MPW’s ultrafiltration/ reverse osmosis system solves ash pond issue

March 10, 2020

 View Full Case Study Thorough investigation, application of specialized equipment key to selenium removal. Problem A former coal-fired power plant in the Northeastern U.S. had converted to a natural gas source. However, due to stringent EPA mandates, its remaining coal ash ponds, the byproduct of decades of burning coal, would need to be mitigated. That […]

iWWD: Emergency Response Reverse Osmosis & Deionization Trailers

November 25, 2019

When a Louisiana chemical plant suffered a site-wide blackout, plant personnel learned they would have to bring each power-generation unit, and its corresponding water filtration system, back on-line individually. Facility workers quickly returned the onsite demineralization system to functional status, but it was receiving almost zero condensate return. To re-establish condensate return, which is a […]

Filtration units deployed for same-day purification

April 24, 2019

 View Full Case Study Problem A Kansas manufacturing plant was forced to shut down after unusually high sodium levels in the Kansas River led to increased salinity in city water. Conductivity of the city water also increased from 500 µS/cm to 1,600 µS/cm. This heightened water conductivity was problematic during the rinsing process as it […]

Customized RO improves long-term safety, efficiency

October 11, 2018

 View Full Case Study Problem An outdated deionization (DI) system in the paint-booth area of an Ohio automotive plant was failing to produce an acceptable quality of water and necessitated excessive chemical costs to meet approved throughput levels. Additionally, chemical leakage was causing damage to floors, valves and pumps near the system. Conductivity of influent […]

MPW’s CO2 removal system reduces costs for plant

June 20, 2018

 View Full Case Study Problem Before the commissioning of a Mid-western natural gas and steam-driven power plant, tests on the plant’s source water revealed elevated levels of carbon dioxide (CO2). With no plans for an on-site water-treatment facility, the plant relied on MPW as its exclusive deionization (DI) supplier. The facility is also a zero-liquid-discharge […]

Power plant utilizes clarifier to reduce pond dredging

May 22, 2018

 View Full Case Study  Problem Settling ponds are typically used in the wastewater treatment process, al-lowing for the natural removal of solids and turbidity from wastewater. Water is processed through the ponds so solid contaminants can settle and clean, re-usable water can flow over top. Though this technique is quite common in many industries, settling […]

MPW praised for coal ash pond closure

May 7, 2018

 View Full Case Study  Problem A Virginia power plant, which began generating electricity in 1958 with three coal-fired units, had decommissioned one of its units and converted the other two to natural gas. Despite no longer burning coal, two coal ash ponds remained, ne-cessitating a remediation project. In addition to the EPA’s National Pollutant Discharge […]

iWWD: Pulp and paper mill adopts mobile media filtration

November 7, 2017

View Full Case Study It did not take a structural engineer to realize the Pennsylvania pulp and paper’s clarifier required repairs. When the technicians from MPW Industrial Services arrived at the mill, steel I-beams were propped gainst the crumbling cement sides of the 1950s-era water purification system. Next to wood, water is one of the most […]
