Equipment used to handle grease, including dewatering units, containment tanks, chemical and bacterial additives and interceptors help keep grease in check and drainlines open. Preventing grease buildup and clogging lines can be an ongoing problem, as well as a source of additional revenue. Here are some products to consider when looking to service grease traps.
GREASE HANDLING EQUIPMENT
Roll-off dewatering unit
The ADS 30-yard dewatering unit from AQUA-Zyme Disposal Systems can be filled with 22,000 to 25,000 gallons of liquid waste at 1 to 2 percent solids in about two hours. After draining 24 hours, the unit can be hauled to a landfill or other permitted facility for disposal. Sludge volume can be reduced by 80 percent, with reductions to 98 percent in BOD, COD, FOG and TSS. Effluent is clear and sewer-safe. The unit has few moving parts, and includes a roll-over tarp system; sliding aluminum splash guard; side, floor and center screens; 1/4-inch floor plate; seven-gauge side plates; four door binder ratchets; eight drain ports; two inlet ports; and a long-handle scraper. The average life span of the unit is 12 to 14 years, and it can be hauled with a standard capacity roll-off truck. Units are also available in a 15-yard size. 979/245-5656; www.aqua-zyme.com.
Secure grease containers
High-security steel grease containers from Bakers Waste Equipment incorporate several features that lock down the container lid and prevent theft of cooking grease for bio fuel conversion. The all-steel container lids also include high-security dump screens for filtering solids and preventing unauthorized pumping of the grease through the dump port. They are designed for pumping or dumping collection. 800/221-4153; www.bwe-nc.com.
Flat grease storage tank
The Model 1600 flat storage tank from Crescent Tank reduces the need for separate pickup/delivery and service vehicles, which in turn saves on fuel, insurance, payroll and maintenance costs. It features a lift gate, which allows the driver to place 55-gallon drums on the deck. The waste tank capacity is 1,600 gallons. In colder climates the waste tank deck will haul 55-gallon drums. If waste oil is too thick to vacuum into the tank, simply swap out the drums at the customer’s location. 585/657-4104; www.crescent-tank.com.
Grease waste processing system
The SM BG 10,000 Series GREASEZILLA from Downey Ridge Environmental comes preassembled, allowing for quicker onsite installation and startup. It processes concentrated raw trap waste into a marketable commodity – a clean product that features moisture content of less than 1 percent. Its hydronic heating system burns brown grease, the petroleum-free, green, renewable biofuel it produces. The system can be accompanied by two 10,000-gallon double-walled process tanks built with a 3-inch interstice filled with a poured insulation, resulting in efficient heating and code compliance. The control panel requires 120-volt power. 304/658-4778; www.greasezilla.com.
Indoor containment system
The indoor containment system from Envirotub is made from recycled plastic that eliminates grease buildup and allows for easy cleaning. The system measures 18 inches wide, 32 inches high and 28 inches long, enabling it to fit under most two- and three-compartment kitchen sinks, and has four cast-iron wheels with optional locking. The top of the system has a raised edge to contain overflow and spillage and is designed to drain spilled grease or fryer oil toward the opening. The 12-inch lid seals to prevent odors and is vented in the center to allow heat to escape and prevent expansion. The unit can hold up to 55 gallons (400 pounds) of waste and withstand oil temperatures up to 190 degrees. The tub can be pumped out in 60 seconds or less. 866/777-4322; www.envirotub.com.
Sludge Mate container filters from Flo Trend Systems can dewater a variety of sludge and wastes such as alum, ferric, lagoon dredgings, digested sludge, septic tank and grease trap waste, wastewater residuals and sump bottom materials. The closed system design provides odor control, no spillage, reduced maintenance and weather independence. Units have 10-gauge reinforced walls and seven-gauge carbon steel floors. Available designs include peaked roofs with gasketed bolted-down access to hatches, drainage ports, inlet manifolds, floor filters and side-to-side rolling tarps. They dewater on site and are available in roll-off, trailer-mounted and tipping-stand-mounted styles and in sizes from 5 to 40 cubic yards. 713/699-0152; www.flotrend.com.

Bacteria/Chemicals – Grease
Grease trap maintenance solution
The DrainMaster grease trap and drainline maintenance system from Cape Cod Biochemical Co. can eliminate sluggish drainage, overloaded grease traps, odor, slow running plumbing and waste lines, backups, contaminated septic systems or sewer plants, grease disposal problems and regulatory problems. It is a scientific formulation of specific enzyme-producing bacteria that will digest grease, oil, protein, starch, fat, carbohydrates and cellulose that commonly build up in drains, pipes and waste lines. The process utilizes a simple, timed metering pump to inject a precise daily dosage into the grease waste system. The peristaltic pump is easy to install and service, and economical to operate. 800/343-8007; www.septiconline.com.
Bacterial waste degrader
Specially formulated for direct addition to drains and grease traps, bioForce Plus bacterial waste degrader from Chempace Corporation is a blend of bacillus strains cultured for their ability to digest all organic waste. It also contains cellulose that works to quickly break up grease, fat, starch and carbohydrates, reduce sludge buildup and lower BOD in the effluent wastewater. When added during the time when drains are the least active, it establishes a strong bacteria population that continuously works to keep drainlines and grease traps free flowing. Regular injections are recommended to maintain peak effectiveness and control odors. 800/423-5350; www.chempace.com.
Septic/grease treatment and cleaner
Drainbo septic treatment and cleaner is a bacillus-based cleaner that treats all drainlines, increases digestion in the septic tank or grease trap with a seven-strain formula, and digests and removes sludge deposits in the leachfield, allowing liquid to disperse and evaporate. It is certified by the Natural Products Association. 877/372-4626; www.drainbo.com.
Liquid live bacteria treatment
PRO-PUMP/HC liquid live bacteria from Ecological Laboratories are a blend of microorganisms selected for broad-spectrum application in industrial and wastewater treatment. It contains over 30 strains of bacteria that rapidly break down and remove fats, oils and greases that build up in drainlines and grease traps, treating line blockages, surface solids, bottom solids and grease blocks. It will also degrade long-strain fatty acids, reducing grease trap odors. Treatment reduces trap surface solids, making pumpouts more cost-effective. 800/326-7867; www.propump.com.
Bacterial grease consumer
GES Plus from Environmental Biotech International is an environmentally conscious product that eliminates grease blockages permanently. It harnesses the power of nature in a process in which specifically developed bacteria consume grease and oil from drainlines, grease traps, pump stations, septic tanks and anywhere else grease creates problems. These bacteria are nontoxic, nonpathogenic, live and highly active. They turn grease and oil waste into carbon dioxide and water. The product contains a powerful odor treatment to eliminate rancid odors, leaving the drainage system smelling fresh and clean. 800/314-6263; www.environmentalbiotech.com.
Grease trap repair treatment
Earth Works Water Treat GT from Green Way Products by PolyPortables is a ready-to-use all-purpose treatment for repairing and maintaining grease traps, septic systems, drainfields and wastewater holding tanks. It combines two natural technologies to control odor, reduce fats, oils and grease, reduce corrosion and promote healthy wastewater containment systems. The primary active ingredient, Histosol, is organic, and binds up hydrogen sulfide, mercaptans and ammonia to reduce odor. Selective bacteria strains are added to break down grease and waste, and reduce suspended solids. It also reduces rancid odors associated with grease traps. For poorly maintained solidified traps, pretreat traps 48 to 72 hours before pumping to reduce odor and speed pumpouts. It will also condition the inside of a pump truck’s holding tank while enroute, reducing foul tank odors. It comes in a variety of fragrances in 1-, 5-, 7- and 55-gallon containers. 800/241-7951; www.greenwayproducts.net.
