Iron is one of the most common elements in ground water. Bythe HN 24:2003 iron concentration in water can‘t be higher than200 μg/l. Water treatment with an acoustic field is a very relevanttopic. Acoustic field is widely used in industrion, medicine,chemical industry and manufacturing. When water is affectedby ultrasound, physical-chemical processes begin. Ultrasoundvibrations lead to dispersion, degasation and coagulation. Ironparticles connect to each other when distance between them istwo times bigger then their own radius. R = 2R. And if thisprocess continues particles connect one by one. In this article teststand and methodics using ultrasonic piezoceramic are shown. Santrauka Geležis – dažniausiai požeminiuose vandenyse aptinkama priemaiša, kuri prastina geriamojo vandens savybes, todėl būtina bendrosios geležies koncentraciją sumažinti iki 0,2 mg/l. Vienas iš geležies šalinimo būdu yra paremtas ultragarso panaudojimu. Straipsnyje glaustai aptarti bendrosios geležies būviai vandenyje, jos šalinimo metodai ir pateikta eksperimentinė metodika. Eksperimentas atliktas naudojant skirtingų dažnių garso bangas nuo 8 kHz iki 20 kHz diapazone. Akustinio lauko daromai įtakai nustatyti, naudojant skirtingų dažnių garso bangas, buvo panaudoti trys skirtingi vandens debitai. Iš gautų rezultatų suformuluotos išvados.

Biomass is organic material, the second most important source of energy. Biomass is a renewable energy source. Wood biomass is used as source of energy for heating in many regions in Slovakia. It is because of its availability. Wood biomass is an easily accessible and affordable source of energy. At present, thermochemical processes, biochemical processes and physical-chemical processes are used for biomass utilization. In the article a suitable technology for combustion of wood chips is proposed. It consists of five main technological parts: transport of wood chips, silo, combustion boiler, and stack.

High strength waste streams, namely rejected water from a wastewater treatment plant, livestock slurry, and agro-food wastewater, are characterized by its high organic matter and nutrient content which favours processes aiming to recover energy and nutrients, instead of removing them. In this regard physical-chemical processes are suitable technologies to attain these objectives. Among others, stripping coupled with absorption, struvite precipitation, membrane separation, and vacuum evaporation, are all physical-chemical processes aiming to concentrate nutrients in a stream that can later be reused as fertilizer. In this chapter the main physical-chemical processes will be defined and described in terms of the objective of each process technique, their theoretical fundamentals, environmental effects (air, water and soil emissions, resource depletion), technical indicators (efficiencies, energy consumption, etc.), and by-product characteristics.
