Ground-Breaking Technology – Plantwork Systems’ NUTREM® features in The Water Industry Journal
This month, the Water Industry Journal takes a look at Plantwork Systems’ industry-leading NUTREM® technology for Phosphorus and Nitrogen Removal, and our ground-breaking research and development for the future of wastewater treatment. Here we reproduce the content of their article published in the September 2023 issue.
NUTREM®Plant at Petersfield, Hampshire, UK
With Net Zero pressures intensifying and discharge targets coming under further scrutiny, we are all looking for ways to clean up. Biological Nutrient Removal (BNR) is clearly the answer, but many of the water companies have found implementation to be overly expensive and intrusive on space, with unacceptable downtime periods detrimental to the running of the plant.
NUTREM® – brings the whole process into the 21st Century at a very competitive cost.
With NUTREM®, water companies, commerce and developers get industry-leading nutrient removal in an environmentally sustainable way, at the same time as securing a number of cost benefits.
NUTREM® has an innovative modular construction, requires a smaller footprint than other options, consumes less energy than traditional BNR systems, with lower capital expenditure and lower operating costs.
All this makes NUTREM® ideal for new waste and sewerage developments, expansion of existing plants, new housing schemes, garden villages and a range of larger developments.
The key advantages of the NUTREM® process over alternative solutions are:
Industry-leading level of Total Phosphorus (TP) removal (below 0.25 mg/l)
Industry-leading level of Total Nitrogen (TN) removal (below 5 mg/l)
Ability to meet 0.1mg/l TP with the addition of tertiary filters
No dosing requirements
Effective in all seasons (i.e. including weak sewage strengths)
Lower capital expenditure
Lower operating costs
Smaller footprint, with resulting cost saving
Modular and scalable, allowing costs to be spread
High quality effluent capable of re-use without tertiary treatment
Virtually odour-free operation
No corrosive by-products
Matthew Irwin – PhD student at Southampton University
Combined research and development has led to some outstanding industry-leading nutrient removal results to levels below 0.1 mg/l total phosphorus.
Research & Development sponsored by
Severn Trent Connect – Petersfield – Southern Water Plant
Plantwork Systems has spent 10 years on R&D in this field to offer NUTREM® – an adapted BNR process which retains and improves the environmental benefts, whilst reducing the cost and footprint.
Also, Microbiologist Matthew Irwin is being sponsored by Plantwork Systems, currently undertaking an interdisciplinary PhD at the University of Southampton, focusing predominantly on Microbiology, and to a lesser extent Civil Engineering. This PhD is co-funded by Plantwork Systems and the South Coast Biosciences Doctoral Training Partnership (SoCoBio DTP). Within the University, he is completing the PhD under the supervision of Professor Jeremy Webb and Dr Yongqiang Liu.
Matt has already completed an MRes at the University of Southampton, investigating the effects of water hardness on the microbial composition and characteristics of bioflms within Aerobic Granular Sludge (AGS). Throughout his masters, Matt gained many skills in microbial analysis and a much greater understanding of sustainable wastewater treatment technologies.
For this PhD, he is particularly interested in the possibility of tailoring the microbial community within wastewater treatment reactors to enhance nutrient removal and reduce environmental impact.
All this combined research and development has led to some outstanding INDUSTRY-LEADING nutrient removal results to levels below 0.1 mg/l total phosphorus. When there is total confidence in consistent figures, Plantwork Systems will make a formal announcement to the water companies – which will change the expectations for phosphorus and nitrate levels for the entire industry.
Plantwork Systems also offers BNR Conversion of Activated Sludge Plants (CONVOX) where existing infrastructure needs updating rather that the whole new NUTREM® process being installed. This is a very attractive alternative to chemical dosing – eliminating associated risks and ongoing costs.
BNR Conversion of Activated Sludge Plants provide enhanced nutrient removal in existing infrastructure, with:
- No chemical handling, deliveries, or supply chain risk
- Reduced whole life cost and carbon footprint
- Lower sludge production
- Alkalinity improved through BNR stages
- Opportunity for phosphorus recovery
Plantwork Systems – Water Industry Awards Finalist
Plantwork Systems was recently nominated as a finalist in the Water Industry Awards for its work with South West Water in the rural villages around southwest England, many of which have small populations and operationally challenging wastewater treatment systems.
Due to the high cost of replacing these systems, and the fact that many of them are also situated in conservation areas, the water companies need fast, low cost, environmentally-friendly solutions which can be trusted to address suspended solids compliance issues and provide a reliable and financially viable solution. Plantwork Systems is installing our Filtration+ product to tackle these problems.
