Dynamic Dewatering

ABCO Industries Ltd.

The self-contained mobile dewatering truck from ABCO Industries Ltd. is made for dewatering municipal and industrial sludge. Incoming sludge is conditioned with polymer and an onboard filter system separates solids and liquids. Solids are stored in a holding chamber on the truck, while liquid and useful bacterial are returned for normal on-site treatment. Dewatered material can be disposed of at an approved compost-receiving site, eliminating the lagoon disposal cost. Transportation costs also are reduced. The dewatering truck is equipped with a high-pressure jetting system for cleanout and can be used as a conventional vacuum truck. 902/634-8821; www.abco.ca.

The rotary fan press from Prime Solution Inc. features continuous pressure differential technology to dewater sludges and slurries. Features include slow rotational speed (less than 1 rpm), enclosed, automated, low maintenance, portable, space-saving and expandable system. Conditioned sludge is fed into the enclosed, slow-moving dewatering channel between two parallel stainless steel wedge wire filter plates. The feed sludge is subject to a pressure drop where liquids pass through the filter openings and solids advance within the channel. Sludge continues to dewater as the feed pump supplies more sludge, slowly moving the solids through the channels toward the outlet of the press, forming a cake. Units can be expanded up to four channels with capacities of 260 gpm.

The unit can turn a mobile storage tank into a 200-gpm clarifier capable of reducing TSS concentrations below 5 mg/l. The inclined plate clarifier uses counter-current flow for effective solids separation. As water flows upward, solids settle on the plates and slide into the belly of the frac tank. Directing influent into the side of the unit ensures even distribution across the entire plate. Orifice holes in the effluent weirs provide backpressure to ensure even distribution across the inclined plate. An optional influent feed pump is available. The stand-alone module can be shipped inside the mobile tank or inserted on site. 877/864-7873; www.unipure.com.

VerderGPM

Only the hose is in contact with the pump media. The hose has a resilient inner core of thick, soft rubber and harder outer covering with braided nylon reinforcement. It can withstand pressure up to 230 psi. The inner core also acts as a cushion to abrasive solids trapped during compression, reducing abrasive wear. The self-priming pumps are seal-less and can run dry without damage. 877/476-3569; www.verdergpm.com.

Wastequip

WesTech Engineering

The WWETCO FlexFilter from WesTech Engineering is a gravity system and requires no moving parts. It uses a synthetic compressible media to capture solids in a high-rate filtration process. Influent liquid applies a hydrostatic force to a flexible bladder causing media to compress. The tapered compression provides for a densely compressed media bed at the bottom of the filter that graduates to an expanded bed toward the surface. As liquid flows onto the top of the media, larger particles become trapped in the upper portions of the filter. Smaller particles are captured as the liquid works its way down through the media. In addition to being able to handle higher solids loading, the filter has a backwash system that uses an air scour with high-energy wash cycle and specialized backwash troughs to minimize the amount of backwash water needed. 801/265-1000; www.westech-inc.com.
