The wine community is facing a number of challenges, among them, meeting stricter environmental regulations and improving sustainable practices without impacting already strained budgets.
Heritage Systems… delivering liquid solutions
Facultative treatment ponds are designed to hold winery wastewater in contact with bacteria and oxygen long enough for the organic material to be reduced in strength. This process seems straightforward, but there are some challenges to operating a pond. A living biological process is involved, and it is critical that the pH, dissolved oxygen, nutrients, detention time and biology are all in balance. And since these ponds are regulated by the California Regional Water Quality Control Board, land application of the treated wastewater must be documented and meet standards established by the board.
Making a difference in the operation of such ponds is Heritage Systems' PondSentry Aeration and Compliance Management program. At the heart of the system is a PLC-based control, which responds to real-time feedback from a sensor located in the pond, to regulate the dissolved oxygen levels in the pond by turning on aerators.
Since its introduction into the wine community, our PondSentry control has saved, on average, 50% to 60% of the electrical usage and associated electrical costs in pond operation. That’s sustainability!
Best of all there are no capital costs associated with our service. Heritage Systems installs and maintains PondSentry equipment free of charge. You pay a flat monthly fee for our PondSentry Aeration and Compliance Management service. And in most cases, the fee for this service is less than the electrical cost savings achieved with PondSentry.
Living in the midst of abundance we have the greatest difficulty in seeing that the supply of natural wealth is limited and that the constant increase of population is destined to reduce the American standard of living unless we deal more sanely with our resources. W. H. Carother
