Water and Wastewater Treatment

Nature‑based, circular and carbon‑negative solutions for phosphate and nutrient removal across agriculture, industry and municipal water and wastewater systems.

Practical, sustainable technologies for removing excess nutrients like phosphate and recovering valuable resources across all major water sectors. Built on natural bioresources and circular design, our nuRe approach offers a reliable, low‑impact alternative to conventional nutrient removal.

The Challenge: Excess Nutrients in Water

Phosphate pollution affects every part of the water landscape:

Water companies face tightening discharge limits and rising compliance pressures.
Farms manage slurry, runoff and high‑nutrient wastewater that impact soil, ditches and downstream ecosystems.
Industrial sites generate nutrient‑rich process water that requires treatment before discharge or reuse.
Private operators of water treatments like holiday parks, campsites ace similar regulation tightening limits.

Traditional treatment methods can be costly, energy‑intensive, difficult to scale and prone to producing secondary waste.

Rookwood tackles these challenges with a simple, circular approach:
Recover nutrients where they cause harm → Reuse them where they provide value. Using

nuRe is Rookwood’s integrated approach to nutrient recovery. Combines natural materials, modular hardware and flexible service models to deliver efficient, sustainable phosphate removal across diverse water environments.

The launchpad for nuRe is PRM — Phosphate Recovery Material, our patented, carbon‑negative adsorbent engineered for targeted, high‑efficiency phosphate capture—from municipal wastewater to sensitive freshwater ecosystems and much more.

Engineered for Superior Nutrient Recovery

PRM and nuRe materials are made from natural, modified, carbon‑negative biomass designed to bind contaminents and nutrients effectively across municipal, agricultural and industrial water streams.

Key Advantages

High adsorption capacity extending lifespan and reducing changeouts.
Versatile across water types — effective in slurry, runoff, municipal effluent, surface water and process streams.
Carbon‑negative — production actively sequesters CO₂, supporting climate‑positive operations.
Environmentally safe — stable pellets that do not leach contaminants or break down in water.
Circular — saturated material can be repurposed as a phosphate-rich soil amendment (subject to regulatory approval).
