Sludge can be tested for approval for land application or landfill disposal. Some sludges can be used for soil amendments as well. Sludges have been incinerated for disposal and even rarely as a feedstock for energy production.

Sand and kaolin clay are two unique types of material. Sand is much more abrasive and must be pumped with hardened steel pumps and cutterhead wear parts. Kaolin is less abrasive but must be pumped efficiently, often at long distances to be economical. Hydraulic mining is often used when the source is dry. Dredges are used when the water table is above the source of material.
Sand dredging can be done within quarries or mines for mining or reclamation purposes. Sand can be excavated with an excavator and stockpile easily as it dewaters rapidly. Pumping sand with a dredge is an effective means to move sand and process it. Sand pumps are made of specific metal to prevent wear. Pipeline is usually high-density plastic to prevent wear as well.
Cleaning out sediment ponds at a quarry can be tedious. Draglines were used in the past but have mostly been replaced by excavators to dig out settling ponds. Hydraulic dredges can also be useful to remove sediment from ponds in mine sites and quarries. Tailings, silt, and sediment can be removed and used in reclamation activities or placed in areas outside of the main processing facility.
Sedimentation is a growing problem in our lakes, ponds, and reservoirs. Removing it can be difficult. Dredging is one solution that can remove sediment efficiently and effectively. The sediment can be disposed of nearby or transported off-site. Dredging is done by either digging the sediment out or pumping it (sucking) from the bottom of the reservoir. Once sediment is within a lake, pond, or reservoir dredging is way to get it out!
A silt trap is an area designed to capture silt before it enters a pond or lake. The purpose of a silt trap is to slow the water velocity down. This will allow the silt to settle from the water before it enters the main body of the lake or pond. The silt trap should be easily accessible for periodic cleanout. Most silt traps are cleaned with an excavator.
There are a lot of products that claim to get rid of silt or muck from the bottom of your lake or pond. Some products attempt to resuspend the silt. Some attempt to re-aerate the silt. Some products try to decompose it. However, most silt removal is very limited with these techniques. Dredging is a proven solution to removing silt from your lake or pond. Dredging can be done by digging the silt out or pumping the silt from the lake or pond.
Muck can be as nasty as it sounds in your lake. The way to remove muck from your lake depends on how much you have and what kind of muck. Muck rakes can be used to clean up a small portion of muck that gathers along your shoreline or dock. Pumping muck with small trash pumps may work a little but is generally not an effective means as it stops up with sticks and trash easily. You also have to deal with the water you pump from the lake. There are some chemical and biological solutions that aid in decomposing organic matter but not the dirt portion of muck. There are even mats made to walk on it. Ultimately though, the solution to remove muck is to dredge your lake. Dredging can remove muck from any area and restore the lake back to the original depth.
Dredging is the method to remove sediment, silt, and muck from a lake, pond, or lagoon. You can dig the dirt out with an excavator, or you can pump it out with a dredge.
