Automated, remote controlled, portable FLUMP can dredge & pump 80 cubic yards of solids per hour.
Ken Nelson, Dual Construction Company, Texarkana, Arkansas purchased a 3' Crisafulli FLUMP dredge in November 2004.
'A super product at a reasonable price.'
In his customer satisfaction survey, Ken considered important these factors important or very: 'product performance, features, price, warranty, and overall quality.'
Ken went on to say these factors were very important to his buying decision... 'knowledgeable and helpful Crisafulli sales person, Crisafulli's brand reputation, after-sale service and support, and his comparisons to products from alternative vendors.'
Ken graded Crisafulli customer service as excellent - 'employee friendliness and courtesy, product knowledge, ease of purchasing and ordering, and ease of payment.'
Policing the pit. With today`s emphasis on resource recovery, even burdensome and seemingly worthless materials are becoming increasingly valuable.
Take municipal sludge, for example. For sewage treatment facilities wrestling with the problem of sludge disposal, Liquid Waste Technology may have the answer.
The New Richmond, Wisconsin, USA company manufactures dredges and lagoon pumping equipment for sludge and sediment removal.
These John Deere diesel or electric powered `Pit Hog™` portable dredges...
Two years ago the Glasgow City Council announced a major clean-up of the Clyde as part a regeneration programme.
The clean-up was regarded as an important element in attracting tourists to the cities riverside and its continued development.
However two rivers, the Cart and Kelvin flow into the River Clyde and bring with them hundreds of tonnes of floating litter and debris right onto the riverside.
Liverpool Water Witch provided a successful solution.

ABSTRACTBureau of Tokyo Sewerage has 13 wastewater treatment plants and 82 pumping stations. In order to manage these facilities efficiently, collective operation in each treatment area is being promoted by making use of remote-control system. Promotion of remote control system leads to concentration of facilities monitored or controlled from the master facility, and, therefore, increases tasks of each operator, enhancing possibility of his human error. Also, due to pressing increase of age-limit retirees and...
In 1982, sediments contaminated with zinc, cadmium, and copper were dredged from Lake DePue in Illinois and deposited in a diked sediment disposal area (DSDA) that is flooded annually for at least three months. Data from soil and groundwater samples collected at multiple depths within and adjacent to the DSDA indicate vertical movement of the metals in the subsurface, although groundwater outside of the DSDA was not contaminated with any of the metals. Zinc was elevated in almost all of the wells inside the DSDA....

ABSTRACT
An array of three Geonics Limited EM61-MK2 metal detectors was utilized to identify subsurface metallic anomalies at the Mare Island Naval Shipyard in Vallejo, California.
The goal of the 120-acre survey was to locate anomalies indicative of ferrous and nonferrous ordnance and explosives/unexploded ordnance (OE/UXO) in dredge pond berms
with particular attention to 20 mm high explosive (HE) rounds. The array spanned a total of 3.5 meters and the centers of the units were 1.25 meters apart. Prior to...
Consider the following recent examples of pollution prevention in chemical process plants:
An Adiponitrile plant in Orange, Texas installed an inexpensive solenoid valve on the line supplying process water to flush the seals of process pumps used in intermittent service. The solenoid, which is connected to the pump control system, shuts off flush water when the pumps are not running. As a result, the plant has reduced its waste water volume by 57 million gallons per year.
The same facility upgraded the...
When properly applied, ion exchange for concentrated ion recovery is by far the best available technology. Where effluent streams can be filtered and ions requiring different regenerants can be segregated, ion exchange is usually the most cost effective and least capital intensive solution. We provide 4 levels of integration to cover most applications and capital budgets. The variations in the system configuration trade your labor and attention for our automation. As you invest capital, the cost of operation,...
Unidrive Pty Ltd undertake extensive machining operations during the production of automotive components. In the past this resulted in the generation of 20,000 litres of waste coolant every week. By implementing a coolant recovery and recycling system, Unidrive have saved approximately $179,000 per annum as a result of more efficient coolant usage and management.
Background
Unidrive Pty Ltd was established in the late 1950s and currently has a workforce of over 400. It manufactures drive assemblies and other...
Slurry phase biological treatment involves the controlled treatment of excavated soil in a bioreactor. The excavated soil is first processed to physically separate stones and rubble. The soil is then mixed with water to a predetermined concentration dependent upon the concentration of the contaminants, the rate of biodegradation, and the physical nature of the soils. Some processes pre-wash the soil to concentrate the contaminants. Clean sand may then be discharged, leaving only contaminated fines and washwater...
Introduction
The principle of electrokinetic remediation relies upon application of a low-intensity direct current through the soil between ceramic electrodes that are divided into a cathode array and an anode array. This mobilizes charged species, causing ions and water to move toward the electrodes. Metal ions, ammonium ions, and positively charged organic compounds move toward the cathode. Anions such as chloride, cyanide, fluoride, nitrate, and negatively charged organic compounds move toward the anode. The...
