The strong theoretical background helped us to observe and understand the consequences of the destructive behavior of the industrialized world towards the environment and nature in general. The concern for the deterioration of the environment encouraged us to develop holistic scientific solutions, which could re-establish and restore the natural balance and maintain it in a sustainable way, so that the living standard and health of people will improve.

THE ZET-PRODUCTS WERE BORN

The MUST Technology for Municipal Wastewater

1. The MUST- Approach, contrary to the traditional CBT- methods, is extraordinarily suitable for purifying sewage water, landfill leachate and very toxic industrial waste waters, regardless of concentrations.
2. Large equalizing or other retention ponds are not needed, because the MUST- Approach is not dependent on growing bacterial mass and further removal of bacterial mass that has tied up nutrients. The small footprint saves valuable land area in municipalities, farms and industries.
3. Heavy duty pre-treatment is not needed due to the tolerance of the MUST- Devices to suspended materials and oily and fatty compounds, which compromise the performance of CBT- and RO-Plants. Most waste waters (99% of municipal origin) go through MUST without any pre-treatment, which is a significant competitive advantage.
4. High or low temperature is not a limiting factor for the MUST- Method, which operates from +1 to + 99 C° without temperature control.
5. MUST- Method can work within a broad range of pH (6,0 – 9,0). If pH of the incoming waste water is below 6,0 or acidic, it has to be adjusted or neutralized to fit into the Window of Tolerance.
6. A short retention time and no dependency on slow biological processes make it possible to quickly adjust the MUST- Process against fluctuations in the incoming process water.
7. MUST eliminates all toxic pollutants from sewage and landfill leachate. The odor disappears after the MUST- Purification, too.
8. The complete phosphor removal is based on the fact that the metallic iron electrode donates ferric ions (Fe³⁺) that precipitate the soluble phosphate-ions quantitatively without adding pernicious (iron) sulfate, which is heavily loaded from the CBT plants to natural waters. Sulfate from the CBT Plants will be converted into extremely toxic hydrogen sulfide, which destroys the Marine Ecosystem permanently.
9. Phenol and poly-aromatic hydrocarbons (PAH) and their poisonous and carcinogenic halogens (also PFC, PFAS, PFOA, PFOS, GenX) break down in the MUST-process when the benzene ring and carbon fluoride/chloride bonds break down. The neutralized disintegrated components are entrapped into the
floc and removed for elimination.
10.The MUST- Plant are built into the 20 feet sea containers or in any open room, where the modular structure allows flexible capacity from 10 cubic meter/d up to 1 million cubic meter/d. All pollutants separated from the waste water are in the floc, and therefore the floc should be treated as a problem or toxic waste in most industrial cases.

The MUST Technology for Animal Husbandry
A facility that includes both the MUST Water Purifier and the Chemostor Bio-Oxidizer produces pure water and hygienic, odor free and chemically stable soil conditioning Natural Bio-Fertilizer. In this MUST- Process, all nutrients are recovered into Bio-Fertilizer without loses to air, water or into soil. This technology is used for converting agricultural waste by profitable means into valuable, commercial commodities for sustainable life.
The MUST Technology for Chemical Forest Industry
By replacing the traditional CBT Plants of Pulp and Paper Industry with the MUST Technology, the warm process waters are purified and returned back into the beginning of the process, thus reducing heat losses and replacing cold, fresh incoming water. The MUST Process eliminates the creation of sludge and turns the suspended and dissolved material from the processed waters into a solid self-drying floc. The purified water from the MUST Process is slightly on the alkaline side, does not contain bacteria or viruses and is therefore ideal for producing packaging materials in direct food contact. The ZERO Emission Waste Water Effluent is achieved.

The MUST Technology and ZET Products for Mining, Gas, Oil and Coal Industries.

For oil industry applications no heavy duty per-treatment is needed due to the tolerance of the MUST- Devices to suspended materials and oily and fatty compounds. In coal, oil and gas explorations, production and refining, the naturally occurring radioactivity causes a special health risk when dealing with Produced Water. Uranium and the trans-uranium elements from organic-free mine mineral waters is an exceptional procedure compared to the purification of any other waste water. In the MUST Reactor all metal elements form hydroxides and precipitate with iron and/or aluminum hydroxides created in MUST Cell. In dilute, mineral rich mine water, a specific matrix has to be added to facilitate capturing Uranium and trans-uranium elements of very low concentrations.

Radioactive isotopes may occur in gas or solid form. Uranium 238 is the most common radioactive element on Earth. Its half-life is ca 4,5 milliard years, and for some of its isotopes several hundred thousands of years.The average concentration of Uranium isotope 238 in mother rock is ca 5 ppm, but it may occur in higher amounts. Uranium is a common side product element in almost all mining operations and appears as a pollutant in process waters.Uranium and the trans-uranium elements are chemically very toxic, and not only because of their radioactivity. The radioactive decay produces many radioactive daughters, such as Radon gas, which is an Alfa particle emitter and exposes to lung cancer. Therefore, it is imperative to remove Uranium and other radio-isotopes from mining waste waters and remove and save them into insoluble form.MUST technology has been used successfully to remove Uranium for example from waste water of Phelps Dodge Copper mine in Arizona, USA, 2007 (from 2160 micro gram/l to 0,19 micro gram/l), from process water of Talvivaara/Terrafame Nickel and Zinc mine in Finland, 2012 (from 330 micro gram/l to 0,10 micro gram/l) and from process water of LKAB Iron mine in Kiruna, Sweden, 2020 (from 15,8 micro gram/l to 0,04 micro gram/l). With MUST Technology radioactive waste water can be processed, radioactive isotopes removed, isolated and saved permanently and safely.

Removal of Radon from drinking water:
The set limit of EPA drinking water standard for combined Uranium isotopes 234 and 238 is 30 pCi/l and for all Uranium isotopes 30 micro gram/l. In Uranium rich terrain, Radon gas leaks to ground water and into buildings if they are not properly insulated. The set limit of EPA drinking water standard for Radon is 300 pCi/l. In addition to Uranium and Radon, there are set limits to Radium-isotopes 226 and 228 (5 pCi/l) in drinking water standards.
A special method and equipment (RADOX) has been developed in 2002 to remove Radon gas out from drinking water and fix it into activated carbon for final storage.

LIFE WITHOUT LANDFILLS by an anaerobic therm-o-chemical cracker (TCC)

ZEP-PYROLYZER® – The anaerobic therm-o-chemical cracker (TCC) that processes organic waste through enforced convection thereby recovering pure carbon black and heat energy. The initial objectives of the innovation are:
• To develop alternative solutions for waste processing with the aim to avoid the use of landfills.
• To break down all organic waste to solid carbon, and separate and recover it with other pure elements
• To eliminate waste with positive material and energy balance
How it works:
The ZEP-PYROLYZER is a processor in which therm o-chemical decomposition of organic material at elevated temperatures takes place in the absence of any air. It involves the simultaneous change of chemical composition and physical phase, and is irreversible. Providing the material and energy balances are positive, the ZEP-PYROLYZER is a feasible solution for the elimination of landfills and the production of carbon and other pure elements and energy. This means that the waste material introduced into the ZEP-PYROLYZER has to be dry and free of oxygen. The recovered carbon has to be in elementary form and not be converted during the process into carbonaceous compounds containing carbon polymers. This is achieved by the enforced convection method. The combination of Jet Milling, ION PARTICLE CLASSIFIER and MUST- technologies are needed for the ZET-pyrolysis process. The produced pure elementary carbon can be used as a valuable raw material for tire manufacturing or as activated carbon for purifying drinking water and air. The energy content of the produced and recovered pyro-gas is higher than the energy needed to release it from the organic material. The material and energy balances are positive. As a consequence, ZEP-PYROLYZER is a waste power plant – a carbon sink -, which will convert all waste material to energy and to valuable commercial commodities. When there are no landfills, there are no emissions to air and no toxic landfill leachate into ground water. ZEP will have, hopefully, a dramatic impact for decreasing the human role in climate change by capturing toxic elements and reducing greenhouse gas emissions.
