In conventional environmental protection the parallel development of advanced technical solutions alongside ever more stringent environmental standards increasingly conflicts with the moral and practical imperatives to ensure sustainability and drastically improve the life conditions of the world's poor. Such priorities are far better tackled by technological and social innovations based on relatively simple and highly sustainable concepts: e.g., applying Natural Biological Mineralization Routes (NBMR) for wastewater and waste treatment, implementing Decentralized Sanitation and Resource Recovery and Reuse (DESAR3) where transport of waste(water)s is kept to an optimum level and pollutants valorized, etc. With developing countries now taking a lead in applying these concepts in public sanitation, the more prosperous countries will gradually abandon the expensive, vulnerable and non-sustainable conventional approaches to wastes treatment and environmental protection.

Rising environmental standards for treated waste water necessitates to improve current waste water treatment methods or to look for the new ones. Often this task is rather difficult because new or modified methods have to be investigated thoroughly and the main parameters for process modeling and effectiveness estimation have to be set. Biomass concentration in biosorption process is important technological parameter though there is no accurate technique for its estimation. Thermal dissociation technique to determine biomass concentration was developed as an alternative to the standard volatile suspended solids (VSS) method. Biomass content is important for the technological calculations of the system, estimation of the oxidation potential and for the evaluation of biomass growth in accordance to decomposed pollutants, etc. Thermal dissociation technique is based on the difference in the sorbent and biomass burn out temperatures. The biomass content research results are given for sand, gravel and for activated carbon BAS-A.
