Revolutionizing Wastewater Treatment Efficiency in North Wales
In an innovative project based in North Wales, engineers have introduced advanced methodologies to enhance the efficiency of wastewater treatment, realizing substantial cost savings estimated at £3.5 million. Alison Miles from NIVUS, an instrumentation collaborator on this endeavor, elaborates on the state-of-the-art flow measurement technology that has played a pivotal role in these advancements.
Project Overview
The Five Fords Wastewater Treatment Works (WwTW), run by Dŵr Cymru Welsh Water, caters to over 130,000 residents near Wrexham in northeast Wales and employs three activated sludge process (ASP) lanes.
Mott MacDonald Bentley (MMB), serving as a Capital Delivery Partner and part of the Welsh Water Alliance, faced challenges increasing the treatment capacity of the ASP lanes due to rising population numbers and heightened demands from emerging anaerobic digestion facilities.
The Flow Management Challenge
Upon assessing the plant’s configuration, it became evident that each ASP lane was receiving wastewater at varying flow rates. This inconsistency was confirmed through dissolved oxygen readings indicating inefficiencies across lanes. “For instance,” notes Jack Jones from MMB, “one lane functioned under super-critical conditions while another remained sub-critical,” complicating effective management.
This uneven distribution stemmed from several physical constraints within the feed channels and exacerbated by an 800mm relief pipe discharging a blend of returned activated sludge (RAS) into the main inflow channel which further distorted flow profiles.
Originally equipped with flumes for managing flow rates, these were upgraded to weirs to boost capacity; however returning to flumes for additional enhancements would not resolve existing disparities nor be feasible given structural limitations.
Pursuing Effective Solutions
Aiming for increased precision without disrupting plant operations significantly ruled out options such as installing equal-weir split chambers due to anticipated costs and extensive civil works required during construction phases—potentially attracting extra expenses upwards of four months’ operational downtime necessitating temporary pumping solutions that did not prove viable financially.+
Hello Convenience: The Flow Monitoring Necessity
A crucial element also involved monitoring flows within the relief line—a process relegated through traditional methods like electromagnetic flow meters which demand full pipes for accuracy alongside high installation costs typically requiring prolonged downtimes. In contrast, recent trials illustrated that comparing NIVUS’s insertion probe against conventional ‘magflow meters’ showcased savings up to 60% financially while achieving a staggering reduction of embodied carbon emissions by nearly 95%, prompting exclusion of magflow approaches outright; hence steering focus toward alternative functionalities offered by NIVUS equipment instead.
The Chosen Approach: Actuated Penstocks Installation
An intensive evaluation involving hydraulic specialists culminated in deploying three actuated penstocks into designated channels—intentionally isolating one lane for potential future requirements—while successful control demanded accurate downstream measurements post-penstock installation challenged traditional measurement techniques previously eliminated based upon spatial restrictions along with prohibitive civil upgrades costs incurred via expected heavy excavation efforts.” As Josh Sparks asserts: “Our company embraces forward-thinking solutions yielding multifaceted benefits—and our effort achieved just this here at Five Fords.”
