What is sonic drilling? Sonic drilling is a technique that significantly reduces friction on the drill string and drill bit by using energy resonance to affect the soil structure where it contacts the drill string. This combination makes penetrating for a large range of soils much easier. Sonic drilling is most often used when the drilling is difficult and the integrity of the core sample is ...
Pickard Environmental Centre (ROPEC) in Ottawa, Canada was undergoing needed upgrades and expansions to its thickening and dewatering building. This building plays a vital role by in water treatment providing sewage receiving and pumping, sludge mixing and thickening, as well as dewatering digested biosolids. ...
The filter resistance increases as well, and the process is stopped when the pressure differential reaches a point where the plates are considered full enough. YASA ET Plate And Frame Filter Press Applications Filter presses are used in a huge variety of different applications, from dewatering of mineral mining slurries to blood plasma purification. At the ...

There are many different ways to remove debris from a construction site, but not all are effective and efficient. Whether you are a homeowner taking on a do-it-yourself renovation, or a contractor working on commercial building remodels, one of the best options for taking car of the mess left behind after a big project is a roll off dumpster rental service. In addition to clearing construction ...
In this blog, we will discuss the advantages of further sludge dewatering, as well as the technologies behind this important process. Why Is Sludge Dewatering Necessary? Sludge dewatering is a reliable and efficient method of concentrating waste into high solid filter cakes, thus making them significantly easier to dispose of. ...
We have a large number of lakes and waterways in the United States, plus a lengthy coastline as well. That means a large expanse of shorelines, which in turn means a hefty need for construction in and around shoreline areas. ...
THE SOLUTION The required excavation for repair on the downstream toe drain was 80 ft. deep. Griffin designed a dewatering system using deep wells, eductors, and wellpoints to control groundwater and allow construction on the dam to be conducted safely and efficiently. ...
Abstract: The challenges of mining economically have never been greater than under current global financial conditions. The costs and efficiency of dewatering are particularly important at De Beers Canada’s Victor diamond mine in northern Ontario where: the bottom of the water-bearing carbonate country rocks is near the bottom of the planned pit, limiting the available ...
In many surface coal mine settings, these sediments are saturated; and prior dewatering of them is necessary for effective and economic mining, including the stacking of saturated spoils. ...
This project involved simulating mine dewatering and excavation to evaluate future dewatering requirements, as well as providing guidance for future monitoring borehole and piezometer designs. ...
This project is next to the Mississippi river, and required a large volume of groundwater to be pumped. THE SOLUTION A temporary dewatering and depressurization system was required for the excavation to proceed in a safe and efficient manner. Griffin installed 30 wells to dewater the 36-inch sanitary sewer line that runs west/east through the ...
The discharge permit obtained for this project outlined strict effluent limitations and monitoring requirements. SOLUTION The deep well dewatering system was able to provide a stable working surface and allowed the work to proceed in a safe and efficient manner. The treatment methodology applied reduced the contaminants to well below ...
What the costs are to clean-up a site via traditional vertical extraction wells versus using a horizontal well system needs to be reconsidered based upon todays remedial challenges. ...
Project Location: Hammond, IN Owner: Savage Services GC: Meyer Contracting Engineer: Savage Services Project Revenue: $225,000.00 Summary: The Transload facility remained in operation during installation of the jetted deep well dewatering system, required to install a water line, sewer line and retention basin during plant upgrades. ...
The challenge was to create sufficient drawdown without lowering the water table below the limits of nearby monitoring wells, while considering that the total discharge flow was limited by the client’s treatment facilities. ...
The "through-the-weave" production method gives a very strong bonding between cover and tube as well as firmly adhesive of the jacket. The hose has high resistance against commonly used chemicals and has excellent resistance to UV. ...

They were having trouble with the ground water contamination, possibly from the septic tanks, which was causing iron related bacteria to grow in the ground stabilisation dewatering wells. ...
One of the most difficult challenges for contractors with pump station installation projects is addressing dewatering. Romtec Utilities has experienced many projects that required dewatering, and being prepared for dewatering can be the difference between a smooth pump station installation and a problematic or delayed installation. ...
