The achievement of modern science discovered many aspects of the nature that give the ability to reflect deeply to the root of our existence. Dynamics plays a crucial role in micro scale of object, and according to the Heisenberg principle, the exactness of the small object can be expressed only by probabilities. The nature of small objects can also be the main constituent of the bigger object in nature. This makes the stability of bigger objects to a certain extent depends on the microscale´s nature. Along with the progress in science, philosophy shitfts the direction of its topics. Subjectivity comes forwards but the objectivity is not put aside. These two alternate during the time as the consciousness plays ist role. The beauty of nature is then seen more and more clearly, in „order“ as well as in „chaos“. The micro nature is the new subject in science, and fenomenology in post modernism is also the field of today´s philosophy.

The development of science and technology cannot be excluded from the human thinking in modern world. One of the major problem which echo comes and goes along the time is the what so called "dilemma of determinism", which is also associated inclusively to the problem of God's existence. Natural science brings a deep implication in thinking leading to determinism of human being as a part of the nature and moves together with the natural processes, that flows according to the natural laws without human decision. But modern science which development is accelerated by the combination of concepts in physics, chemistry and computer, explains that the previous natural laws do not apply in micro systems and the quantum mechanics takes over to rule the behavior of elementary particles in atomic scale. Then modern concepts in science aroused: chaos, complexity, dissipative structure, fractal, which speak about irregularity, unpredictability, then a causality of things that rooted deeply from the microscale dynamics, are expected to be one way out which provides a "chance" which in turn still offers a place for human freedom.

Surfactants are organic materials that act as active ingredients in detergents, soaps and shampoos which can reduce the surface tension of the water so that the particles attached to the materials being washed are released and float or dissolved in water thus polluting the environment. Therefor it is necessary to separate or change them into other harmless materials before being discharged into the environment. One of the methods used is electrocoagulation. The electrocoagulation method is an environmentally friendly method of treating liquid waste by combining the principles of coagulation, flotation and electrochemistry. In this study, the electrocoagulation method was carried out by varying pH and electrolyte concentrations in the simulated surfactant waste treatment. Surfactant levels were determined by spectrophotometer in methylene blue. The optimization of the method is done by determining the maximum absorption length, optimum pH, and the effect of adding electrolytes with different concentrations. The results showed that the maximum absorption at a wavelength of 659 nm. The electrocoagulation process runs optimally at pH 2 with the addition of 7mM Na2SO4 electrolyte resulting in a% removal of 65%.
