Keeping grease from building up and clogging drain lines can be an ongoing problem as well as a source of additional income. Collection and separation systems can turn fats, oils and grease into liquid gold when sold to fuel processors. Scheduled maintenance programs, including the addition of grease-eating microbes, also can provide an extra source of income for your septic pumping business. Here are a few products to consider when looking to expand or update your grease handling service.

Dewatering systems

Aqua-Zyme Disposal SystemS

The ADS 30-yard (15-yard available), open-top, roll-off dewatering unit from Aqua-Zyme Disposal Systems can be filled with 22,000 to 25,000 gallons of wastewater treatment plant sludge, septic and/or grease trap waste at 1- to 2-percent solids in about two hours. After draining for 24 hours, the unit can be hauled to a landfill or composting facility for disposal. Sludge volume is reduced by up to 80 percent with reductions to 90 percent in BOD, COD, fats, oils and grease and TSS. Effluent is clear and sewerable. The unit has few moving parts. Filter media is warranted for five years. Standard equipment includes roll-over tarp system; sliding aluminum splash guard; side, floor and center screens; 1/4-inch floor plate; 7-gauge side plates; four door binder ratchets; eight drain ports with camlock fittings; two inlet posts, and a long-handle scraper. Average lifespan is 12-14 years. Units can be hauled with a standard capacity roll-off truck. 979/245-5656; www.aqua-zyme.com

Fournier Industries

The rotary press dewatering system from Fournier Industries is designed to handle municipal sludges, industrial sludges and grease trap waste. Sludge is introduced to the system under constant pressure, dosed with polymer and passed through a variable speed flocculator. Sludge then enters the circular dewatering channel through fine mesh screens. Dry cake exits the press and drops into a collection bin or is conveyed for disposal. Once the dewatering cycle is complete, the press goes through a wash cycle once per day for five minutes to maintain the machine. The enclosed press eliminates the need for odor control and can be expanded from one to six channels to accommodate increased flow rates. The press requires little operator attention and can achieve a volume reduction of up to 90 percent on grease trap sludge. 418/423-4241; www.rotary-press.com

Prime Solution

The Rotary Fan Press from Prime Solution uses continuous pressure differential technology to dewater sludge and slurries. The unit's slow rotational speed (less than 1 rpm) offers semi-automated operation. Features include self-cleaning, low maintenance, port-ability and minimal footprint. Few mechanical parts and slow rotation also reduce noise and vibration and improves the lifecycle of the machine. Available in several capacities, the unit's compact design allows for easy installation. Skid-mounted systems (trailer mounted available) include central operator control panel, feed pump, polymer system and inline mixing. Plant integrated controls are available. 269/694-6666; www.psirotary.com
