Natural solutions for advanced sewage treatment, phosphate and nitrate removal

Marsh Industries proudly presents the Marsh Nutra-Lite, an advanced Sequential Batch Reactor (SBR) sewage treatment plant designed to enhance effluent quality for off-mains wastewater systems and significantly reduce biological nitrates.

The Nutra-Lite is available in capacities catering to sites for up to 50 people. With state-of-the-art technology and rigorously tested, the Nutra-Lite sets a new standard for sustainable domestic sewage treatment.

SBR technology provides superior effluent discharge

The Nutra-Lite sewage treatment plant harnesses SBR technology, achieving an impressive 84% biological reduction in nitrates. Unlike traditional methods, no chemicals or carbon are used – just biological processes.

The Nutra-Lite boasts the highest overall discharge quality of any plant available today. Additionally, a unique self-cleaning, self-sealing sediment reduction valve ensures total control over suspended solids. No mechanical parts provide reliability and efficiency.

Nutra-Lite not only excels in phosphate and nitrate removal but also significantly reduces other key effluent constituents: 

• COD: 95.8% – 33mg/l
• BOD: 98.7% – 4 mg/l
• TNb: 83.9% – 11.1mg/l
• NH4n: 99.1% – 0.5mg/l
• Ptot: 34.3% – 6mg/l
• SS: 97.1% – 11mg/l

Features and Benefits:

SBR technology for superior nitrate reduction - The Nutra-Lite harnesses SBR technology, achieving an impressive 84% biological reduction in nitrates. Unlike traditional methods, no chemicals or carbon are used – just biological processes.

Remote configuration and adaptability - Unique to Marsh Industries, the Nutra-Lite sewage treatment plant can be adapted to seasonal changes in biological treatment, ensuring optimal year-round performance. Remote configuration allows adjustments based on ongoing nitrate reduction research.

Secure telemetry and alarm monitoring - All Nutra-Lite sewage treatment plants feature bi-directional communication for maintenance and monitoring. Telemetry options include mobile connectivity or homeowner Wi-Fi/internet.

Efficiency and cost savings - A single compressor minimises electrical power consumption without compromising performance. Economy mode further reduces running costs during process changeovers.

Material strength and fire safety - Marsh Industries’ GRP material successfully meets the requirements of EN ISO 11925-2:2010 standards and is tested for direct flame impingement. All units come with a 25-year structural guarantee.

Certified performance - Rigorously tested at the world-leading notified test centre, PIA GmbH, in Aachen, Germany, the Nutra-Lite is certified to BS EN 12566-3, demonstrating its reliability and effectiveness.
