Jetting/Vacuum Combination Equipment

There are many fine combination jet-vac systems on the market. Contractors use them in many different contexts, for many different kinds of applications, including municipal, commercial and industrial applications. Some common purposes for combination jet-vacs are the servicing of storm sewers, the emptying of catch basins, and grease traps, especially when heavy grit, sediment, sludge, grease, or other semi-solid and wet solid waste removal is required. Skip’s Wastewater Services takes advantage of a Guzzler jetter mounted on a GMC Top Kick with a 1-inch jetting hose, which produces 3,000 psi and a 1500 gallon water tank. This set-up seems to work great for the minimal amount of jetting that they do. According to the Guzzler website, they offer the widest range of offloading options available for industrial vacuum trucks. “Guzzler vac trucks are designed to vacuum a full spectrum of materials—from solids and dry bulk powders, to liquids, slurries, and thick sludge—in such industrial areas as cement plants, steel mills, railroads, oil refineries, chemical plants, foundries and power-generating stations.”
Russell Reid, a full-service company, has five 367 Peterbilt chassis trucks equipped with PresVac vacuum tanks that range between 3,500 gallons to 5,000 gallons on hand. The company also uses a variety of other smaller configuration machinery for servicing interior grease traps. Many of the units are equipped with vacuum tanks in box trucks and extra-long hose reels. Additionally, the company runs a number of US Jet brand high-pressure sewer jets on an F-550 Ford Chassis. For heavy duty cleaning, debris removal and industrial services the company runs 5 Vac-Con – Sewer/Jet Vac’s. Russell Reid has them mounted on Peterbilt model 348 chassis, and the units are equipped with a 3,600 CFM PD blower, and 60-80 GPM high pressure water jets. The 11 yard debris body, and front-mounted hose–reel is the company’s standard specification. These jet-vacs are definitely capable of handling all kinds of liquid wastes, especially vacuum cleaning of lift stations, ejector pits, storm sewers, catch basins, and other areas where heavy grit, sediment, sludge and additional semi-solid and wet solid material removal is needed. According to the Vac-Con website, their specialized sewer cleaning machines release water pressure of around 75 gallons per minute. “The water begins to flush out all the debris lodged in the pipe. Everything from stones and bottles to grease, sludge and grime get washed away. The air vacuuming system also comes into play at this point and sucks all the dislodged debris and forces it into disposal bins.”
Every day restaurants, schools, universities, prison mess-halls, hospital kitchens, and other food processing establishments produce tons of fat, oil, and grease, called FOG in the wastewater industry, that all needs to be collected, stored, disposed of, or recycled into reusable product. In addition to cooking oils, fats, and grease, FOG bearing materials also include lard, butter, shortening, margarine, tallow, a form of rendered beef or veal fat, as well as the water used to wash kitchen equipment and floors. Because of its organic nature, FOG is not your ordinary waste product. To deal with FOG on a daily basis, a company named GTO, or “Grease Traps Only,” working out of Philadelphia, PA, operates a 2008 International with a 4000 gallon tank. They also have on hand an additional 700 gallon tank to support their high-pressure jetting unit on that truck. On the truck is 250 feet of Jetter hose.
With offices across the United States and Canada, Jack Doheny Companies offers the Vactor 2100 series combination sewer cleaner, which combines high-pressure water jetting to scour pipes clean and a high-flow vacuum source to vacuum and dispose of the material that can cause blockages. This helps restore and maintain normal sewer flow crucial to anyone’s waste management needs. According to their website, “all Vactor Combination Sewer Cleaners feature the…Vactor Jet Rodder water pump with jack-hammer action to provide smooth water flow and the power needed for effective sewer line cleaning. In addition there is the optional vacuum sources of either a Centrifugal Compressor (Fan) or Positive Displacement (PD) depending on the application of use. With the Modul-Flex design as well, multiple-sized debris tanks from 3 to 15 cubic yards and water tank capacities from 500 to 1,500 gallons are available.”
No matter what your needs, you are sure to find the right jet-vac combination equipment to suit your budget and your requirements.
