This invention relates to wastewater treatment; and more particularly to a modular device and system for dispensing biological materials within a wastewater system environment.
Removal and treatment of wastewater is a major task for local governments. In the early 20th century, municipalities began to adopt biological methods that now form the basis by which wastewater treatment plants function. Microorganisms act to catalyze the oxidation of biodegradable organics and other contaminants generating innocuous by-products such as carbon dioxide, water and biomass (sludge). In these systems, bacteria grow and divide, producing biosolids and clean water effluent. Today, this metabolism occurs in wastewater treatment plants which have the limits of size, retention time, processing capacity, and municipal budgets.
Technology exists, such as that described in U.S. Pat. Nos. 5,578,211 and 5,788,841 and commercialized by In-Pipe Technology Company, Inc. (Wheaton, Ill.) to effectively enhance the fundamental wastewater treatment process by starting treatment at strategic locations throughout the sewer collection system. Miles of sewer pipe are transferred into an active part of the wastewater treatment process, optimizing the entire infrastructure. This improves operating economics without additional capital expenditure. Since it uses natural, biological methods that work with the treatment plant's own processes, such technology is an environmentally and economically sound sustainable solution. However, maintaining bacteria concentrations at proper levels is a significant cost associated with systems employing the '211 and '841 patents.
Thus, what is needed in the art is a device that dispenses biological solutions into a wastewater treatment environment which reduces overall costs associated with delivery of the microbial agents into the system.
The instant invention describes a device and system for dispensing biological solutions into a wastewater treatment system containing a biological dispensing unit located within the wastewater environment, such as a sewer system, remote programming devices, and a main control device located remotely from the dispensing unit. The dispensing unit device contains one or more removable modules that provide the user with the capability of quickly and easily removing biological solutions stored within, without the need for replacing or removing the entire unit. The modules are preferably designed to hold bags filled with biological, i.e. microbial, solutions. The bags are fluidly connected to at least one material delivery unit which includes a pump to dispense the solution to a predetermined location through one or more tubing.
Accordingly, it is a primary objective of the instant invention to provide a modular smart device and system for dispensing biological solutions into a wastewater treatment environment.
It is a further objective of the instant invention to provide a system using a modular smart device for dispensing biological solutions into a wastewater treatment environment.
It is yet another objective of the instant invention to provide a modular smart biofeeder device and system which can be controlled remotely.
It is a still further objective of the instant invention to provide a modular smart biofeeder device and system which operates with wireless technology.
It is a further objective of the instant invention to provide a modular smart biofeeder device and system which minimizes costs associated with supplying a bacterial solution to a particular environment.
Other objectives and advantages of this invention will become apparent from the following description taken in conjunction with any accompanying drawings wherein are set forth, by way of illustration and example, certain embodiments of this invention. Any drawings contained herein constitute a part of this specification and include exemplary embodiments of the present invention and illustrate various objects and features thereof.

Positioned on the upper surface 44 of the base 20 is a second module securing member, illustrated herein as cylindrically shaped plug members 46 and 48. Each of the plug members 46 and 48 is constructed and arranged to provide secured mating with a portion of the removable modules 14 and 16. The plug members 46 and 48 may be solid, or alternatively may contain an opening 50 which exposes an internal cavity. The plug members 46 and 48 may contain a rimmed or lipped outer surface 52 to provide a friction or snap fit connection to secure the removable module 14 or 16 to the base 20, thereby preventing both lateral movement and horizontal movement. The rimmed or lipped outer surface 52 is constructed and arranged to prevent the modules from upward and/or side-to-side movement while allowing the modules to be detached under a sufficient predetermined force.
The back surface 54 of the main dispensing unit 12 contains opening 56 which exposes an interior compartment 58. The interior compartment 58 is constructed and arranged to hold a variety of hardware to provide the device with fluid dispensing functionality.

By providing individual modules 14 or 16, the biofeeder device 10 is designed to be placed within a particular environment and remain in place over an extended period of time. When the contents of the modules have been depleted, the user retrieves the module from the main unit 12, removes its content, and replaces it with new materials. The module is then secured to the main unit 12. This is accomplished without the need to remove the entire device 10. As an illustrated example, the biofeeder 10 is placed in a wastewater environment, such as a sewer pipe where its primary function is to dispense fluid, i.e. a biological solution, preferably a bacteria solution having one or more strains of bacteria, to the pipes, thereby providing a bacteria flora that helps increase the efficiency of the wastewater treatment plant and extend the life of existing infrastructure. The biofeeder 10 is designed to attach to existing structures within any environment. In the sewer pipes, the biofeeder device 10 may contain a securing bracket 140, see
The bracket 140 contains a first end 142 constructed and arranged to contain a first mechanism 144, illustrated as a generally u-shaped member, for attaching or hooking onto an existing structure within the environment, such as but not limited to a ladder rung 146. Such ladder rungs are typically located within sewers and are used to provide city workers a means of accessing the sewer system. A second end 148 contains a second mechanism 150, illustrated as a generally u-shaped member (the u-shape formed in the opposite direction as the first mechanism 144) for attaching or hooking onto adjacent or other ladder rungs 152. The second mechanism 150 is preferably spring loaded so that it may move in an upward direction, see arrow 154, or downward direction depending on the distance between adjacent ladder rungs in order to connect to ladder rungs that are not uniformly spaced apart.
Alternatively, the biofeeder 10 may be secured to the opening 155 of a sewer system manhole 156, see
Regardless of the mechanism of attachment to the sewer system, the biofeeder device 10 functions primarily to dispense predetermined amounts of the bacteria solution into a precise location within the sewer pipe at predetermined times. The bacteria solution 110 placed in the bag 108 and stored in the removable module 14 is fluidly connected to the pump 60 through tubing 68, see
The biofeeder device 10 is preferably powered using rechargeable batteries generating 12V to drive the pump 60. The battery voltage is monitored by an A/D input on the microcomputer 64. Battery level indicators are included to visually indicate if proper charge on the battery remains. Real time monitoring of the battery life can be kept through the use of a RTCIC. If the battery or the biological solution must be replaced, the user retrieves the removable module 14 or 16 from the base 20 by inserting a retrieving device 200, illustrated herein as a hook, see
The present invention also contemplates the use of a plurality of biofeeder dispensing units within a wastewater treatment system to provide for a system for dispensing biological solutions into a wastewater system. Each of the biofeeder unit 10 may be in communication with one or more independently functioning biofeeder units within the system, as well as with one or more main computers which function to monitor and provide instructions for the entire system. By placing a plurality of biofeeder devices 10 within the system, a large area of the wastewater system can be controllably dispensed with one or more types of microbes or bacterial solutions. For example, one biofeeder device 10 may contain a bacterial solution having a single bacterial species. A second biofeeder device 10 within the system may have a bacterial solution with different species. For example, the system may include 5 biofeeder units 10 having Bacillus concentrations at high and low concentrations, 3 biofeeder units that dispense heavy grease bugs (HGB) to remove fats, oils, grease (FOG) concentration, and two biofeeder units 10 in specific locations dispensing different consortium of microbes for heavy load problems. Such system allows for delivery of microbes to different areas of the system based on residential, commercial, or industrial loading.
