ABOUT SANTEC CORPORATION Santec Corporation is a consulting and construction company specializing in wastewater treatment systems. Incorporated in 1987 by John Clingman and Dwight Zemp, Santec Corporation has established itself as an industry leader in providing technical support for small to medium scale wastewater treatment applications. Santec’s experience includes a wide range of turn-key facility designs for residential developments, large multi-national firms, the food processing industry, Federal and state governments, municipalities, and a number of other private & commercial developments. In all, Santec Corporation has installed, modified or retrofitted over 150 wastewater treatment facilities in 22 U.S. states and the Caribbean.

“We strive to provide each customer with a complete wastewater treatment solution”

Santec’s primary strength is our swift implementation of a turn-key, cost-effective technical support strategy. This involves a range of services from planning and consulting, site visits, and collaboration with engineering and design teams. Effective utilization of Santec for the wastewater technical support minimizes engineering costs, and simultaneously bolsters the overall level of expertise provided to the client by the project engineer. One of Santec’s core competencies is the result of our belief in the importance of plant operations. Santec’s on-site operations training program, process control software and follow-up tracking & monitoring program provides clear differentiation of Santec from our competition.

BENEFITS

DESIGNED SPECIFICALLY TO YOUR APPLICATION Santec’s technical support service provides a complete treatment system design tailored to the specific project requirements. Influent compositions, for example, vary with each treatment situation, requiring a system designed to those concentrations. That is why Santec does not sell pre-designed plants. Each system is individually designed, manufactured and shipped to the jobsite in modular units, ready for installation. Lift stations, headworks, disinfection and nutrient removal systems, as well as tertiary filters and other process equipment are also built to specification and shipped as modules to the jobsite.

OPERATIONAL SIMPLICITY / SUPPORT One of the primary concerns of nearly every small to medium scale wastewater treatment facility is effective operation of the plant. In fact, the Environmental Protection Agency estimates that up to 80% of small to medium sized wastewater treatment facilities are currently operating out of compliance. Santec addresses this problem in a number of important areas. First, Santec includes a three-year tracking and monitoring program with every treatment system installed. This computerized program gives Santec staff the ability to monitor plant performance on a periodic basis, and flag data that may reveal an operational or process error. Second, Santec focuses its design efforts on minimizing the overall level of operator attention required. Making all equipment and maintenance readily accessible and easily removable to the surface is one example of this design focus. Third, Santec works to preempt operational problems through providing comprehensive on-site operator training and customized operations and maintenance manuals for each facility. Fourth, Santec stresses the development of rapport with each facility operator, such that they feel comfortable asking any question. Santec is committed to establishing working relationships with each operator, under the assumption that good operator rapport translates into excellent plant performance. Finally, Santec has proven their commitment to operations support in that they contract operate a number of their own facilities. Santec also owns two utility districts which utilize Santec facilities for the onsite wastewater treatment demands.

SUPERIOR COLD WEATHER PERFORMANCE Biological reactions are approximately twice as fast at 80 F than at 35 F. Clarifiers, in particular, are more effective when the mixed liquor is warm. At 80 F, the rate of particle settling is 50% greater than the rate at 50 F. Efficiency and reliability, therefore, can be seriously affected if fluctuations in ambient temperatures are allowed to effect the temperature in the treatment process. Heating and insulating equipment can be added to other treatment process designs, but at a high level of additional expense. Santec’s underground, totally enclosed designs simply utilize the insulation provided by the natural ground to maintain consistency of temperature, enhancing treatment and clarification efficiency.

MINIMIZATION OF SLUDGE HANDLING Sludge management is often identified as one of the most persistent problems in small, mechanical plants. The key to minimizing sludge is the system design’s ability of converting the particulate portion to a soluble form. When the biomass consumes organic material in a soluble form, there will be approximately 50% less biosolids and waste sludge. This is due to the more complete and more efficient utilization of the organic material by the organisms and the reduction of particulate material left over at the end of the process. Santec designs achieve this by enhancing the solubilization of colloidal and particulate organic matter. This occurs in reactors designed to retain particulate matter in an environment that is substrate limited long enough to solubilize it into low molecular weight soluble compounds. As a result, solubilization occurs as extracellular enzymes are excreted into the aqueous liquid, hydrolyzing the colloidal and particulate organic material. Once this solubilization occurs, the biomass converts it to carbon dioxide and water, resulting in more efficient consumption of biosolids. As an appurtenance, Santec also offers a sludge drying and bagging unit. This unit automatically compresses and packages the sludge generated from the process into porous bags, which subsequently can be tested and approved under EPA guidelines for landfill disposal, or they can also be land applied for fertilization.

PLANT EXPANDABILITY/ PHASING A key in providing cost effective treatment designs is the ability to provide flexibility. Each Santec facility can be expanded to accommodate additional hydraulic flow, or modified influent concentrations simply by bringing additional reactors on line to maintain the appropriate treatment levels and detention times. Plants can also be upgraded to include such process designs as disinfection and denitrification by adding reactors to the original treatment design. Santec plants do not typically require concrete footings or tie-downs and are buried in pea-gravel. This makes expansions or upgrades inexpensive in terms of excavation, and simple in terms of accessibility. A common application utilizing the flexibility of the Santec design is the staging of plant size to coincide with development. Often, projects such as subdivisions are developed over a period of

time, or in phases. Santec plants are easily modified to reflect actual demand. This saves the owner a large portion of initial cost while affording him (and the regulatory agency) the opportunity to view the performance of the treatment process over time before committing to the final plant.

AESTHETICS Odor control, visual impact and noise mitigation are all primary concerns for developments investigating options for onsite treatment of wastewater. The sub-grade installation and nature of the Santec design lends itself to minimizing the impact it will have on the surrounding area. Odor control at our facilities begins with the fully contained fiberglass tanks installed underground. Gasses and odors produced by the treatment process are contained in the tank instead of being released directly into the atmosphere. The trapped gasses can then be directed to activated carbon filters which remove the particles from the air that are the source of odor. The underground fiberglass tanks also provide for a discrete visual profile. Tens of thousands of gallons of treatment capacity can be hidden under the ground. A simple 6 foot security wall or fence can completely obscure the facility from view save the top of the equipment building. Many facilities will use effluent to irrigate landscaping and trees around the facility providing for a discreet and more aesthetically pleasing site. Mitigating noise is accomplished through the minimal use of mechanical components. The mechanical portions of our facilities are enclosed in the equipment building and located inside of the underground tanks. Our facilities are quiet enough to locate in close proximity to homes and businesses with disturbing the neighbors.
