How Manufacturers Use Water

Manufacturing is thirsty work. From cooling to cleaning, water plays a crucial role in industrial processes. But this massive water use comes with challenges.

Here's how manufacturers rely on H2O:

1. Cooling and Heating

Water regulates temperatures in manufacturing. Cooling towers are major users, removing heat from industrial processes.

Ford's Cologne plant cut cooling tower water use by 40% by improving filtration and recycling wastewater.

2. Cleaning and Rinsing

Water washes away contaminants in manufacturing, from car parts to food processing equipment.

3. Product Ingredients

Some products contain water directly, like beverages, paints, and cleaning products.

Coca-Cola aims to replenish 100% of the water used in their finished beverages back to communities and nature.

4. Processing Raw Materials

Water helps transform raw materials into finished goods in pulp and paper production, metal processing, and chemical manufacturing.

5. Steam Generation

Boilers use water to create steam, powering turbines and providing heat.

Manufacturing accounts for about 25% of global freshwater withdrawals. But it's not just quantity - quality matters too. Some industries need ultra-pure water:

• Microchip makers
• Pharmaceutical companies
• Food and beverage producers

These companies often treat city water on-site to meet their standards.

Water isn't cheap. U.S. industrial water rates can range from $10,053 to $82,537 per month for 10 million gallons.

As water becomes scarcer, manufacturers face:

• Higher costs
• Tougher regulations
• Supply risks

But smart companies are adapting. They're recycling, reusing, and rethinking their processes. Nike, for example, has implemented water recycling in their factories.

The takeaway? Water is vital for manufacturing. Using it wisely isn't just good for the planet - it's good for business.

10 Ways to Save Water in Manufacturing

Manufacturing guzzles water. But smart factories are cutting back. Here's how to slash water use in your plant:

1. Check and Track Water Use

You can't cut what you can't count. Start here:

• Put meters on key equipment
• Use software to monitor usage
• Set reduction goals

2. Boost Cooling Tower Efficiency

Cooling towers are often the biggest water hogs. To trim waste:

• Up the cycles of concentration
• Add drift eliminators
• Clean and maintain regularly

3. Go Closed-Loop

Closed-loop systems recycle water instead of dumping it. They can cut water use by up to 95%.

4. Upgrade to Water-Smart Equipment

New tech can slash water use. For example:

• Dry machining ditches cutting fluid
• Waterless urinals save thousands of gallons yearly
• High-pressure, low-volume nozzles use less water for cleaning

5. Treat and Reuse Wastewater

Don't flush good water. Clean it and use it again.

6. Harvest Rainwater

Free water falls from the sky. Catch it for:

• Cooling
• Cleaning
• Watering plants

7. Clean Smarter

Cleaning eats up water. Try these tricks:

• Start with dry methods (sweep, vacuum)
• Install Clean-in-Place systems
• Use high-pressure, low-volume sprayers

8. Hunt Down Leaks

A tiny drip wastes tons. To stop leaks:

• Inspect regularly
• Use leak detection tech
• Fix issues fast

9. Train Your Team

Your staff is key. Make sure they:

• Get why water matters
• Know how to use equipment efficiently
• Report waste and leaks

10. Design Water-Wise Products

Think water from the start:

• Pick materials needing less water to process
• Design for efficient manufacturing
• Consider total lifecycle water use

These steps pay off. Ford cut cooling tower water use 40% at their Cologne plant by improving filtration and recycling wastewater.

Bottom line: Saving water helps the planet AND your profits.

Tracking Water Savings

Want to make your water conservation efforts count? You need to track your savings. Here's how:

Set up water meters

Install meters on key equipment and processes. This gives you real-time data on water use.

Use tracking software

Try systems like Energyly's Water Monitoring System. It tracks data 24/7 and alerts you to leaks or unusual usage.

"Intelligent water leakage detection and automatic alerts are sent out immediately." - Energyly Water Monitoring System

Calculate potential savings

Use this formula to estimate savings from upgrades:

Monitor key metrics

Keep an eye on:

• Total water use (m3/year)
• Water use per employee (L/person/day)
• Water use change (% vs. previous year)

Check for leaks

Small leaks add up fast. A faucet dripping twice per second? That's 6,000 gallons wasted yearly.

Use water footprinting

This method measures your total water impact, similar to carbon footprinting.

Try free tools

The AWE Water Conservation Tracking Tool helps evaluate savings and costs of conservation programs.

By tracking closely, you'll spot waste and prove the value of your efforts. Take Ford, for example. They cut cooling tower water use by 40% at their Cologne plant just by improving filtration and recycling.

Bottom line? You can't improve what you don't measure. Start tracking today to see real water savings tomorrow.

Overcoming Water-Saving Hurdles

Manufacturers often hit roadblocks when trying to save water. Let's break down common problems and their solutions:

High costs

Companies balk at pricey water-saving tech. Here's how to get past that:

• Think long-term. Ford slashed water use 62% globally from 2000 to 2012, saving 10.6 billion gallons.
• Bundle big upgrades with quick wins. Use savings from easy fixes to fund bigger projects.
• Factor in energy savings. Less water often means lower energy bills.

Change resistance

Staff might push back on new methods. To tackle this:

• Start small. Test new tech in one area, get feedback, then scale up.
• Educate employees on why water matters.
• Show how changes benefit both the company and the planet.

Data drought

Can't spot waste without good data. Try these fixes:

• Add water meters to key equipment.
• Use tracking software like Energyly's Water Monitoring System.
• Set up water footprinting to measure total impact.

Tech challenges

Some processes are water hogs. To cut back:

• Try dry machining where you can.
• Use membrane biological reactors to treat and reuse wastewater.
• Upgrade equipment. Kimball Office saved 13 million gallons from 2008-2012 by tweaking their coating process.

Red tape

Rules can make water reuse tricky. Here's how to navigate:

• Team up with local officials on clear guidelines.
• Join efforts like the National Blue Ribbon Commission for Onsite Non-potable Water Systems.
• Push for policies that back water reuse in manufacturing.

The Future of Water Saving in Manufacturing

Water scarcity is pushing manufacturers to get smart about conservation. Here's how they're doing it:

AI and Machine Learning

AI is changing the game for water management. It's helping companies:

• Predict water needs
• Spot leaks instantly
• Make distribution super efficient

Ecolab's using AI to crunch water data. The result? Kevin Doyle, their Chief Digital Officer, says:

"We've seen increases already in the early stages of that program in the hundreds of millions of dollars of value creation and value potential."

Smart Water Systems

The smart water market's booming. It's set to nearly double from $16.08 billion in 2023 to $30.80 billion by 2028. Why? These systems tackle big water issues:

Digital Twins

Digital twins are virtual copies of water systems. They let companies:

• Test ideas risk-free
• Find and fix inefficiencies
• Predict maintenance needs

ABB's jumping on this trend. In 2022, they launched a smart wastewater solution using digital twins.

New Treatment Tech

Manufacturers are getting creative with water treatment:

• Reverse osmosis for reuse
• Nanotech for cheaper, safer filtration
• Biomimicry for desalination

These methods save water AND energy. Membrane tech, for example, has slashed desalination costs from $1 to $0.50-$0.80 per cubic meter in just five years.

Data and IoT

The Internet of Things (IoT) is set to revolutionize water management:

• Smart sensors track usage and quality in real-time
• IoT platforms manage a web of connected devices
• Advanced meters provide precise consumption data

This data goldmine helps manufacturers spot and fix water waste fast.

As water gets scarcer, these technologies will be crucial. Companies that invest now will be ready for future challenges and regulations.

Wrap-Up

Water conservation in manufacturing isn't just good for the planet—it's smart business. Here's what you need to know:

1. Start small, think big

Even tiny changes can lead to big water savings. Ford cut water use by 50% in some processes just by switching to dry-in-place chemical agents.

2. Use tech

AI-powered leak detection and smart water systems are game-changers. They help spot waste and boost efficiency.

3. Reuse and recycle
