The UK public, using rivers for activities ranging from sports and swimming to fishing, risks falling ill from bacteria in sewage and slurry. Chemicals, plastics and an excess of nutrients are choking the water, threatening our rich biodiversity of plant, fish and insect life.

The Challenge for Water Companies

Water utility companies are already under severe pressure from regulators to meet ever-tighter discharge consents, often with creaking infrastructure and old or overloaded wastewater treatment plants.

Throughout England and Wales, water companies have promised to invest £4bn by 2025 to reduce sewage leaks. The water industry, agriculture and commercial sectors urgently need better solutions and more effective environmental returns for their investment.

Biological Nutrient Removal is an effective wastewater treatment solution which removes phosphorus and nitrogen from wastewater before it is discharged to the water system, without any need for chemicals.

What Can Be Done?

Plantwork Systems’ products and processes demonstrate a powerful example of the kind of integrated solutions that are needed to reverse the unacceptable trend.

Biological Nutrient Removal (BNR) is an effective wastewater treatment solution which removes phosphorus and nitrogen from wastewater before it is discharged to the water system, without any need for chemicals.

Water engineers understand the importance of BNR but have found implementation to be too expensive and intrusive on space, with unacceptable downtime periods detrimental to the running of the plant.

We at Plantwork Systems have adapted these processes to retain and improve the environmental benefits, whilst reducing the cost and footprint.

Our technology – NUTREM® – brings the whole process into the 21st Century at a very competitive cost.

The Ideal Solution

With NUTREM®, water companies, commerce and developers get industry-leading nutrient removal in an environmentally sustainable way, at the same time as offering a number of cost benefits. NUTREM® has an innovative modular construction, requires a smaller footprint than other options, consumes less energy than more 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:

R

Industry-leading level of Total Phosphorus (TP) removal (below 0.25 mg/l)

R

Industry-leading level of Total Nitrogen (TN) removal (below 5 mg/l)

R

Ability to meet 0.1mg/l TP with the addition of tertiary filters

R

No dosing requirements

R

Effective in all seasons (i.e. including weak sewage strengths)

R

Lower capital expenditure

R

Lower operating costs

R

Smaller footprint, with resulting cost saving

R

Modular and scalable, allowing costs to be spread

R

High quality effluent capable of re-use without tertiary treatment

R

Virtually odour-free operation

R

No corrosive by-products
