Case Studies

Bakery
EnviroAqua was presented with an opportunity to help a California bakery solve a water treatment problem after their city government issued an ultimatum: treat the waste or the plant would be shut down. Not only was the waste treated effectively, the solution resulted in an annual savings of $70,000 for the bakery.

Dissolved oils from the baking lines caused a high level of contamination. The plant had previously relied on labor intensive, ineffective water treatment methods like mixing clay into a 300-gallon tank for treatment. The process was rendered useless if plant personnel forgot or the clay would not mix properly. Ultimately, poor program control resulted in non-compliance, excess amounts of sludge and high costs.

EnviroAqua designed a trial to treat the wastewater to make the process less labor intensive while reducing disposal fees. The two product program eliminated the need for clay treatment, immediately saving the plant $30,000 a year. Sludge volume was reduced 50 percent, saving $25,000 in annual costs, and the bakery saved an additional $14,000 by reducing caustic consumption and eliminating the handling of drums and bins.

Aerospace
A major aerospace production plant in California approached EnviroAqua to reduce costs and save millions of gallons of water used in their cooling process. By installing superior water-cooling technology, the plant began saving nine million gallons of water every year while saving $250,000 annually.

This specially designed water treatment program utilized a reverse-osmosis technique that elevated the cooling tower cycles of concentration to levels previously thought to be impossible. Corrosion rates within the circulating water were lowered from 9 MPY to 0.5 MPY. This reduction stabilized the passification of the metallurgy used in the plant process, extending the life of plant equipment and negating the need for replacements.

Pharmaceutical
EnviroAqua partnered with a pharmaceutical plant in California when their management requested an all-encompassing water treatment solution. Our experts provided them with a complete package that included water treatment products, services and recommendations that resulted in annual savings of $722,000.

By completely re-designing the water treatment process within the plant’s cooling towers and boilers, EnviroAqua’s experts were able to meet strict federal guidelines while cutting costs and simplifying plant operations.

Highlights of the successful solution include maximizing tower water cycles of concentration to 5.5-6.0 with the aid of sulfuric acid, cleaning fouled chiller condenser tubes, automating the chemical feed and control, implementing SPC software for system monitoring, and designing a specific boiler treatment program.
