What Sludge Dewatering Equipment Will Work for My Project

At Sandling Industrial Services we are often asked by our clients what sludge dewatering equipment is best for their project. In our many years of handling sludge on sludge projects, we have found that the sludge and the job goals vary widely from project to project, thus as does the sludge dewatering equipment needed to complete the work.
For instance, if the only goal is to process as much sludge as possible, high-volume sludge dewatering equipment such as hydrocyclone systems, centrifuges, thickening units, etc. may get the job done. Plate and frame filter presses, screw presses, belt presses, etc. are examples of sludge dewatering equipment that may process less galllons per minute than other styles of dewatering equipment but can yield higher “dryness” of the end solids produced, also known as cake. The ability for each type of sludge dewatering equipment to process faster or slower and at better cake solids percentage also depends a lot on the material being processed.

Sandling Industrial Services core sludge dewatering equipment solutions offered are the belt press and plate and frame filter press. Over the years we’ve found that these two types have the most flexibility in dealing with varying types of sludge while still providing production results that make sense in a project environment. For in place systems, the best sludge dewatering equipment should be identified and installed for long-term operations. For short-term projects and monthly rental of mobile sludge dewatering equipment, the wide range of possible applications of the plate and frame filter press and belt press serve as the best style of sludge dewatering equipment to set up as mobile systems.
Sandling Industrial Services mobile sludge dewatering equipment fleet is primarily belt press systems and plate frame filter press systems. That said, if the project calls for a different piece of sludge dewatering equipment, we do have other tools to get the job done and if we don’t have it, we’ll talk to our industry partners and help you find it. We at Sandling Industrial Services believe the best sludge dewatering equipment for you project is the one the best meets the project goals, be it dryness of cake, speed of production, ease of operation, or all of the above.

BP16_1.7m Roediger refurbish

The refurbishing of our 1.7m Roediger unit is nearing completion. The press has been gone through inclusive of roller re coating and  bearing replacement, even a new paint job!  BP16 has been a favorite of our operators and rental clients alike over the years. It is a three belt system with an independent gravity zone that allows, for some sludge streams, a quicker processing rate and better gravity zone dewatering.  Place your rental orders now for when it is ready to go to work!p1070016

Affordable and Reliable Belt Press Rentals

IMG_0355Sludge management and wastewater filtration is a dirty job, but someone has to do it. If you’re an industrial company tasked with dredging and dewatering the wastewater during a big project, a reliable belt press is required. However, the costs associated with buying and servicing your own belt press typically isn’t practical, which is where we come in.

At Sandling Inc., we pride ourselves on offering affordable and reliable belt press rentals and other dewatering equipment. There isn’t a job too big or too small that our mobile dewatering equipment can’t handle.

Use our 1.7-2 Meter Belt Presses for projects that require large volumes of sludge dewatering. A Plate and Frame Press is ideal when you want to recover the highest volume of filtrate and produce the driest cake from your waste stream.  We understand that every project has budget constraints and limitations. Our fees are affordable, so you won’t have to worry about going over budget in order to get the job done.

Another advantage of renting from Sandling Inc. – all of our mobile belt presses and dewatering equipment are regularly maintenanced and properly cared for. So you needn’t worry about them breaking down on the job.  In the event something was to happen to a piece of equipment, our team is ready at a moment’s notice to fix any issues. Let us help make your project run smoothly with dependable and reliable belt press equipment. Call us today to get started!

Belt Press Maintenance after winter

20150928_082313_resizedIt has been our experience with our mobile belt presses and assisting clients with their equipment that no matter how diligent your winterizing maintenance schedule for a machine located in the colder parts of the country are, something usually needs some attention come the spring thaw.

The freeze thaw cycle of water through the winter months can be tough on a belt press. We drain and blow down with air all the plumbing on a piece of equipment multiple times in order to try and prevent pipes breaking but there always seems to be a cracked 90 or two.  The best way to find these potential leak causing cracks and breaks is to water test your machine prior to putting it back in service.  This usually will identify any major issues.  Outside of that, pay close attention to all your lines the first few weeks of operation and be sure to have your parts inventory current for when a fix is needed.  If it gets to the point were the spring repairs are hurting production, give us a call we would be happy to help and/or send one of our mobile belt presses to help keep you going while the repairs are made!

Mechanical vs. Hydraulic Dredgers

1In general, dredges (also known as dredgers) come in two basic forms: mechanical and hydraulic. Mechanical dredges work by mechanically digging or gathering sediment from the bottom surface of a body of water, typically through use of a bucket.  Mechanical dredging takes place at the shoreline or working off of a barge and may or may not involve draining a lake.

The most common mechanical dredger is the bucket dredger, which is stationary, fixed by anchoring and moves while it dredges by winches. It features a number of buckets that fill as it scrapes the bottom. The material that is dredged is loaded in a barge and hauled away. This type of dredge rental is the most common in many industries.

Hydraulic dredges, on the other hand, work by sucking up a mixture of sediment and water (known as slurry) from the bottom surface and then transferring the mixture through a pipeline to another location. This dredge acts like a giant floating vacuum, removing sediment.

Dredges are used to move, and remove, a wide variety of materials, such as waste, gravel, trash and sediment.  Dredges help to keep canals, ports, harbors, and marinas clean. Dredges even help to restore beaches and land lost due to erosion.

Hydraulic dredging is most effective when working with finely grained material. Coarser things, such as gravel, can be handled but will put a higher demand on the pump, causing it to wear more quickly.

Are you looking to remove silt, sand, mud, and other sludge materials that has decreased your ponds capacity? Contact Sandling Industrial Services for mini dredge rental, which will help you to restore full capacity to your water source.

Dewatering 101

1.7 Meter Belt PressIf you’re in the business, you already know plenty about dewatering. But , if you’re new to the industry, or you’ve simply heard the term and are wondering exactly what it is and how it’s accomplished, allow us to give you a  brief overview.

First, to put it simply, dewatering is the removal of water. This process is used in many industries but commonly referred to in construction and wastewater when water is separated from solids through a variety of different pumping or filtering processes.

Construction dewatering involves pumping from wells or sumps to temporarily lower groundwater levels, to allow excavations to be made in dry and stable conditions below natural groundwater level. In wastewater treatment, dewatering is the part of the process where sludge is reduced in volume and converted from a liquid to a solid.

If you’re in need of mechanical dewatering equipment, trust the professionals at Sandling Industrial Services. Our mechanical dewatering systems are optimized to help you remove all types of solids from your waste water. Our belt filter and chamber filter presses utilize sophisticated methods that separate your solid and liquid phases. We have the knowledge and skills to help you get the job done. We service the entire United States, so call us today for help with your dewatering project.
