QUEBEC CITY, CANADA, Feb. 5, 2015 -- H2O Innovation Inc., a specialist in membrane filtration, recently announced that it has completed the commissioning of one of its largest drinking water projects to date, designed for the city of Delaware, Ohio, to provide continuous support for the city with its proprietary remote monitoring solution SPMCTM (System Performance Monitoring Center).
The water treatment system, designed by H2O in collaboration with AECOM Technology Corporation (Columbus, Ohio) for Delaware, produces 7 million gallons per day (MGD) (26,498 m3/d) of drinking water. The system is comprised of three ultrafiltration (UF) trains and five nanofiltration (NF) trains treating water from two different raw water supply sources.
In order to provide its customers with sufficient potable water, Delaware pumps water from the Olentangy River and groundwater wells. To treat the river water, an existing flocculation and sedimentation system provides pretreatment to three new UF trains followed by three new NF trains. The net capacity of the surface water treatment system is 4.5 MGD (17,034 m3/d).
The groundwater source, which contains iron, manganese and hardness, requires a different treatment process that consists of greensand filtration followed by two new NF trains. The groundwater treatment system has a capacity of 2.5 MGD (9,464 m3/d). The treated surface water and groundwater streams are ultimately blended prior to pumping to the distribution system. By providing engineered process design for each raw water source, membrane fouling is minimized while optimizing operation and maintenance costs.
H2O continues to support Delaware by providing monitoring and performance analysis in real-time. Through SPMC, developed in-house, the company's process engineers and service team are capable of assisting the operators in their daily tasks as they learn the logistics of the new UF-NF treatment system. SPMC also enables operators to have remote access to the HMI to receive alarm notifications on their smart phones but more importantly, to get process recommendations such as the scheduling of the next membrane cleaning.
While clients are free to use the chemicals of their choice to maintain their system, H2O always proposes its complete line of speciality chemicals branded under the name Professional Water TechnologiesTM (PWT). After a careful evaluation, the city has decided to procure PWT's specialty chemicals for membrane scale inhibition and cleaning using the company's green chemistry -- a phosphate-free antiscalant.
