Surge MBR at Healthcare Facility Kerala: Case Study

Introduction

Water quality and hygiene are of paramount importance in the healthcare sector, where wastewater contains a complex mix of organic matter, suspended solids, pathogens, and chemical residues. Effective treatment of sewage effluent is essential to protect public health, comply with environmental regulations, and support sustainable water reuse within healthcare facilities.

At a healthcare facility located in Konni, Kerala, the need for a dependable and high-performance sewage treatment solution was critical. To meet stringent treatment requirements and ensure long-term operational stability, the facility partnered with Theway Membranes to deploy Surge MBR Membranes. This case study highlights the successful application and consistent performance of Surge MBR technology in healthcare wastewater treatment.

The Challenge

Healthcare wastewater presents unique treatment challenges due to fluctuating loads and strict discharge quality requirements. The facility at Konni faced the following key issues:

• Moderate to High Turbidity & Suspended Solids: Influent sewage exhibited turbidity levels up to 50 NTU with TSS ranging between 150–200 ppm, increasing the risk of membrane fouling.

• Elevated COD & BOD: Organic matter from healthcare operations imposed a significant biological treatment load.

• Operational Reliability: Continuous operation without frequent membrane replacement was essential to ensure uninterrupted healthcare services.

• Maintenance & Cost Control: Fouling-related maintenance and cleaning cycles needed to be minimized.

• Regulatory Compliance: Treated water had to consistently meet stringent discharge and reuse norms applicable to healthcare facilities.

The facility required a compact, robust, and reliable MBR system capable of delivering consistent permeate quality under varying influent conditions.

The Solution: Surge MBR Membranes

After technical evaluation, the healthcare facility selected Surge MBR Membranes from Theway Membranes, designed to deliver superior performance in sewage and institutional wastewater applications.

Key Features of Surge MBR Membranes

• Advanced MBR Technology: Efficient removal of suspended solids, organic matter, COD, and BOD.

• High Fouling Resistance: Maintains stable operation even with variable influent quality.

• Consistent Permeate Quality: Produces high-clarity treated water suitable for reuse or safe discharge.

• Compact & Durable Design: Ideal for space-constrained healthcare facilities.

• Low Operating Costs: Reduced cleaning frequency and long membrane life ensure economical operation.
