The combination of a wide variety and well-maintained rental equipment packages and the highest degree of applications expertise are the best reasons for choosing Langley Separation and Process for all your mobile dewatering and dewatering equipment rentals.

Mobile Screw Presses / Rental Screw Presses

A screw press separates liquids from solids by continuous gravitational drainage. Screw presses are often used for materials that are difficult to press, for example those that tend to pack together. The screw press squeezes the material against a screen or filter and the liquid is collected through the screen for collection and use. The specific details of the design of a screw press depend on the material. The length and diameter ratio of the screw press also depends on the material. Our rental screw presses feature stainless steel wetted parts and the screen casing is split to simplify screw removal and minimize footprint requirements. Perforated screens allow for tight tolerances and improved performance over wedge-wire screens. Low wash water requirements with cleaning cycles typically performed once per day for 3–5 minutes, and dewatering operations do not need to be suspended during cleaning.

Plate & Frame Filter Presses / Filter Press Rental

Langley Separation and Process has a good assortment of the Evoqua filter presses for rental from 2 cubic feet up to the 100 cubic feet trailer mounted units. In addition to the filter press, we can provide feed pumps and secondary conveyors and will provide start up assistance, operator training, chemistry selection and filter cloths as needed. We also work directly with Evoqua to coordinate rental equipment while new equipment is being manufactured.

Mobile filter press

The filter press is a batch operation that separates the water from the solids by a series of filter plates to separate water from the solids. The sludge feed slurry is pumped into the press and is distributed through a series of hollow filter plate frames fitted with filtering cloth and / or pre-coat filter media which captures the sludge and squeezes the water from the solids. The water is discharged from the filter press as the suspended solids accumulation becomes thicker, the filter resistance increases. Suspended solids accumulate between the hollow plate frame until fully loaded then by pulling the plate and frame filter press apart the dewatered solids cake falls off from those plates and are discharged into a pan and augered into a hopper or truck for transfer to landfill or other disposal site.

Rental Belt Presses / Mobile Belt Presses

The belt press continuously separates the water from the Biosolids by a series of rollers to separate water from the solids. The sludge feed slurry is pumped into the belt press and is fed along a belt as a series of rollers press the water from the sludge. The water is discharged into centrate pan and the dewatered solids are augered into a hopper or truck for transfer to landfill or other disposal site. Our mobile and rental belt presses are a great option for many applications.

Decanter Centrifuges Rental / Mobile Centrifuges

The decanter centrifuge continuously separates the water from the solids by high revolution to separate water from the solids. The sludge feed slurry is pumped into the centrifuge where the scroll and the bowl are operating at a high revolution creating centrifugal that separates the water and solid phases. The water is discharged into a centrate pan and the dewatered solids are augered into a hopper or truck for transfer to landfill or other disposal site. Our mobile and rental centrifuges are a great option for many applications.
