Coagulation is an intermediary step, but it is essential to the physico-chemical treatment process of water and wastewater. This is the first step in the elimination of colloidal particles and its main function is to destabilize the particles. This destabilization is essentially the neutralization of the electrical charge present on the surface of the particle thus facilitating the agglomeration of the colloids.

Lubrico - A.Tsakalis Ltd. is producing a wide range of organic and inorganic coagulants based on ALuminium and Iron Salt, such as :
- Polyaluminium Chloride
- Polyaluminium Chloride Sulfate
- Aluminium Chlorohydrate (ACH)
- Aluminium Sulphate
- Ferric / Ferrous Chloride
- Ferric Chloride Sulfate

All products are certified according to the European Community Standards for application in potable water and therefore correspond to standards of EN 878:2004 and EN 883:2004.

Lubrico - A.Tsakalis also manufactures a wide range of organic coagulants based on several chemistries such as polyamines, polydadmacs and blends. They can be used alone or in combination with aluminium base inorganic coagulants, providing a consumption reduction of a 20-40%, reducing dramatically coagulation times, not only succeeding in reducing the treatment cost but also reducing the volume of the treated sludge and their disposal cost.

Lubrico - A.Tsakalis Ltd can provide three main categories of organic coagulants to the market :
- Dicyandiamide resins (Lubrofloc ECO series)
- Polydadmac (Lubrofloc PD Series)
- Polyamine (Lubrofloc PA Series)

The efficiency of coagulation and flocculation will greatly determine the success of your entire treatment process. With this being the case, proper and effective flocculation should be a priority for every operator. Flocculation is the accumulation of destabilized particles into microfloc and later into bulky flocs.

It is important that sludge volumes are kept at a minimum with a high dry-solids content to reduce disposal costs. Our customers report success cases in sludge dewatering where we have significantly increased dry solids. This gives direct benefits not only in reduced costs, but also by increasing the dewatering unit capacity at the same polymer dosage.

Lubrico - A.Tsakalis can offer a full range of polymers, combined with monitoring and optimizing solutions and extensive application knowhow. Our approach to enhanced sludge dewatering includes technologies for smart process management and enables the optimization of chemical consumption, always delivering the best dewatering performance.

Our product line in polyacrylamides, can vary for different Molecular weights and charges in order to cover multiple applications :

- Cationic Dry Polymers
- Cationic Emulsion Polymers (Linear / Cross Linked )
- Anionic Dry Polymers
- Anionic Emulsion Polymers
- Partially Hydrolized Polyacrylamide (PHPA)

Lubrico - A.Tsakalis Ltd. has introduced a new product line based on Nanotechnology. Its main application is on municipal wastewater treatment plants where can replace all common coagulants with many side positive effects. Integrated metal oxide nanoparticles are bound to special organic charge carriers and trigger the required chemical reactions in the sewage plant at incredible speed.

The main benefits of the products:

- The products are inorganic compounds, therefore no affect on the bacteria of the system
- Cost of chemicals up to 0.01 e / m 3
- Better SVI , therefore much better water outlet parameters (COD, BOD , TSS, TP, TN)
- Due to fast sedimentation, we can maximize of the capacity of the plant if the hydraulic are proper
- Due to the formulation of big stable flocs, plant can achieve the reduction of min. 4% in consumption of polymers for the thickening units.
- Due to formulation of stable flocs , plant can achieve faster Nitrification / De - Nitrification process, therefore significant amount of air in the blowers can be reduced. That means a significant cost reduction and an increase in the life span of the compressors.
- Plant can receive the max. of organic sludge of the system therefore produces the max. biogas, as a result the electricity consumption from external sources can be minimised.
- Dosage of the chemical up to 4 ppm.

Hydrogen Sulfide (H2S) is a dense, colorless, strongly odorous toxic gas that corrodes infrastructures and impairs the performance of wastewater treatment operations. Hydrogen Sulfide is naturally converted to sulfuric acid which is corrosive towards steel and concrete. Control of H2S will result in increased life and lower maintenance cost for facilities and piping. In addition, worker safety, is of concern as Hydrogen Sulfide is extremely toxic at levels above 500 ppm, which can be reached in confined spaces.

For this reason , Lubrico - A.Tsakalis Ltd. has been developed the product LB CF 300, which is a highly concentrated nitrate solution to which special iron components are added. The result is a combination system with dual effective properties. On the one hand it prevents the emergence of anaerobic conditions; This prevents the formation of hydrogen sulfide and other odorous, volatile and not uncommonly highly toxic substances that can form only with the exclusion of oxygen.

LB CF 300 effectively combats already existing odorants, even amines and mercaptans. These often extremely foul-smelling substances are immediately bound and neutralized. The product suppresses the formation of biogenic sulfuric acid, which, due to its aggressiveness, leads to extensive corrosion damage to the entire wastewater infrastructure. This significantly reduces the costs for maintenance and repairs in the sewer system. Further to its capabilities, the calcium content stabilizes the flakes and supports the biological processes on the wastewater treatment plant. Digestion processes are avoided, the sludge properties improve.

Lubrico - A.Tsakalis Ltd. has been active in the development and marketing of products to solve environmental problems and maintain ecological balances through the use of safe and natural bacteria.

Applications :

- Control Fats , Oils and Grease (FOG)
The enzymes produced by certain strains of bacteria (3) break down grease, soap, and other organic matter in the drain, enabling the bacteria to fully digest these elements. The coating of waste in the pipes thins as a side effect of bacterial feeding, thus opening the pipes.

- Control Ammonia, Nitrite
Strains of Nitrobacter winogradskyi and Nitrosomonas europaea, with superior talent for rapid nitrification under aerobic conditions.These autotrophic microbes inefficiently use the energy gained from oxidizing ammonia to fix carbon. This activity gives these bacteria a dual ecological role - recycling nitrogen and fixing carbon into organic compounds. Carbon fixation by this method is not very efficient, because the fixation of one mole of carbon requires the oxidation of 35 moles of ammonia to nitrite and of 100 moles of nitrite to nitrate.

- Bioremediation of oil spills and Drilling Mud
Heavy hydrocarbon concentrations such as those resulting from an oil spill or oil slick are detrimental to waterways, wildlife habitats, and farming, etc. If some sort of remediation is not tried, petroleum wastes will invariably reach fresh ground water supplies or aquifers

- Reduction of waste disposal
Lubrico - A.Tsakalis Ltd. provides a product that almost completely eliminates organic solids, thus reducing or eliminating odors and saving major operational and disposal costs for plant. The product is a combination of many specifically selected bacterial strains which are combined with proprietary nutrients during the patented manufacturing process. Many of the initial strains are utilized by the three key microbes that become dominant during the process.

A boiler water treatment function is to keep heat transfer surfaces (steam-generating and associated tubes) free from scale and deposition. The second function is to inhibit corrosion. Boiler deposits are problematic because they typically contain undesirable levels of metal oxides, mineral scale, sludge, or various combinations. Corrosion generally occurs because of excessive levels of dissolved oxygen, but can also develop under tube deposits. Deposits and corrosion can lead to boiler tube failures that result in costly repairs and downtime.
