PRESERVE OUR WATER RESOURCES FOR
Clean Water Environmental has state of the art wastewater treatment, disposal, and recycling facilities for hazardous and non-hazardous wastewaters in two strategically situated Ohio locations to meet all your wastewater treatment needs.
We treat diverse streams of wastewater that come to us from chemical plants, refineries, landfills, and manufacturing facilities. Some examples of wastewater we can service are:
- Machine coolants and process waters
- Combustible and flammable waters (hazardous or exempt)
- Caustics and Acids
- Heavy metals laden waters
- Waters containing alcohols, glycols, oils, fuels, resins, and other organics
Clean Water Environmental uses both tried-and-true processes and technological cutting-edge systems to treat your wastewaters. Our goal is to meet regulatory compliance but also deliver environmentally friendly wastewater treatment services for our customers.
Pioneering the way into thermal wastewater treatment, our Mansfield facility operates the two thin-film evaporators which separate non-hazardous oily water from dissolved impurities by means of water evaporation into steam – which then shares heat energy back into the system prior to condensation and discharge.
Our continuously operating Dissolved Air Floatation (DAF) unit and chemical batch treatment tanks in Dayton offer the efficiency and flexibility not seen in any other Central Water Treatment (CWT) facility in our region.
Our unique Dayton thermal system combines state-of-the-art Evaporator technology with a pre-treatment Distillation column to lead the way in ultra-efficient wastewater treatment.
Initially, water moves into the evaporator unit, where it’s heated to its boiling point (212 deg F) in the body of the evaporator. It then flashes off and becomes steam.
What’s left behind is the concentration of high boiling point compounds (like solids, heavy metals, and other long-chain heavy organic molecules). The water, now steam, is recycled back into the system and shares its heat energy with the incoming waste, keeping as much heat in the system as possible. Finally, this new organics treatment unit uses a distillation column to remove the light-ends from the steam as it is recondensed (generally solvents like alcohols, ketones, and other quick evaporating hydrocarbons).
Because of the machine’s steam recompression, it is very energy efficient. The two residuals (the lights and heavies) are combined to be sent to a cement kiln as an alternate fuel. Soon we’ll be able to send the light ends back to clients who want them returned as a usable products. The recondensed water flows to our new bio plant for polishing prior to discharge into our municipal sewer system.
Our newest expansion in Dayton addresses the dissolved organics in wastewater through our Biological Treatment System twin reactor tanks. Biological coated membranes also allow us to service wastewater with higher ammonia or organic levels — typically defined as waters with Biological Oxygen Demand (BOD) and Chemical Oxygen Demand (COD) — before they are discharged. This smart system also recognizes a continuously “trainable” amount of other, specific organic compounds, which can be handled to complete the wastewater treatment process.
Because of the scale of our operation in Dayton, all the treatment systems are covered by a negative air pressure Regenerative Thermal Oxidizer (RTO). Our expansive RTO captures all process emissions, heats the pollutants and compounds to 1560°F+, and transforms them into benign CO2 (carbon dioxide) and water vapor. The RTO sets us solidly in place for our continued efforts towards Title 5 permitting. Title 5 permits are a component of the Clean Air Act, which governs the control of air pollutants.
