Proven Phosphorus Control for WINEP Compliance


AMP7 is the most ambitious cycle yet.

By the time the new standards take effect, municipal wastewater companies will be responsible for maintaining phosphorus consents as low as 0.1 mg/L while keeping rates as affordable as possible.

Spotlight on WINEP Phosphorus Standards

Hach fully understands the challenges that water companies and their partners face within the AMP7 cycle. When phosphorus is discharged in wastewater, usually in the form of PO 4, it “fertilises” algae and aquatic plants so they multiply and deplete the oxygen in streams, rivers and bays, ultimately choking out larger organisms and disrupting the healthy balance of the ecosystem.

We all know that Phosphorus is the most common cause of water quality failures in the UK, and more than 50% of rivers and 75% of lakes currently exceed the set standard. Regulations exist to protect water, wildlife and people from uncontrolled amounts of phosphorus in wastewater, and these regulations have an economic impact on your municipal and industrial treatment facilities. Although further investment is needed there are costs involved in removing phosphorus from wastewater, the costs of failing to remove it adequately or reliably are far greater and include steep fines levied by environmental regulators, fish kills or algae blooms that impact community water sources, and negative impacts on the reputation of the water utility as a neighbour, employer and brand.

Hach can help you in realising a return for your investment by robustly controlling eutrophication and limiting your phosphorus discharge to safe and compliant levels

Next Generation Phosphorus Removal

Hach’s RTC-P is a load-based system that optimizes chemical phosphorus removal by adjusting chemical dosing in real time through the continuous measurement of phosphate concentration and flow. By maintaining consistent effluent phosphorus values and enhancing your chemical phosphorus control system, RTC-P enables compliance certainty around the clock.

Once the system is programmed with a PO 4-P setpoint, it continuously measures PO 4-P concentration and wastewater flow rate, calculating the minimum amount of precipitant required to match the biological phosphorus uptake. The system will automatically switch to fallback strategies if input signals inflow or PO 4-P are not available.

 

Feed-back and feed-forward in one

RTC-P gives you more insight into your operations by providing two chemical dose signals from a single phosphorus measurement point.

Advantages include:
• maintaining minimum phosphorus level for biological requirement
• providing auto polish for a secondary dose point
• balancing phosphorus removal across the plant for chemical efficiency

Seeing is believing: RTC-P in action

Since 2012 more than 1,500 standardised control modules have been successfully installed on more than 800 sewage treatment plants across Europe with a load of just a few 1,000 PE up to 6 million PE.

With the correct combination of controllers, analysers, and communication capabilities, standard RTC-P installs in continental Europe and the UK have proven that quick, decisive and consistent phosphorus control is possible at previously unheard-of levels.

 

CASE STUDY: Phosphorus outlet reduced 45% (to 0.23 mg/L) in German WWTP with annual volume of 2.3M m 3

The results were immediate and dramatic with the installation of the water intelligence system, with reductions in all parameters measured in the outflow, and in energy consumption in bio tank blowers.

“The module has now been operating at our plant for almost three years without any problems. Using the latest software, it now works even better than before and fully meets my expectations.”

Phosphax sc Analysers from Hach provide accurate low range, medium range and high range orthophosphate measurement

Orthophosphate

Orthophosphate is also called “phosphate” or “reactive phosphorus” because its three “extra” electrons bond easily with other positive elements leading to problems like build-up and lower efficiency over time. The Phosphax analyser range provides accuracy at low, medium and high.

EZ Series Phosphorus Analysers from Hach provide low range phosphorus measurement

Total Phosphorus

Discharge of phosphorus encourages the growth of algae and aquatic plants that rob streams, rivers and bays of oxygen, thereby disrupting the ecosystem. Get accurate, continuous phosphorus monitoring at values as low as 0.01 mg/L, with optional nitrogen or phosphate measurement capabilities.

EZ Series Iron and Aluminum Analysers from Hach help control costs and effectively manage sludge

Total Iron and Aluminium

To protect the environment from excessive wastewater chemical application, phosphorus permits are commonly allied to iron and aluminium limits. These metal limits can represent even greater challenges than the phosphorus limit itself. To manage all risk associated with phosphorus permits we have a range of metal analysers to provide accurate, continuous monitoring for up to 8 streams.

EZ Series Alkalinity Analysers from Hach help control costs and effectively manage sludge

Alkalinity

Dosing of highly acidic ferric sulphate for phosphorus removal can place high demand on sewage alkalinity, dropping pH and inhibiting ammonium treatment. Composite samples often mask the true risk associated with chemical dosing, where peak application rates typically coincide with maximum ammonium concentrations. Continuous alkalinity measurements show true process risk and used in conjunction with Hach RTC strategies protect your biology.

Why RTC?

Hach’s RTC (Real Time Control) solutions are affordable, easy to install, off-the-shelf systems that improve treatment processes in real time, keeping your facilities compliant while reducing treatment costs.

Compliance certainty

The combination of process measurement technology and RTC modules is suited to react immediately to load peaks in the inlet to the sewage treatment plant in order to guarantee a consistent effluent quality. This ensures that legal requirements are met at all times.

Minimal capital investment

Although exact costs will depend on site requirements and existing infrastructure, a standard RTC-P install can bring your phosphorus within range for less than you may think.

A standardized system

The RTC modules can be quickly integrated into an existing automation structure without much effort. Standardized control algorithms eliminate cost-intensive on-site software testing during PLC installation, and Hach support during parameterization ensures that the transition to real-time-controlled wastewater management is seamless and safe.

Seamless coordination

Hach supports planners and system integrators through project management, providing everything from tender documentation and guides for installation and commissioning, to application-specific consulting and customised training sessions.

Visibility into multiple sites

RTC enables live performance monitoring so that unmanned and remote sites benefit from the same level of attention and precision control as one would expect at a major plant.

Ease of use

From intuitive user interfaces and high-visibility alerts, to units designed to need simple, infrequent maintenance, our priority is to ensure that your focus is on delivering service, not attending to software and hardware issues.

Ongoing support

A complete Service package includes local field service experts to provide routine maintenance visits and warranty repair, plus a team of remote technical experts with the ability to monitor your system to ensure optimum performance. It’s like having a Hach Technician right there with you at the facility.
