Complete Wastewater Treatment Packages
Earthtek provides primary treatment equipment such as influent screens, primary treatment tanks, sludge removal, and aerobic digestion. Tertiary treatment systems include mechanical filtration systems, pressure sand filters, vertical cloth filters, and membrane filtration. Disinfection systems include liquid chlorine and UV disinfection. Other equipment typically provided includes PLC control systems with remote monitoring capability, flow meters, post aeration, and composite samplers.
The Sabre SBR is typically provided in buried or above-ground fiberglass tanks with treatment capacity up to about 200,000 gpd. It is usually preceded by primary treatment and storage that allows single-tank SBR operation with no inflow during the settling process. Larger package systems can also be provided in aboveground steel tanks. All of the Sabre SBR’s utilize separate mixing and aeration to provide denitrification for alkalinity recovery and filamentous control for better settling.
We use primary treatment tanks prior to the Sabre SBR for several reasons. The primary tanks settle the solids, float the FOG, and remove grit and stringy materials. This reduces the organic loading on the SBR which reduces the required tank size and power usage. The primary tank acts provides storage volume for influent during the SBR React, Settle and Decant phases. The excess waste activated sludge from the SBR is also sent back to this tank for free anaerobic digestion. This tank is typically pumped every 1-3 years.
The Amber MBBR treatment plants are attached-growth biological treatment processes that use special carriers suspended in the wastewater in order to create a large surface area for biofilm growth. The MBBR plants can be designed as a stand-alone treatment processes or can proceed or follow other processes to provide pre-treatment, effluent polishing, nitrification, or nutrient reduction. The MBBR process is also typically used for industrial wastewater treatment.
With an Earthtek septic tank effluent pump (STEP) collection system, raw sewage flows from the house or business to an underground, watertight fiberglass tank for primary treatment. Only the filtered liquid is discharged by a small pump through shallow, smalldiameter collection lines that follow the contour of the ground. Solids remain in the tank for anaerobic digestion and are typically pumped only once every 10-12 years. The tanks are watertight, lightweight, and cost effective compared to grinder pump collection systems.
