Contract ServicesRemote access or site visits are available. Daily, weekly or monthly visits include pump testing, float testing and control testing in a variety of methods. Routine visits or remote monitoring can be the least costly method of maintaining a lift station and avoiding fines or penalties due to failure and overflow.Repair & MaintenanceEmergency ResponseOdor ControlIn the wastewater industry, there are hundreds of different products, equipment packages and methods of odor control. Keeping odors to a minimum at collection stations, lift stations and treatment plants can be vital to keeping neighbors happy and meeting DEP requirements. Odor control can also be closely related to maintenance and repair costs.
As operators, ESI controls odors in wastewater systems (lift stations to effluent stations) often with added benefits of enhanced treatment processes and limited, or even lowered, wasting needs.Grease Removal and ControlWhy is grease a problem? Are there alternatives?
Grease is a problem and can be costly for multiple reasons:
Grease build up can accumulate inside a lift station. Lift stations often use float balls that activate pumps when they turn up as the lift station fills up with sewage. Float balls can fail to turn and activate if grease accumulates on them. Transducers (measure pressure) can also be used in larger lift stations to activate pumps measuring pressure as the station fills up and sending a signal to turn pumps on. Transducers have pressure plates that do not act correctly if covered by grease. When a lift station fails, back-ups can occur, sewage spills can result around the station, and more. Grease build up on control equipment like float balls can even prevent a float ball from de-activating causing the pump not to shut off when needed and burning up expensive equipment and potentially causing an expensive emergency repair.
Oil and grease also hamper effective treatment at the wastewater treatment plant. Grease is the number one cause of treatment plant foaming and solids bulking. FOG (Fats, Oils and Grease) is expensive to treat once it reaches the treatment plant. Additional air and retention times are needed raising the cost of treating each gallon of sewage.
Grease and fats stink. Their odor is obnoxious at best. Accumulations in manholes or lift stations, oil and grease also hamper effective treatment at the wastewater treatment plant. Grease is the number one cause of treatment plant foaming and solids bulking. FOG is expensive to treat once it reaches the treatment plant. Additional air and retention times are needed, raising the cost of treating each gallon of sewage.
FOG is a major contributor to low dissolved oxygen (D.O.) levels in collection systems, manholes and lift stations. As D.O. levels go down, anaerobic bacteria grow (just like in a septic tank and drainfield). The problem is the types of bacteria that grow in this environment release odorous and toxic gases. These gases also have detrimental effects on concrete and metal. Therefore equipment, lift station piping and the holding tank itself are subject to attack. As the levels of D.O. decrease, the populations of anaerobic bacteria increase, therefore so do the detrimental effects. Many municipalities have large maintenance budgets just for lift station and piping repairs. ESI has a solution. It is a solution that not only relieves odor problems and raised D.O. thus saving these critical components; it actually lowers CBOD and TSS so the treatment plant costs are also lowered. Call us for more details.CBOD RemovalTreating CBOD and TSS at wastewater treatment plants are two of the main objectives of a treatment plant. Fats, Oils and Grease (FOG) are particularly difficult to treat due to the raised levels of CBOD and TSS inherent in their make-up. A grease trap can catch a majority of these "contaminants", but often a grease trap is not enough and higher doses of FOG are sent to the local wastewater treatment plant.
Fines from local municipalities, or DEP, due to excessive CBOD or TSS in the wastewater stream delivered to the municipal wastewater plant, can be extremely costly and redundant. New treatments are available that avoid emulsifying Fats, Oils and Grease (FOG) issues, but treat them. CBOD, TSS and turbidity reduction or removal is now possible with the right equipment and product. Most equipment for FOG reduction is bulky, costly and requires engineering design and permitting. ESI, in cooperation with manufacturing companies, has developed a method and product that may avoid all design costs and permitting fees. The product is also ADA approved, so environmental or health hazard issues are not a concern.
