Product Overview

The LINZHEN MBR/MBBR Wastewater Treatment System is an advanced, fully integrated water purification solution engineered for industrial wastewater treatment, municipal sewage processing, river water restoration, and water reuse applications. Combining Moving Bed Biofilm Reactor (MBBR) biological treatment with Membrane Bioreactor (MBR) ultrafiltration technology, the system delivers consistently high effluent quality while occupying a significantly smaller footprint than conventional treatment plants.

Designed and manufactured in Shandong, China, every LINZHEN system is built to order with customizable processing capacity, voltage configuration, and material selection — including carbon steel and stainless steel options — ensuring a precise fit for your project requirements. The equipment carries CE, ISO, SABER, and COC certifications, meeting international quality and safety standards for deployment across global markets.

Compared with traditional activated sludge processes or standalone biological treatment methods, the MBR/MBBR hybrid architecture offers superior removal rates for COD (Chemical Oxygen Demand), BOD (Biochemical Oxygen Demand), TSS (Total Suspended Solids), ammonia nitrogen, oils, grease, and phosphorus. The membrane separation stage produces clarified effluent suitable for direct environmental discharge or tertiary treatment for non-potable reuse, helping industries and municipalities reduce freshwater consumption and meet increasingly stringent regulatory standards.

How the MBR/MBBR System Works

The LINZHEN wastewater treatment system operates through four sequential stages, each optimized for maximum pollutant removal efficiency:

Stage 1 — Preliminary Treatment

Raw influent first passes through mechanical screening equipment that removes large particulates, plastics, fibers, grit, and other coarse debris. This protective stage prevents downstream equipment fouling and ensures stable operation of the biological and membrane units that follow.

Stage 2 — MBBR Biological Treatment

Screened wastewater enters the Moving Bed Biofilm Reactor, where thousands of specially engineered biofilm carriers provide high-surface-area attachment sites for microorganisms. Under controlled aeration, these microbial communities form dense biofilms that aggressively metabolize organic pollutants. The MBBR stage effectively reduces COD, BOD, ammonia nitrogen, and a broad spectrum of organic contaminants. The suspended carrier design provides inherent resistance to hydraulic and organic load fluctuations, making the system particularly robust for industrial applications with variable discharge characteristics.

Stage 3 — MBR Membrane Filtration

Mixed liquor from the MBBR stage flows into the Membrane Bioreactor unit. Here, submerged ultrafiltration or microfiltration membranes physically separate treated water from suspended solids, bacteria, and residual biomass. The membrane barrier achieves effluent turbidity levels below 1 NTU and consistently produces water quality that meets or exceeds discharge standards. Unlike conventional sedimentation, membrane filtration is independent of sludge settling characteristics, eliminating bulking issues and ensuring dependable performance.

Stage 4 — Disinfection and Final Polishing

Depending on end-use requirements, the permeate can be directed through UV disinfection, chlorination, or advanced oxidation processes. For water reuse applications — including landscape irrigation, cooling tower makeup, industrial process water, and environmental flow augmentation — additional polishing stages such as activated carbon filtration or reverse osmosis can be integrated.

Key Advantages

Exceptional Treatment Efficiency

The MBR/MBBR combination delivers removal rates exceeding 95% for COD and BOD, over 90% for ammonia nitrogen, and near-complete TSS elimination. This performance exceeds what either technology can achieve independently.

Compact, Space-Saving Footprint

By eliminating secondary clarifiers and operating at higher mixed liquor suspended solids (MLSS) concentrations, the system requires 30–50% less installation area than conventional activated sludge plants of equivalent capacity. This is critical for factories, urban installations, and retrofit projects where available space is limited.

Stable Effluent Quality Under Variable Loads

Industrial wastewater streams frequently experience flow rate surges and pollutant concentration spikes. The MBBR carrier biofilm provides a resilient biological buffer, while the physical barrier of the MBR membrane ensures effluent quality remains consistent regardless of upstream fluctuations.

Broad Industry Applicability

The system is customizable for diverse wastewater profiles across industries including food and beverage processing, pharmaceutical manufacturing, chemical production, textile dyeing and finishing, electronics fabrication, pulp and paper, and municipal sewage treatment. Process parameters — hydraulic retention time, sludge retention time, aeration intensity, and membrane flux — are tailored to each application.

Lower Long-Term Operating Costs

Automatic PLC control with real-time monitoring reduces manual operator intervention. Optimized aeration strategies, low-fouling membrane materials, and energy-efficient pump selection collectively drive down power consumption, chemical cleaning frequency, and maintenance labor costs over the equipment lifecycle.

Built-In Water Reuse Capability

The membrane permeate quality is inherently suitable for non-potable reuse. Integrating reuse into your treatment chain reduces freshwater intake costs, lowers wastewater discharge fees, and strengthens environmental compliance credentials — an increasingly important factor for ESG-conscious operations.

River Water Purification & Environmental Restoration

River pollution from organic matter, suspended solids, excess nutrients, and industrial point-source discharges is a pressing global environmental challenge. Conventional river treatment methods often struggle with highly variable inflow quality and the need for rapid, reliable contaminant removal.

The LINZHEN MBR/MBBR system addresses these challenges through its dual-action approach: biological degradation of dissolved organics combined with physical membrane separation of particulates and microorganisms. Deployed as a river water purification station, the system improves water transparency, reduces suspended solids, controls nutrient levels that drive eutrophication, and stabilizes overall water quality. The modular, containerized design enables phased deployment and scalability for ecological restoration programs, urban waterfront improvement projects, and water reuse initiatives.
