Filter Brewery Wastewater to Reduce Disposal Costs and Save Water

Brewery wastewater is not easily disposed of and can be a major operating expense. This dilute wastewater is mainly composed of water, grains, and fermentation by-products which can result in high surcharges when disposed of in the sewer system. For plants not connected to a sewer, the cost to haul wastewater to nearby processing locations can be steep.

Digested Organics specializes in organic waste management and provides customized solutions to help breweries take care of their wastewater. We offer a unique stainless steel ultrafiltration system, which can remove suspended solids, a fraction of the organic matter, and large fractions of the nitrogen and phosphorus. See the below data table for a brewery wastewater sample we recently put through the ultrafilter, along with the picture of the raw wastewater, filtrate, and concentrate.

 

For customers that want an even cleaner effluent, we use our Two-Step Reverse Osmosis System.  This is a combination of forward and reverse osmosis that produces very clean water that just has trace amounts of sodium–ideal for reuse onsite, direct or indirect discharge, or sewer disposal with little or no surcharges. Below is a representative data table as well as a picture showing the raw wastewater, the TSRO concentrate, and the clean water effluent.

 

 

Avoid Winter Manure Spreading with Advanced Filtration

During winter, manure is applied on accessible fields or parts of fields that are available depending on weather conditions. This is known as winter manure spreading. Winter manure spreading is a practice that is intensely scrutinized and regulated because of the high risk of polluting water sources and loss of nutrients. The risk of runoff to surface water increases when manure is applied to frozen or snow-covered ground, and this runoff can spread contaminants like phosphorus and nitrates.

Typically, the greatest risk of runoff and nutrient loss occurs within 72 hours of rain or snowmelt. With climate change causing more dramatic rain events, the risk of runoff and surface water contamination is only rising.

Luckily, you can potentially avoid winter manure spreading with customized filtration technology from Digested Organics. By removing liquid from your lagoon year-round, the chance of needing to spread manure in the winter due to a full lagoon is dramatically reduced.

Digested Organics deploys a stainless steel ultrafiltration system and Two-Step Reverse Osmosis system that can dramatically reduce the volume of liquid in your lagoon as well as help concentrate nutrients for more cost effective land application. When deployed together, we call this our Nutrient Concentration & Water Reclamation System. With these filtration solutions, you can:

  • Reduce manure hauling and spreading costs
  • Reduce the risk of manure hauling spills, road deterioration, and soil compaction
  • Prevent groundwater contamination and reduce odors
  • Manage nitrogen and phosphorus levels to allow farmers to expand operations
  • Customize a solution to meet your site’s specific needs

The systems built by Digested Organics can turn manure into clean, reusable water and concentrated fertilizer that is ready to be land applied when it makes the most sense for your crops and not when your lagoon is simply full .

Digested Organics Prevents Manure Lagoon Overflows

This fall, Hurricane Florence’s rains flooded a large area of North Carolina that included many hog farms, causing overflows of the manure lagoons. These overflows raised serious concerns around pollution and questions about the best way to deal with hog manure.

Situations like this could be prevented in the future with the use of Digested Organics’ waste management solutions. Our customized stainless steel ultrafiltration systems can turn manure into a filtrate with little to no suspended solids, bacteria, and phosphorus, while simultaneously creating a high value concentrated fertilizer for more targeted land application. For sites that want to remove water from lagoons and directly discharge it to nearby waterways, we use our Two-Step Reverse Osmosis System to polish the UF permeate, creating crystal clear water for discharge (or reuse) and a second concentrated fertilizer. Used together, we call our integrated filtration package the Nutrient Concentration & Water Reclamation System.

Digested Organics’ products are customized to the farmer’s needs and have proven to be better for the bottom line and better for the environment. Give us a call at 844-934-4378 to learn how we can help you improve lagoon and manure management today.

Filtering Thin Stillage Beats Evaporation

the 

Are you evaporating thin stillage? We can filter it instead at a fraction of the cost! Our stainless steel ultrafilter recovered ~75% of this thin stillage as a clarified filtrate with no suspended solids and significantly reduced nutrient content.

Key benefits:

  • UF permeate is ideal to reuse as backset since it contains no oils, no bacteria, and fewer volatile acids
  • Increases the amount of thin stillage usable as backset
  • UF concentrate is a higher solids slurry for incorporation into DDGS and reduces energy required for evaporation
  • May increase efficiency of corn oil recovery by reducing oil recycled in raw thin stillage to fermenters

Digested Organics partners with Gryphon Environmental to deliver cost-effective drying solutions

Digested Organics is pleased to announce a partnership with Gryphon Environmental to supply high-efficiency dryers for farmers looking to reuse manure solids as bedding or produce dry feeds.  By using the biogas generated by the BioEliminator™ manure treatment system, a Gryphon Dryer can create significant value for farmers looking to bed with dryer solids (good for reducing somatic cell counts) or produce their own dry feeds from wet materials like gluten or distillers grains.

Digested Organics selected the Gryphon Dryer because its performance is the best in the industry, with a 40% improvement in both operating costs and capital costs over competing technologies.

The Gryphon Dryer injects compressed, heated air into a vacuum that acts to simultaneously evaporate and physically remove water from wet materials.  The dryer operates with a closed-loop air system, meaning the air used during the process is dried and re-circulated to take advantage of existing heat and to reduce energy consumption.  The condensate water can be released to the farm’s lagoon or optionally purified for reuse.

For more information about how Digested Organics can integrate its cutting-edge digestion technology with a Gryphon Dryer, please call us today (844-9-DIGEST) or email at info@digestedorganics.com

Demonstration Unit Winterized and Running Well!

The demonstration unit at the Wagner Dairy has been fully winterized so we can keep it running for the next several months in Wisconsin’s sub-zero climate.  In addition to insulating the container housing the treatment tanks, we have insulated and heated all the lines and the BioMicronizer pump and nozzle.

The latest data from the demo unit has continued to show exceptional treatment efficiency, with very high rates of organic matter conversion to biogas and removal of total suspended solids and phosphorus.  For a complete analysis, please download the latest report.

BioEliminator™ Demonstration Unit Moved to Wagner Dairy Farm in Middleton, WI

The BioEliminator™ demonstration unit was moved at the end of August from Michigan State University, where it was treating digestate, to the Wagner Dairy Farm in Middleton, Wisconsin.  The unit is designed to treat between 150-200 gallons per day of liquid dairy manure. Since the BioEliminator™ arrives onsite pre-assembled and ready to plug and play, it was quickly commissioned and is currently processing the liquid discharge from the Wagner’s screw press separators.

The liquid manure is prepared for treatment using our BioMicronizer™ process and then passes through the BioEliminator™ system. Within 3 months, we anticipate the unit will produce biogas containing 80% methane as well as a greywater effluent containing very low levels of organics, nitrogen, and phosphorus.

Please come visit our demonstration facility during the World Dairy Expo (Sept. 30th to Oct. 4th) or by appointment.  Please contact COO Chris Maloney for more information or to schedule a visit at chris.maloney@digestedorganics.com.
