The EPA recently rolled out the final, updated ELGs for the power generation industry. ProChem and EES have partnered to provide a solution that not only meets these limits but exceeds them. The KLeeNwater solution features ProChem’s I-PRO™ technology and a recommended chemical pretreatment program. Here is the data.

Analyte Unit Daily Maximum Limitation 30 Day Average Limitation KLeeNwater Process
Arsenic μg/l 11 8 <0.1
Mercury μg/l 0.788 0.356 <0.05
Nitrate/Nitrite mg/l 17 4.4 <0.1
Selenium μg/l 20 12 <0.1
Total Suspended Solids mg/l 100 30 0
Boron mg/l No current limit No current limit 0.5
Bromides mg/l No current limit No current limit <0.1
Chlories mg/l No current limit No current limit 7
Total Dissolved Solids mg/l No current limit No current limit 10
Sulfates mg/l No current limit No current limit 2

KLeeNwater can be integrated with existing wastewater treatment equipment and has a footprint that is a fraction of the size of traditional selenium removal systems. ELG compliance is possible with the KLeeNwater solution.

Advantages & Solutions

  • Eliminate load cycling issues associated with traditional biological systems
  • Capital costs 10% of traditional biological systems
  • Reuse 95+% of the water available instead of treating and discharging
  • Operating costs similar to biological and significantly cheaper than other reuse systems
  • Meet today’s regulations (Selenium and Nitrate/Nitrite) as well as potential future regulations
  • No additional capital or operational costs to meet potential future permits
  • Industry proven technology
  • Modular design provides simple installation with small system footprint

ProChem recently assembled and delivered an Ion-Exchange Pilot System for a new customer. This pilot system will remove nitrates from the customer’s wastewater. This system will be placed at the customer’s site for several weeks to demonstrate how the full scale process will work.

Pilot System Features

  • Skid-mounted and accessible by fork lift or pallet jack
  • Four 14.7″ x 40″ FRP vessels with poly liners
  • 2.5cuft ion-exchange media
  • Distributor system
  • Plumbed using 80PVC and 1″ high purity water braided tubing
  • Polypropylene pre-filter housing (20″)
  • 1/2 HP, 120V booster pump
  • Brine tank for on-site regeneration of ion-exchange media
  • Feed tank and effluent tank (275 gallons each)

ProChem is not the only industrial wastewater treatment company who is tweeting, posting, writing, and speaking about drought in the United States. Companies who provide products and services that support the treatment and handling of water for industrial facilities hear a call to action during drought.

You may be wondering why that is, under the assumption that big industry has plenty of water to make goods for people; that drought only impacts families who don’t have water to drink or for recreation, right? After all, these state-wide conservation mandates seem to be focused on individual communities and homes. It's true that industrial facilities use a very large amount of water: thousands of gallons per day in order to produce the goods that citizens purchase and consume. When there is a serious drought, as in California and much of the west coast, favoritism is not granted to these corporations. Water conservation quotas apply across the board to industry (high volume users) and households (low volume users). When the average home has trouble getting the volume of water they’re used to for watering their lawns, cooking, and drinking, you can bet that industrial facilities have more difficulty getting the volume of water they need to make products that keep their doors open—and their workers employed. Water is not only essential for life, it’s essential for the economy.

ProChem Industrial Wastewater Reuse Equipment and Services

Wastewater treatment professionals are innovators who develop technology that is meant to lessen a facility’s impact to the environment. In ProChem’s case, it is their water reuse system with I-PRO™, which was developed with conservation and sustainability as the driving force. I-PRO™ allows industrial facilities to recycle their wastewater at a rate of over 90%. Some of ProChem’s customers are achieving 97%+ with their water reuse system. This means that these facilities are consuming a fraction of the water they would without the I-PRO™ system. The less water they consume, the more money they save, which allows them to continue operating and providing their goods, services, and employment to the community. More importantly, during a drought, it means that the water they are not using remains available to the community for use. Industrial wastewater treatment companies like ProChem exist because they care about water quality and sustainability. It’s their business but also their calling. The “water problem” isn’t a new one, but severe drought brings this problem to each of our doorsteps, reminding us that we have to take action. Hundreds of companies are utilizing water reuse systems and taking other water conservation steps. ProChem is proud to provide the wastewater treatment chemistry, equipment, and professional operations services that help industrial facilities contribute to a drought solution in their community.
