DAF (Dissolved Air Flotation) device is used for separation of  dispersed and suspended particles from wastewater. Flotation is a mechanical separation proccess based on making supersaturated air solution in wastewater, meaning that micro bubbles make contact and connect with suspended substances and enable them to reach the surface and float.The air is being dispersed from the bottom of the pool, t it “collects” particles on it’s way up and pushes them to the surface. Coagulant neutralizes the electrostatic load of colloid particles and enables their agglomeration into floccules. Polyelectrolyte connects the neutralized particles into even bigger floccules. Piping saturator has a unique construction and enables air bubbles with dimensions 10-70 micrometers, what provides an extraordinary efficiency. AREAS OF APPLICATION AND MAIN APPLICATIONS Milk industry, ice cream production, juice production, alcoholic beverages production, breweries, fish and meat processing, fruit and vegetables processing, drinking water, etc. Plastic recycling, chemical industry, oil and gas, textile industry, leather industry, laundry services, package washing etc. Advantages of our DAF Systems: - Very high level of reduction of pollution parameters Suspended substances Reduction rate from 90-99% Oils and fats Reduction rate trom 90-99% BPK5 Reduction rate from 70=80% HPK Reducstion rate from 70-80% - Comprehensive and efficient solution which provides high stability and efficient removing of dirt. Reliable method for refining of technological wastewater. - Simple installations provide compact equipment set and saves space. - Major savings because the system construction and technological parameters ensure small consumption of energy, air and chemicals. - Very stable functioning of coagulation, neutralization and flocculation systems. - Law level of turbulences, there is no re-retraction of floating sediments. - We have available a developed digital services package which provides follow-up and optimization of the DAF system long-distance working and remote controllie of thesystems. - Instead of classical lamellas, we use special “U” profiles which provide: Separated flowi of wastewater and clean water Equal distribution of wastewater flow and sectors load, decreasing the turbulence There is no obstruction of flow of flotants Flow leaders secure less consumption of polymers DAF is a device made of stainless steel We can deliver complete systems or rebuild and upgrade existing DAF devices.

Filter plates at Mebrane filter press are equipped with membranes that enable additional "squeezing" -dehydration of the filter cake. Increasing the filling pressure ensures precompression and drainage of the filter cake in the chamber. When the filling pressure reaches a predetermined value (approximately 6-8 bar), the filter cake is additionally exposed to the membrane pressure, and additionally "squeezed". Elastic membranes, which can be made of polypropylene (PP) and synthetic rubber (NBR, EPDM), use compressed air to press the filter cake over the entire surface of the chambers. Additional compression thus expels free water through the filter cloth. ADVANTAGES OF MEMBRANE FILTER PRESSES: •  More economical filtration due to high degree of drainage and shorter cycle time  Maximum flexibility for expansion and automation possibilities  Extended pump life in the case of abrasive media, due to low supply pressure CASE STUDY:  Delivery of membrane filter press with the dimensions of plates 1000x 1000 mm, 36 plates, volume 770 liters, for filtering the solution of lead "paste" in the process of battery recycling. Investor "TAB MAK".  The press is equipped with: membrane plates with EPDM membrane, system for automatic opening of plates, "Squezing" system for additional dehydration of filter cakes, "drip tray" system. Degree of dehydration of filter cakes: 80-90% dry matter..
