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 .
