Dewatering is the process of extracting liquid from a sludge slurry. Different dewatering techniques are used to carry out the process. These techniques may be used in refineries, wastewater treatment plants, drinking water facilities, and power plants. In this blog post, we will discuss three common methods of dewatering water treatment.

Belt Filter Press

The process of belt filter press is more commonly used when it is acceptable for filter cakes to have high-moisture content. Generally, this process produces about 18% to 25% solids by mass. It is extremely effective when it comes to high-volume wastewater streams – because it is conditional – where a huge production of the average-quality filter cake is acceptable. The belt filter press method is typically used in public wastewater treatment plants. There are different types of sludge dewatering equipment used for the belt filter press. 

The belt filter press system is mostly used for the following:

• Public wastewater treatment sludges
• Paper mill sludge
• River silt

Centrifuge

The centrifuge method is used to separate components that have different densities by employing a high rotational speed. The idea of this process is based on buoyancy – an upward force. A component with less density would be suspended above the mixture; whereas, a high-density component would fall to the bottom. This process generally produces about 25% and 35% of solids by mass. 

The primary benefit of the centrifuge method is its speed. Therefore, the process is typically reserved where the main priority is to recover oil, and residual solids’ quality is not much of an issue. Take a look at some of the sludge dewatering rental equipment to better understand the components involved. 

Plate and Frame Filter Press

The plate and frame filter press method use recessed-chamber filter plates that help to extract liquid from solid. In this process, two separate plates are put together in the shape of a chamber. This builds pressure on the slurry and squeezes out the filtrate through the lining cloth that acts as a filter in the chamber. The filter plate cloth collects the filter cake on its surface and drops it down into a horizontal conveyor. 

This process is highly effective and produces filter cake that is about 40% to 70% solids by mass. Plus, it provides cost-efficient disposal and transportation since it produces the greatest solid material content, which makes it even more beneficial. 

One of the advantages of using the plate and filter press process is that it does not require any specific licensing in order to operate the machine. In addition, the products are easy to transport as they are cake-like, stackable solids. Click here to learn more about our dewatering services.

No matter your industry, it’s always important to keep your equipment in good working order. That’s certainly true in wastewater treatment, or in any field that relies on digesters. After all, digester tanks play an essential role in the water treatment process, making it possible to efficiently separate liquids and solids. Digesters should always run at something pretty close to maximum capacity, but over time, that capacity may be limited by the buildup of gunk and crustacea.

One way to handle this problem is to hire digester cleaning services… but as you might imagine, not all digester cleaning services are created equal. As such, it’s important to do your due diligence and ensure you hire the right company to help with your anaerobic digestion plant. And that begins by knowing some of the most common (and potentially costly) mistakes.

The 5 Most Common Mistakes When Hiring a Digester Cleaning Service

For example…

1) Assuming that all equipment is created equal.

One of the first things to recognize is that there isn’t a lot of standardization with regard to digester cleaning systems. Different companies will offer different kinds of equipment to help with your anaerobic digester mixing systems, so it’s always worthwhile to ask your vendor for more information about their tech portfolio. Ensure that they are working with cutting-edge equipment, and that they have a range of systems sufficient for providing you with a customized solution.

2) Not getting the right personnel.

Do you have team members who know their way around anaerobic digester mixing systems, and specifically who know all about the cleaning process? If not, you may need to train them, which can be time-consuming. Alternatively, you can look for a digester cleaning service that will send already-trained personnel to handle things on your behalf. Often, this is the most effective and efficient way forward.

3) Not asking about down times.

While your anaerobic digestion plant is getting cleaned out, it will usually mean a break from your usual production. But how long will that break last? And how much efficiency are you going to lose? Always ask in advance so that you can plan accordingly.

4) Not asking about emergency options.

Sometimes, as in the case of flood and disaster cleanup, you may need to get your digester cleaned in a real rush. Some services will actually offer rapid response options, specifically with flood and disaster cleanup in mind. Don’t hesitate to ask about emergency response options if you need them.

5) Assuming that digester cleaning companies are all alike.

Just to reiterate what we said above, it’s crucial to remember that the digester cleaning profession is varied, and not all companies are the same. It pays to shop around and compare options, because you’ll find that digester cleaning providers differ quite a bit in terms of experience, professionalism, tech sophistication, price point, turnaround time, customer service, and beyond.

Case in point: Access to an anaerobic digester can significantly expedite the flood and disaster cleanup process. And the right digester cleaning services can ensure that this equipment is working at peak functionality.

Consider the advantages that digester cleaning contractors can bring to any flood and disaster recovery project.

What is a Digester?

Let’s start at the beginning: When we talk about anaerobic digester mixing systems, what exactly are we talking about?

Anaerobic digestion is a process in which micro-organisms break down organic matter (such as solid waste, or manure), without the need for oxygen. A digester is simply the structure in which the anaerobic digestion process can take place.

A digester can be crucial in the aftermath of a flood, especially if disruption to normal sewage services has led to a significant surplus of organic waste. To eliminate this waste speedily and cost-effectively, it may first be helpful to break it down as much as possible. That’s where anaerobic digester mixing systems come into play.

The Importance of Digester Cleaning Services

So what about the role of digester cleaning contractors?

To understand the importance of digester cleaning, it’s first important to know this: Simply due to their regular operation, digesters tend to accumulate layers of grit, sludge, and even crustacea. Essentially, these large tanks become covered in gunk.

This layer of gunk has a couple of effects. One, it means that the tanks have less capacity to hold waste. And because of this, it also means that the anaerobic digestion process can’t proceed quite as efficiently as it would normally.

Following a natural disaster, of course, you’ll want your equipment to be in something pretty close to optimal condition, ensuring that you can clean up as quickly and as efficiently as possible. As such, it’s generally best to stay up to date with digester cleaning needs. This helps keep mission-critical equipment in good working order, ready for use in truly dire situations.

And of course, one of the best ways to keep your digester equipment well-maintained is to hire a digester cleaning specialist, like P&H Senesac.

Sludge dewatering refers to the practice of reducing waste by volume, preparing it for more efficient and cost-effective disposal. This has long been one of the core processes in water treatment. Generally, it’s something that requires advanced technology.

Specifically, water treatment companies use sludge dewatering rental equipment, from vendors like P&H Senesac, to get the job done.

If you have never rented dewatering water treatment equipment, you may have some questions about the process. In this post, we’ll offer a little bit of background for the dewatering pump rental experience.

What’s Sludge?

First, it may be helpful to clarify some terminology. As we talk about sludge dewatering rental equipment, it’s important to define sludge.

Basically, sludge is a semi-solid slurry, produced in many industrial and municipal applications. The purpose of the dewatering process is to separate the liquid and solid components of this slurry, leaving you with solid cakes that weigh a lot less and thus are easier and cheaper to get rid of.

Given that waste removal is often governed by strict sustainability protocols, effective sludge removal may be necessary for achieving compliance, to say nothing of minimizing expenses.

What are the Benefits of Sludge Dewatering?

With all of that said, let’s dig a little deeper into some of the benefits of sludge dewatering.

• Decrease the volume of waste. By removing all the water from waste, you’re left with solid cakes that are both smaller and lighter.
• Reduce the cost of transportation. Because you’re making your waste so much smaller and lighter, you can transport it to a disposal site much more cost-effectively.
• Lower the risk of leaking. When you’re only transporting these dry cakes, you can almost completely eliminate the risk of spillage or leaking.
• Recycle wastewater. A huge benefit of sludge dewatering water treatment is that, by removing contaminants from liquid waste, you can then recycle it.
• Minimize environmental impact. Finally, because you’re making your waste more compact, you’re minimizing the ecological impact of your waste disposal.

These are just a few of the reasons to prioritize sludge dewatering… so now, let’s get into dewatering rental equipment.

The Basics of Dewatering Pump Rental Equipment

There are different kinds of equipment that can be used in the sludge dewatering process. One of the most common types of equipment, historically, has been the press, which essentially squeezes all the moisture out of slurried waste.

A more advanced and effective option is the centrifuge, which essentially spins the slurry until the solid and liquid wastes are separated. This is the type of equipment we focus on here at P&H Senesac.

In addition to choosing the right kind of equipment, there are a few other considerations to make regarding your dewatering equipment. For example:

• Do you need your sludge dewatering equipment ASAP? Some companies, including P&H Senesac, will offer equipment rentals on an emergency basis.
• Also ask yourself whether you need skilled technicians to operate the equipment, or whether you already have that capability in-house.
• As you talk with different equipment vendors, make sure you inquire about the production down times you can anticipate.

These are just a few things to think about as you look into different pump rentals.

How to Hire the Right Dewatering Pump Rental Services

Ask About Rapid Deployment

Hopefully, you’ll have plenty of advance warning that you need to hire a sludge dewatering rental equipment company. In some situations, however, you may not have the luxury of time. In real emergencies, it’s essential to ask about rapid response deployment, ensuring your vendor can have equipment on the ground and ready to go within 24 hours or so. Not all companies can deploy so quickly, so this is definitely something worth asking about directly.

Browse the Tech

Frankly, when it comes to dewatering water treatment technology, there’s a lot of variation in overall quality and effectiveness. Before selecting a vendor, have them walk you through some of the tech options they offer. Look for a company that has some fairly state-of-the-art pumps, and also a company that can offer you a variety of options to choose from. After all, when it comes to selecting the right dewatering pump, there are no one-size-fits-all solutions.

Inquire About Personnel

Getting the right dewatering equipment is obviously important, but so is being able to use it effectively! Your team may or may not have the right level of expertise, and even if you do, working an unfamiliar dewatering pump may prove more time-intensive than you’d like. Some of the best dewatering pump rental companies will send highly trained personnel to help use the pump effectively, allowing you and your team to focus on other core efficiencies.

Verify the Expected Downtime

Usually, when you get into dewatering water treatment processes, it involves an interruption from your regular operations. This downtime is par for the course, but naturally, you want to keep lost productivity to a minimum. Before hiring a dewatering pump rental company, be sure you ask them what sort of interruptions you can anticipate. A good dewatering pump rental company should be able to give you a rough time frame.

Do Your Due Diligence

More generally, just bear in mind that pump rental companies are all different, and it’s worth checking into two or three different companies to compare and contrast the options, the pricing, etc. In particular, ask about experience level, years in the business, and the technology portfolio. Also, don’t hesitate to request references or testimonials from past customers and clients. A good, reputable company should be willing to offer you some of this info.
