Case Study: Client recovers $5 Million in coal after coal pile runoff pond volume reduction

Client: Large American Power Company
LOCATION: United States
Flow: 50-1000 GPM
Processes: Actiflo® Turbo & Hydrex Chemicals


The Client had a need to treat and discharge coal pile runoff water containing high amounts of total suspended solids from its facility. 
The Client had tried several other technologies  in the past such as conventional clarification, DAF & compressible sponge-like media filters, developed by Veolia’s competition with no satisfying result. 


The Client contracted Veolia to rent an ACTIFLO® TURBO trailer (capable of 1200+ GPM) coupled with HYDREX™ chemicals. Veolia was also awarded an operations contract, offering the Client a hands-off approach.  Key to the overall success of the project, Hydrex™  chemicals supplied a blend of two coagulants and a flocculant/polymer needed with the microsand. 

Veolia treated over 50 million gallons of water in clarification mode;  at instantaneous flows of 500 – 1000 GPM. Additionally, the process allowed for the recovery of approximately $5,000,000 USD in coal from the basin/pond once the pond level was brought down. The site also was able to ensure that the effluent met the plant's required discharge quality.

Mobile Water Filtration and Treatment Applications


  • Using Actiflo Turbo technology to maximize capacity and minimize footprint and energy consumption

Where can mobile ultrafiltration (UF) water treatment be used?

Mobile ultrafiltration technology can be applied in a variety of applications including:

  • RO Pretreatment - eliminate media filtration (MMF) or even settling processes
  • As Final Treatment - eliminate any particulates and bacteria from treated water
  • In Place of Settling Equipment - for precipitation, low level clarification, etc. it can remove the precipitated solids instead of using a clarifier
  • Recycle Stream Treatment
  • Cooling Tower Blowdown Metals Removal

  • Single pass < 5% salt passage
  • Double pass < 2% salt passage

What is mobile reverse osmosis?

Mobile reverse osmosis (RO) refers to portable, self-contained reverse osmosis systems that are designed to be easily transported and deployed in various locations. These units are typically mounted on trailers, skids, or compact frames, making them mobile and suitable for temporary or remote water treatment applications.

A mobile reverse osmosis system typically consists of the following main components: 

Pretreatment system: This includes filters, such as sediment filters, carbon filters, and multimedia filters, to remove suspended solids, chlorine, and other contaminants from the feed water before it enters the RO membrane.

High-pressure pump: A high-pressure pump is used to force the feed water through the semi-permeable RO membrane at a sufficient pressure, typically between 200 and 1,000 psi (14 to 69 bar).

Reverse osmosis membrane: The heart of the system is the RO membrane, which is a semi-permeable membrane that allows water molecules to pass through while rejecting dissolved salts, minerals, and other contaminants.

Control and monitoring systems: Mobile RO units are equipped with control panels, instrumentation, and monitoring systems to regulate the operation, monitor performance, and ensure proper functioning.

Storage tanks: Treated water (permeate) and concentrated waste (reject or brine) are typically stored in separate tanks or bladders.

The modular and compact design of mobile reverse osmosis systems allows them to be easily transported by truck, trailer, or even aircraft, making them suitable for deployment in remote areas, disaster zones, or temporary sites where access to clean water is limited or unavailable. These systems can treat various water sources, including brackish water, seawater, surface water, and even some industrial wastewater streams, to produce high-quality purified water for drinking, industrial processes, or other applications.
