Wastewater is a fairly generic term, simply denoting water that contains any kind of solid or liquid contaminant. For example, municipal wastewater contains organic sludge (e.g., human waste), while industrial wastewater might contain inorganic sludge (e.g., industrial chemicals that have been disposed of).

Wastewater usually accumulates in large volumes, which often means a high concentration of solid waste. To dispose of this waste quickly and effectively, allowing for the proper treatment of the water itself, it’s critical to separate the solid and liquid elements of wastewater.

There are a number of technologies that can be used to achieve this goal, but one of the most dependable is the wastewater centrifuge. 

Wastewater Centrifuges at a Glance

So, what is a wastewater centrifuge, exactly?

A wastewater centrifuge is a type of separation machine. Using several thousand Gs of centrifugal force, it separates the sludge from the rest of the wastewater. The sludge accumulates along the periphery of the centrifugal tank or bowl, where it may then be discharged. The remaining, solid-free liquid may then pass through a liquid outlet, typically located at the other end of the tank or bowl.

What are the Different Types of Wastewater Centrifuge?

There are three basic types of centrifuges that can be applicable in wastewater treatment.

Sludge Thickening/Dewatering Type

This type of centrifuge removes water from slurries, thereby thickening the sludge. To put it differently, this type of centrifuge dewaters and concentrates (or thickens) sludge. This can be helpful for continuously processing large quantities of sludge-ridden water. Most often, this type of centrifuge is used to deal with oilfield drilling mud, livestock manure, and municipal sewage.

Clarifying Type

The wastewater clarifier is a disc-stack type, producing high speeds and high centrifugal forces to separate suspended particles at the micron level. These particles are pushed to the edges of the bowl and automatically purged. This type of centrifuge application is most commonly employed in mining applications.

Oily Wastewater Separator

Often, industrial wastewater is accompanied by oil, as well as sludge. This presents a unique challenge, as the oil cannot be disposed of through normal drains. This type of centrifuge is specifically designed to provide a liquid-liquid-solid separation effect.

The Benefits of Wastewater Centrifuges

There are a number of benefits to the centrifugal method of treating wastewater. These benefits include:

• Reduced transportation and disposal costs.
• Greater durability for the wastewater treatment equipment.
• A relatively low operating expense.
• Minimal operator requirements.
• Compact size.

Breweries tend to produce large quantities of wastewater, the natural byproduct of the brewing process. Surprisingly, this wastewater can be very harmful to the environment, as it’s usually dense in sugar, alcohol, and other residuals that cannot simply be released untreated. For this reason, breweries must place rigorous wastewater treatment processes in place.

 

This can be easier said than done. Brewery wastewater treatment usually involves an aeration process, which requires advanced technology, lots of power, and high electricity costs. Nevertheless, it’s crucial for breweries to find a way to treat their effluents effectively, avoiding any regulatory non-compliance.

 

So, what should breweries know about managing their wastewater treatment process? Here are a few guidelines to keep in mind.

 

Tips for Brewery Wastewater Treatment

• Breweries must meet discharge limits. If you send your wastewater into the local sewer system, then you need to make sure you comply with local limits and prohibitions. The specifics can vary by municipality.

• It’s crucial to manage total suspended solids (TSS). Spent yeast, hops, and barley can potentially clog the sewage system. Breweries that release them into the local sewer may be subject to fines or other regulatory penalties. Be sure your wastewater treatment process involves the filtration of solids.

• Acidity is also an issue. Brewery wastewater often has a high level of acidity, which can corrode storage containers and also damage sewer systems. It’s important to check local limits on wastewater pH level, properly aerating wastewater to keep that acidity level in check.

• Temperature matters, too. Discharging wastewater at a high temperature can also present some complications, resulting in regulatory concerns. Again, it’s important to check the local municipality’s guidelines and restrictions.

• Seek a discharge permit, as needed. Depending on the size of your brewery and the amount of wastewater you discharge, you may need to apply for a local permit. The local sewage and wastewater management system can provide further information.

• You may also need to install an access point. Some municipalities will require you to have an easy-access monitoring point, allowing representatives of the city or county to come take samples or test your wastewater at their convenience.

Within the automotive industry, water is used in countless ways. For example, automotive plants use water to:

 

• Wash products, equipment, and parts.
• Cool down air conditioning units and boilers.
• Run spray paint booths.
• Provide new vehicles with surface treatments.

 

These are just a few examples among many. Because the automotive sector uses so much water, and for such a wide range of applications, it goes without saying that auto plants produce a large amount of wastewater. And while this is a natural result of industrial activity, it presents automotive companies with some unique challenges.

 

Handling Wastewater in the Automotive Sector

 

The big problem with automotive wastewater, of course, is that it’s usually quite dirty. Automotive wastewater may be heavily contaminated with grease, oil, fats, coolant, radiator fluids, and various suspended solids.

 

Many of these substances are flammable, and pretty much all of them can be toxic to humans and to the natural environment. As such, it would be dangerous for automotive companies to simply release this water into the ecosystem. Not only that, but it would be illegal: Environmental regulations prevent manufacturing companies from disposing of their wastewater without first treating it. To release untreated wastewater would result in massive penalties, to say nothing of a tarnished public image.

 

The Benefits of Wastewater Treatment

 

As such, there are a number of benefits to wastewater treatment in the automotive sector… and some of them are pretty obvious. For instance, automotive companies should treat their wastewater to avoid legal consequences, if for no other reason.

 

But there can be other good reasons to treat wastewater, too. For example, treating water may mean that automotive manufacturers can recycle it. Given the sheer amount of water required to make cars, this can be an incredible way for automotive companies to operate in a more cost-effective way.

 

What are the Options for Automotive Wastewater Treatment?

 

There are a number of options available for automotive manufacturers seeking effective wastewater treatment.

 

• Chemical treatments can be fast-acting and effective, though they can also be expensive.
• Biological processes can also be used to purify water, often through oxygen deprivation.
• Centrifuge technology can be employed to separate solids from liquids, resulting in lightweight, high-density cakes that can be affordably hauled off and recycled.

 

To explore the different options for wastewater treatment, automotive companies are encouraged to reach out to technology providers like PHS.

Naturally, every hotel management team desires to create an optimal guest experience, ensuring the kinds of comfort and convenience that allow them to maintain a competitive edge.

 

There are many obvious aspects to creating a great hotel experience, from spacious rooms to robust room service options, but one aspect that may be less obvious is wastewater treatment. Simply put, hotels need to have a functional and effective wastewater treatment system to ensure the comfort of their guests as well as to maintain compliance with local environmental statutes.

 

Key Considerations for Hotel Wastewater Treatment

 

As hotel managers think about their options for wastewater management, a few factors should be top-of-mind.

 

The Purity of Natural Water Sources

 

If a wastewater treatment system somehow leads to pollution or contamination of local, natural water systems, that could be both an ecological disaster and a PR nightmare for the hotel. Thankfully, if a septic system is properly installed and well-maintained, there is little risk of a contamination issue, even if the system is giving some trouble. Still, repairing a septic system can be costly, and will need to be done quickly to ensure continued quality-of-life at the hotel. For this reason, it’s usually smarter to invest in a more state-of-the-art wastewater treatment system.

 

Different Types of System

 

That raises a question: What types of wastewater treatment system can a hotel management team choose from? There are a number of options, and also several determinative factors:

 

• How many rooms/wastewater-generating units are at the hotel?
• What’s the daily wastewater volume?
• What are the peak volumes both on-season and off?

 

Based on these factors, hotels may find that chemical-based or UV-based systems serve them well, offering long-term and cost-effective wastewater treatment solutions.

 

Installation

 

When it comes to installation of a new system, there are a few things to consider.

 

• Make sure the quality of the effluent is going to meet local environmental standards.
• Check to see if your municipality requires you to have a permit to discharge hotel wastewater.
• Talk with your installation team about the most effective location for placing your new system. Beyond size/capacity, location is one of the most important factors for determining the efficiency of a wastewater treatment system.
• Remember that grease and oil from your hotel kitchen can clog your wastewater system causing it to break down prematurely. A grease trap is essential for avoiding this costly and cumbersome issue.

When you hear the phrase industrial wastewater, what comes to mind? Perhaps you think of the contaminated water that’s produced as a byproduct of the oil and gas industry, mining, or even chemical manufacturing.

 

Actually, industrial wastewater is produced by virtually every manufacturing company, power plant, and industrial environment. In other words, industrial wastewater is generated by the companies that make your clothing, your car battery, your mobile phone, and your household appliances.

 

What this means is that, within any industry, there is a need for a wastewater management process. Simply put, contaminated water cannot be released back into the environment, or even reused in plant operations, without first being properly treated. Without a process in place to remove metals, organic contaminants, and inorganic contaminants from wastewater, industrial organizations may run afoul of any number of environmental regulations.

 

Which Industries Produce Wastewater?

 

Just to provide a sense of how widespread wastewater generation is, consider a few examples of industries that produce wastewater at high volumes.

 

Metal Finishing

 

Metal finishing operations usually generate a slurry of metals dissolved in liquids. If released into the environment untreated, these slurries can pose health risks to animals and humans alike.

 

Commercial Textiles

 

The commercial textiles industry processes billions of pounds of laundry each year, which naturally produces large amounts of water contaminated by grease, oil, and other pollutants. This water must be treated before it is released.

 

Mining

 

Mining operations usually yield high quantities of water mixed with finely-ground rock. Disposing of this wastewater can be costly and inefficient, but proper treatment can make disposal a little bit easier.

 

Power Plants

 

Fossil-fuel power plants, particularly those that are coal-fired, rank among the most prolific producers of industrial wastewater. The wastewater generated by power plants often has high concentrations of lead, mercury, arsenic, and other hazardous toxins, making effective treatment a must.

 

Food Processing

 

Even food processing facilities tend to yield high quantities of wastewater. And this wastewater is often contaminated with the pesticides and herbicides used to develop foods at an industrial scale. Naturally, proper treatment is an essential responsibility of these food processing companies.

 

Properly Handling Industrial Wastewater

 

No matter the industry, there is an acute need for effective wastewater management processes. Thankfully, best-in-class technologies such as filter presses and centrifuges can have a major impact, effectively separating solid waste from wastewater and thereby facilitating a more cost-effective disposal process. This also helps industrial organizations maintain full compliance with environmental regulations.
