What Happens in Large Egg Shaped Tanks Often Seen at Municipal Wastewate...


The big egg-shaped containers you see are "digesters," which are used for anaerobic digestion.

Anaerobic digestion is utilised in wastewater treatment facilities to stabilise both main and secondary sludges that settle out during aerobic wastewater treatment (Sewage Works).

The major output is biogas, or biomethane when cleaned up, which is a valuable renewable (mainly methane) gas.

The gas can be utilised to power the wastewater treatment plant's machinery and offices, and there may be enough left over to serve local houses.

The sludges contain a solids concentration ranging from 2 to 6% (that is, 20-60 grammes of Total Solids per litre).

Around 70% of the combined sludge is degradable, and in a normal single-stage CSTR reactor, up to 80% of it is digested, lowering the TS by roughly 50%.




Although mixed sewage sludge has a high concentration of carbs, lipids, and proteins, it is infamously difficult to digest.

The most recent designs of these facilities frequently incorporate a pre-treatment stage in which the entering sludge cells are broken apart to allow them to be digested more readily and quickly in the digester.

Twister Food Waste Depackager Separator is a Breakthrough in Vortex Flow

New customers in Europe and Asia have purchased Twister's innovative food waste de-packager and separator. This small-footprint, low-energy consumption plastic waste reprocessing facility has established itself in the increasing EU and Asian markets.

Since 2016, it has been in the works. An organic processing system with exceptional separation performance was recently shown in Canada.

This device ejects each open, empty, and completely emptied containers. Plus, with the "Twister" effect, the clean food waste generated is free of microplastics and is suitable for anaerobic digestion

Founder and CEO Mark Vanderbeken adds, 

"We wanted something unusual for Drycake's twister."

A food waste depackaging expert would have seen that "everyone tends to begin their depackaging and separation of source-separated organics by reducing particle size." ' This is a common tactic used by competitor depackagers to minimise congestion. It is milled, macerated, chopped, or shredded to get the plastic into smaller pieces. Why not combine the depackaging and separation stages? However, larger pieces are easier to separate than smaller ones.

In response, DryCake went back to the drawing board and devised a method that does not require cutting and does not rely on processing plastic by reducing its particle size. Instead, they open and remove organic material in an extremely high-speed vortex using shear forces and vibration such that they do as little damage and produce as few microplastics as they possibly can.

Consequently, it is a market leader in sustainability by reducing the environmental damage that plastic pollution causes. "Ocean microplastic ingestion" is damaging ocean plankton and the food chain that supports all marine life, hence Drycake decided to take this course of action.

A lot of energy is required to cut, smash, and crush these materials. It is necessary to replace all moving components of hammer mills, knives, and blades. As a result, there are few moving parts in the Twister.



To the extent possible, plastic packaging should be avoided wherever possible."

As a result, you won't manufacture the microplastic particles in the first place. So, microplastics generation and energy consumption are lower in the Twister Food Waste Depackager and Separator compared to its competitors.

The reason Drycake predicted that this invention would be in high demand from the beginning is because of this fact. This company has a great opportunity to disrupt the business and become the industry standard depackager provider in Europe and Asia, with considerable environmental advantages.

One of their main goals is to help their clients manage sustainable plastic recycling operations, reprocessing plastic waste for use as resin in new packaging in the "circular economy," which is essential to avert catastrophic climate change. A high-quality organic paste for biogas plants at the same time

Anaerobic digestion plant operators may use this precious paste or "organic soup" as feedstock to generate sustainable energy in the form of biogas refined to biomethane. To put it another way, compressed biomethane is known as Renewable Natural Gas (RNG), and it may be used to heat our homes.

Additionally, it may be used as a low-emission vehicle fuel while hydrogen technology is in the process of being developed.

Since its market is much larger than that of the city or regional MRFs and ERFs (Energy Recovery Facilities/Incinerators), the Twister concept is also innovative. Reduced RCV travel distance, reduced collection costs and emissions, and improved food waste collection efficiency are all advantages of the smaller container size.

Waste collection employees will spend more time on the street collecting rubbish and less time sitting in the cabs of their RCVs on their way to the MRF ERF or transfer station by dispersing Twister unit locations. The facility and the process may also be designed by Drycake if necessary.

Clients should be pleased with the low energy use, low carbon impact and minimum maintenance required by Twister. Green characteristics make it an attractive investment for years to come.

Twister is a great option for supermarkets, organisations, and institutions that handle catering facilities, as well as clients in the food and beverage industry. Consequently, their company's carbon footprint is reduced and they may exhibit their true green successes for many years to come.

It's always a risk to try anything new, but they think it's worth it. The preservation of the global environment and the creation of a product that aids in the attainment of Net-Zero Carbon 2050 emission goals are among the primary reasons for this action.

How Twister's Vortex-Based Food Waste Depackager Beats Its Rivals in the Market

In at least four ways, Twister Food Waste Depackager technology does this:

Combining two separate tasks into a single operation saves both energy and water.

For example, if producers utilise virgin plastic resins rather than recycled plastic resins, they are emitting much more "greenhouse gas" carbon.

In order to create sustainable energy with low net carbon emissions, the biogas plant can be fueled by a plastic-free paste or slurry made from food waste. As a result, there is less need to extract oil or gas from the ground.

Reduces carbon emissions by reducing the farmer's demand for chemical fertilisers when organic slurry is digested and spread on agricultural land. Traditional fertilisers rely on the extraction of minerals from the earth's crust. In order to harvest and transport them, they need a significant amount of fossil fuel. This notion, thus, contributes to preserving the environment.

Their separation solutions have made them an industry leader for more than a decade. After starting out as a supplier of process equipment and design for trash recycling, reuse, and recovery, it has grown into a global industry leader.

Drycake has a history of violating the rules. Prior to the Plastifloat's debut, they made headlines for their efforts to recycle municipal garbage and recover materials from industrial effluent streams. One of the most effective methods for removing plastic from water.

Currently, Drycake is selling their Twister Food Waste Depackager throughout Europe and Asia, in addition to its previous sales in the United States. Interested readers can visit https://www.twisterseparator.com for further information.
