countering PFAS and cyanotoxin impacts on water quality (ASHRAE/WRAF).

Generates powerful hydroxyl radicals (O₃/UV, H₂O₂/UV, Fenton) to destroy persistent organics, pharmaceuticals, and PFAS compounds (including volatile air-water emissions). Proven >99% removal of emerging contaminants. Directly restores water quality degraded by climate extremes and PFAS persistence (ASHRAE 514).

Operates above 374°C and 22 MPa in supercritical water state. Achieves >99% PFAS destruction for AFFF, industrial wastewater, and landfill leachate. Emerging gold standard for complete mineralization without incineration byproducts. Critical for long-term water quality recovery under climate risk frameworks.

Uses electrical currents to generate oxidants that break PFAS at molecular level. Scalable for concentrated streams. Plasma and foam fractionation provide complementary separation/destruction pathways. Addresses PFAS-driven water quality impairment under changing climate conditions (WRAF).

Combines RO, evaporation, crystallization to eliminate liquid discharge. Recovers >95% water. Includes advanced drift eliminators to minimize aerosol emissions of PFAS and pathogens. Prevents secondary water quality contamination from climate-stressed cooling systems (ASHRAE 188).

ASHRAE 188 provides systematic Water Management Program (WMP) development for Legionella and other hazards. ASHRAE 514 extends to broader climate resilience. The Water Resilience Assessment Framework (WRAF) integrates sea-level rise, drought, flood, extreme precipitation into quantitative risk scoring. Automatic activation of isolation, enhanced treatment, and public notification for cyanotoxin/radiological events linked to climate extremes. PFAS air-water cross-media monitoring embedded in all WMPs. Enhanced water quality impact metrics quantify degradation pathways for proactive mitigation across all sectors.

Controls corrosion vs. scaling tendency. Optimal 7.2–7.8 maintains protective oxide layers while preventing calcium carbonate precipitation. Climate-induced temperature swings and drought accelerate pH shifts, increasing PFAS mobilization and directly degrading water quality through enhanced corrosion and scaling (ASHRAE 188/514 & WRAF scoring).

Influences scaling potential, oxygen solubility, microbial growth rate and chemical reaction kinetics. Temperature excursions often indicate fouling or flow issues. Legionella proliferation peaks between 95°F–108°F. Cyanotoxin blooms and PFAS volatility surge under climate warming, causing severe oxygen depletion and water quality impairment (WRAF climate risk metrics).

Direct proxy for total dissolved solids. Difference between inlet and treated EC measures treatment performance and early indicator of membrane or resin exhaustion. Climate-driven salinity intrusion and drought elevate EC, accelerating PFAS transport and overall water quality degradation (ASHRAE 514 integration).

Highly aggressive pitting corrosion agent, especially to stainless steel. Strict control required in cooling and process systems. Elevated levels from sea-level rise dramatically increase risk of stress corrosion cracking and PFAS co-mobilization, leading to rapid water quality decline (WRAF).

Primary corrosion product indicator. Elevated levels signal active metal degradation and potential deposition problems. Climate stress and PFAS interactions amplify iron release, visibly degrading water quality and system integrity (ASHRAE 188).

Measures water's oxidation state. Critical for effective disinfection and control of anaerobic conditions that produce H₂S and MIC. Low REDOX during climate extremes promotes cyanotoxin production and PFAS persistence, directly impairing water quality (WRAF metrics).

Buffering capacity that resists pH swings. Essential for stable chemistry in systems using acid or CO₂-based treatments. Climate extremes reduce buffering, amplifying PFAS toxicity and accelerating water quality degradation (ASHRAE 514).

Maintains protective film on metal surfaces. Concentration must stay within narrow control band for optimal protection without waste. Under-dosing in climate-stressed systems leads to rapid water quality decline and increased PFAS release (WRAF risk scoring).

Indicator of suspended solids, biological activity or filter breakthrough. Climate extremes increase sediment and cyanotoxin loading, elevating turbidity and mobilizing PFAS from sediments, causing widespread water quality impairment (ASHRAE 188).

Persistent emerging contaminants with significant air-water cross-media transport under climate extremes. Climate change increases volatility, mobilization from soils/sediments, and air-water cross-media transport, causing widespread water quality degradation through bioaccumulation and toxicity. Primary remediation techniques include GAC/IX adsorption (separation), RO/NF membranes, and destruction via AOPs, SCWO, electrochemical oxidation. Integrated into all WMPs and remediation plans per jurisdiction-specific regulations and ASHRAE/WRAF frameworks.

Climate-linked (drought/flood/extreme precipitation) mobilization risks. Immediate emergency protocols include enhanced monitoring, advanced oxidation, system isolation, and regulatory/public notification. PFAS co-contamination amplifies toxicity and requires integrated risk frameworks (ASHRAE 188/514, WRAF). Both directly degrade water quality through acute toxicity and long-term ecosystem damage.
