Sludge mixing
Litzler Environmental offers the patented HR-5000 mixing gun for use in anaerobic digesters. The guns feature a gas bubble generator mounted to the stackpipe for maximum mixing. A gas supply line is attached to an external compressor that releases gas under pressure into the interior chamber. Continuous large gas bubbles are generated to propel sewage sludge upwards for circulation, mixing, and digestion. Sludge passes only through the pipe thus eliminating ragging and fouling of the mixing gun.

Filter press
EA Series filter presses are among the most efficient means of liquid/solid separation through pressure filtration, either for solution filtration or sludge volume reduction. Compressing and dewatering solids into cakes of 25-60% total concentration, they incorporate all the features of the company’s stainless steel presses, without the cost. EA Series presses include full thickness and height, tee-slotted, steel sidebars with stainless wear strips. Slide heads ride on full size roller and bearing assemblies. Skid shoes and pads are not used on any EA Series press.

Sludge detector
The Pulsar SludgeFinder is a reliable liquid/sludge interface detector used widely in clarifiers. It eliminates the need for operators to manually check the interface several times a day. The unique mounting bracket allows for the submerged transducer to rotate out of the water as the rake comes around and then settle back. The transducer comes with a Wiper Blade to self-clean the face every 15 minutes. The system will monitor up to four different points giving a substantial cost savings.

Bioaugmentation
The ability of a wastewater treatment plant to nitrify ammonia-containing wastes can be adversely affected by cold weather. In one mid-Atlantic state, a 3-mgd municipal treatment plant receiving high volumes of industrial and food-processing wastes began to exceed 3 mg/L nitrogen content permit limits when lagoon temperatures fell to 10°C.

Influent evaluation
Determine biotreatability of any influent wastewater stream in 10-15 minutes with a simple respiration test performed by the Arthur Respirometer. The instrument simulates full scale treatment plant activity and conditions exactly, acting as a benchtop activated sludge plant. Besides toxicity and treatability, the test will also determine the concentration for treatment of inhibited wastewater that will have no effect on the wastewater plant’s microorganisms.

Dewatering system
Super Products has added the Super Pak Dewatering system to its Camel line of Sewer and Catch Basin Cleaners. Super Pak allows the operator to compress the payload inside the debris body using the Camel’s patented pusher plate to squeeze water out of the payload allowing the operator to take a dry load to the dumpsite, which saves money on disposal costs. It also increases productivity and saves time by removing the excess liquids; the unit can stay on the job three times longer and reduces the trips to the dumpsite.

Pumps, mixers
The long-life silicon carbide seals used in Wilo EMU pumps and mixers have repeatedly demonstrated an ability to last 15-20 times longer than ordinary carbon-ceramic seals (and 2-½ to 3 times longer than tungsten carbide materials). This is particularly important because seal failure of any kind - particularly in tough pump and mixer applications - usually results in extensive damage to motor windings, motor bearings, as well as other internal components.
