GLOBAL PILOTS
Pilot study for the College Water Treatment Works of South West Water UK
In 2016, a pilot study for the College Water Treatment Works was completed. ILCA® and CeraMac® were tested to treat an algae-laden reservoir source, and it was the first site were we tested a cleaning-in-place procedure for the membranes with ozone. The processes effectively treated this challenging source. Different coagulants…
Pilot study for Melbourne Water
During this pilot ozone combined with ceramic membranes to treat secondary effluent was evaluated at Eastern Treatment Plant (ETP), Melbourne. The overall objective of this project, funded primarily by the Australian Water Recycling Centre of Excellence, was to demonstrate the performance and cost benefits of ceramic membranes to treat water…
Pilot study Manitowoc Public Utilities, Wisconsin USA
In November 2014, PWNT, in partnership with METAWATER and MPU, started a one-year pilot study of ceramic membranes directly on the water from Lake Michigan. This unit includesdequipment for pre-coagulation and a ceramic micro filter with a single, full-scale 269 sqft (25 m2) membrane module. The key pilot results are:…
Micro-contaminant control study – Evides, Rotterdam
In the last quarter of 2014 Evides contracted PWN Technologies to give direction to their research challenge about micro-contaminant control. This AOP scenario study led to several scenarios of which the most promising will be piloted by Evides. Pre- and post treatment are being recognized as being key in investigating…
Pilot study at Invercannie for Scottish Water UK
In July 2016, a 12-month pilot study was initiated at the Invercannie Water Treatment Works in Scotland. This pilot included SIX®, ILCA®, and CeraMac®. The River Dee is typical for a lot of sources in Scotland, flashy and can contain significant high levels of color and suspended materials, which can…
Joint pilot study evaluation Norrvatten-Stockholm Sweden
This pilot study began in September 2016 at WTW Lövo of Stockholm Vatten, and investigated the use of SIX®, ozone, ILCA®, and CeraMac® membrane filtration for treating water from Lake Mälaren. This lake is the biggest in Europe and the main source for the drinking water utilities in the Stockholm…
Pilot study for Water Corporation Australia
A pilot study began in early 2017 treating secondary effluent for a reuse application with ozone, ILCA®, and CeraMac® membrane filtration. Ozone demand and membrane performance at different coagulation pH values was assessed, along with the finished water quality. The pilot is now relocated to a a drinking water testing…
Desalination pilot study Tuas PUB, Singapore
A pilot study as pre-treatment to desalination was conducted in 2016. This study investigated the possible operational settings for CeraMac® with coagulation pre-treatment. CeraMac® treatment appears to be an excellent treatment system for desalination purposes. Water quality was monitored for suitability as pretreatment to downstream reverse osmosis.
Sembcorp pilot study at Changi, Singapore
In the Fall/Winter of 2013/2014 a pilot study of ceramic membranes for treating secondary wastewater effluent was conducted at Changi Waste Water Treatment Plant facility. This study was used to support conceptual design efforts for a proposal for the expansion of the Changi NEWater facility of Singapore’s PUB. The pilot…
Pilot study at Turriff for Scottish Water UK
Scottish Water (SW) conducted a pilot-scale evaluation of in-line coagulation (ILCA®) and ceramic membrane filtration with a mobile pilot plant from February to May 2019 at the site of Turriff Water Treatment Works (WTW). The aim of this pilot study was to evaluate the performance of ILCA® and CeraMac® for…
Pilot study at Marchbank for Scottish Water UK
In the autumn of 2019, Scottish Water began a six-month pilot trial of ILCA® + CeraMac® on the Megget reservoir source, which is a low turbidity source water with moderate dissolved organic carbon. Testing was conducted with polyaluminum chloride at different pHs through the winter season. A thorough water quality…
Piloting for Hampton Loade WTW at South Staffs Water
In November 2019, a pilot study began for water from the Chelmarsh Reservoir at the Hampton Loade WTW. This reservoir is fed by the river Severn, but provides sufficient residence time to dampen swings in water quality. ILCA®+CeraMac® was considered for a plant upgrade, and pilot testing was used to…
Pilot testing for Seedy Mill WTW at South Staffs Water
In February 2020, water from a dissolved air flotation system was treated by ceramic membrane filtration in a pilot plant. Different fluxes were tested, along with the backwash interval and enhanced backwash interval.
Pilot testing for Bedok Water Works in Singapore
Planning is underway to begin pilot testing in mid-2020 to evaluate the CeraMac® with different pre-treatments.
Pilot testing at Anglian Water for SIX®
In the summer of 2019, a 12-month pilot-scale evaluation of the SIX® process was performed at the Hall WTW location of Anglian Water. Anglian Water wanted to understand how the SIX® process can improve organics removal for Hall WTW and its impact on disinfection by-product formation. The main process removing…
