Aerators
These aerators have the best efficiency for oxygen transfer and pumping rate capacity of any aerator on the market. These units have a certified SAE oxygen transfer efficiency of 2.8 lbs Oxygen/hp-hr in dirty water (over 5.0 in clean test water conditions). In addition and just as important is the amount of water an aerator moves. These units pump 3,500 gpm/10 hp (aspirating aerators pump 300 gpm/10 hp and mechanical splashers do 450 gpm/10 hp). The importance with the pumping rate is the contact frequency of the oxygen with the BOD and bacteria so the food gets to the bugs.
Power savings: the potential power savings yields a good payback with replacement of aerators and there is often a rebate from the local electric company to offset the capital costs further decreasing the payback period.
BioReactors
A BioReactor is a biological wastewater treatment system used to degrade high levels of BOD. This is achieved with the use of a series of tanks, blowers, and pumps that specially designed to maintain an aerobic biomass (population of bacteria that eat the organic constituents that makeup the BOD). A Bioreactor gives industry an option to treat BOD in an economical and reliable manner.
Packaged 1,500 gpd unit
The BioReactor can decrease BOD 80-98% and has an estimated area footprint of 36-45 square feet per 1,000 gallons of water treated per day. It basically runs itself. Maintenance is 20 min/day; the pH controller needs calibrating, the return sludge needs to be monitored, and the solids coming off the screen need to be managed. Operational costs depend on the size of the system. Costs include electricity, chemicals and labor which averages $0.002 per gallon treated or $0.04 per pound of BOD reduced.
Small 25,000 gpd facility
A BioReactor starts by screening out all of the larger particulates. The wastewater is flow equalized and pH adjusted to 7-8 in an equalization chamber. Aeration starts in the following chamber where blowers supply air as well as mixing energy to the wastewater. The BOD levels are reduced as the bacteria ``eat`` the BOD. A clarifier follows the aeration chamber where the solids settle to the bottom, and get returned to seed`` the incoming wastewater with healthy bacteria. The clarified effluent then flows out of the BioReactor. Depending on the site requirements, the treated water can be used for irrigation, land applied, water-reuse, or discharged to the Publicly Owned Treatment Works (POTW)
Medium 60,000 gpd facility

Aeration starts in the following chamber where blowers supply air as well as mixing energy to the wastewater. The BOD levels are reduced as the bacteria ``eat`` the BOD.

The clarified effluent then flows out of the BioReactor. Depending on the site requirements, the treated water can be used for irrigation, land applied, water-reuse, or discharged to the Publicly owned Treatment Works (POTW)
Clarifiers
This unit is a Lamella plate clarifier with a design rated at 125 gpm for use in a Bioreactor system. It is used for clarification of bio-solids prior to discharge to the fields. The clarifier included dual mixing chambers for addition of a coagulant and then a flocculant for settling aids used during start up of the aerobic biomass or system upsets from the plant sanitizing operations, etc.
Filter Presses
No matter what size filter press you are interested in -- new or used. Whether it is one item or part of a complete package, we can find the items for you. If you are looking for a small unit such as the 1 cu ft for a smaller industrial setting or if you are looking for some thing a little larger. Manual or fully automated we will help you select what is right for your setting and budget.
Rotary Screens
Features of the Integrated Engineers Internally-fed Rotary Screens
Integrated Engineers Internally-fed Rotary Screens use a cylindrical drum mounted horizontally on four shaft mounted trunnion wheels that are supported on pillow block bearings. The rotating screen is slotted wedge wire screen with sized ranging from 0.075 to 0.010-inch openings. Rotary Screen sizes range from 1`-6`` long and 1`-6`` in diameter to 8`-0`` long and 4`-0`` in diameter. Flows are dependent on rotary screen open area and size.
Method of Operation
The influent enters a collection/diversion box, which extends 2/3 the length of the drum, where the flow is evenly distributed onto the sidewalls of the drum. Solids are retained on the rotary screen surface as the liquid flows by gravity through the rotating screen openings. Splashguards direct the liquid filtrate to a central drainage area, and the solids are transported axially, by flights, to the open end of the drum. The rotation of the drum allows the entire screening surface to be continuously or intermittently washed by a fixed external spray bar fitted with a bank of fanjet, spray nozzles.
Materials of Construction
- All 304 stainless steel construction including the frame, legs, drainage pan, discharge chute and screen
- Channel base in 304, stainless steel
- TEFC motor and gear drive
- Stainless steel, direct drive wheel
- UHMW polyethylene trunnion shaft mounted on pillow block bearings
- Internal flights
- External spray bar with optional reuse pump/filter
- Nema 4 Control panel /w starter and spray bar timer. Spray bar has delay off time to fully rinse the screen prior to shutdown.
