Distillery and Brewery

Home Domain Domain expertise Distillery and Brewery

The effluent from this industry contains high COD, BOD, pH and total solid content. The typical effluent treatment process includes two significant steps- Bio-methanation and Aeration. In this process UASB (Upflow Anaerobic Sludge Blanket) is used for Bio-methanation. Bio-methanation process is carried out in reactor called Biodigester which converts the organic matter into useful energy in the form of Biogas. This process is carried out in a controlled atmosphere and temperature which results in effective conversion and generates good amount of biogas. Aeration system receives the wastewater from bio-methanation plant and other sources like condensate water and floor washings. The wastewater in aeration system undergoes two types of treatment- Conventional Activated Sludge System followed by Extended Aeration System. The discharged wastewater can be further treated and recycled by employing activated charcoal and chlorination techniques. The characteristics of discharge effluent vary, depending on the product manufactured, the materials used in the process, and the other process details. The typical characteristics of discharge effluent for distillery and brewery industries (indicative molasses based spent wash) are listed in the table below:

Sr. No. Parameter Unit Concentration range
1 Color - Dark Brown
2 Odor - Sugar smell
3 Temperature ºC 80-90
4 pH - 4-5
5 Total solid mg/lit 52000-86000
6 Total suspended solid mg/lit 3000-5000
7 Total volatile solid mg/lit 40000-60000
8 BOD mg/lit 30000-70000
9 COD mg/lit 65000-130000
10 Chlorides (Cl) mg/lit 1000-1500
11 Sodium (Na) mg/lit 40000-60000
12 Calcium (Ca) mg/lit 2000-3500
13 Potassium (K) mg/lit 8000-11000

 

Problems in ETP:

  • High pollution load and have continued to pose a critical problem of environmental pollution
  • High temperature of the wastewaters may instantaneously kill fish and other aquatic organisms, thus destroying the flora and fauna of a river, when the wastewaters are discharged into it
  • High volume of effluent to be handling
  • More chemical usage for neutralization
  • High concentration of readily decomposable organic matters
  • Foul smell due to decomposition of soluble and suspended organic matters present in the waste waters
  • Presence of refractory compounds
  • High operating treatment cost
  • Low yield of biogas due to byproducts

HyCator® Reactor Systems for Distillery and Brewery Industry

HyCa Technologies have a range of products which are environmentally safe and cost effective for effluent treatment of Distillery and Brewery Industry. We generally suggest HyCator® reactor systems to effluent treatment plants in the following manners but it varies as per the client requirements and limitations.

The applications of HyCator® reactor at effluent treatment plant are listed below:

  1. HyCator® MBD increases the digestibility of the effluent in UASB digestor and aerator by breaking long-chain / polymeric/ refractory compounds and thus, reduce the COD and increase the Biogas production. HyCator® MBD can also be installed in the inlet effluent streams (High load) / neutralization tank or recycle stream of effluent, if any.
  2. HyCator® OLM ensures the energy efficient, precise, microlevel, online mixing even at very high flows. It will help to reduce the chemicals in neutralization and subsequent processes.
  3. HyCator® DOB increases the dissolved oxygen content in aerator tanks as compared to conventional surface aerator or diffused aerator and also, increases the activity of microbes by de-flocking them. Thus results in reduction in sludge generation, hence, very less load on clarifiers and less solid disposal issues.
