Individual Tests

Test

Sample Size

Liquid

Solid

Total solids are determined by measuring weight loss resulting from dehydrating the sample in an oven under controlled conditions. The percentage of weight remaining is reported as total solids.

The percentage of weight combusted is reported as volatile solids.

25mL

25g

Total Suspended Solids (TSS) are determined through a quick centrifugation of weighed sample, then the resulting supernatant is filtered through a filter paper into a Buchner funnel and subjected to vacuum suction filtration. the Total Dissolved Solids (TDS), the filtrate (filtered liquid) is poured onto a prepared aluminum pan and is dried in an oven overnight. The percentage of weight remaining is reported as the total dissolved solids.

This test measures the pH of respective test samples to inquire optimal pH are within limits

25mL

–

Analysis and quantification in parts per million of volatile fatty acids based on calibrations of known standards.

50mL

–

Measures the amount of dissolved oxygen that must be present in a solution for microorganisms to biochemically breakdown organic materials. BOD is used to measure the waste strength of the respective organic material in question.

300mL

–

Dissolved oxygen that must be present in water to oxidize chemical organic materials; like petroleum. COD is used to gauge the short-term impact wastewater effluents will have on the oxygen levels of receiving waters

The samples are prepared by microwave digestion with nitric acid. Samples are analyzed by Inductively Coupled Plasma-Atomic Emission Spectrometry (ICP-OES) to identify and quantify elements in parts per million based on calibration curves of known standards.

5mL

This test measures the amount of ammonia (bacterial waste) within a sample.

15mL

–

The released SCN generates brightly colored ferric thiocyanate in a concentration proportionate to the initial chloride concentration when ferric ions are present.

15mL

–

To determine the amount of sulfate within a sample using a calibration curve created by known concentrations of sulfate

BIOMETHANE POTENTIAL TESTS (BMP)

A Biomethane Potential Test is a standardized laboratory test to determine the gas potential from a feedstock.

Test

Sample Size

Liquid

Solid

To ensure a sample can provide accurate BMP results; a minimum level of certain nutrients are required. This adjustment adds cobalt; nickel; selenium; molybdenum; and zinc to minimum required levels for BMP testing.

*Requires Trace Metals Analysis to determine current levels

1kg

A traditional BMP, performed with mostly seed, and a small amount of substrate to provide an assumed BMP value. These studies are good when dealing with a substrate that is a partial feed to your AD system, and does not represent a significant feedstock.

500g

1kg

This BMP is our newest product line, simulating a batch plug flow scenario, this HSAD process allows us to understand the biomehane potential in a high solids AD situation, typically for solids that are 30% to 50% solids.

This BMP is performed in 2 L vessels as opposed to 500 ml vessels that both our academic and Industry BMPs are done with. This is typically for low solids wastewaters that are typical with lagoon digesters, or also with feedstocks that need to be heavily diluted to produce a stable biological system

BMP testing must be scheduled in advance with our representatives to ensure timely and accurate results. Reach out to our team to get your BMP testing scheduled now!

Studies

Test

Sample Size

Liquid

Solid

Study to understand biology of a feedstock. Sample will be processed for DNA speciation and categorized by function. This study can help to identify lacking species in the methanogenic process, as well as identifying preferred physical characteristics of existing species.

*Effluent sample required*

1kg

In-depth study to analyze influent and identify ways to reduce H2S production. Testing shall consist of a biological assay to determine microbial speciation and a nutrient panel to identify chemistry imbalances that lead to unhealthy bacterial populations. Results shall be cross-referenced against our microbial database to identify biochemistry adjustments that we believe will reduce H2S yields.

**Note: Digester Doc highly recommends trialing the results of this study prior to full-scale implementation.

2.5kg

An analytical testing and report based on calculations of specific Sulfate components in the feedstock that we than correlate with specific operating conditions and parameters of your proposed AD project to provide H2S levels at 15% COD conversion efficiency, 35% COD conversion efficiency and 65% COD conversion efficiency. This test allows our clients to predict the size and type of H2S treatments that they should employ. As part of this service we provide a high level estimate on what options are available and how they price out for your specific proposed application and needs

A team of experienced digester professionals will assess the key digestive parameters of your anaerobic digester operations and prescribe solutions based on those assessments. This includes an in-depth review of operations; conducting a toxicity & nutrient deficiency screen (TND); performing a baseline BMP to determine current gas yields; a VFA analysis; and additional BMPs as needed to test identified corrective measures.Our optimization study is designed to provide the highest level of service for your digester operations. We offer a 100% money-back guarantee that our optimization study will result in at least a 20% improvement in biogas yields*.
