Phosphorus Removal from Water

Gel Flocculant for Nutrient Removal

Supporting phosphorus and nutrient reduction through particle capture

Algae Removal Morning Day 1

We provide water treatment and phosphorus removal solutions to reduce nutrient overloading and prevent algal blooms in construction and industrial runoff.

Nutrients such as phosphorus often attach to fine soil particles. When these particles enter watercourses, they drive algal blooms, oxygen depletion and ecological harm.

Clearflow’s Gel Flocculant accelerates the capture of fine sediments and their associated nutrients, providing a practical treatment step to support compliance with tightening discharge consents in sensitive catchments.

We welcome further opportunities for pilot programmes in partnership with government agencies and academia in the UK.

Applications range from:
  • Construction and catchment storm water treatment
  • Road run-off management
  • Water treatment
  • Mining

Key Benefits

Leading the way in nutrient pollution control

Particle bound nutrient removal

Gel Flocculant captures suspended particles that carry phosphorus and other nutrients

Regulator accepted

Gel Flocculant has been deployed on sensitive sites with strict discharge consents, where flocculation is an approved pathway for reducing particle bound phosphorus

Performance evidence

Reductions in phosphorus, COD and turbidity have been demonstrated in real-world case studies, including West Cumbria (UK) and Innisfil (Canada), supporting regulator acceptance.

Low cost, low carbon

Passive or pumped dosing avoids the high energy and chemical footprint of tank based treatments

Process-led approach

Our Settlement Testing part of the service confirms site chemistry, optimum formulation, dose and installation

Scalable technology

We support small construction discharges to road run-off and large scale mining or industrial applications

Technical specification

Form Dehydrated Gel Flocculant blocks, with formulations designed to target fine particulates for rapid settlement.
Mechanism Nutrients such as phosphorus are often particle bound. By flocculating and settling these particles, overall nutrient load is reduced.
Performance evidence Case studies demonstrate phosphorus reductions from 0.1 mg/l to 0.02 mg/l (West Cumbria, UK) and average phosphorus reductions of 90% in stormwater discharges (Innisfil, Canada), alongside reductions in TSS and COD.
Deployment options Passive flow systems for drains, channels and road run-off, or pumped deployment using GFR for higher flow or higher risk applications.
Whole life cost and carbon Lower footprint and operating cost compared with chemical dosing or settlement tanks, with carbon benefits from simple, passive operation.

Well presented webinar. Very thorough discussion of all aspects of silt management and good practice. I was knowledgeable but learnt much more about the latest good practices and what to consider in management – mainly drainage and run-off! Now time to up my game introduced new techniques and practices.

It’s good to see Frog getting involved with GT at the earliest stages of the project to help with planning out water management in advance of needing it.

What I enjoyed about the training was the practical techniques for sediment control with examples and case studies, the slides demonstrating how effective the correct intervention can be, and the costings which showed prevention is better than cure.

Feedback from our training session
Aire Rivers Trust

The training is necessary in an industry where it’s often overlooked. You get told too many times that “water is water!” If more of these sessions are run, there will slowly be a mindset shift in the right direction. By demonstrating the importance of surface water management on construction sites empowers us ECoW.
