Summary

This document provides an overview of SUEZ's water and process solutions for the brewing industry, emphasizing sustainability and efficiency. It details various chemical treatment programs, monitoring technologies, and services aimed at addressing challenges in brewing operations, including water usage, energy consumption, and environmental impact.

SUEZ Solutions for the Brewery Industry

SUEZ offers a comprehensive suite of solutions categorized as:

• Process Solutions
• Cooling Water Services
• Boiler Treatment
• Water and Wastewater Treatment
• Membrane Chemicals
• Monitoring Solutions

Tunnel Pasteurizer Treatment

Corrosion and Scale Control: Challenges include corrosion of internal equipment, pipes, heat exchangers, and can/bottle crowns due to oxygenated, potentially corrosive water. Scale formation can affect efficiency and product appearance. Proper water conditioning with corrosion inhibitors and pH control, along with scale inhibitors and dispersants, is essential.

Microbiological Control: Microbiological fouling by bacteria and fungi is a significant challenge, leading to odor, plugged spray nozzles, and reduced efficiency. Nutrients from container leakage or airborne contamination can promote growth. SUEZ provides biocide programs for both operational and holdover periods.

Off-Line Cleaners: Product debris, broken glass, and slime can accumulate, necessitating cleaning. SUEZ offers boil-out programs with solutions typically between 0.5-5% strength to clean surfaces, improve heat transfer, reduce boil-out frequency, and increase throughput.

Process Solutions

Can Staining and Spotting: Due to changes in can coating technology, breweries now face can spotting (dome staining), an aesthetic issue related to aluminum corrosion. Contributing factors include insufficient can coating, high water alkalinity, pH, silica, and chlorine residuals. SUEZ offers Balanced Alkaline Technology (BAT), zinc, corrosion and scale inhibitors, and surfactants to prevent this.

Spent Grain Recovery System: SUEZ provides FDA-approved polymers and deposit control agents to enhance the dewatering of spent grain for animal feed.

Anti-Scuffing: For glass bottle washing, SUEZ's FoodPro* DCF product line acts as a cleaning and anti-scuffing agent, reducing glass mass loss by over 50%.

Bottle and Keg Washers: SUEZ offers solutions including scale inhibitors for rinse zones, surfactant mixes for label removal, and silicone-free defoamers.

Crown and Cork Corrosion: Corrosion on the edges of crown corks and bottle caps can occur where paint coverage is incomplete. SUEZ provides specific products to protect crowns and corks from corrosion during pasteurization and other processes.

Cooling Water Services

Cooling Water in Brewery Plants: SUEZ addresses microbiological proliferation, deposition, scaling, and corrosion in cooling towers and heat exchangers.

• Microbiological Control: Addresses bacterial contamination and biofilm formation that reduces heat transfer and increases microbiologically induced corrosion (MIC).
• Deposit Control: Manages the accumulation of mineral scales and particulate deposits on heat exchange surfaces, which reduces efficiency and can lead to production loss.
• Corrosion Control: Mitigates electrochemical reactions that thin tubes or cause pitting, especially in heat exchangers and piping.

GenGard Technology:* This technology for open recirculating cooling systems controls corrosion and deposition across a neutral to alkaline pH spectrum. It includes:

• Stress Tolerant Polymer (STP) for steel corrosion prevention and iron/solids deposition control.
• Alkaline Enhanced Chemistry (AEC) for calcium carbonate scale inhibition.
• Halogen Resistant Azole (HRA) for copper alloy corrosion protection.
• Phosphate-based steel corrosion inhibitors.

Water and Wastewater Treatment

Wastewater Treatment Benefits: SUEZ's programs improve liquid/solid separation, enhance biological systems for soluble contaminant removal, and increase gas production.

Biological Control: SUEZ offers products to manage microbial growth in various water systems, including wastewater treatment, to prevent disease and ensure equipment operation.

Clarification: Custom polymer formulations remove organic color, hardness, iron, and suspended solids, reducing the need for pH adjustment and decreasing sludge volume.

Metals Removal: SUEZ provides solutions to reduce heavy metals (e.g., lead, copper, chromium, iron, manganese) from waste streams to meet regulatory compliance.

Odor Control: Advanced products and treatments are offered for cost-effective odor management in water processing and wastewater treatment.

Boiler Solutions

SUEZ aims to prevent deposits and corrosion in boiler systems to maintain reliability and efficiency while adhering to FDA standards.

Boiler Deposit Control: Optimized chemical treatments and high-quality feedwater (e.g., OptiSperse* AP, OptiSperse CL, OptiSperse PO Series) maintain boiler cleanliness for efficient heat transfer.

Boiler Corrosion Control: Treatments address oxygen pitting in preboiler circuits and corrosion in condensate systems caused by alkalinity, oxygen ingress, or process contaminants. Oxygen scavengers like CorTrol* IS or CorTrol OS Products are used.

Steam Purity: Maintaining high steam purity is crucial for the safe and efficient operation of rotating equipment and to prevent issues like water hammer.

Membrane Chemicals

MemChem* solutions are designed to reduce operating costs and water/energy demand while improving environmental safety. Products include dechlorination agents, antiscalants, biocontrol agents, cleaners, and filtration aids for various pure water equipment (cartridge filters, MMF, carbon, microfiltration, ultrafiltration, nanofiltration, RO).

On-Site Services: Water chemistry testing, microbiological analysis, system audits, CIP training, and dosage optimization. Off-Site Services: Membrane autopsy, complete water analysis, and membrane restoration.

MemChem Solutions:

• SoliSep MPT Filtration Aid:* Removes fouling particulates, reduces cleaning frequency, and extends filter/membrane life.
• MPH NSF pH Adjustment: Maintains pH, reduces scaling and fouling potential.
• DCL Dechlorination: Removes chlorine to protect membranes.
• Biocontrol and BioMate MBC: Maintain system cleanliness and membrane rejection.
• HyperSperse MDC and MSI Antiscalant:* Optimizes RO operation and extends membrane life.
• Kleen MCT Cleaner: Restores membrane performance and extends life.

Productivity Tools:

• Argo Analyzer Software:* Predicts fouling potential, guides antiscalant selection and dosage, and supports cost savings.
• Winflows Engineering Design:* Simulates RO system configuration and predicts permeate quality.
• RO Normalization Data Sheet: Tracks RO performance and aids troubleshooting.

TrueSense Monitoring and Control

TrueSense is a technology platform for optimizing productivity and water savings in cooling water systems. It integrates:

• Direct Online Monitoring: Measures critical water chemistries (orthophosphate, polymers, halogens).
• Personal Instrumentation: Reduces offline testing time.
• Data Analysis and Display: Provides system insights.

Key Components:

• TrueSense Online for Cooling: Monitors core chemistries for effective cooling water treatment, enabling tighter control, reduced water use, and lower operating costs.
• TrueSense View: A knowledge-management solution for visualization, analysis, alarming, and reporting, with flexible local or web-based data storage and wireless features.

TrueSense is designed to work synergistically with SUEZ's GenGard cooling water chemistry.

Case Studies

Several case studies illustrate the benefits of SUEZ's solutions in breweries, including:

• Improved performance and water savings in pasteurizer treatment by optimizing chemical dosing and control strategies.
• Significant cost savings through a biocide regime, zinc inhibitor, and pH control in pasteurizer treatment, reducing microbial activity and corrosion.
• Reduction in beer out temperature and quarantined products through improved cooling tower fouling control and biocide programs.
• Increased chiller capacity and energy savings by using Ferroquest rust remover to clean chilled water systems.
• Successful tunnel pasteurizer treatment with Bioscan for microbiological control, leading to a high return on investment.
• Elimination of corrosion during tunnel pasteurization, saving significant costs by implementing an effective biocide dosing system and neutral corrosion inhibitor.
