Marsh Phos-Lite is designed to efficiently remove phosphate from wastewater. Utilising an adsorption process, it binds phosphorus to the surface of its media, which is composed of naturally occurring elements. This ensures long-term performance across varying flow rates and influent concentrations. Recommended for up to 35 Population Equivalent (PE), Phos-Lite is fully scalable to meet larger demands.

The plant is engineered for maximum retention time, guaranteeing stable, low effluent phosphorus concentrations certified by PIA GmbH at 0.2 mg/l. With an electrical consumption of just 0.03 kWh/d, Phos-Lite operates at very low cost.

This innovative tertiary treatment solution seamlessly connects to the outlet of both new and existing treatment plants. As well as removing phosphate it also significantly reduces other key effluent constituents:

COD reduction by 56.1%.
BOD reduction by 59.5%.
Suspended Solids reduction by 61.1%.
Total phosphate (Ptot) efficiency at 95.9%, achieving 0.2 mg/l.

Features and benefits:

Designed to retain up to 8.5 kg of phosphorus over five years for a 6PE domestic plant (British Water Flows and Loads 4), Phos-Lite offers reliable performance. After this period, media performance can be reassessed and replaced if necessary, representing approximately 50% of the tested capacity.
The plant uses Phos-Lite pellets, a natural mineral media, to reduce phosphate levels, simplifying operations and reducing the environmental impact of chemical use.
The non-dosing approach minimises the need for frequent maintenance and chemical adjustments, leading to cost savings over the plant’s lifetime.
The plant is designed for seamless integration into existing systems, making it versatile for new installations and retrofits.
By achieving phosphate levels of 0.2 mg/l, the plant ensures compliance with the tightest environmental standards, allowing water companies to meet regulatory obligations.
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.
