microBLOX™ Membrane Bioreactor (MBR) systems are fully functional solutions to wastewater treatment problems and are ideally suited for a wide range of applications, including, but not limited to: housing developments, state parks, rest areas, isolated communities, military camps, shopping malls, golf courses, resorts, casinos, sewer mining (scalping), some industrial and more. microBLOX technology was designed and engineered to be extremely simple to operate and optimize. This single stage process uses one set of blowers to provide mixing, air scouring and process oxygen. For higher strength waste, concentrated oxygen can be efficiently added to the process on an as needed basis. Each system can be guaranteed to meet the most stringent nutrient limits and online monitoring is available for ammonia, nitrates and phosphorus in the effluent. Backed by one of the largest water companies in the world, Ovivo, microBLOX systems are built on the experience of the Enviroquip® MBR system with our over 130 operating plants in the US and 330 plants worldwide.
A microBLOX system can be configured to run in flow-through or batch modes depending on site conditions and treatment goals. As shown below, influent (raw wastewater) is screened before filling a dedicated Equalization Zone. Equalized wastewater is then pumped into a single-stage MBR process designed to operate over a range of dissolved oxygen conditions to achieve nutrient removal targets. For smaller, municipal applications, process oxygen is delivered exclusively by membrane aeration. Biologically treated wastewater is then gravity filtered (or pumped) using KUBOTA® membranes to produce reuse quality effluent with only one tank; there is no recycle, no mechanical mixing and no fine bubble diffusers.
For higher strength wastes (e.g. light industrial or commercial), or to increase hydraulic throughput, options are available using various oxygen concentrator technologies. Oxygen makeup and delivery systems are completely skid mounted and easy to setup requiring only a few field connections. The onboard controls system is equipped with programming necessary for seamless integration.
Unlike other MBR systems, a microBLOX™ system integrates solids thickening into the biological process to keep waste solids handling costs down and to improve overall reliability. As necessary, partially digested, thickened solids are wasted to an integral Waste Activated Sludge (WAS) Storage Zone. WAS can be stored at 2% - 3% solids, which can reduce hauling frequencies by more than 5 times that of conventional (package) technologies using sedimentation for solid/liquid separation.
