Wastewater Parameter Monitoring and Control:
Does your plant measure up to new Ofwat requirements?

The ambitious Water Industry National Environment Programme (WINEP), encompasses thousands of outputs. The largest subset of these, wastewater outputs, regards chemical phosphorus removal. Water companies in England and Wales will be required to meet the directive demands of the AMP7 WINEP (2020 – 2025) as soon as December of 2021, with the majority of regulation, including the phosphorus programme, to be reached by December 2024.

 

Hach ® can help you achieve WINEP compliance certainty. 

For over 87 years water quality has been our focus. Hach is ready to aid you in meeting the customer demands for affordable and resilient service established during Ofwat’s Price Review 19 (PR19).

Our proven instruments, systems, and service for total phosphorus, alkalinity, total iron, aluminium and trace metals parameter monitoring add real-time-control (RTC) to ensure compliance.

Easy, affordable—and lots more you may not know about RTC-P

With more than 1500 installs across Europe since 2012, RTC modules offer a proven solution for wastewater monitoring and output control that is affordable, easy to install and easy to use across multiple sites.

AMP7 is the most ambitious wastewater monitoring cycle yet.

By the time the new Ofwat PR19 water 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 Parameter Monitoring

Phosphorus

 

Reduce capex and carbon emissions with Hach’s phosphorus real time control system. Historical plant performance need not reflect what is really achievable with existing assets and advanced control. More information.

Phosphorus - the most common cause of water quality failures in the UK. More than 50% of rivers and 75% of lakes currently exceed the set standard for phosphate levels.

Hach understands the challenges that water companies and their partners face within the AMP7 cycle. The costs of failing to meet WINEP compliance are far higher than the investment in continuous monitoring solutions. Consequences of insufficient chemical phosphorus removal can include steep fines levied by Ofwat and other environmental regulators, fish kills or algae blooms that impact community water sources, as well as negative impacts on the reputation of the water utility as a neighbor, 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 within the Water Framework Directive.

Solution: RTC-P provides compliance certainty in 5 simple steps

1. INVEST » 2. INSTALL » 3. COMMISSION » 4. OPTIMISE » 5. COMPLY

Since 2012 more than 1,500 standardised RTC-P control modules have been successfully installed on more than 800 sewage treatment plants 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 installs in continental Europe and the UK have proven that quick, decisive and consistent parameter control is possible at previously unheard-of levels.

 

With a turnkey solution and Hach support, even the most ambitious AMP7 compliance goals are within reach.

How it works: RTC-P is feed-back and feed-forward in one

Hach’s load-based RTC-P system gives you more insight into your operations by providing two chemical dose signals from a single phosphorus measurement point.

RTC-P 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 levels and enhancing your chemical phosphorus control system, RTC-P enables WINEP 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.

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

Because it is hosted by specific hardware, RTC-P software easily combines with other control modules.

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.

To protect the environment from excessive wastewater chemical application, Ofwat commonly allies phosphorus permits 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
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 in accordance with the Water Framework Directive.

Zinc, Copper, and Nickel

Based on the data collected during the chemical investigation programs (CIP1 and CIP2), the environment agency adjudicates for more than 120 new permits for chemical compounds on diverse wastewater treatment works. Drivers of these new chemical consents are linked to the current quality of the water where the treated wastewater is discharged and/or to former investigations made at the treatment works. The ultimate goal is to improve river water quality or prevent it from further deterioration. Among chemicals at stake, several dissolved metals are targeted such as zinc, copper, or nickel.

Hach samplers associated to our laboratory metal solutions can help you to increase catchment knowledge during AMP7 and to identify potential traders and industrials at risk on the sewage system. In addition to these investigations, a continuous monitoring of dissolved metal in the outlet of the wastewater treatment works may be of help to demonstrate nonstop compliance, understand possible load variations and check treatment efficiency where necessary.
